Switzer is a master of horsepower! Their latest upgrade package for the Nissan GTR R35, an evolution of R1K package, hits the dyno and delivers a staggering 1250 AWHP and 1003 AWTQ. That’s more than the Bugatti Veyron SuperSport! Granted, those number achieved with race fuel, but they promise a test with 93 octane pump gas will be conducted soon. This R1K-X package is under development, and who knows, maybe they got more out of it!
