you'll get 8 from a 25% ud pulley, go with a 42% and you'll pick up 12.

I'm running a MMATS 4070 competition amp, and my battery lasted 3 years, which is a little short.

If you're worried about charging, puck up an alternator overdrive pulley from ASP. You'll still be WAY ahead on hp/tq

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
