We found some minor issues during this sesson which caused a shredded belt. Better now then the street or stip. Best we could muster is 540rwhp @6000. As you know the 4v revs higher so there is more power to be had. We are hoping for over 600hp. Once the great guys at MMP finish up and Justion comes down for another session Ill post up the results.
