Performance & Application
The G45-1350 is designed for builds targeting massive horsepower while retaining strong turbine-side response through its divided T4 housing configuration. Its 72mm compressor inducer and 51 trim wheel work with the 0.85 A/R compressor housing to deliver high-flow capability at the top end of the power curve. On the exhaust side, the 89mm turbine inducer and 84 trim wheel are matched to the 1.28 A/R divided turbine housing for aggressive spool characteristics. This configuration is built for high-horsepower applications where both spool quality and sustained top-end flow are critical.
