Well I am not sure how much HP my shee has But the people I have talked to told me it should be about 70HP.
And I Drag Raced a Shee with clamp on K&N air filters and HoleShot Rear tires and I won in 300 ft.
He is about 125 LBS give or Take and I am 270-280 and his best time is 7.335 and Mine is 6.033. I now My shee will run faster then that. But on that track I would spin from 1st all the way to Top of 5th. And I cross the 300ft Line in top of 5th.
But I will be going back in septerber with Self Tapping screws in my rear Tires and a Lightened FlyWheel.
