I just purchased the JAGUAR XKR SUPERCHARGER PULLEY UPGRADE KIT 2010-2011 5.0L MODELS from Mina Gallaries. Anyone have any experience installing them or with the product? Does it really boost you up to 25 HP

 

Hi Jerome,

You need to post your question, which is highly SPECIFIC to your model, variant etc in the dedicated forum section devoted to these cars.

Cheers,

Ken

 

I've moved your question from General Tech Help to XK/XKR forum. This is the place to post technical questions about your model.

Can't see much difference in doing a 5.0 and a 4.2, Had mine done and went for 10% 2.5lb pulley,

The snout of the supercharger had to be filed down by 2mm all round for the small pulley. I bought the pulley of powerhouseuk. They told me it could be fitted without removing the supercharger , but it is impossible to get a good job done this way and would have caused a mess.
The guy who done it for me (Ken) took the supercharger off and did it on a bench. The coolant had to be drained and throttle body taken off and another few pieces. The supercharger belt still fitted when the work was finished.
I had mine remapped as well by Black Code Remapping.

The only mod i had was the performance exhaust. Top end is near the same ,but lower end is astonishing. The slightest touch of throttle and it's gone. Seems to change up the gears quicker and smoother. The power up to 3,000 revs is massive. It's just hard to describe, simply amazing.
