Where are the 4.0L whipple owners? Anyone care to share their data? Track times? Dynos?


I am considering using one for an LSx/4l80 swapped '49 5 window Chevy. Daily driver to boot.

 

WRP is probably the most knowledgeable on this one. He has a 4.0L Whipple on a 408....MONSTER combo at that! Check out his build thread and that might give you a little insight. On another note, any more progress on the T/A?

 

Not much to do to the TA without an engine.

 

WRP's car is a monster for sure. Does anyone have info on front feed 4.0L whipples? I've searched my *** off.

Only place I've seen in mentioned on the internets is Camaro 5 and a few early pics of the COPO camaros. Did the 4.0 blower on the COPO actually get the front feed or does it have that retarded (no offense to anyone that owns one) elbow that restricts the crap out of it?

 

From what I have read the 4.0 whipple on the Copo is a rear mount, and the 2.9 is a front mount.

I've also heard whipple will be coming out with a 4.5 with a front mount designed for the new camaros but depending on what front drive accesories you use it would work just fine.

 

Rumor has it they are coming out with a 4.0 front inlet designed for 03-07 trucks.

How true that is I do not know.

You might be better off just contacting whipple directly but there customer service isn't the best.

Whatever happens, be sure to post up and let us know. I would be interested in the outcome.

 

If they come out with one designed for 03-07 trucks that would be perfect. I'll do some digging when I get a chance next week and post up if find anything out.

 

Phone confirmed- they are developing a front feed for the trucks and said it's going to be a few months yet.

Also mentioned a 4.4 front feed for 5 Gen camaros but it's only available to the gear heads at GM right now.

They had me email one of their people about what I would need for my '49 so I'll keep you all posted.

 

We are going to be dyno testing the 2.9L on an RHS based 427 soon Bill. We will use it or the Magnuson on our 1000HP package. I wanted to get the 4.0L, well maybe next time. I didn't have much luck looking for info on the web either.

 

I just need to come apprentice with you guys Todd. haha You guys do all the cool sh*t that I think about doing instead of sleeping.

 

Latest I saw on this is the 03-07 front feed/intercooled deal will be coming in the next 30 days. Not sure how old that info was. Sounds to me like it'll prob shortly after SEMA.

 

a 4.5 whipple..... OMG

 

We are going to try to put together a 4.0L for testing, but the only real application we are shooting for is early model cars that have the room for such things.

 

Should be awesome. looks like the 4.5 is supposed to be a hair shorter but I imagine it's taller. Can't wait to see what you guys do with one.

 

Any updates?

 

yes, zero miles 2013 ZL1 with an RHS 427 and a whipple 4.0

 

Wow thing will be insane!

 

Needs a bigger blower !!

 

i was gonna slap twin turbos in rear not kidding

 

I did run the 2.9 with a 427ci engine and LS3 heads. It made 960hp at the flywheel and made 750ft lbs at 3000 rpm, all just under 15psi.
