So I've heard that the transmission in the 2015-2016 R/T Scat Pack and SRT 392 can only handle about 600-650 horsepower at the crank, and my goal was to put my future car into the 550-600 horsepower range so I'm getting somewhere around 480-540 to the wheels. What can I do to upgrade the transmission to handle the greater stress? Or would I maybe have to upgrade to a Hellcat transmission, the HP90? Also, what about the driveshaft and the rear axle?
