First dyno 247@8psi on a SE block. I now have a street ported hybrid Turbo block and 10lbs of boost. I'm taking it back to the dyno sometime next week. By the way it was a S4 turbo.

Whats the max HP you've pulled out of a stock S4/S5 turbo?

 

i made 240hp @ 6200rpm @ 10psi on a dynapack with tired S4 block, S5 turbo with stock wastegate, racing beat turboback and APC filter. no other power mods.
