Thread: 1999 GTP with Whipple W140AX - 537 WHP

Well yeah...that is because the Whipple is huge in comparison to the Eaton. And it isn't in its efficiency range until it hits higher boost levels...

the m112 eaton is 1840cc of displacment and you can get 2200cc of displacement whipple. not nesecerly a huge diffrence. but thats now why its more effecent up top. its the deseign of the blower is what makes the diffrence. an eaton simple pushes air and starts to become hot and unefficent in high boost aplications 15psi or so. at that about its about 50% effective. but the whipple actually compresses the air in the supercharger housing and puts out a more efficent and actually cooler air charge thus putting its efficentcy range in the 65 % area. its more than it being just a bigger blower. eaton could make a blower just as big and it would not be as efficent or produce the same hp numbers at high boost levels. but with that being said, if your not going to spin the whipple hard, 20psi range, then there is not much of a point to put it on because an eaton can keep up at lower boost levels.

for a centrifical. they can make boost from idle but it being a turbo design it builds boost with rpms. the higher you rev it, the harder it spins and the more boost they produce.

I wasn't talking about Cobra's...the Eaton GenIII M90 from the GP is tiny...the Whipple is more than just 400cc larger...this is a GP forum I could care less about comparing the MP112 (which is WAY bigger than the GenIII or GenV M90)...I talked to Paul at PRJ about it and unless you really have about 10 grand to throw at it...don't even bother.

here is some facts from the whipple website

Whipple Industries

whether it is mustang or grandprix, its still the same concept with some diffrence. still the same bottom line.

i never said go for it. i was just explaning the effects of the whipple itself.

really, it would be awesome to hear from the guy that has one on his car. i would like to hear what it takes to get it done myself.

Too much work.

Custom IC, Built bottom end, head work...lots of flowing capabilities...and a bigger pulley. Hell IIRC when Paul did the AnimuL setup on his car for the first time with no intercooler he ran a 4.2" or 4.0" pulley only pushing around 17psi or less...and still clocked a 13.3 in the quarter with a custom tune and dropped catback and open cone...

hummm. big cam build might be easier.

For $3,000+ for just the supercharger and adapting hardware to make it work...

Your damned right.

damn.


yea no. ill just spray the eaton

Hair Dryers are way better than an Eaton

leafblowers work the best.

I posted the link before of his build progress. Basically no expense spared and everything is completely custom.

doh, missed that. there is also a member that post here, robo something, cant remember his name that has a whipple set up. its intresting to see how diffrent people go about things.

Yeah, Robotech, i think his name is troy but not sure. He was in an episode of pinks and i think ran in the range of 12sec. Not sure if his car is running or not though now, I think he is waiting for a few fab parts from Paul too.

yea it ran 12.0 in 100* heat he said and DA close to 4500. at sealevel and in the 40* range i could see low 11's out of it i would think.

He is waiting on a custom IC right now so it isn't running as of date last I heard. But A LOT of his stuff was custom too...I'll try and dig up the emails tonight from me and Paul's convo about what it took exactly to run it...
