Switzer Performance had another one of their R1K upgrade package Nissan GT-R's on the dyno and it put down some impressive numbers. 1026 all wheel horsepower, and 960 ft/lbs of torque. This car is running an unsleeved block, with aftermarket pistons and rods. Switzer does not like the idea of sleeving the block, and they are sticking with the stock unaltered aluminum block until they reach a limit.
Just to clarify, this is on the stock block, stock crank, stock heads with just upgraded cams, pistons, and rods, professionally blueprinted and assembled by Tym Switzer Sr.
