2008 Jeep SRT8 Build and Whipple Supercharged Shop Build by MMX / Modern Muscle Performance

Now Featuring SmoothBoost!

Come See Us on the 2019 HOTROD Power Tour!

The “Bad Penny” is our very own shop build 2008 Jeep SRT8. Sporting a 392 HEMI crate engine featuring our forged pistons and rods as well as our custom grind camshaft. This Whipple 2.9L supercharged monster is pushing 20+ lbs of boost and seeing over 1000 horsepower at all four wheels. To get that kind of power to the black top some considerable changes had to be made to the drive train of the vehicle including a beefed up transfer case built by Paramount Performance as well as their NAG1 Super Pro automotive transmission capable of supporting up to 1350HP.

From the custom fabricated air intake, the Western Differential Dana 60 in the rear, to the Cryogenic intercooler spray kit MMX / Modern Muscle Performance is pushing the envelope of what a full weight Jeep can do in the ¼ mile. All this while still maintaining the full functionality of a daily driver. So don’t be surprised to see this 9 second monster drive up to your local MOPAR car show to throw down the gauntlet!
