Gen 6x Whipple Supercharger Technology
At the core of the Stage 1R system is Whipples Gen 6x W185RF 3.0L twin-screw supercharger, featuring a redesigned housing, inlet, and pulley system for improved airflow and efficiency. The exclusive 3x4 rotor pack increases RPM capacity while reducing leak paths for higher efficiency across the entire rev range.
The massive Crusher 150mm inlet minimizes restriction and rotor cavitation, allowing the supercharger to deliver more airflow at lower boost levelsresulting in cooler charge temps and more usable power on pump gas.
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. This design dramatically reduces intake air temperatures and prevents heat soak under sustained load.
Paired with the largest dual-pass heat exchanger on the market and a high-flow intercooler pump, the Stage 1R system delivers consistent, repeatable performance whether youre towing, daily driving, or going wide open.
Fueling, Tuning & Control
The Stage 1R kit includes GT500 Bosch dual-beam fuel injectors to support increased airflow and power safely. Calibration is handled through the included Whipple Tomahawk V2 flash tool, allowing you to:
- Load Whipples emissions-compliant calibration
- Read and clear diagnostic trouble codes
- Adjust tire size and axle ratio
- Maintain factory drive modes and transmission behavior
