Hello all, does anybody know which supercharger pulley to use on a X308 XJR that has Supercharger Tensioner Kit (Supercharger tensioner & belt upgrade kit includes modified tensioner
idler & mounting bracket plus supercharge drive belt) ?

Surely the original smooth pulley isn’t going to be correct since the kit contains a supercharger belt which is ribbed / grooved on both sides. I was thinking of adding the pulley from the X350 (2003 - onwards), C2S46862 ?

Any thoughts / advice would be welcome.

Thanxs

 

The kit as shown on the pic in the link you provided is correct - ribbed idler pulley (on the provided bracket) and smooth pulley on the tensioner. The ribbed side of the belt, that goes over the tensioner pulley, rides on the smooth wheel. This is how it was installed in the factory at one time. Having the ribbed face of the belt on the smooth pulley was deliberate concept to reduce the belt squeaks.

 

Hi thanxs, for your reply. Do you know what original pulley / part number is on the snout of the supercharger ?
