The Turbosmart PowerPort is the brand's highest-flowing blow-off valve, built to reset the flow benchmark of the popular RacePort. Its dual-chamber design supports advanced control strategies and can be held open with a solenoid to aid turbo response and launch staging for drag racing. Machined from billet 6000-series aluminum with a MILSPEC hard-anodized valve, it flows over 600 CFM through a 2.5" inlet. This black-finished valve is universal and ships with three user-configurable springs.
