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" 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" 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).
