Even though Tom does excellent work I have to agree the RPM-II or a box upper would be better and give you a lot more room to grow. The upper cobra intake is the bottle neck anyway.....unless you are running boost then all bets are off...

I don't doubt what you say, I think you and the others are pretty sharp too. I just want to maximize my combo with the heads and cam I have now.

The cobra intake is a torque maker though but for higher rpm cam such as what you have, you would benefit from the shorter runners of a RPM II while maintaining decent daily driving power. I can tell you that the cobra intake likes 14 psi though

Not anymore as it likes the NA route now.... The TFS-R that is taking it's place will like the 14-15 psi of boost....
