Jaguar S-Type R Upper Supercharger Pulley Upgrade 4.2L (2.5LB)
Jaguar S-Type R Upper Supercharger Pulley Upgrade 4.2L (2.5LB). 2003-Present Jaguar S-Type R 4.2L V-8 Upper Supercharger Pulley Upgrade (2.5LB).
Eurotoys Ltd. was the 1st to offer/manufacture these Blower pulleys for the S-Type R 4.2L Jaguar.
This smaller supercharger pulley will give you a modest power improvement of 30-33HP. The Pulley should be added along with Eurotoys supercharger porting and ECU Tuning for a major power gain.
*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. Eurotoys recommends that this is done professionally at our partners PSE Superchargers. However, 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!
**This Supercharger Pulley Requires a Special Removal/Installer Tool, which is available on our Rental program**
The Rental program for this Special tool will cost $145.00. When the tool is returned undamaged, you will be refunded $100.00. So in the end, this tool rental will cost you $45.00 + Shipping (This tool can also be Purchased/Viewed in our Accessories section).
