Can anyone help with advice on a supercharger pulley upgrade

[acollin5]

Having bought a Jaguar 5.0 supercharged V8 I was looking for a recommendation for a garage who have experience on performing an upper pulley swap on the supercharger around the Edinburgh area. Willing to travel further if it means I know the garage is experienced in doing this sort of work. Recommendations please.

Also for those who have already carried out this upgrade I would welcome your thoughts/results.

Thanks!

Thanks everyone! Bought the pulley from Powerhouse and in the interim since the post have now found an independent Jaguar garage who have experience in doing the work even on their own cars, including a 5.0 XK-R. It is only a 6% pulley so will give a small amount of boost increase across the rev range - 20bhp typically - but not pose any other fuelling or cooling issues that you might see with a smaller pulley. Ultimately it is for improved acceleration to use in instances few and far between as it boosts slightly lower and fairly evenly. Never found grip a problem (rwd) - if you are sensitive to it. In the wet - yes - you have have to be careful.

What a positive buying experience - thumbs up for Powerhouse too - excellent after sales service. Car is wonderful, wonderful, wonderful.
