HeHe... Keep the cage my friend. My dad built a single seat dune buggy with a VW Bug motor back in 75 that he had balanced and blue printed at 175hp. He was in the trinity river bottoms, had him right hand on the roll bar and rolled the car.
The hand was re-attached and you would never know it happened by looking at it. Safety Rules
My car only weighs 3600 lbs and a German tuned suspension, so it will scoot with 300 hp
