DYNOTRONICS QUIK CHANGE
This is the thing that has been missing from the MP62 based Flyin Miata SuperCharger for the MX5. With this set up you can change the pulley size( and the boost!), with a simple Allen wrench, and a 14 mm spanner.
This is the same set up we use for our 2.5 conversions with the FMSC, allowing us to reach 290 plus streetable wheel horsepower on E85 with a STOCK MZR 2.5!!!!
Featuring a stainless steel hub with a black anodized aluminum alloy pulley and stainless steel hardware
Pulley sizes 2.7" and smaller require clearance machining of the supercharger casting for fitment. Please see FMSC-1101-MFC for our pre-machined front casting if you wish to run a pulley down to 2.4 inches.
