On 12 volts it was a tick faster with the alternator charging. Did slow it down some with pulleys. Had to have it aligned well to keep belts on at 8500.

Going up the track alternator on I'm at 14 volts, Alternator off 11 volts

Ed I'm CHEAP. I'm not going to spend the money to go to a 16 volt system. I just put new rings and bearings in it. That exceeded my yearly budget. I'm still running store bought street headers.
I'm planning on selling the car in the not to distant future. So if someone buys it they can do those things.
