Pulley sizes for Paxton SN93?
Installing an SN 93, and want to back figure pulley size from supercharger impeller speed (maximum). Does anyone know the maximum impeller speed Paxton recomended?
Also, what size is the factory crankshaft pulley? Is the ratio in the supercharger 4.4:1?
Thanks for your help.

pulley diam is 4.25 inch
"redline" rpm for that sc........it all depends.......some folk have run them up to 50000 with no problems....
I only occ'l go to 6000 engine rpm-usually shift at 5600 or so and have not had any problems. But honestly, if you're gonna hammer on it all the time I'd consider something else; if you change the pulley size to keep it within "recommended redline" you won't end up with much boost....unless you shift at 5000rpm.
For further info check with Paradise wheels in San Marcos, Ca. 760-740-0954.
They're the official rebuilders/servicer for ball drive paxtons now. They've been good to work with for me.
