On left is fully built stroker rzr with 14 psi boost middle is rzr s with mpi supercharger with 7.5 psi built by krazyhousecustoms with dm racing auto tune set up. On right is dm racing natural aspirated stroker motor this motor does not have high compression because it is going to get turbo.
I have a hard time trusting any dyno runs with a CVT. It's really easy to inflate the numbers with clutch tuning. AIRDAM is the only one that has talked about setting up the clutch so it shifts out really early and gets true engine acceleration numbers rather than winding up the motor and recording the acceleration of the clutch like in that video. I'm not saying the supercharger sucks, just saying that dyno run is not accurate.
