Jaguar XKR, Lower Supercharger Pulley Upgrade 4.0L
Jaguar XKR, Lower Supercharger Pulley Upgrade 4.0L. Eurotoys Ltd. 1998-2003 Jaguar XKR 4.0L V-8 Lower Supercharger Pulley Upgrade.
*This listing is for modifying your lower pulley. You will have to send us your pulley.
This supercharger pulley provides a substantial power improvement over stock due to the 4.5 PSI* increase in boost. When used with the stock Jaguar upper supercharger pulley, a total peak boost of 16 to 16.5 PSI* can be achieved.
This Lower pulley assembly is a 2-piece design which allows you to remove the outer Blower Drive Ring without removing the entire pulley assembly from the engine. This comes with our standard size ring. (Other optional Blower Drive Rings are available to tailor boost settings for your driving style).
If you would like a different boost level at time of purchase, we can outfit this set-up with a different outer ring, for the same price. You do not need the Eurotoys upper supercharger pulley or a separate drive ring to go with this.
*Approximately a 2 week turn around on pulley. 2002-2003 lower pulleys take a little longer.
* Measured Boost/PSI levels are subject to weather conditions and vehicle performance. All values given are approximate for Supercharger speed/engine RPM.
*No Eurotoys ECU Tuning is required for this Supercharger Upgrade!
