Supercharger belt
 

Hi , my 4.2 xkr have this supercharger belt:
2W93 8620 EB
i have a stage 2 upper pulley.
Where i Can find It a Little more short belt ? Part Number?

Thank you

I presume your belt is slipping?

I have a similar setup and bought my super charger belt on Ebay and no slipping whatsoever.

Its the standard belt for a 2005 XJR.

Is your idler pulley setup working properly?

not slipping. Only that will be better a little more short belt

If your existing belt is not slipping then I do not understand why you want a "tighter" belt?

I WANT IT BECAUSE WITH STAGE 2 SMALL UPPER PULLEY IT WILL BE BETTER THAN OEM !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!

understand now?

Why would it be better? If it is not slipping and is moving the pulley with no problem what benefits would a tighter belt provide?

None I can think of. Hoping to hear...

I have the whole new engine and the belt, even if it does not slip, is old and I have to replace it. And since I have to replace it, I thought I'd put a slightly shorter one.

Ok understand now...

Problem is that on belts that I see advertised they do not give measurements just "compatible vehicles".
