I thought of KB, since that fits under the hood, but KB has a VERY bad track record as far as inlet temps go, they are extremely unefficient, and if you look through camaro5 you will find data from some of the well known vendors. Even with their LC (liquid cooled) blowers, unfortunately.

Try riding in a stock Camaro with the rear hood seal removed. The heat blast and engine fumes from the HVAC vents will quickly change any thoughts on modifying the cowl. A bigger more powerfull supercharged engine with more heat would magnify the problem. It will be like riding in an oven.

Works for the COPO, because of no HVAC or wipers. The procharger idea will look pretty good soon.
so what are all the street camaros with cowl hoods doing? The cowl hoods should release quite some heat at the back as well. Also, even if we are forced to cut the rubber seal right where the blower comes close to the firewall, we could it intact elsewhere, it doesnt have to come off completely.

Run an alternate fuel cell for the race gas, and pump gas tune for regular driving. It will be a lot simpler if you do something like that. The hot air that a procharger pulls in still results in lower IATs than a maxed roots type.

That is an uneducated comment. No offense. But really. A centri through a front mount will have cooler IAT's than that whipple 4.0.

Don't look at the intake location as a Downfall for the procharger. Iats Are only 10-15 degrees above Ambient. Roots type blower can do that, but not under boost or even spinning the hell out of it like you will be.

I'd be putting an f1 or f2 procharger or vortech ysi before I'd go whipple.

Don't know why anyone would release heat at the back of the hood. That is where the HVAC inlet is. How hot would you like the interior of the car to get?

The old cowl inductions for street cars like a '70 Chevelle were to let air in the engine intake, but they still sealed off the back of the hood. Race cars open up the back of the cowl, but they have no HVAC inlet.

There is a reason the ZL1 has the hood opening up front, and the back is sealed.

The new "Showstopper" hood has significant clearance over a stock hood. The heat distortion temp (HDT) of our resin is fairly high and more than adequate for any temps in the US but we could build a hood for you with an even higher HDT

Here is a link to the "Showstopper" hood,

Drove it in the summer, in 100+ degree heat w/o any problems and a 1000+ hp engine. And only on the hottest days do I even have to run the AC so I guess I am just lucky. Actually my stock 2012 corvette interior gets hotter than my Camaro does and it's hood is completely sealed.

I dont know what you know about Whipples, FYI the 4.0 has the ability to flow 2500CFM+ which is how much an F2 Procharger will flow, so I will actually be on the low side of the compressor efficiency while im on pump gas.

are you talking about inlet temps while cruising around or inlet temps at WOT? and do you have proof to backup your statement?

Im asking because ive owned almost everything, centri Z06, TT Z06, ZR1, TVS2300 427 truck, Whipple 2.9 camaro.

I also have all the options for me to choose from and I choose the 4.0
