The testing we performed was back-to-back without tuning changes for power. — Dustin Whipple, Whipple Superchargers
The company performed a direct-swap from its Gen 2 generation to the new Gen 3 on a customer’s Terminator, and the result was a gain of nearly 100 horsepower and 100 lb-ft of torque at the rear wheels. What’s more impressive about those results is that the fuel type (E85) and boost level (21 psi) were not changed, proving that the all-new Gen 3 supercharger is as efficient as they come.

See those under-the-curve gains? The all-new Gen 3 supercharger starts making that 100-plus horsepower and lb-ft of torque at just 3,500 rpm.
“The testing we performed was back-to-back without tuning changes for power,” Dustin Whipple, of Whipple Superchargers, said. “It did require an updated tune though, as the owner of the Cobra wanted to install larger fuel injectors. However, timing and the air/fuel ratio were not modified.”
Dustin said that the Gen-3 supercharger’s success can be attributed to its new features, such as precision-cut rotors, upgraded coating techniques, revised ports and an updated inlet shape – all of which increase’s the Gen-3’s total efficiency.

Externally, the Gen 3 2.9-liter Whipple supercharger is much different than the previous generation. The external ribbing on the case does not extend up to the inlet like previous versions.
“What this translates to is significantly more power at the same boost level,” he explained. “The increased efficiency results in reduced power consumption and lower temperatures.”
What that equates to is a standard gain between 30 and 40 horsepower at the rear wheels, and Whipple has witnessed as much as 150 rear-wheel horsepower on highly modified applications. Whipple’s Gen 3 twin-screw supercharger boasts more displacement and greater efficiency for generating boost, so check out all of the details on its latest supercharger here for more information.
