Whipple Gen-3 Rotor Upgrade for the 2.9L Twin Screw Supercharger

Our friends over at Lethal Performance shared the following information about their New Exclusive Gen-3 Rotor Upgrade for the Whipple 2.9L Twin Screw Supercharger. This upgrade kit sounds like exactly what the twin-screw market has been looking for, and it's going to be very interesting to see how far early adopters will be able to push the performance envelope. Best of all, if you were thinking about pulling the trigger on a new Whipple kit you can get the Gen-3 upgrade for a mere $200 extra. That's a no-brainer in my book. Check out the full details below, and give Lethal Performance a call ordering details.


- Adds up to 30-150 hp/tq at the same boost level

- 10-80*F cooler temps

- New Whipple Crusher SC Housing for increased volumetric efficiency

- Simple bolt-on upgrade to existing Gen 1 and Gen 2 2.9L/W175AXFF superchargers

- $200 add-on upgrade if ordering a complete kit

Whipple Superchargers, known for years of innovation, have now developed the new Gen 3 Whipple 2.9L supercharger that features both updated rotor design and rotor housing to unleash even more power from your engine. The Gen 3 works with nearly all 2.9L Gen 1 and 2 applications and is a simple upper half swap. No tuning required, just more power by increased supercharger efficiency.

Gen 3 features all new 3/5 rotors that feature a new updated rotor profile and new advanced manufacturing methods, allowing more accurate and tighter tolerances along with increased efficiency. Each Gen 3 rotor also features a later generation robotically sprayed conformal rotor coating, allowing the rotor clearance to conform to the operating conditions and application. The Gen 3 also features upgraded double lip PTFE rotor seals for higher RPM, higher temp and higher pressure ratios.

The Gen 3 also features a new rotor housing with the new angled support ribs for a more aggressive appearance, along with revised port shape for increased rotor filling and decreased turbulence, resulting in increased overall supercharger efficiency. What does all this mean? More power, more power, more power while maintaining the same boost levels.

During extensive testing on multiple applications, both Whipple and 3rd party testing found gains from 30RWHP up to 150RWHP depending on blower speed and engine specifications. Standard pump gas applications can easily make another 30RWHP with no other changes. Because boost maintains, tuning is not required. Just bolt on and unleash the power of your stock application.

Each swap kit comes with all the necessary parts/hardware to swap the Gen 2 SC for the Gen 3. No cutting or grinding required.

Current available applications:
