in the 20v turbos, Ned says the stock turbo (K24) is good for about 320 to 340 hp--that's with about 3.0 bar absolute (2.0 bar boost). don't know what this means for the 10v cars, but....;) Wow! Cool, I've only been running 2 Bar/15 PSI, I've got another 1 Bar/15 PSI to play with with the S4/K24. -glen
