370Z Equipped with HKS Intake System, Racing Suction Reloaded

It is possible you may loose some HP when the hood is down and the car is running hot. The reason for this is due to the lack of a heat shield. Once the temperture inside the engine bay is hot, the intakes are now sucking in hot air.

With the hood up on a dyno... i bet it does gain a few HP on the top end, while losing a few on the bottom. Essentially your shifting your powerband higher in the RPM range.

I currently have Gen 3's, Stillen CBE and Berk HFC's. I do feel like i gained some up top!

I DEFINITELY feel like I gained some up top, i have the same mods, but I also definitely feel a loss in low end torque, I'm hoping this Cobb Accessport will get my torque back. And as far as the HKS intakes, they're short rams, and without heat shields no less. Basically when the engine gets hot, they're consistently heat soaking and pulling in hot air. The Stillen and Injen intakes are positioned in such a fashion that they pull the coolest air possible, thus the huge gains they make. Hey Nitex, have you touched your intakes after a few spirited runs or after a drag? Ice cold to the touch every time i've done it, apparently they really do pull in cold air
