(1 customer review)

Jaguar XJR Upper Supercharger Pulley Upgrade (2.5LB). 1998-Present Jaguar XJR 4.0L & 4.2L V-8 Upper Supercharger Pulley Upgrade (2.5LB).

Eurotoys Ltd. was the 1st to offer/manufacture these Blower pulleys for the XJR Jaguar.

This smaller supercharger pulley will give you a modest power improvement of approximately 30-33HP.

***Your car will still retain the factory belt, but “Modifications” to the blower are required! The nose-drive of the supercharger will have to be machined down to clear this small pulley. It is possible to do this machine work by “hand” with a Dremel or similar tool. Keep in mind that the supercharger can be damaged!

*Boost levels are subject to ambient air temperature, weather conditions and elevation.

**No ECU Tuning is required for this Supercharger Upgrade!

**The Rental program for this Special tool will cost $180.00. When the tool is returned undamaged, you will be refunded $120.00. So in the end, this tool rental will cost you $60.00 + Shipping (This tool can also be Purchased/Viewed in our Accessories section).

    Great product, the pulley is made of steel which is supposed to be better than the aluminum which can expand and slip with heat generation, real quality can’t wait for spring to test for more power.
