This quote shows a stock 800 Razor at less than 32hp at the wheels. Not vouching for integrity here just sharing.......



"There is no dune this buggy can't climb with this turbo kit. It brings the best of both worlds in reliability and great horsepower. 8lbs of boost is laying down 64HP at the rear wheels. This is over double of the stock RZR at the rear wheels."

 

I can believe that with the razor, after all my 800 only had 4 more hp and you can scratch that off to differences in dyno's. I believe the Polaris 800 at the crank has only 48 hp. Losing 25% due to driveline and clutching would put you at about 36 or so. With the XP you should get around 53 hp at the rear wheels.

 

Just remember different dyno's give different numbers. I've seen 10hp differences from what one guy got on his dyno from what another guy got on another. Some are stingy and some are plentiful. The only way to see how this dyno is, is by putting a Outty on right after. Then you would know.
