Gaging interest in a quick change pulley setup for M90 blowers that would allow you to run the MP 10% crank pulley and 10% JS pulley along with your choice of either a stock blower pulley or a 10% OD pulley. Other ratio's would be possible but those two would allow for the best choices. A 20% total ratio would provide 16-17psi on the street for safety with pump gas and then the 30% ratio would provide close to 20psi for track use. Other ratio's could be easily made after the hub/pulley setup is installed.
Drive ratio's higher than 30% have been tried with success for those who might want to try it. These pulleys would feature revised rib design, media blasted drive surfaces, and hard anodizing for maximum grip and long life.
Please post if you'd be interested in purchasing. If there is enough interest we will bring back a cost estimate. Looking for an initial run of 10 units for cost projections.
