Thread: Whipple set up?

I'm planning on a cryo-treated Muncie 282, which I've seen used with 500hp v8's without issue, i will just have to avoid wrinkle walls.
And as far as selecting a blower, with enough work a whipple can run crazy high numbers, but the 140 is oversize, which is why i was entertaining the idea of running a 100. I will have to look up more about TVS set ups, so far i understand that it is still a roots style blower, but a more efficient design running 4 vain rotors instead of 3. And i can't run a centrifugal i don't have room to mount it or an intercooler. And just to clarify I'm not afraid of fabricating or engineering an adapter plate, and i will be running a n* throttle body

MUAHHAHAH seriously? What v8 have you seen run low 11s with one? None, because it didnt happen.

What do you have against bias ply slicks? They are by far the safest option in a fiero.

a 140 is abou the right size. Going smaller would just be a pain and not save you any money, and kill any potential resale.

For the money, the whipple may be better, although the TVS would be easier to install by a large margin.

And i can't run a centrifugal i don't have room to mount it or an intercooler.

You need to intercool the whipple..... Its a flat requirement due to the way it works.

And just to clarify I'm not afraid of fabricating or engineering an adapter plate, and i will be running a n* throttle body

Its more than just a plate... Its an intercooler, a blower inlet tube, and INTERCOOLED bypass system, 8 rib belt setup.... all in one small space. Its possible just far from being easy.

Ok let's go through this again, thanks to the nay sayer

There are many people using the muncie 282 in their high HP Fieros including cammed ls1's making around 500hp, if that doesn't hold i will upgrade to a f40 form a G6.

My problem with bias ply slicks will add a lot more strain to the transmission and axles, where decently sticky street tires should allow for enough slip to avoid transmission failure.

The reason i'm saying a 100ax vs the 140 is because it is closer to the displacement of the original supercharger but it is much more efficient which would leave me to believe that it would be a better match for the 3800, so that was what my origional question was about it has nothing to do with money or someones opinion.

You are correct the whipple does seam to be putting out better numbers and more proven results compared to the tvs

I don't have room for an air to air intercooler, I'm not talking to under the supercharger

Yes i'm aware that it's more than just an adapter plate, but it's not really that complicated either, just a matter of alinging the supercharger properly finding an inlet tube that will function properly which won't be very difficult for my set up, the only thing that will be difficult is installing a bypass valve but i'm sure i can figure it out without too much difficulty. 8 rib i can get from zzp. It won't be easy but it won't be hard.

I'm not dead set on a Whipple, but i just haven't seen the numbers I'm looking for out of other chargers, or at least ones i can run. But if anyone has links to a build with high numbers let me know.

That's what my car has right now, 5spd, ported blower, ported LIM,3.5 pulley, i haven't taken it town the stip yet but as is right now, my 0-60 is just under 5 sec. with a good launch. I'm going to be doing a major rebuild on the car soon, I want to build my engine while it's out and start preparing to the new blower.

No. Just no. The F40 is a pile of crap, and a downgrade from a 282. I have a stack of 3 282's in the garage from a measly 600hp fiero that ate through them behind a very conservitive and experienced driver. The cases fall apart, the gears fall apart, the syncros SUCK, the diff bearings twist...the spiders in the diff are tiny.. Its garbage dont kid yourself that it isnt.

wrong wrong wrong. Bias ply tires will give you a shock absorber to the ground and ELIMINATE wheel hop... The only 2 things that will ruin your day (although you will break an axle before you break the trans).

So you want to upgrade the blower so you can not upgrade the power potential. Good plan bro.

I don't have room for an air to air intercooler, I'm not talking to under the supercharger

Who said you needed an air/air? I have air/water coolers in all of my turbo fieros (and even my turbo honda)

Yes i'm aware that it's more than just an adapter plate, but it's not really that complicated either, just a matter of alinging the supercharger properly finding an inlet tube that will function properly which won't be very difficult for my set up, the only thing that will be difficult is installing a bypass valve but i'm sure i can figure it out without too much difficulty. 8 rib i can get from zzp.

Considering I have done it before... trust me its hard. You dont "find" an inlet that works because everything out there is RWD, and you dont just bolt a proper bypass valve in.

I'm not dead set on a Whipple, but i just haven't seen the numbers I'm looking for out of other chargers, or at least ones i can run. But if anyone has links to a build with high numbers let me know.

Turbo is the obvious option as it works a billion times better... is a solid $4000+ cheaper, makes more power and torque across the board, and is easier to install. It is also more consistant and less prone to failures due to the fact that it is significantly simpler than a whipple install. The average mail order or random dyno shop tuner is going to be able to get better consistancy tuning wise from a turbo setup as well, due to the tighter cam setup you can run.

Sorry i just hate that guy, god forbid you want to do anything different, or original. He does this kind of thing on all his posts. Like the post on e85, just put in 30% larger injectors and drop your pulley size and you'll be fine where the guy wanted to have it tuned on e85 like he should, it's just stupid.

lol. The way I see it is is that its your car, do what makes you happy. I prefer positive displacement blowers too. Different strokes I suppose.

In all fairness though I do have to say I agree with some things he said. Minus the turbos being a billion times better. Maybe a bakers dozen.

Best of luck in your endeavors.

Thanks guys i'll just have to ignore him from now on, I was just trying to figure out if anyone had used the 100ax before, it is a fairly new charger, i'll have to call whipple one of these days, they should know which one would be a better option, and i will look into the tvs charger's but i haven't found one outside of a kit for another car.
