GFB Go Fast Bits T9052 SV52 Blow Off Valve Diverter Valve Weld-On

The GFB SV52 blow off valve (BOV), also called a diverter valve, is a compact, high-flow valve for turbocharged and supercharged engines. This version, T9052, is the model with the weld-on adaptor. GFB built it to flow more while taking up less space in the engine bay.

With the weld-on adaptor included, the SV52 stands only 86mm tall. That is 10mm shorter than the nearest competitor, according to GFB.

Key Features:

• Rated for boost pressure of 300psi
• Monobloc body, CNC machined from a single billet of aluminium
• Anodized piston bore with a single-piece aluminum 52.5mm piston
• Viton o-ring seals in an arrangement unique to GFB
• Supplied with 2 springs and a spring pre-load adjustment system
• Weld-on 6061-T6 aluminium base that welds to the charge piping
• Mounts without a v-band, which lets the piston and venting ports sit lower and reduces overall height
• Suits engines with manifold vacuum from 5 to 22inHg

Install the valve between the throttle body and the intercooler if you can, away from direct heat sources. The vacuum port should connect directly to the intake manifold with the shortest hose possible. If the valve must sit near exhaust components, protect it with heat shielding.
