All fixed geometry PowerMax units utilize the Garrett® GT ball bearing technology, featuring advanced GT Series wheel designs that ensure top performance, lower back pressure, and offer reduced intake/exhaust gas temperatures for quicker spool-up. Read More...
PowerMax AVNT turbochargers utilize nine moveable vanes which significantly increase turbine efficiency and improve engine performance from launch through peak torque. Read More...
The higher air flow and efficiency of PowerMax provides more air flow than the stock turbo thereby maximizing combustion efficiency and power when applied with other engine modifications that increase fuel delivery. Excessive black smoke in the exhaust is wasted power from unburned fuel. PowerMax delivers the increased air flow required for high performance diesel engines. Click your application below to see how PowerMax can give your diesel the boost it needs.
The GM Duramax application for PowerMax is specially matched to optimize increased air flow when applied with electronic fuel flow modules.
