Totally. I dyno'd stock 641whp. So, who's to say there's any gain at all. Put it side by side in a race. |
Rob, are you sure 641whp? I think that may be extrapolated crank...544whp assuming 15% drivetrain loss is 641 crank. I dynoed yesterday 535whp, 487 ft-lbs, stock. |
Posted just before me!! Still, these beasts are way under-rated. FWIW, Rob and I got results on the same dyno but different days.
