Any Corvair Fans Here?

My much older cousin had one in the early 60's, not sure of the car's year. He wanted to show me how quick it was. We were stopped at an intersection, the light turned green and he basically side stepped the clutch. The car jumped into the intersection and about halfway across it felt like we got hit in the rear, the car shot forward. My cousin said "oh ****". I asked what happened. He just pulled over up the road and said the fan belt broke!

Damn, that cooling fan must have taken a serious amount of HP, when it broke the car felt like a booster rocket kicked in.......
we lost the belt on a 351C 71 Mustang on a freeway connector, long sweeping turn. We really felt it when it happened, like you said, a kick in the butt. My workmate had a corvair with an LT1 'vette motor behind the seat conversion, made it a mid engine car. Could not keep a rear end in it for some reason.
Dad had a 61 and it leaked exhaust into the cab. Did it have forced air heating across an exhaust like the VW did?
