I've had u/d pulleys on my car for years now, and I loved them. the problem i'm having now is that i've added so many accessories to my car (2 amplifiers, nos heater, electric fan, msd6al,.......) that at idle, the voltage gauge drops right down.
My question is, could the pulleys also cost hp due to having a weak ignition system (especially in the lower rpm range?)
