Grunter Performance expectations
Standard the HDJ81 1HD-FT produces 368Nm of engine torque and 82-88rwkw. A Grunter Extreme turbo combined with a customized tune of the factory injection pump can expect 480-580 of engine torque and 120rwkw to 135rwkw. Boost should reach a minimum of 10psi at 1500rpm when tuned correctly. Installations with a large intercooler, 3” exhaust, custom injection pump and an upgraded air box and feed to turbo have yielded results as high as 165rwkw and torque over 700nm at the crankshaft.

Additional costs are required for tuning and installation.
