The madmen at True Street Performance in New York have created a monster. They got a little too anxious for the upcoming Jeep Grand Cherokee Trackhawk that’s coming out later this year, so they stuffed a Hellcat-sourced 707 horsepower Hemi V8 into an all-wheel drive WK Grand Cherokee from the mid-late 2000s. Here it is obliterating a dyno:
It sounds like the HellhaWK happened almost by accident. “We had an extra motor and a donor body we were trying to decide what to do with… and came up with putting them together,” shop owner Jim told Jalopnik. The idea began with a customer asking if they could make a custom Jeep Hellcat, so they put this one together to see how it would turn out. Here’s how it turned out.

According to a Facebook post, this beast had an even better run doing 10.5 seconds at 132 mph.
Upgrades other than the engine swap include a Paramount Performance transmission, stronger axles, and a new differential. The transfer case is stock and clearly has no problem handling this much power—at least not yet.
Jim indicated that the cost for a build like this would cost around $40-50,000. Not too bad for an SUV that can hustle the quarter mile in 10.5 seconds.
So, if you’re looking for a more budget-friendly alternative to the all-new Trackhawk, and if you really need to get home from the mall in a hurry, True Street Performance is here to help.
