Go Fast Bits SV50: A rugged and reliable blow off valve rated at over 300 PSI
The massive flow capacity of the SV50 makes it suitable for high-powered turbo or supercharged engines, whilst the ability to adjust the spring pre-load ensures it can be fine-tuned with far more precision than by swapping springs as our competitors do. The supplied hinged billet v-band clamp is easier to install and stronger than other flexible band-clamp designs, yet it is compatible with other commonly used weld-on flanges. This means the SV50 is a direct fit if your piping is already fitted with a TiAl flange.; 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.
