The colder the outside air temperature air density increases so volume increases and greater HP gains.
The hotter the ouside air temp density decreases and less HP gains. Radiated heat from the engine compartment has to play aprt in this also. The tube have to stay at least the same as the inlet air From what I gather most of the testing has been done in California and I have not seen a lot of data. I would like to see some dyno testing here in Florida. Then some road testing on the highway and see what the cai inlet temps are and temps after mass flow meter especially when your sucking in road temps that get to 120degf. A 30deg swing in ambient temp can really effect the out come. I know that I may be nit picking but I truly believe that HP gains are going to be erratic from one part of the country to the other. 1 don't have a clue as to what that would be but I would guess that it could be as much as a 5HP spread.

What is does air temp at the throttle body need to be to produce 18 hp gains consistantly?

Let me kown if I am on the wrong track with any thing or has my engineering been getting in the way and just old nit picking. Working on Jet engines we were always trying to squeeze the most thrust at any conditions. Wether it was at sea level or altitude.

Considering this is a thread for an exhaust, ya I'd say you are on the "wrong track". :gtfo2:

I drove into a parking garage and I could not hear my exhaust. :( I was next to a Aston Martin and I could hear his exhaust as he slowly drove away. Now I'm looking Forward to get my exhaust soon.

Same here, my car is fully broken in (12k) and I can definitely tell the car is screaming to be opened up but those screams are muffled by such a weak exhaust systems. :(
