Lancer_Jordan: PMed ya. And the Crank pulley install wasn't bad. I've been driving on it for almost 2 years with no problems. Definitely worth the money. Also, mine is NOT an underdrive pulley. IMO underdriving sux because you have less power going to the alternator, which makes your car idle like crap. The lightweight one simply replaces your 8lb pulley with an aluminum one that's the exact same size but only weighs 15oz!

True, but the alternator is regulated (gotta love solid state electronics), if you ever hooked up a voltmeter to an underdriven Spec, you will see that the volts are still the same as stock. But this effect WILL come into play, say... uhhh... at idle, w/ the AC on, headlights on bright, fogs on, and a big audio setup. LOL. Anything over idle though and you should be fine to underdrive.
