Well the kits are damn expensive & power isn't all that great, but I altered the kit & added some things to make the car perform to my needs. I really don't want to get any discussion on superchargers, because it has been done too many times. So with that said supercharged rotaries are not for everyone, but I do love mine. When I finish my turbo RX i plan on maybe trying a centrifugal style. For anyone reading this, My intentions are not high power for the supercharged projects, but just to say I did it. I have plenty of time & am in no rush to produce these cars so in time I will post as I build them. Thanks for the compliments.
