I have a 2012 FX Cruiser SHO with R&D Stage 2 kit. Has 160 mm impeller. Am adding cam gear kit and supercharger cooling housing. Currently running 8430 on average rpms at 75 plus before adding the new cam gear and supercharger cooler housing. Concerned about going to rev limiter. Am buying a new Skat Track impeller to absorb rpm increase. Thinking of a 14/23 160mm Skat Track. Any recommendations? Wish to obtain max speed and stay around 8400 rpms.
