Hey fellas,

Kind of corn-fused about the conversation so far? (but interested!!)

Dee-a American produced compressor pulley on the metric S/C shaft? Seems like shaft length and diameter would a much more important issue? Whether it's keyed on or bolt tightened? any previous research available on this? 5 rib yes, 6 rib I wouldn't.

Jason-the JDM Supercharger has a smaller pulley? Cool, never knew that.
I don't get the "run all the time" statement? if you replace the OEM pulley with the JDM OEM why wouldn't the JDM unit also have a electro-magnetic clutch?

Just to add a question to the mix? If you check the sc-12 specifications between a automatic S/C car and a manual S/C car the automatic has a higher boost, interesting huh?

BTW This Club's archive section might be worth reviewing, it offers much previous discussions on crank pulley replacement options and resultant boost results etc.

Hey Dee what's a fmic?
