I currently have a 200 amp alternator in my car, 2 batteries from when i had a crazy sound system in my car before most of the system got stolen and i spent the money on the 383 motor setup i am doing. I also have all 0 gauge wires b/t the batteries and alternator and all grounds.

just wondering if an underdrive pulley kit will still help with a beefed up electrical setup like this? if it does help, is it because the pulleys are smaller so it rotates faster?

thanks

does it really matter which brand you get if it is worth it with a beefed up electrical system?

 

UD pullies dont give much peak HP but under the curve power vastly improves. In essence when going in a straight line, the only thing effected is the Alt. When the A/C is off, its off (clutch is not engaged), and Power steering is just there cus your going straight.

You put a 200 amp alternator on the car, if you just get the crank pulley, the car will not put out as much juice, if you get the ALT pulley to go along with it, all you are under driving is the power steering.... so there wouldnt be much gain.

I am actually going back to a stock sized crank pulley because I want all the cold cranking power i can get.

 

I ran underdrive pullies and had a huge system. 3 amps, crossover, equalizer, cd changer, 4 10's and also had every speaker in the factory postions running off one of my amps and never had a problem.
