On our Superflow Engine Dyno, the Stage 2 Exterminator Kit peaked at 164.3hp @ 8300RPM and 103.9ft-lbs at 8100RPM- an increase of 12.3hp and 6.5ft-lbs at the peak over stock. The higher RPM and much improved over-rev power approaching 8500RPM means it will be much more forgiving on the clutch setup than the stocker and will have bigger wheels on the top end for the long pulls on the lake or the big climbs in the mountains.
