It is physically, impossible to hold ambient at boost. there isnt a compressor on the planet that can do that.

It is physics 101 "Boyles Gas Law".

Increase in boost. causes an increase in temps. Yes, an intercooler cools it. But unless you are running an ice box, then its not gonna happen.

Yes, there are many many many races that actually run 30-50* BELOW ambient. How do they do this? When they make the pass, they are running off of ICE WATER. Ive seen top mount 1800hp blown mustangs run 45* IAT's.. But they are also running about 5 gallons of dry ice and water. After the run, they drain it, and do it all over again. But on a closed system, utilizing a typical supercharger cooling system, the temps will stabilize, and run as hot as the blower is efficient enough to let it run.

Now I know Whipple is gonna jump back, and make claims that I am only saying this due to KB. Im not.. I am not saying the Whipple is hotter by any means. I am not referring to anything regarding what they "Cant" do. I am discussing IAT's in general.
I have never seen where it is installed.

Personally, I think if the IAT was placed in/around the lower manifold, like the other systems, it will run just about the same temps as any of the other very good systems on the market. I dont think it is worse than any of them at all. I have heard they run a larger intercooler under the blower. If that is the case, then it may very well have better temps, by a couple of degrees. But then you have to factor in the efficiency of the head unit.

Point being, is they will all be within a few degrees of each other. Nowhere near enough to determine one is better than the other due to IAT's.
