Spring RacePort 0.51 bar (Old Style)

Turbosmart RacePort Spring 0.51 bar (Old Model)

Turbosmart is a leading Australian manufacturer specializing in turbo engine tuning, active since 1997 under the motto "Engineered to Win." A long-standing specialist in dump valves (blow-off valves), the brand designs, machines, and tests its products in-house to guarantee reliability, sealing, and performance.

According to Turbosmart, the RacePort is the highest-performing dump valve on the market in the 50 mm segment, thanks to an internal geometry that moves more air than competitors of the same apparent diameter, while remaining the lightest and most compact in its category, a decisive advantage in competition. V-Band mounting for secure fitment and quick removal during races. Available in VTA (atmospheric vent), Plumb Back (recirculating, popular off-road), EM (electromechanical, electronic boost management), and female-flange (compatible with existing competitor flanges) versions. It supports up to around 1,500 hp and covers the vast majority of high-performance applications.

Turbosmart replacement spring for previous-generation RacePort dump valves (old model), 0.51 bar preload. The spring sets the piston preload, the pressure at which the valve opens and closes.

A spring matched to your boost level ensures a perfect hold at idle and a crisp opening on lift-off. This 0.51 bar rate suits moderate-to-sustained boost builds.
