Jeep’s Hellcat powered Grand Cherokee is expected to go into production this summer, but one owner couldn’t wait for the Trackhawk and decided to get a supercharged Grand Cherokee SRT built for him.
It may not be carrying a Hellcat engine under its hood, but the SRT can crank out 713 whp or an estimated 800 hp. The large bump in power comes from a Whipple supercharger, Corsa catback exhaust, American Racing exhaust headers, Boost cam, and a built motor.
Currently, the supercharger works at 13 PSI and the owner is looking to install an E85 setup to increase that number to 15 PSI. Doing so could bump up the machine’s wheel horsepower to 900 when using 93 Octane gas. With racing fuel, the HEMI may be able to hit 1000 hp! That’s a lot of power and we can even see the rear tires smoke a bit during the SRT’s takeoff in the video.
Along with the performance upgrade, this SRT owner has made some exterior changes as well including a Renegade spoiler, painted mud guards, roof wrap, front splitter, chrome delete, Rennen forged wheels, custom quad exhaust tips and more.
There’s still have a year before the Trackhawk goes into production, maybe some other GC enthusiasts will modify their current vehicle to avoid the wait.
