I broke a green belt on track at a little over 16,000 miles. Now at 35,500 with lots of track time, the green belt is still holding but I keep a spare and tools to change with me. Have an RPM belt, but have heard mixed reviews on them.

Love my nice looking and softer black one.
I know what my previous car did and at 20k when I saw it last, that sold me.

Been a while since last post in this thread. Two questions.

The color of the black aftermarket supercharger belt - not enough information to pre-emptively change from OEM green belt. Does anyone know the brand and part number of the black belt?

If a supercharger belt fails what happens? Does it always damage the engine or the supercharger? Or would it damage the engine or supercharger only if it unravels at high RPM's?

Thanks in advance for any info.

I believe the black belt is:
Bando 10PK1504ASP

If the belt fails, damage depends on where the pieces of the belt wind up.
I've seen some posts where it gets caught behind a pulley and wedged--possibly damaging the bearing, sometimes even scarring the timing cover.
As for damaging the SC--unless the belt jams the snout pulley and causes a hard stop on the SC, I don't think a broken belt would hurt the SC--it would just spin down and you'd have no boost--probably a rich condition--not sure how the ECU would react to that--maybe it could cause other issues?

It does just fine with a black and not a green belt. It did another course day without a wimper.

I'm going to get one - I've followed your two supercharger failures. You and Trackway are the pathfinders!

Next question...is this a DIY supercharger belt change or better left to someone with specialized tools?

If you have typical tools, done at home with only moderate swearing.

Getting the intake out of the way helps!

That alone is the first PIA, maybe not so much coming out but @Finface that little activity has made you swear before, going back in right?

Much harder on the vehicle than a drag strip. Credit to those that chose this path.
