i can't figure out why they would cast a whole new assembly, for a small gain of what 18hp?

W know ther is a gain in HP, but it is also due to: lighter rotors, higher compression, new exh manifold, diff turbo, evised ECU. What info is needed is: What is he ACTUAL FLOW difference due to new manifold design?

thats the part i dont understand, going from 5.5psi to 7.5psi should have done the hp gain by itself? so why cast a whole new shizzle?

Fo' my nizzle, yo!

I think i read somewhere that the S5 intercooler is "slightly" less restrictive then the S4.

I wish I know where I read this so I could post a link or something.
