Im looking to upgrade the boost on my stock z6 with a JR supercharger
Right Now i am running 3 - 5 psi of boost
I would like to be running 8 - 10 or 10 - 12 psi
Where should I order pulleys from? Ive been looking on a lot of different sites but I cant fid one for my specific aplication
What size pulleys will I need to order to get the desired amount of boost
thanks

get a bigger unit. M45 just too small. When spun faster it just heats everything up too much.

You could try a 8psi pulley from Jackson.......

Find a B series M60 and go from there. 12 psi from that is going to be a lot cooler than 12 from the M45.
