Initial testing has found that in stock form the 3.8L only produces as little as 133 Wheel Horse Power (WHP) on stock wheels/tires and gears and as little as 108-123whp on up rated 35 inch tires. 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 240+whp and 260+lb/ft of torque on commonly used 35 inch wheels and tires. (HP levels vary depending on tire and gear combination as rotational mass comes into play, this effects both Naturally Aspirated (NA) and Forced Induction (FI) total output). Four ply silicon hose - Black. RIPP PCV valve. All hardware and clamps included. Illustrated instructions and tech tips. 1 year warranty.

Q: The 5.7 supercharger kit for wk2 jeep grand Cherokee. the 8speed tranny is rated for 516 ft/lb. of torque. How much torque will this supercharger add to the 390 stock? Answer this question
A: Per Ripp: The 5.7 does a good job power wise, but can always use a little more. When tested on our dyno it produced 280 All Wheel HP (whp) which in our opinion is de-tuned and capable of so much more. https://www.rippmods.com/products/2011-2014-grand-cherokee-supercharger-5-7?_pos=1&_sid=593375dea&_ss=r
