BIG HP Blow-off Valve
Introducing the GFB SV45 - The BIGGEST addition to our extensive range, designed specifically for drag racing and big horsepower engines.

The most important feature of this valve is its unique flow path, which has proven capable of flowing enough for engines pushing over 1200hp!

sv45-1The large 45mm piston has a contoured lead-in to smoothly spread the air to the outlets, which are flared and matched to the piston shape for the smoothest flow path of any valve on the market!

The ball-style attachment method is unique, strong, and easy to use. Five chrome steel balls locate into mating pockets on the weld-on adaptor, and are locked into place by the knurled ring. No tools are necessary to fit or remove the valve, it is as simple and secure as an air hose connection.

The SV45 comes with two nested springs to allow the spring pre-load to be easily tailored to suit a wide range of idle vacuum ranges.
