Vauxhall Monaro model: the VXR 500. A Harrop supercharger was installed onto the standard GM 6.0 LS2 engine by Vauxhall dealer Greens of Rainham in conjunction with tuning firm Wortec, bumping up power to 500 bhp (373 kW) and bumping up torque as well to 500 lbf·ft (677 N·m). In addition to this, a shorter gear linkage was added to enable quicker shifts. The resultant acceleration times too were impressive at 4.8 seconds from rest to 62 mph
