861 PS !!! Hennessey Jeep Grand Cherokee Trackhawk HPE850

Earlier this year, we got the American tuner Hennessey performance his plans for those equipped with Hellcat engine Jeep Grand Cherokee Trackhawk disclosed. Targeted are over 1.000 HP and over 1.100 NM torque. And today you show that you are already on the right track because the tuner published a video on its YouTube channel that shows the off-roader with HPE850 kit. As the name suggests, the goal here is to generate at least 850 PS and the dynamometer spits out 732 PS & 888 NM at the end, probably noting "on the bike".

It was driven on Shell V-Power 93 octane fuel and ultimately that means more on the bike compared to the 136 PS & 120 NM series. With an average power loss of approx. 10-15%, the engine output should be around 840 PS and that's that Target HPE1000 Kit has come a good deal closer. By the way, Hennessey is of the opinion that it has about 20% power loss so that the 850 PS mark would even be easily cracked.

The performance is achieved by means of a new pulley for the compressor (14 PSI pressure), air intake system and an in-house chip tuning. If we get further information, also regarding the HPE1000 kit, there is of course an update for this report. You will be informed if yours is just ours Feed subscribe to.
