An increase in torque without a corresponding increase in hp? I'd love to hear you explain that one.

Aw, I'll give you a break. torque x rpm / 5252 = HP

So any increase in torque automatically increases hp.

You can thank frozen Margaritas for the free ride :laugh:

BIULD it as strong as you like run the shit out of it then fix what breaks
its the only way to know for sure
