Turbosmart's ProPort has an all new 54mm (2.13in) Blow Off Valve with a tiny footprint and massive flow. The ProPort 54mm flows 420 cfm, which is enough for 3500 HP and is in a league all of its own, standing 30mm (1.2in) lower than the PowerPort while flowing over 25% more than the market leading 50mm RacePort. Features include our unique locking collar design, new unique vent profile, sensor cap option and spring options for all turbocharged applications.

The ProPort 54mm resulted from over 25 years of Blow Off Valve Manufacturing experience and 12 months of internal development. The design is CFD driven and real-world validated for the maximum possible flow based on the demands of the Tuning and Motorsport market. The Milspec Diaphragm operated valve is highly responsive while using our Boost-Balanced system, which means the more boost you feed it, the better it seals!

Available with an onboard position sensor as an option, we utilize a non-contact hall effect sensor for the position of the valve, which means no through-holes in the cap, ensuring no chance of leaks. The data this can provide for professional and amateur teams alike is invaluable when every pass and every minute on the track counts!

The Quick Release V-Band system is of the quality you expect from Turbosmart. Our GenV cap profile is easily distinguishable and includes 2 x 1/8 NPT refernce ports. The cap can be rotated for simplifying refernce hose runs in complex engine bays.
