I'm buying a 96 XJR, which uses the M90 as well (95-97, and pre 94 Aston Martin DB7s).
Well guess what: Pullies marketed for jags are bloody expensive, and I was hoping to get some useful CFM or % numbers for the available pullies. Tuning will be a whole different animal, anybody know Lucas ECUs? :tongue:

Also, anybody have the actual outer diameter measurements of the after market pulleys? This one is already spinning 322hp worth of air, maybe SC pulleys are actually bigger.

Thanks
Eric

Check out the pulley boys. Just find out of your pulley is keyed first. If it's not keyed you can get the quickchange system which i love.

Just out of curiosity have you checked jag-lovers.org? That forum was of great help to me with my '85 XJ6. The only annoying thing is you have to register to search but I'm pretty sure its still free.

also zzperformance.com sells pulleys for the series 1 GM L67 which I believe is a keyed pulley.
