If it is what I'm thinking it is... I'm not scared of that either. but I'm not going to count my chickens before they hatch.
190tq (average across power band) and a 66mph 2nd gear (your car?)
250tq (average across power band) and a 81mph 2nd gear
because of the gearing it's only 7% more torque that needs to be put to the ground...
the real difference should be in the shape of the curve
165tq @ 9500 = 298whp
260tq @ 9500 = 470whp
superchargers are cool...
