The V10 water pump pulley is bigger. Yes it will turn slightly slower, but the engine won't notice any difference.

The V10 water pump pulley "upgrade" is something us Saleen blower guys do to get more wrap around our blower pulley.

 

Good stuff, thanks for the info. I had that backwards with the pulley size.

Anyways, I got the belts from Race Mart and they look perfect. Can't go wrong at 24 bucks a belt. I also installed the Roush tensioner and it looks pretty beefy compared to the stocker. Soo far no problems and back to normal.

 

anyone have the belt diagram with the supercharger on it? My belt broke...
