PSI question

[handinpants]

So with all the talk of running different turbos on a stock set up, how would 10 psi on a t25 be different from 10 psi on a t28 and why would running the same psi pressure level on the t28 be vastly different?

Because it moves a greater volume of air and doesn't have to spin as fast thus keeping the intake charge a lil cooler making it more efficient = more power.

oh, wow, i totally forgot to put the volume of air into the equation...
