Running 9 seconds in the quarter mile is quite a feat for any sports car. It takes come serious modifications to get a Toyota Supra or Chevy Corvette to go that fast. And just recently we reported on the first Nissan GT-R to break the 10 second barrier. So imagine how surprised we were to hear of a 9-second SUV. That’s right, a Jeep SRT8 has gone down the quarter mile with the quickest time of 9.658 and the fastest mph of 146.72.

The high performance version of Jeep’s Grand Cherokee, the SRT-8 sports a 6.1-liter Hemi V8 that pushes out 420-hp and 420 ft-lbs of torque from the factory. Stock 0-60 is under five seconds with a top speed of 150-mph. But hey, that means absolutely nothing for this SRT-8 that’s pushing close to the factory top speed in less than 10 seconds and in a mere quarter of a mile.

Built by Lewis Performance Machine, the SRT-8 sports a 426-stroker built to handle 1500 AWD horsepower. Details are naturally a little hard to find, but the owner reports the obvious: upgraded fuel system, drive line and rear end. He does let the public know that a 75-shot of NOS is used to help get the Jeep off the line while the trans brake and 2-step is still being tested. The beast is tuned by Johan at Diablo and rolls on Nitto NT05Rs on the stock rims.

The video after the jump shows the SRT-8 running a 9.87, which the owner claims is on 13 psi and the 75 shot. The 9.659 was with 16 psi and the 9.658 was at 19 psi with the boost tube blowing off. Naturally the Jeep SRT-8 had a lot more in it, given that its 9.658 pass was at a lowly 139.36 mph vs the 146.72 it hit with the 9.659 pass.

It should only be a matter of time before the SRT-8 hits Orlando Speedworld again, so we’ll keep you guys up to date if they enter the record books with an 8 second pass.

Make sure you check out the video after the break!

The Mopar performance department at Chrysler went all out in building the Mopar Jeep Lower Forty, which is designed to deliver serious off-roading – just the way Jeep drivers like it. Starting life as a two-door Jeep Wrangler Rubicon, the gear-heads at Mopar decided to add on a set of 20-inch Mopar wheels and 40-inch tires, while keeping the car’s center of gravity as close to stock as possible. In order to do so, some serious body modifications were necessary, including moving much of the chassis higher into the vehicle. As a result, almost three inches had to be removed from the windshield, while the one-inch wider fender flares now sit 4-inches higher.

But the modifications didn’t stop there. Under a carbon fiber hood sits a 5.7-liter HEMI V8 and a Getrag six-speed manual transmission. To get all that power to the ground are new front and rear axles with 5.38 gears and ARB air lockers.

Other highlights include an integrated roll cage and in place of carpeting, the Mopar guys opted for a spray-in truck bed liner.
