Its a tough concept Travis, but if you UD the crank pulley by 25%, then the stock alt pulley will move 25% slower. If you match the 25% UD crank with a 23% UD alt, it will spin about the same RPMs as before. I get full charge of the alt at just 750 rpms...

Ah I see. It makes perfect sense. Just was going off what I heard you know. What did you pay for your set?

Stupid iPhone likes to change words on me from time to time.
Where did you pick them up from?

not to get too technical but it would be:
an overdrive if its a smaller driven or a larger drive
an underdrive if its larger driven or a smaller drive
drive is crank
driven is wp/ps/alt
you have an underdrive crank pulley, and an overdrive alt pulley

Oh, they work well on F*** too, in my experience. I have the March aluminum 3-piece set on my Mustang (crank, water pump, alt), right when they introduced the Power & Amp series to correct low idle voltage (which it evidently did, never had a problem). I'm guessing I've had them on my car since '97 or so.
