I'm making 304 whp and 289 wtq on 8.5 PSI stock block, stock head, stock timing maps -2* base, stock ECU SAFC tuning, pump gas, I'd run more boost but I was happy breaking 300 at 8.5......... 450-500 whp would be cake on a built bottom end and deffinatly different.

The crank for the 2007 Spec V, and Spec V only, is now fully counter ballanced and the factory redline was bumped to 7K.
