SUPERCHARGER!

Not done yet, but getting closer.

That's a hugh bitch! Did you fab the intake manifold?

Damn, that shit is TALL

[grandprix34]

haha, eat it fuckers! lol

Well, im barely taking off. What are you using for fuel needs?

[Fierobsessed]

yep, custom fabbed intake, really heavy duty, mostly constructed of 1/2" and 1/4" thick plate aluminum. Its only tack welded as of yet. Fuel managment will either be handled by a 1227727 computer with a modified TGP program, or a Turbo Trans AM computer, since they are so simple and so well documented. If I were to do it again I would have used the Ford's M90 charger, it would have actually fit between the cam towers, where to put the fuel injectors would have become the problem then. I opted for the 3800 style blower due to it being externally bolted down, not to mension a heck of alot cheeper! 150$ and its in flawless shape. I just got a brand new 96-97 Crate 3.4 DOHC today and will use that for the real deal. That picture is of a bare block with the externals loosley bolted on. Right now Im looking to find GM660 3.4 pistons with a 10-13CC dish to get me to that magical 8.2-8.5:1 range. Possibly thinking of using Camaro/RWD 3.4 pistons, they might be perfect. Now if I could get those in forged, I would! Tomarrow I'll slap the blower on the crate engine and take another picture to spread around.

[Lyle's GTP]

Did you just make the upper intake to bolt onto the stock lower? Or did you fab the upper and lower as one piece? It's hard to tell by your pics.

try CP pistons, they make all sorts of custom pistons, give them the specs you need and they should be able to do it fairly cheap, and everyone I've spoken to said they are exelecent and I too say they are perfect, typically they are used in the turbo/supercharged motors, I know I use them in my 1980 Mustang 2.3 Turbo, and they stood up to 30lbs of unintercooled boost. (runnin' 110 octane leaded fuel)

The last episode of "Rides" (which I have taped, lol) had a guy with a '33 Ford Sedan that he was restoring and installing a N* (Northstar for the mentally challenged, lol) that they are putting headers and a S/C on. They had to custom fab the headers and the intake, which was pretted bad assed to watch, considering most of us here would like to undertake the same kind of project.

I would still rather have the Quadra Deuce made by Rad Rides by Troy, lol. Who wouldn't love the old ZZ Top style hot rod with all wheel drive and 600+ horses?

for most stock replacement pistons, the RWD ones will have a HIGHER compression than the FWD ones. My friend bought some 3.4 Camaro pistons to use, and when comparing them ot the stock 3400 pistons, the 3400 has a deeper dish, so the camaro pistons will RAISE the compression.

This is going by stock replacement pistons bought online at PartsAmerica.com

[patgizz]

deeper dish = less compression

taller dome = more compression

Some going to flame, but I don't see how a M90 is really worth the effort of messing with. I've gotten sick results with my turbo rig (it's a kit too). The turbo Alero is doing really good too (that one's homegrown). All those dumb comments such as but not limited to turbos lag, and they get hot, and our cars don't like them can just not bother, I've heard it, it's not true, so stifle. I will admit that once the GA gets cams that the roots blower will have more torque under 3500 RPM, but until then it just doesn't compare.

The cam in the 3400 just seems to love the turbo. And yes, I do have dynos, and real people have been in the car, so on and so forth.

[Dave]

Phantom - can ya send me some info on yer turbo kit, and a copy of some of the dyno's? I'm not lookin' to flame, I'm seriously interested in puttin' a charger in my Z...

Depends on what type of powerband you want. There are M90 L67's running in the 4-500hp range that have a snappier throttle and more low end then any turbo could hope for.

A M90 on a LQ1 would be plain out sick. Got to make it my next project....:P

[Anonymous]

I agree and disagree. Any f/i will make a LQ1 simply haul ass. But I think a turbo is better. A blower or SC makes power all through the range. But at 7000 rpm it is making way more boost than at 3000. We will only want like 5-8lbs, especially on a stock motor. So figure 8 psi. Now if we have 8psi at 7k, than what is it below 2k? It iwll be low, probly around 1-2psi. Which is good, any boost is good, but the blower will give similar results as a turbo, just with a slightly better low end and a slightly worse high end. I'd go turbo, but that also is not good for autos as they rely on low end to get good 1/4mi times

[Dave]

that's not exactly true, you have to remember, as RPM increases, so does the requirement for air, meaning, more RPM = more CFM, so boost doesn't go up too much in the higher RPM bands as one may thing, my friends k1500 with a whipple charger on it, hits 6psi from the moment you step on it, till it hits redline.

a turbocharger on the other hand requires a certain CFM to generate enough spin to create boost, thus boost lag.

if you look at supercharger vs. turbocharger, remember that a supercharger will effect the crankshaft balance, as it's pulling power from one side of the crank, and it's a "flawed" power, meaning it's belt driven and never 0 balance and it's naturally pulling on the crank in a static position anyhow, so you lose engine longevity anyhow, but with a turbocharger the backpressure from the turbo itself (between the cylinder and the turbine itself) will burn exhaust valves, so either one can hurt the motor, even though it's making more power.
