Here's an interesting tidbit for those that, like me, are "electrically challenged." Buying a higher-output alternator to compensate for spinning it slower doesn't work! It actually makes it worse!
My car revs out to 7000 RPM, and as such, it would normally overspin an alternator and damage it. My UD crank pulley helps prevent overspinning, but with an 800-900 RPM idle, I've found that my 200 Amp alternator is only putting out 11.8 volts. I called PA Performance and Rick there explained, politely in barney style, that, and I'm paraphrasing, I'm a moron for doing all that stuff. A 130 Amp, if it's enough current, will actually put out more voltage for me. He said I should probably idle it at 900-950, and I'll be getting plenty of voltage.
I'm not sure if my Weldon pump, Engine Management, high output coil, etc... are drawing more amps, but I'm guessing a 130 will be plenty. So, I've got one on the way. Will update when I install it.
