Supercharged Nypro

Looking into jumping on the bandwagon and put a nytro motor into a pro rmk. I love they way the pro's ride but just to underpowered after riding Yamaha's.
Just thought I'd start a thread for some ideas. I have 2008 nytro mtx motor with a 280hp mpi supercharger on it. Looking to put it in a 2011 pro rmk. I have seen multiple builds where they use polaris secondary clutch and gear case. I'm not sure if they can handle a nytro motor. Any sugjustions to use a Yamaha secondary clutch? Was also thinking of switching to a belt drive kit if that would handle the power better. Just looking for some other opinions. Thanks

Ok thanks. I plan to modify the bulk head to handle the extra weight/power. But i also will probably never run the full 280hp. It will prob be set around the 220hp with 50/50 race gas mix, but there is always those times when its fun to turn it up so i hope the chassis will hold together for that. I am also thinking i will end up going with an aftermarket belt drive kit instead of the chain case. I think i will end up mating the yamaha and polaris jackshaft to use the yamaha clutch since i have that already sprung and different helix for that motor.
