    Riva's dyno charts show 8.42psi @ 8100 RPM with just their 3" intake and stock IC. I never used a boost guage on my S2 to see what I was getting, but I think 8psi or just under would be more realistic for this wheel. I've heard Riva's numbers are a little better because they run ice water through the IC on their dyno, but I have no idea how much truth there is to that statement.

    IF that's true, no wonder the #'s never add up. The difference between theory and reality
