alternator pulley

Last weekend at the track, I threw 2 belts.

I have an aftermarket alternator (Powermaster) with a 3" chrome pulley which was the culprit. Two factors come into play here; one is that the groove on the pulley is not very deep, the other is that the pulley is chromed, which makes it very "slick". This kind of set-up may be fine for the street where your generally not going to turn 6000 rpm's, but at the track the belts will fly off sooner or later. I solved the problem with a 5" underdrive pulley with a deep groove.

Naw, it lost a belt about a month ago, and I thought it was either a flaw in the belt or a misalignment. Never did find the belt, and I figured it broke but now I believe it just jumped off the tiny pulley. Hopefully, that won't happen again.

Last time I lost a belt it was due to the alternator and crank pulleys being mis-aligned.

I put on a March alternator bracket system and a Moroso underdrive crank pulley, all my problems are gone.

BTW - I found the belt a few weeks later inside the tranny blanket. How it got there, I don't know.

I'm pretty sure that's the same one I'm using.

Here's a few pics of it. Kinda hard to see in these pictures, though:

It makes life really easy. Installs easliy, is adjustable, and keeps the alternator in perfect alignment with the crank pulley.

I'm pretty sure Mancini Racing carries them. Ask for Wess.

Mike, will the March alternator bracket system work easily with a Maziere electric water pump?

I can't say for sure... But I don't see why it wouldn't. The bracket bolts to the front of the water pump (like the stock bracket). As long as there's a place for it to bolt too I don't see why it wouldn't work.
