HD-G300 Vortex Greens enhance low down response + the ability to carry the boost efficiently throughout the rev range. Its design boost is 22psi and can be operated efficiently from 14 – 28psi. Fitting a boost controller and boost gauge will allow you to increase boost over the preset 18 – 22psi.
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 airbox and feed to turbo have yielded results as high as 165rwkw and torque over 700nm at the crankshaft.
