The Gen 5 3.8L Whipple Supercharger will carry similar features to the 3.0L Whipple. It has all new bearings, gears, rotors and housing that allow the new supercharger to spin faster, longer and safer while producing more power than any other positive displacement supercharger ever built.

Compared to itís little sibling, the 3.8L supercharger will have an improved rotor profile, increased volume, improved sealing and increased efficiency. The 3.8L will also feature a new inlet design that is 2 pieces, allowing easier access for the rear bolts, your spark plugs and other items that previous models made difficult to access.

When looking at side-by-side photos of the housings and rotors of both the 3.0L and 3.8L Whipple superchargers, you can see that the designs are similar except for the fact that the 3.8L is much larger. Also, compared to the larger volume 4.0L, the 3.8L is slightly taller however it is roughly 60mm shorter (just over 2 inches), giving it some serious girth while not taking out your firewall in the process.

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
