Whipple/Hellion Compound Setup

[SpartanDiesel]

Curious to see if there are any 5.0 cars out there who have (or more likely, have planned on/looked into) doing a compound boost setup, or know anyone who has?

Car currently has a Whipple/FRPP kit, 2.9L upgrade from Lethal. 47Lb injectors, with 75Lb sitting in the box waiting on someone to release a good fuel system.

It runs great, but have a deposit on its way to Michael at L&M for a built longblock, and am certainly looking for more. Doesn't seem to be than anything larger than the 2.9L is available for now (not interested in KB or centrifugal)- and with our goal being 1000 to the tire for this car, a compound setup seems to be the only solution for the kind of air needed.

The guys at Hellion seemed to think that the compound setup should work out well- as I LOVE the torque of the PD blower and aren't willing to part with it to go with a turbo exclusively.

Just hoping to find some insight from someone with some experience with this, with a 5.0 or 5.4L.

somehow i knew this question would originate from NC. NC has the most "i dont have enough HP" people ive ever seen. FL is a close second. GL with answer. Fayetteville chiming in.

Didn't know there has ever been "enough". Bigfoot will be found first:-D

I'd be willing to bet no one has done it yet.. it would be straight insane please do it

I believe that you can't run a T/S with a compound boost setup.. Hense my the 04 cobra guys don't or can't run a T/S with TT's.. You're best best is going to be TT's with no blower.

Man I spoke to at Hellion seemed to think it was entirely plausible. They have a setup to compound on the GT500's, and to the best of my knowledge the stock chargers on those cars are twin screws.

There are a few running kb's and whipples with turbos..

GT500s have eaton roots M122, no twin screw. you can compound with a TS but everything i've heard says that it just works better with a roots s'charger. i believe it's the different ways that air is compressed, a TS compressing the air between the rotors and a roots blowing air into the intake manifold, causing it to be pressurized in there.
it can be done with a TS however, as ford GTs have a TS stock and there are a handful of them running compound with great numbers. i believe throwing a TVS on there would work better though.
if your serious about this make sure you do a LOT of reading on compound boost(diesel forums are a great place to start). remember, it's not as simple as adding the turbo PSI and the blower PSI together, it ends up being a far higher number than that, lol. also, the supercharger will be a restriction, you'll be able to make more HP at the same PSI with just the twins.

Thanks for the info on the TVS chargers.

Do have quite a bit of experience with compound setups on diesels, hence the appeal to me to do it on the car. I do Powerstroke tuning for a living.

yeah, texas is pretty bad. tons of rich kids with alot of long open roads with few cops. that combo makes a potent mix of high HP cars haha

I would love to see it. Since you already have the blower it's the obvious choice. If you didn't have the blower I'd say you should at least look into a compound twin turbo setup. If you do this PLEASE post a build thread. There's absolutely no reason this shouldn't work. You've already talked to Hellion....give Lethal a call since they're the whipple experts and ask them what they think.

true. id say 85% of the termi's i see for sale are from NC, TX, or FL.

nice! i saw the name and it had me wondering but i didn't want to jump to any conclusions. you have quite the rep in the diesel world! have you tuned any powerstrokes with the empire diesel compound supercharger setups? that's a pretty sick setup they have!

Just seen a Shelby gt500 on 5.0 magazine thats running whipple and turbo, but I thinks int strip only not street.

Haven't done a set of Empire's turbos, but several of Elite's setup and one of Dirty Diesel's. We are waiting on a set of their billet 6.4L cylinder heads for our race truck. Seem like really nice parts.

Well, my general question of "is it possible" seems to have been answered with a yes.

Once the L&M engine is installed I'm fairly certain this is the route I'll go with the car. Something is just very appealing about a turbo'ed whipple car
