SV52 Blow Off Valve by Go Fast Bits. 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!

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.

Features:

• Handles up to 300PSI pressure
• Suits engines with manifold vacuum ranging from 5-22inHg (17-74.5kPa, 2.5-11psi vacuum)
• Outflows everything else in its class
• 10mm shorter than the nearest competitor
• Comes with a lifetime warranty
