How much torque can the transmission handle in a Super-charged Engine? I have a 1994 Viper that has a Roe Supercharger installed. The engine is dyno at 620 horsepower to the rear wheels. I already have had trouble with it being too much power for the half-shafts and had to replace them with high-performance ones. Then the rear spider gears broke, and I am in the process of replacing them. I'd love feedback on others who have Roe superchargers on their Vipers.
