SV52 (52.5mm) Universal

In the race to create the most compact and highest flowing blow-off valve, GFB’s SV52 pulls ahead of the pack.
Standing only 86mm tall (including the weld-on adaptor), the SV52 is 10mm shorter than the nearest competitor, AND flows more!
Consider these questions when you’re looking for a BOV for your high-powered, forced induction engine:

Will it handle the pressure?…………………………….. YES! Is 300psi enough?
Will it flow enough?………………………………………… YES! It outflows everything else in its class!
Is it small enough to fit my engine bay?…………..YES! 10mm shorter than the nearest competitor!
Will it last?…………………………………………………………. YES! It comes with a lifetime warranty!
Strength is important;

Realizing that a high-flowing valve like this will see duty in some high-boost environments, we made sure the SV52 tops the class in that category as well, giving it an astonishing boost pressure rating of 300psi!

The SV52 also includes 2 springs PLUS a spring pre-load adjustment system so you can dial it in for optimum throttle response and boost recovery after gearshift, without resorting to the costly hit- and-miss approach of purchasing extra springs.

**Suits engines with manifold vacuum ranging from 5-22inHg (17-74.5kPa, 2.5-11psi vacuum)
