XKR XJR S Type R 4.0 Supercharger Lower Pulley Kit Giving 16% Boost !
Lower pulley kit for XKR, XJR, S Type R Giving 16% Performance Boost !
JAGUAR XJR XKR S TYPE R LOWER PULLEY UPGRADE
Lower pulleys have been produced to give a 16% power boost on 4.0 engines. Realistically, the lower will give a 40-45bhp increase, and will give perhaps 15bhp peak increase at high rpm, due to the Eaton M112’s reduced efficiency at higher rpm. Either ugraded upper and lower pulley produce a significant improvement and very noticeable increase in instant acceleration.
Our upgrade kit includes:
* a modified Jaguar lower crank pulley fitted with an aluminium lower supercharger pulley
* replacement supercharger drive belt
* replacement original Jaguar pulley bolt, and instructions.
These modified pulleys are CNC machined from the highest quality materials, produced to exacting standards. Fitting should take no longer than 2-3 hours by a competent mechanic.
Special Offer Price of £370.85 + shipping and VAT.
There is an additional £125 + VAT surcharge refunded on receipt of your old crank lower pulley and if OK for resuse.
No UK VAT to pay if you live outside of the UK and EEC Countries/
