I've heard that it put's out around 65 HP. It has a new pipe that gives it a ton of bottom end touque and still better power on top. The cylinder porting has also been changed to give it the better peak power. Along with a new ingition system that works better than the old one. It should be the one out front if all the hype I've heard is true. It should be the best fan motor Polaris has ever put in a race sled.
