15 TurboSmart also supplied one of their RacePort blow off valves. A high-flow blow off valve is a necessity on high-boost/power applications. The blow off valve opened to provide pressure relief during shifts or lift-throttle applications. Without the valve, the pressure wave that flows back after slamming into the closed throttle body would try to escape back out the turbo. Attempting to instantaneously stop or reverse the flow of an impeller spinning upwards of 100,000 rpm is not a good situation! The RacePort shared the threaded collar design with the new Hypergates.
