The stock ITR manifold will flow plenty of air for any hp level and you will not have to sacrifice and low end drivability.

Aparently even with a mild buildup like the one they had in the article they lost tq.
HOWEVER they also gained a good amount of hp, and I'd have to wonder... had this person been more wildly built.... how much of a gain would he had?
