2-piece Power/Amp series pulleys
After a lot of dispute I figure they're cheap enough ($50 for the set) I might as well get them anyways. The only question I have is will I need a bigger belt or a smaller one? About how much bigger/smaller? Don't know if it matters but I've alread ditched the AIR pump.
I called March to see which PN fit they gave two one was for the 3-piece aluminum (didn't want this set so didn't keep the PN) and another for 2-piece steel which is 4405 or MCH-4405 if you're looking on summit.

Well they're on there now, wasn't much of a SOTP difference but it does seem to revv a little easier. There was absolutely no drop in voltage so thats a plus. I'm probably going to the track Wednesday so we'll see if I'm quicker.

Nothing has gone wrong yet, temp is the same as it always has been and so is the voltage reading. I went to the track tonight and ran a 16.81 down from bone stock of 17.55. Nothing spectacular but I'm getting there.

Im glad to hear that they worked out for you...considering so many people think its not worth it. Im looking to get the Power and Amp Series 2 piece set in the spring. How much did the belt run you?

It was just a cheap dayco, most people swear by gatorback, I really think a belt is a belt though. It was about $25
