Performance & Application
The G25-660 Reverse Rotation combines an ultra high flow G-Series compressor wheel with an evolutionary aero G-Series turbine wheel for maximum efficiency in a compact footprint. Its Mar-M alloy turbine wheel construction is designed to withstand extreme heat, ensuring durability under sustained high-load conditions. The small frame architecture allows for quick spool response while still supporting a 660HP power ceiling, making it well suited for builds that demand both responsiveness and top-end output. This configuration is ideal for enthusiasts running reverse
