Well, yes and no. Its the water/air intercooler that lowers the intake temps, allowing you to run more boost on pump, and the fact that you have a larger turbo that allows you to make more horsepower per pound of boost pressure. A GT35R makes more horsepower at 10# than a Mitsu 16G on the same motor. It has to do with CFM . . .
