Smaller supercharger pulley

[RobXJC]

Evening

Anyone have experience fitting a smaller supercharger pulley?
Wondering if it’s doable with the charger fitted to the engine or best to remove the charger from the engine?
Cheers

Powerhouse Automotive https://powerhouse.uk/jaguar-supercharg ... r-pulleys/ fitted my 10% pulley with the supercharger in position about six years ago. The snout had to be machined down for clearance, but they have an in house designed and built tool to do this. For what they charged it didn't seem worth the hassle of doing it myself, in and out in a few hours.

Thanks for the reply, seems the snout of the charger is removed to machine it to size. So I’ll do that while the car is waiting for the salt to disappear from the roads.
Bit of satisfaction when I do the machining myself

Rob,

One can fit the 6% pulley in situ without any machining. I have fitted that on my Jaguar 4.2-engined Range Rover. It's only when you go up to the 10% pulley that it requires any necessary machining of the snout.

Good luck

Thank you, I was thinking the 10% pulley. For the extra effort I might as well do the machined snout.
I currently work part time in a technical college and the students do enjoy seeing the setups when I machine or modify my vehicle parts. Helps spark there interest in engineering.
