This might look like an ordinary Jeep Grand Cherokee, but with a uniquely located turbo (underneath the transmission) courtesy of John Hennessey, it’s now a Super Cherokee. Though Hennessey was just featured on DYH’s Tuner Tuesday for his 1000hp Viper, it’s hard to not give him a repeat showing with vehicles like this. The $27,900 SRT600 package turns an already powerful 420hp V8 into a ridiculously powerful 620hp monster, complete with a two year warranty. Seeing as the Jeep already pulls a .9 on the skidpad, has four wheel drive, and comes with all of the luxury any SUV owner could desire, Hennessey kept things simple and focused on the engine. Upgrades include:
- Forged Pistons (9.5:1 compression ratio)
- Forged Steel Connecting Rods
- Ported & Polished Cylinder Heads
- Balanced & Blueprinted Assembly
- Single Turbocharger
- Stainless Steel Turbo Headers
- Single 44 mm Wastegate
- Stainless Steel Dual 3 in. Exhaust System with Polished 4 in. Stainless Steel Exhaust Tips
- Front Mounted Air-to-Air Intercooler
- 3.5 in. Polished Inlet Tube with Blow-Off Valve
- Upgraded Fuel Pump & Fuel System
So what does all that give you? How about:
- 0 – 60 mph: 3.5 seconds
- 0 – 100 mph: 8.9 seconds
- 1/4 mile: 11.9 seconds @ 116 mph
Just to put that in perspective, your Hennessey powered grocery getter will now beat a Porsche Cayenne Turbo S in the quarter by more than a second. But the Cayenne is just another SUV, what about cars? Glad you asked. The SRT600 will also win in a quarter mile drag if you go against any of the BMW M cars, all of the Mercedes AMG cars except for the SL65, the Audi S6, the Corvette, the Porsche 911 S, and even the Lamborghini Gallardo. The only cars that manage to best the beast are the 911 Turbo and the Corvette Z06, though they only manage to do it by a half of a second (and their trunks are just about big enough for a pair of swim trunks).
Fast is good.
