Whipple Version 4.0, pics!






Brief setup is an RHS 427, Mast 305 LS7, Whipple 4.0, Custom dual throttlebody inlet, dual throttlebody controller, HPTuners 2.5bar SD OS.
Made 984rwhp at 6200rpms where we ran into a throttlebody controller issue, this was on 93 octane pump gas (no meth) 11.0:1 AFR and 16degrees of timing. Should make 1000rwhp on pump and we have a meth system just incase

Also, I know nothing about Ethanol, we dont have anything other than good old 93 octane gas at the pump and race fuel at race shops obviously (here in Dubai)
Just got it all working on my ctsv. Might be a option for you.
E85 here is like 76% ethanol or higher depending on what time of year it is. E85 = same as C16 but e85 is $3 gal or lower vs. $13gal
We arent spinning it at max rpm but the way it is right now its spinning faster than the COPO camaros if im not mistaken.
I cant imagine what this 4.0 could do with race gas at max blower speed.
Awesome attention to detail, love the hard lines
