Turbosmart Race Port Series Blow-Off Valve

A Lighter, Smaller, and More Efficient Blow Off Valve

The largest and the highest-flowing BOV in the Turbosmart range has just been redesigned and now features a unique collar design. These BOV's are 46% lighter and 25% smaller than the product it replaces. The new Race Port provides greater performance through faster turbo spool-up from idle and reduced turbo lag between gears. Ideal for large capacity turbocharger systems and high horsepower engines.
