This Jaguar XF upgraded supercharger pulley really helps improve throttle response and midrange power by as much as 25bhp. It will bring your Jaguar XF 4.2 to life, boosting power across the full rev range. The additional boost pressure is felt straight away, and the power comes in smoother and faster, and just keep pulling.
Paramount were the first to adopt and develop the new style of Jaguar XF 4.2 modified upper supercharger pulleys. Originally designed and fitted to the 4.0 engine fitted to the XKR. And then redesigned for the 4.2 engine fitted to the Jaguar S type and XKR. The advantage of the upper supercharger pulley upgrade is it’s cheaper and uses the original Jaguar supercharger belt.
Unlike the more expensive lower supercharger pulley upgrade. The upper smaller Jaguar XF supercharger pulley we supply does not require an alternative pulley belt. Also means the Paramount supercharger pulley is low maintenance and less obviously changed from stock.
Please be aware not all Jaguar performance supercharger pulleys are equal, some require the nose of the supercharger to be ground down. This is not ideal as the pulley is too small and leads to the belt slipping. Others have poor machining, and can come loose or worse! Paramount has supplied over 600 Jaguar supercharger pullies. And routinely fit 2 a day, day in day out at our workshop. Trust the experts. – buy with confidence from Paramount.
If your pulley upgrade is part of a bigger quest for power and performance. We can highly recommend the Paramount Jaguar XF tuning service. A custom tune and ECU remap to go with your pulley. Available for the 4.2 and 5.0 V8 supercharged engines. The two together deliver blisteringly quick performance, torque and acceleration. A match made in driving heaven.
