Jaguar XJ8R XK8R 1997 on supercharger pulley upgrade!! | eBay

Thoughts? After all the work I've done getting this motor torn down I'm ready to pull the trigger on some upgrades ...

EDIT: I suppose I'm really asking if anyone has heard of or bought from this particular manufacturer. Seems comparatively cheap for both pulleys, and I'm a bit wary.

 

Steer clear, it's aluminium and WILL slip, the upper pulley HAS to be steel. Ally ones heat, and when hot the belt slips. Steel doesn't, look for stainless upper pulley.

TBH, a crank pulley is the one, out of the two to go for in my opinion.

 

Yeah, I passed on this one. Turns out it's not both pulleys anyways, just a misleading photo.
