You might also look for a narrower belt that sits deeper in the pulleys

And you are convinced pulleys are in align? At high RPM, doesn't have to be much off to throw the belt. For short run, I certainly would run belt as loose as possible.

Make yourself a belt guard from 1/8" thick aluminum.
Easy to do.
Lay it out as centered as possible and make round in a lathe or use a drill press, mandrel and file to round off the outer edges.

The one shown is on a Pinto alternator.
There's usually enough threads on the shaft to bolt the guard directly to the pulley.

Never lost a belt with one of these - not up to 6200 rpm anyway....

DennyW's got a good point here.

A fully charged battery allows your killer ignition system to work as it was designed.

Most cars that have run an ignition system on battery only find they turn faster times with an alternator keeping the battery up.

So much for the old wives tales about HP loss due to the drag of an alternator....
