Well I'll let them sort the points out. The record setting Tyson/Bernard bike ran 22lbs of boost. Magnussen supercharger, 7.65 @ 174mph I believe, was looking at Tom McCarthy notes. Aluminum Ralph Muldoon frame...made in 6 hours straight work! 1000cc , 90% nitromethane, way cool, just had a hot shower, so did everyone else, big home run it is! Lol, Bill
