Performance & Application

The G25-700 G-Series II utilizes Gen I compressor and turbine housings while incorporating new compressor aero technology that increases both power and performance. Compared to the original G-Series Gen I, this unit delivers up to 10% higher compressor flow at peak pressure ratio and peak turbo RPM, along with increased efficiency at high flow rates. Calibration is required to fully take advantage of this increased flow for a horsepower upgrade. This platform serves as a direct upgrade path for existing Gen I customers, available as a complete turbo unit, supercore, or CHRA-only purchase.
