GFB SV50 High Flow BOV - Rated at Over 300psi (Suits All High Powered Turbo or Supercharged Engines)

GFB's SV50 is built tough. Tough enough to handle immense boost pressure ? over 300 psi ? more boost than 13 stock Mitsubishi Evo Xs combined! There is no chance of rupturing the diaphragm, because it doesn't use one. Unlike our competitors, the piston runs in a precision machined and anodized bore that doesn't require a diaphragm. Why did we do this? Diaphragms are only designed to hold pressure on one side, but in a BOV they are exposed to both boost pressure and manifold vacuum. Boost pressure collapses the diaphragm on itself, which weakens the fabric reinforcing material, and the abrasion of the diaphragm walls rubbing on itself can eventually cause failure. The SV50's piston and bore on the other hand will last a lifetime, and will take any kind of abuse you can throw at it. HIGHEST FLOWING BLOW-OFF VALVE TO SUPPORT IMMENSE HORSEPOWER! The SV50?s piston and bore will last a lifetime, and will take any kind of abuse you can throw at it.
