LMR added some minor modifications to a 2015 Chevrolet Corvette C7 Z06 which added over 110 horsepower to the wheels on their DynoJet.   The modifications included a different size supercharger pulley, American Racing 2″ headers, X-Pipe and a custom LMR ECU tune.

In stock form the Z06 put down 559 horsepower and 543 ft-lbs of torque and after the modifications and tuning the results were impressive at 661 horsepower and 626 ft-lbs of torque.   Using a 14% drivetrain loss on the 7 speed manual transmission that puts this Z06 at 760HP.
