RIPP Supercharger


  • Available for your 07-11 and 12-16 JK
  • Initial testing has found that in stock form the 3.8l only produces 133 Wheel Horse Power (WHP) on stock tires and gears. Most of our clients have 35-37" tires installed, WHP then drops to 108-123whp.

    With the addition of  a RIPP Supercharger and running through stock exhaust manifolds, cats and exhaust, the 3.8l produces 240-/+ Rear Wheel HP (WHP) on stock wheels/tires and gears at 8psi. More over an impressive **230+whp and 260+lb/ft of torque on commonly used 35" wheels and tires.

    Automatic : Stock 133whp
    RIPP Supercharged 240whp (Measured at the rear wheels)*

    Manual : Stock 149whp
    RIPP Supercharged 260whp

  • Preliminary tests show an Automatic 3.6 Pentastar Jeep Wrangler Unlimited produces only 189 rear wheel HP (WHP) in stock form. With larger wheels and tires, like most clients have, power is even lower. With a RIPP Supercharger installed we safely squeezed 325WHP and 300ft/lbs** of Torque on 37in tall tires. That WHP is higher than a 5.7 V8 Engine swap costing thousands more and more in line with a 6.4 Hemi swap. Additionally clients have reported an MPG increase from 1-4mpg combined City/hwy
