Phi and MMC, I understand your point but what I'm saying is different. Power is made on flow. The car clearly has the ability to flow more than the stage 1 rotrex unit does. So that tells me that you could use a bigger unit that flows more which would make more power. A bigger unit would flow more and start getting choked up by the amount of flow of the actual motor, thats when you would see PSI start to rise.

So no, its not that people are obsessed with psi numbers, its that you could be making more power because the ENGINE is capable of flowing more than the SC does.
