The TT Porsche Cayenne Turbo-S and the TT AMG-Benz SL65 don't want anything to do with the TT Z06 Chevy on the straight track. The TT Chevy dyno'd 755 RWHP and 676 RWTQ.
Gil, at NRP, assures me we could get another 100 HP by installing a .710 lift cam and a couple other do-dads, but I told him we'll just leave it be with factory cam...the 345's can't hang on with 750 HP, let alone 850 HP. It's sneaky quiet, viciously quick and behaves well in traffic. I sold the yellow supercharged C6 Z06...it wants nothing to do with this TT version either.
