Jeep Grand Cherokee SRT8/620 Supercharger

The Trackhawk alternative.

Already ex works the Jeep Grand Cherokee SRT8 (468 hp/624Nm) is anything but underpowered. But you don't get used to anything faster than to performance. For this reason we supplied the Grand Cherokee WK2 with even more power.

2.65-litre compressor generates a whopping 620 hp

Together with the US-American performance specialist Edelbrock, we have developed a TÜV-approved compressor kit. With a gentle boost pressure of approx. 0.5 bar, the 6.4-litre V8 engine develops a full 620 hp and a torque of 756 Nm after the overhaul. Our compressor kit is supported by a larger intercooler, adapted engine electronics and optimized fuel injection system.

One special feature is the screw compressor placed between the cylinder banks. Thanks to the proud chamber volume of 2.65 litres, the compressor can force the engine to breathe even at low speeds. In addition, the low compression of the charge air ensures a lower charge air temperature and thus more efficient charging.

Custom-made flap exhaust system with EC approval

The resulting exhaust gases are discharged through a stainless steel flap exhaust system specially developed for the GME Grand Cherokee. The dual-pipe sports exhaust system with X-Pipe, damper control and 114 mm tailpipes (optionally made of carbon or polished) even has EC approval. This means that it can be installed and registered without any problems. The system is designed in such a way that it optimally underlines the pithy and characteristic V8 sound. Inside, the well insulated body keeps the car unobtrusively quiet and allows a pleasant conversation with your passenger even at higher speeds.

8-piston brake system and 22-inch forged wheels

Because the enormous power needs to be restrained, especially when it has set a good 2.4 tons vehicle in motion, we have installed a powerful 8-piston brake system with two-part 400mm brake discs on the front axle and a 4-piston brake system with 356mm discs on the rear axle. This also fits under the stock SRT rims.

To underline the performance of the GME Grand Cherokee, however, the original SRT rims had to give way. These were replaced by two-part forged rims made of high-strength forged aluminium designed by us. Thanks to a larger rim width and a modified offset, the wheels fit perfectly in the wheel arch and increase driving stability thanks to a slightly wider track width. The light forged rims are optionally available in 20 and 22 inch. In addition, the colour of the wheel spider and wheel base can be selected individually. Good to know: the 295 series tyres can still be used on 20-inch GME rims.

Finally, the original, electronically adjustable Bilstein suspension with self-developed sports springs was lowered by 15mm (front) and 30mm (rear). An individually adjustable sports suspension from GME is available on request.

For all those who want even more power, further power stages between 850 and 1000 HP are in progress.
