Features
- Patent Pending
- XBoost Technology increases power and performance
- Up to +29% compressor flow compared to G-Series (Depending on model and frame size)
- Improved pressure ratio capability enables higher boost pressure
- Increased efficiency at high flow rates provides cooler, denser air to boost power capability
