this crazy contraption is built on a john Deere frame and has the original transaxle. we changed the pulleys and installed a Briggs 16.5 hp V twin motor. that went relatively fast but it wasn't good enough. we got the idea to use a leaf blower as a supercharger. so we installed the turbine Assembly from the leaf blower and attached it to the drive belt and ran a pipe up to the carbureator. we get about 100 hp out of it now. it gets up to about 9000 Rpm on nitromethane racing fuel. it goes about 30 Mph now. pictures coming soon.
