Hey Folks, just my evil mind thinking of doing something different and maybe get some big gains. AC has a 660 Turbo in their snowmobile line up! Gimmy your 2 cents on doing a transplant into my 650H1 2006 Prowler. I drove one a few years ago and just cant get it off my mind. I think it was a Pantera Touring sled. That thing would run up to over 90MPH in no time at all. The extra torque from the Turbo is sick and just makes me drule at the possibilities. I also think it makes well over 90 Horse Power.
