5-7 kW might just cut it... probably enough to give your Jeep around... 5-6 psi of boost... ...the question is how much weight in capacitors or batteries you're willing to carry around?
yes it does, force= mass * velocity

mr. knights device was powered by 1 or 2 extra batteries required to power the 3 starter motors; and i think in the end the car was hauling around 200lbs more then it would have with a normal m62 or m90, completely making 5-6lbs of boost, negated by the additional weight.

ps. 15hp=12kW
