The WEAPON-X carbon fiber intake has been a monster out in the real world already having powered LT4 equipped cars as fast as 10.1 @ 138MPH with some other mods. We have two versions and our stage 1 is no tune required which allows the supercharger whine to be much more prominent! Our stage 2 requires a tune and our recent Whipple install resulted in nearly 700whp with just our stage 2 intake and a cat delete.
Our average gains have been 28whp!
