Performance Highlights
- Over 765 HP and 665 lb-ft of torque on 91+ octane
- Designed specifically for Power Onboard dual alternator trucks
- Instant boost with a flat, torque-heavy powerband
- More power per pound of boost than competing systems
Gen 6x Supercharger Technology
At the heart of the system is the Gen 6x W185RF 3.0L Whipple twin-screw supercharger, featuring a redesigned housing, inlet, and pulley system for improved airflow efficiency. The exclusive 3x4 rotor pack increases RPM capacity while minimizing leak paths, delivering stronger airflow under the curve and cooler discharge temperatures.
The massive Crusher 150mm inlet dramatically reduces restriction and rotor cavitation, allowing the engine to make more power at lower boost levelsideal for pump-gas reliability and long-term durability.
Industry-Leading Intercooling
Whipples patented dual-pass, dual-core intercooler system is unmatched in the industry. Each intercooler core is utilized twice, effectively doubling the cooling surface area without increasing packaging size. The result is dramatically lower intake air temperatures and resistance to heat soak under sustained load.
Paired with the largest dual-pass heat exchanger on the market and a high-flow intercooler pump, this system delivers consistent, repeatable power whether towing, daily driving, or wide-open throttle.
Fueling, Calibration & Control
The Stage 1R Dual Alternator kit includes GT500 Bosch dual-beam fuel injectors to safely support increased airflow and power. Calibration is handled through the included Whipple Tomahawk V2 flash tool, giving you:
- Emissions-compliant Whipple PCM calibration
- Ability to read and clear diagnostic trouble codes
- Wheel, tire, and axle ratio calibration support
- Retention of factory drive modes and transmission behavior
