Sneak Peak At Our Next Project

As you might have heard, Project Roadmaster is in another stable and doing well. I've been working on our new project and it's something different entirely, but something cool and valid and has a place in hot rodding, especially in our present times. Another often over looked platform and a hoot to drive.

Hint: after the practical flag waving ending of my last post, it's NOT the American ride. It's simply...the most interesting practically free hot rod in the world. 

More coming soon.

Project Buick Roadmaster Part 8: The End Result

Hi all,

Well, it's time to send off a car that was such a good conveyance, one wants to talk about it almost in terms of a friend.

Bought off of Craigslist for $1000, minor investments in getting the car roadworthy for a cross country trip to New Orleans - two grown men, a pit bull, two lives worth of crap stuffed into one car - and we got there, comfortably, in style, plenty of power to blow past a few V6 Mustang dorks despite the huge payload on board.

The car got impounded once in New Orleans, we had to work twice as hard to both survive and pay for daily expenses and put away money for the impound fee - we had to get to LA, as there wasn't enough time left in the season to establish ourselves in NOLA just yet.

Long story short, we got back, now bringing yet one more person and their stowage (don't ask) to LA.

We averaged 23.4 mpg between the two cities. Traveling at an average of 70mph, 4200lbs dry, 5.7l V8, 'dinosaur' technology and all that, laden with no less than 1000lbs of humans and dogs and belongings.

Do that in your CRX, sir.

And before someone says 'minivan', let me remind you that I got us one of the last parking spots within any kind of walking distance on Mardis Gras day proper, and probably wouldn't have gotten it if I couldn't have gotten the crowd of drunken dipshits to part near Frenchman St. Laying the horn didn't do it - but lighting up the rear tires and that accompanying police car engine growl sure did!

So yeah, nyahh to you, too, Mr. Minivan. Also, if I'm going to be mistaken for something I'm not, I'd rather be mistaken (most times) for a pimp rather than a henpecked dad.

Not happening in Camarobird or Mustang, either.

None of the cars besides the minivan can slip through traffic as a Q ship, either, at least in stock form.

Just sayin'.

ROAD-MASTER!

The car has an impressive pedigree, and the design, rather than being 'archaic' as some detractors would suggest, simply proved it's worth and ability by surviving four decades of automotive history, and time proved the design strong and tunable for handling as well. After all, the Chevy 9C1s went as fast as 138mph in stock trim - do you really think the car is such a pig that it can't handle those speeds? Trust me, ask a cop who has driven both. Ask someone who has RAN from a cop in both.

As 'dowdy' as the stock, high riding, baloney wearing stock setup was, it was more in line with the Police philosophy- being able to go over any surface, quickly, reliably. Real roads, not race tracks. And still could hit all 109mph or so of the factory limited top speed in a little over a quarter mile.

Buick itself has often had some of the most potent engines and sturdy, durable technology available - it is in a real way America's answer to Mercedes Benz for over 100 years, the reason we have Chevrolets (Louis Chevrolet was a Buick racer), and was a middle point between working class Chevys and opulent Cadillacs.

As a matter of fact, when people would recognize me as the owner, often I'd here 'oh, you're the guy who owns the Cadillac, right?'

Anyway, once back on LA soil I was backed into in the Whole Foods parking lot. Awhile later I was paid insurance on the damage, but being pragmatic and a body guy I just pushed the dent out and lived with the fact that I'd have bought the car with the damage for that money anyway.

I was also now in the interesting head space of 'you know, technically I have -$200 into this car right now. I've actually made money owning it, in a way.'

So I ended up going what, for me, was whole hog. I wanted it to look like the Impala SS cousin it was, I wanted to handle like it was the SS cousin that it was, and I wanted it to sound off like it had a pair. The car was so responsive to really cheap and easy mods that I'm surprised they can still be had at this kind of money.

My test grounds this time around weren't Bouquet Canyon Road, which has become a rather 'hot' route for one, and for two I was simply unable to afford the extra gas money and possibility of breaking down at the time. Still, Elizabeth Lake Road west of Palmdale is a good little route, one that I drove many times on the way to a friend's house. My standard of measurement on that route - when it gets twisty, if you can go double the posted limit, you have something. If it went through without wrestling and drama, you REALLY had something.

This 'boat' is really something.

Believe it or not, there are people who would be
'embarrassed' to drive this. I feel the same way
hanging around such folk...

The biggest foe in handling is the stock 'baloneys', grandpa spec tires. I'd imagine perhaps the Goodyear cop tires are better in this regard but you have lots of weight, an old school suspension and floppy sidewalls. Doesn't inspire confidence.

However, all of this is easy to correct with bolt on parts, and it's incorrect to assume that stock equipment hindrances indicate a lack of tunability in the overall platform. If that were the case then the Honda Civic would be an 'eh, pretty good' handling car but with upgraded wheels and rubber the chassis really starts to come to life. The factory equipment was often tailored to a commute-friendly conveyance, but had great underpinnings. Why would a Buick be different?

Thankfully the stock Impala SS items and huge amount of parts that fit this chassis and GM full size cars going back decades make it very easy to get good handling out of the Behemoth. The SS wheels are huge (17x8.5"), the tires available fit everything from Porsches, BMWs Vettes, etc - you can easily get tires in this size with good life left on them used, because enthusiasts with more money are upgrading.

German Tyres!

Once you've got fat meats under the this car, and lower the mass some, the character changes and now you're driving a real Impala SS clone, aka the 'Four Door Corvette'. The Hotchkis springs are really low; I think perhaps stock SS springs might be a better daily driver setup, but they handled and rode great, and my issues were mostly with my cockamamie exhaust mods hitting, which with some real money spent on the mufflers wouldn't be an issue.

In any case, now the car was ready to really throw down.

In addition to the Hotchkis springs, ContiSport 2 tires in 245-45-17 size, stock Impala SS wheels (made by ROH), I put Energy Suspension end links on the front, wooden spacer mod in lieu of buying body mounts (worked! Lasted, too! Free!), modded the exhaust to add both tone and power (tried both Muffler Delete and straight pipes (but with cats/stock exhaust), the one pretty liveable, the latter just barely tolerable, but a hoot.

The intake was re-modified during my smog test prep to a simple straight piece of sewer pipe. No fuss, no muss, no tape!

To give the car a little more driveability and panache in the interior I put in a Grant 737 faux wood grain wheel. The polished center's finish is ultra scratchable - might be worth clear coating. I mean, brand new microfiber cloths scratched it.

Also, if you use any real tools in the cabin after installing this wheel, be very careful, or you'll end up with an annoying chip in your wheel like I did.

The wheel did match the faux wood grain of the stock interior decently, did tighten up the controls a bit by being a smaller than stock diameter wheel, had a nice fat grip to it which was nice while driving, better than the stock wheel. I got one because it was 40 bucks off Craigslist. I don't know why, but it might be because if I'd have paid the 140 that was the suggested retail I'd have been more than disappointed - I'd have been livid.

I also added an Auto Meter tach that went in with one 10 cent screw in a stock screw hole in the trim around the gauge pod. It blocks the coolant guage, but hey, while I was at it, an Ultralite temp guage was going to go next to it. But then...

I actually think this sums up the car's 'smack dab between
modern and classic' vibe, myself.

I'd ignored a leaking problem at the axle, and the bearing seized and wore the axle down. I started looking up the parts, but had very little cash month to month to live off of. Still needed a car to get around and didn't have off street parking, so it had to be moved at least twice a week.

I started considering my options, and while I'd certainly lived a car guy's wet dream - doubly so for a guy sleeping in the same car he's wrenching on, natch - I realized I'd missed other opportunities and ignored other parts of what I consider 'my work' messing with this thing.

I also realized that, sky being the limit - this car could be built for drag, autocross, road race, what have you. Six speed? It's happened. Totally doable. Parts are there.

But there was the problem. I needed something that couldn't become such a pit. I've dreamed of an LS7 in...well...anything, really, but made me think if I'd gotten, say, 30k for some reason, would 18 go to what I consider the most Gonzo stock motor from Chevy in modern times? Could, and then it could get crashed, stolen, impounded after I'd frittered away the rest of the money like a real fool.

And, as I've often said, I doubt that in decades to come I'm necessarily going to be pleased with myself if it turns out I'd ignored my artistic pursuits in giving into my obsession with the automobile.

However, I do think it was good therapy, did wonders for my self esteem - "Dude, NICE car!" was an everyday occurrence. Woke up behind Gold's Gym many a time to see people checking out my car, going "what kind of car IS it? A Roadmaster? Oh...it's a...Buick? Really?"

Really.

I don't have to tell you there were some funny/weird looks when they saw a guy sleeping in it. Makes me laugh thinking of it. However, I saw some of those guys get in some high dollar hardware after checking out my ride. Not like they were driving boring beige crapmobiles and didn't know a good car when they saw one. And I'll bet they could afford the dough to recreate one.

At the end of the day, it was a wash - another fan of the breed and real SS owner, Matt, stepped in and bought the car for 1200 bucks as-is, which gave me enough money to buy our next subject, a 1980 Mercedes 240D, get it registered, cleaned up, and kept the ball in play, so to speak. Without having built this car to it's then current aesthetic standard (Matt's since taken it further, will talk about next post), I doubt I'd have sold the car in stock condition for the 700 bucks I bought the Benz for. And I needed all of it to really continue rolling, so I can consider it an investment in the end result.

If I hadn't been a fool with my money, I wouldn't have had any money to take care of practical business...ain't that a bitch?

Matt's intention was to daily drive the Roadie and keep from putting excess miles on his SS, which is working - he now says he likes the SS better, at least in the 'cool car' sense!

That's as good of a compliment as I can ask for. You heard it here - after all that 'it's an SS in a business suit' talk, it's confirmed by a guy who has a really nice example of the target car.

You know what to do.

The new owner has been doing this car up right.

Final thoughts? The 94-96 Buick Roadmaster is a great car in it's own right, in stock form. It also happens to have the ability to be be all things to all people. Need loads of storage? 20 cubic foot trunk. Got kids, lots of friends? Seats six. Got toys? Tows 5500lbs. Love American style? This car is classic American automotive panache for the working man - as only we can do it. Love American V8 power? LT1 powerplant is 260hp and 330lb-ft worth of Small Block Chevy lover's dream factory 350, with a great exhaust note. Want it to handle? Give it Impala SS spec bolt on parts and it does. Efficiency? 15city, 23 highway, 18 combined. You'd be surprised at how many vehicles that can't do much of the above get that mileage - or worse.

The car has a huge, outsized personality - big roar from the exhaust when pushed, a cool burble when cruising. Big, flashy, lots of chrome, stainless, and machined finishes on the ROH wheels, which really are a cut above the usual aftermarket stuff. It all goes together like it was factory designed to do so - because it was.

If you never thought you could love a full sized, automatic transmission equipped American 'luxo barge' because you're too much of a 'cool driver car guy', you might want to think again. Just don't build one of these if you don't want everyone in the neighborhood - every bum, every old lady, geek, yuppie, gang member, OG, car guy, cop, kid, etc to tell you that you have a nice ride.

Because they will.

There are some who might say 'that's all well and good, but I'll bet, say, a late model Mini S Turbo would take the overweight pig out.'

Thank you, sir, because what's a performance build without a kill story? 

Heading out on Elizabeth Lake Road, or more appropriately, where it changes to that name from Palmdale Blvd, I was pulled up to the light up in front. A silver Mini S pulls up into the lane next to me. He checks the car out, which isn't anything new to me, so when the light turned green, I took off like a normal human being going somewhere, not a hyperactive kid out to prove something on a boring Friday night in the Antelope Valley. 

The kid hears a little note from the pipes and just jumps on the gas. I look over and he's BRRRRRRMMMMMMMMMMing by me, and I saw the S badge on the fender. 

"Good. I won't feel bad about this."

I hit the big chrome foot and all 5000 lbs of man, dog, car, and trunkload of crap take off like a bat out of hell. The 350 roars, a rarely heard but great sound. No worries, rolling start, nothing to hook up here, just pure power and gearing. Put the foot down and the 4L60E takes care of the rest. The Roadie's sole two specs that are off from those of the SS are no rear discs, and 2.93:1 gears instead of 3.08. The SS is a 15 second car in the quarter. The Mini S is right there, similar trap speed and elapsed time. 

Only, this LT1 has been breathed on just a bit. By my estimations enough mods have been done to facilitate roughly a 25hp increase over stock, to 285. 

This car should do low 15s or better with the mods I've done. Now, granted, it's not a Motor Trend style instrumented test, but it is a bogey. The Mini S is faster than most of it's four cylinder brethren. No worries about getting shown up by any average or better four banger in this big, bad Buick. 

I watched the guy try, hard, to keep up, but by the time we got to the bottleneck, his front bumper was barely ahead of my back bumper. He lifted (had to, I wasn't and another advantage of a fast but huge car - you don't get pushed around by much), and I looked down at the speedo. 108mph and I lifted, a whole mph away from hitting the factory limiter. 

Not bad - a sound drubbing even though frankly the race was already 'on' by the time I knew I was a member of it. 

Eat it, Chapman fans. And this car cost less to build than a ratted out, rattle canned, salvage title Civic or similar condition Miata. And while it's possible a Miata will get you laid, you're not getting laid in one. 

Admit it - you only got into little four bangers anyway because you thought you couldn't afford a car like this. Look back over my financial figures - this car was nothing if not cheap, even without the insurance windfall. 

Turns out the Big Three were putting out some good cars all along. They might certainly not be BMWs, but then, do they have to be? Do we all have the same tastes? Can you picture Billy Gibbons stepping out of a 328i? There's a certain thing about being American, and we get it best and do it best. This is an example of that, and the same DNA is in the Impala SS, a car I've seen enthusiasts import to Japan, import to Sweden and other places it was never sold - because they got nothin' like it. 

The Big Three had some gems. Maybe even they didn't know it - GM certainly bunted on what could have been the 90's equivalent of the GNX for Buick. But that's ok, that's why they're cheap and they get such a reaction - you're in on a secret. You don't have to buy a car made in America in the last ten years to get an American car that's solid, well built, reliable, decently economical, and a hoot to drive. 

As far as project cars go, this one was an unqualified success. As far as cars that I've built and owned go, this is my favorite. So far...

"Comin' to save the MOTHERFUCKIN' DAY, yeah!"

Project Buick Roadmaster, Part 7: Impala SS-ify Me!

Sorry for the wait. Not everyone has the option of being punctual whilst hot rodding the car they're sleeping in, and since the last post I've suffered the losses of my camera and laptop, and are only now finding a computer available to read my old memory card, etc. Thanks for waiting, all two of you.

There's a certain fear in hot rodding - the idea that you're going to buy Car X, mod it in various (and often expensive) ways, and for all of your effort, you're going to end up with what ends up being know as "Oh - THAT car."

Somehow, someone didn't see the local Cruise Night Crew guffawing at your 'Pintomino', no matter the rare 13" alloy wheels and other bits from the Mustang II bin. The car below? An examplar of taste compared to the 'Pinto-mino' my cousin ran around in while converting his 2.3l Mustang to the proper 5 liters. Missing? Oh, I don't know, the twin Cherry Bombs (complete with flappers) that were supposed to add a 'big rig' air to the little Pinto. No, it wasn't even a stick. I'll see if he'll send me some 'blackmail' photos later, but this isn't far away!

"Dude, it's all custom...it's gonna get me LAID, for SURE!!!"

Such was my personal nightmare; after being 're-dyed in the wool' as an Import Geek, I just wasn't capable of shutting the Bench Racer in my head up; "The chassis dates to 1958, it's not even a unibody, 4200lbs(!) of steel, no one but drag race guys seem to build them. You're going to end up with a medium fast in a straight line car with wheels that make it look like it should be faster that it is. Lame." Granted, I was more going for 'fastest RV I can afford to live out of', thus sheer capacity was more import than curb weight. But the nagging little small bore fanatic in me essentially voted for keeping it stock.

Yeah, right. Never seems to work out that way...

Basically, I'd been brow beaten to the effect that any car that didn't show 'Miata-ness' in it's stock configuration was simply beyond help, even though such luminous examples of import righteousness as the RX7, Supra, CRX and other Honda Si models, etc, rarely attain any kind of 'dominance' at the track unless modified in the first place. Don't bother sinking money into a pig, is the thought. And, of course, there's the "I got my info from [Blank] Performance Magazine" syndrome, where you'll rarely find worse information for the grassroots builder, even online. The schlubs online at least only have their own shortcomings to deal with - they're not actively trying to sell you automotive snake oil with inflated claims of power gains.

You know the one - "Yeah, this exhaust is worth 20hp on this car - granted, that was on a motor that had custom porting, custom ground cams, and oh yeah, it's turbocharged." Gains without said work? Take a guess, but I was warned by Mike Kojima himself online when I had my SE-R that the stock exhaust was fine up until ~180hp had been achieved - in other words, a more or less fully built NA motor or a Turbo version. Said 500 dollar cat back exhaust's actual worth to folks more interested in going fast than impressing 'net geeks they'll never meet? Almost nothing unless you've already exhausted pretty much every other modification.

So when I set out to modify the Roadie, I was skeptical. "Oh, this thing handles great now" never seemed to be backed up by skidpad tests and usually was uttered by a real Impala SS owner - in other words, guys with money to buy badges that match VIN numbers, not my game personally. Also, it tended to be uttered by folks more interested in quarter mile times than autocross dominance. "Handles great" to me sounded like it was coming from a guy who thought it was 'great' compared to the '65 Impala he used to have, or 'better than when I was driving to work on Big N Littles!'

However, I got my last big check in the mail, and the idea had been obsessing me to the point of idiocy anyway. I cashed the check, got online, and smashed headlong into a brick wall. Oops - no SS wheels for sale. Unlike last week, when I was checkless and three sets where going for ~350 bucks with tires.

To the forum! For some odd reason there was a set waaaaay out in Pomona that didn't show up in my search, but after posting a wanted ad over at http://www.impalassforum.com/, I ended up with a lead. I scored a good set of OE SS wheels, sans center caps, for 250.

Next I had to find tires, and turns out many forum members buy their 17" and up tires from as far away as Hawaii used a few exits down from where I stay. Atlantis Tire takes advantage of a local condition - that of having lots and lots of new BMWs and Porsches in the hands of owners that want to distinguish themselves from the 12 other BMW or Porsche owners currently bellied up to the bar at the Viper Room. Or wherever it is they hang out at. These are good sets of tires, inspected for flaws, for a decent price - 200 bucks for a set of Continental Conti-Sport CS2s in 245-45-17.

Around the corner to a local tire shop and I was in business! (For an extra 50 bucks.)

So, 500 bucks for a set of Impala SS wheels with Porsche tires. Not bad - all 'known quantities', no issues with fitment, bolt them on and go. I wasn't going to have such luck in the aftermarket. Besides which, though it's an 'obvious' mod, the ROH wheels that came stock on the SS are fairly iconic for a reason, are OE tough (nice when you're controlling two tons of steel driven by a lunatic), and are even easy to clean. They might not have the cache of other wheels, but think about it - transport yourself back to 93 and being, like a few folks, a little underwhelmed at the 'Shamu' styling of the Caprice. A little black paint, chopped police springs and these wheels later, you're standing in line, cash in hand.

Nice wheels.

My original plan was to get the rolling stock changed out for minimal cash. This involved selling the OE Buick wheels and tires for ~150 bucks, reducing my investment to 350 bucks. However, a forum member came out of the blue with an offer: "I've got a set of Hotchkis springs here with 8 miles on them. Wanna trade? Huh, huh?"

Let me look at the car with just the wheels on again...

Buick Roadmaster, now apparently with 4 wheel drive...

Dammit, man, you KNOW I wanna trade. Sigh...looks like I'm heading back to Peanut Butter Sandwich-ville faster than I thought...

A trip out to the desert to my secret underground garage facility and many knuck busting, ball joint splitting hours later...

Well, actually, two trips later. I spent the first trip out lowering just the front, which was less than ideal in a few ways - handling, one, and two, approaching driveways and dips, as the higher back end tipped the front even closer to the pavement.

After getting both ends on, we have this result...

Sweeeeeeeeet!!!

Not only is the stance pretty amazing, the handling is now up to par with my other modified vehicles of recent ownership. I'd regularly go after 35mph rated corners, and see how hard it was to double the posted limit. That was pretty hairy with the stock configuration as the 75 series sidewalls were just not cooperating. After the Hotchkis springs and SS wheels/Contisports went on, suddenly it just went through the corner. No drama, and we're talking a 4200lb car when it's got an empty trunk. I was running it with a quite full one. 

The results convinced me that with the SS wheels, good tires, and lowering springs (stock Impala SS items probably would be nearly as good with better ground clearance), the 'Grandpa' Buick is all of a sudden willing to play when the road gets twisty. I can now see why the SS's and other B bodies do so well in motor sports despite their gargantuan size. 

I think a mildly modded motor, SS wheels/tires, springs, shocks, and rear lower control arms are all this car really needs to get down. The potential was already evident even without 'appropriate' shocks (just used the stock items), not even an alignment. This is a good driver's car, and seeing SS's giving 'real' track hardware sweats at auto crosses doesn't seem weird to me at all anymore. 

Pimpest Ride on Skid Rose. Woo not included.

WARNING!!!!

Run these tires on a heavy car like this for a few months without taking care of the camber gain WILL result in having about an inch of steel belt looking at you from the inside edge of the tire. I pulled four different 1/4" shims out of the upper A arm mounts to put it 'eyeball' correct after seeing this, and it did mitigate the wear some, but still, message to the wise - if you LOWER a car, ALIGN it ASAP! Cheaper than a new (used) set of tires.

I never got to finish this piece before my laptop crashed last year, so this isn't the promised wrap-up, just finishing what was to be the last installment on the car while I still owned it. 

Stay tuned for the wrap up and the story on the 240D buildup that came after - aka the 'Easiest Hot Rod In The World'.

Small Engine, Big Efficiency? Why Bigger Can Be Better.

Small Engine, Big Efficiency? Why Bigger Can Be Better.

Or,

How to NOT waste your used car budget on something you'll hate.

As mentioned last post I've been crunching date looking to get the most out of my budget for my next car. While there are any number of tasty rides available for under 3k - I was looking about 6 months ago back when a lady was telling me she'd help me buy a 'cleaner' ride than my Benz Diesel, as she was apparently Compression Ignition Phobic - most of the truly cool ones are either too small (got a dog and crap, need space), too expensive to keep up, or too fuel thirsty. Some are all three.

Some, like the Family Truckster here, only come in
Metallic Pea.

BTW, real Craigslist find while on my search..

It started out years ago when I started looking for a 'fuel efficient midsize SUV'. I looked at various 4 cylinder models - Isuzu Troopers and the like - and came to a conclusion - mostly all a four offered at that level was less power than a six. While there were some fuel efficiency gains, we're still talking dismal mileage.

So how does one avoid having four cylinder passing power with eight cylinder mileage?

I've been using www.fueleconomy.gov extensively lately, and I can't recommend it enough for those of you buying a new or used car. Like a lot of people I hear 'four cylinder' and immediately think two things: 'low power' and '30mpg' or something along those lines. Sadly, though, there are a LOT of four cylinder cars and trucks out there that, depending on your driving style and whether you're mostly a city or highway driver, might not only be slower than your current ride, or the 'ride you want', but less efficient and economical as well. Not to mention, less capable...

For instance, last year I was getting a little bit of an 'enthusiast sales pitch' from a guy who likes the Toyota Previa minivans. They're pretty cool for what they are, bland styling for sure (I remember thinking of them as 'eggs on wheels' in junior high), but I was looking at something that would absolutely blend into modern traffic but be old enough to be cheap. Huge amount of room for music gear and/or living space. I saw a 2.2l Toyota four specified and thought it was a good match - it HAD to get better mileage than my 2 ton plus 5.7l V8 Buick, right?

Well, kinda. 

As you can see here, (http://fueleconomy.gov/feg/Find.do?action=sbs&id=11063&id=11404&id=27947&id=11432) the Previa gets 17 city mpg, 21 highway,  for a combined 18 mpg. 

The Roadie got 15mpg city, 23 highway, and 18 combined.

So if you had a 50/50 mix of highway and city driving the result is a wash. Go with what moves you - for me, that was 5.7 liters of roaring tailpipe music in a car that literally got me mistaken for a pimp - by a real pimp. 

If you're mostly driving in town, the Previa has a 2mpg edge, and if you're driving mostly highway, the same 2mpg edge goes to the Buick.

If I could easily swallow the monetary difference, the Previa looks outmatched by quite a bit. Would keep me from going bonkers thinking about engine swaps, though, because the Previa is pretty much foolproof in that regard - the factory that built it decided it was just easier to supercharge the stock motor. Makes a shadetree guy like me think of greener pastures...

You'd think a 5.7l, 260+hp American OHV V8 and a 2.2l DOHC Japanese I-4 would get wildly different results in the mileage department. I think it's best expressed as 'Overall Efficiency - Work Demanded = Actual Efficiency'. If the four didn't have to work so hard to move those 3500lbs of van, it would get better mileage. The V8 can lope around at lower rpm and do the same work in a relaxed manner. I don't doubt the LT1 would probably match or better the stock 2.2l powerplant if a swap were possible - after all, while the aerodynamics might suffer a bit, the Previa is 700lbs lighter too.

Reminds me of the old C5 Z06 vs BMW M3 reviews. I recall that the NA I-6 of the BMW put out less torque at peak than the LS6 did - at idle. Remember, torque = work, and out of horsepower or torque, the latter is the only one directly measured, rather than extrapolated by a formula (torque x RPM/5252 = HP). The less you have available, the higher the motor has to spin, and the more fuel consumed. 

Pictured: Efficiency. No, seriously...stop laughing!

It's a path to fast, and a path to efficient, apparently. Comparing more apples to apples motors, in a way, I recently got into a bit of a spat on YouTube with a Lexus fan dissing GM cars. Looking up the LFA specs, I noted that not only does the 3300lb, 550hp V10 'supercar' barely beat the ZL1 Camaro around the Nordschlieffe by 3 seconds over 13 miles, the 6.2l, Supercharged, 638hp LS9 in the ZR1 get's better mileage than the 550hp 4.8l Lexus V10. Not by a few, either - a base 6.2l Vette will turn in city mpg similar to the LFA's hwy mpg. 

Overall, the 'huge' engines, 6.2l, 7.0l, and 6.2SC, all turned in better mileage by about 5mpg average. 

(Vette Lineup VS Lexus LFA MPGs here - http://www.fueleconomy.gov/feg/Find.do?action=sbs&id=31326&id=31328&id=31327&id=31089. Left to Right - 'Base' Vette, Z06, ZR1, LFA)

Not bad considering the ZR1 is a third of the price of the 'base' LFA. Not a bad comparision, either, as both cars are obviously designed with high performance in mind and have similar curb weights. Drag coefficients are as follows: 'Base' Vette, 0.28, Z06 0.34, ZR1 0.36, and LFA 0.31. Even the 'porky' Camaro ZL1's average MPG is 16 - which is the LFA's highway rating. That's with a .35 cD and an extra 700 lbs or so to push around. (http://fueleconomy.gov/feg/Find.do?action=sbs&id=32161&id=31089)

Looks like a lot of engineering misapplied in a vain attempt to give a 'halo' effect to a bland product line. Or an example of how low end torque can be used for work, play, AND efficiency - but that's no news to diesel heads. 

Pictured: $375k worth of slower than a Vette and less
MPG than a Supercharged 6.2l Camaro.

Also pictured - why 'Hot Rod Black' should only applied to,
you know, hot rods.

But it also illustrates that, down here in the real world, not everything is cut and dried as it seems. 'Smaller motor = more efficiency' doesn't always compute. Not that one should just as blindly buy any old V8 engine and assume it'll be efficient for your particular use, either. 

So, for instance, if I were to truly put down roots here in Venice and want to stay, a Previa makes slightly better sense - who gets to cruise in overdrive in LA during anything but the wee morning hours? Almost entirely used in the city, over 10k miles, the Buick would consume 666 gallons (hee!) and the Previa only 588, a difference of 78 gallons and 351 dollars in a typical owner's year. That's about 30 bucks a month. Of course the same 2mpg difference in an all highway scenario would be the same, and for someone who could care less about the 30 bucks a month, well, I've got plenty of blog space devoted to the big B body. 

But, as I'm planning on going to New Orleans soon and have 2000 miles or so of highway driving, a Roadie would actually save me gas money, as well as being the cooler ride. When I lived in the Desert and you'd be in overdrive by the time you passed your neighbor's house, there would be no question - more power AND more MPG, please, all in a ride fit for a prince - or, at least, a pimp from Pomona...

Ok, so mine wasn't Magenta. Otherwise, I was a little embarrassed...

Oh, and I don't do decals, so NYAAH.

Comparisons like this illustrate the finer details of choosing a ride, especially on a pretty limited budget. I, personally, wouldn't want to pay more or the same amount to get less of what I want out of my purchase. 

So at the time I also compared the Chevy Astro 2wd passenger van, a solid workhorse that's become practically legion as you literally see them all the time in LA. And I considered another Mercedes 300D Turbo in a pursuit of efficiency. Both were being weighed against the Previa and Roadmaster.

The Astro, despite a similar curb weight, almost identical transmission, and a 4.3l V6, gets worse mileage than the Buick. Without going into all the other reasons, this shit-canned the Astro pretty quickly in my eyes, though I'd consider one as a secondary vehicle. To be fair, the parts availability of the Astro is great (it's all S10/G Body parts and other standard GM RWD stuff), the Previa will never take to engine swaps, and Toyota's solution to having adequate power in a Previa, the S/C supercharged model, turns in similar MPG to an Astro. The Astro, however, would take to any number of engine swaps in search of more power or economy.

FWIW, the differences between the 4.3l V6 Astro, especially in MPFI trim (190hp, 260lb-ft), and the Previa LE S/C (160hp, 200lb-ft), considering the 1mpg difference city/hwy, are pretty much obvious. A low production high tech engine that was only made for one generation (plus the funky configuration, accessory drive, etc) vs. a 6 cylinder version of the venerated SBC in production for two decades -  are semi negligible - until one gets to the tow rating. The Astro? 5500lbs, same as the Roadie. The Previa? 3600lbs. If you want to tow, you know where to look. If goofy, one-time only arrangements and 'mid engine' minivans are your thing, well, best of luck with that. 

The Mercedes W123 body 300D was an interesting story as it's a 21mpg city, 23hwy, 22 combined car. So I'd gain quite a bit in town - more than most cars in the price segment that aren't 4 cylinder compacts with sub 2.0l engines - but no more highway mpg than my Buick. The city mpg was where I wasn't happy, and in that regard the 300D had better 'city manners', such as parking (GREAT turn radius/steering angle) and creamed the Big Bad Buford by 6mpg in the city. But... 

Then the gear head came into play.

"You know, the LT1 in the Buick's already been breathed on a bit, should be 285hp or more, probably stockish 330lb ft. The OM617a in the 300D has a mere 123hp and 170lb-ft, and while it can make more, it's a 2500 dollar Myna pump and a serious turbo upgrade away from any impressive numbers..."

Plus, yeah, I'm trading THIS for a Previa? Riiiight.....

That sealed it. I kept the Buick for another year after this initial run down. I still kind of regret selling it, to be honest - the car was a bonafide G-ride, and even a local character - an Inuit orphan who we all know as 'Pirate Darren' due to his ever-present leather Tri-Corner Hat, aka one of the least 'gangster' people I know - called my ride 'Gangster As Fuck'. Hard to show up a few days later in a car that looks like I knocked up a broad after hearing that a few dozen times...

So I kept the Buick for another year. I don't regret it, in a car guy way, in a 'practical guy' way I kinda do though. Really, the better option than both was the 300D and it's probably going to be my next ride, as these Benz built-to-a-standard-not-a-price-point tanks are still, in my opinion, the automotive deal of the century, and the 300D's average mpg is Accord/Altima like (http://fueleconomy.gov/feg/Find.do?action=sbs&id=27947&id=11108&id=11827), but I don't have to drive a frumpy mid 90's midsize FWD sedan. Granted, they're faster, and rated at better mpgs highway. But the 300D also has been reported reliably to get upper 20s highway if you're not driving 80 the whole way, too. 

Something to be said about getting into a Benz for the same price as an Accord and getting similar affordability and efficiency. Not to mention, this:

Choose wisely.

We're Back, And Twice As Annoying

Sadly, this was the last view I had...Now I know how the
driver in the other lane often felt.

Hello all,

Sorry for the delay but I was sans laptop for a good long time there, and while I could get my business done online via other computers, doing the whole thing was a bit much so I had to back-burner it.

Things have changed quite a bit. I'm no longer rocking the Roadmaster, having sold it for a small profit and moved onto an even bigger project, another Mercedes 240D manual trans. I'll do a wrap-up on the B-body soon and even see if I can dredge up the new owner's email for some updates.

I'm in an interesting space, waiting for the California Voluntary Advanced Vehicle Retirement program to get back to me. The 240D is quite beat - I tried to 'rescue' it from it's former life as an LA desert Mexican high-schooler's lowrider project, and kind of succeeded. I might be jinxing myself but I just think I picked a bad one this time and, considering that the state will give me 1500 bucks to junk it, I'd be better off getting something else with the proceeds rather than sink more of my limited funds into it.

I'm wading through Used Car Buying Circa 2012, seeing what's changed and what hasn't. I'm still 'urban camping' in my vehicle at the moment, so I can't go too gonzo on my next ride looking for G force induced thrills. But there are some pretty decent choices available in LA for 1500 bones and it's been interesting going through the elimination process to see what I'll end up with. Looking to see what I can get for the money, I've been investigating everything from cop cars (GM and Ford), small wagons, trucks, diesels, F-bodies and Supercharged Buicks.

So the Roadie all-rounder wasn't to be, and now I have a rat rodded 240D as my mobile palace/whip. More to come on that, the State of the Used Car Address, a wrap up on Grandpa's Revenge/Project Pig-Sticker and an introduction to Project Dead Meat, aka the doomed 240D. Stay tuned.
