Designed to cope with the brutal conditions of extreme exhaust temperatures, the EX50 features not only a huge flow capacity, but also a compact size that is unmatched by competitors for a 50mm wastegate.

• Supplied with a 13psi spring
• 7psi and 9psi springs also available that can be ganged together with the supplied 13psi spring in various combinations to allow boost pressures of 7, 9, 13, 16, 20, 22 and 29psi.
• V-band clamp mounting system, supplied with 304 stainless weld-on adaptors (base flange is compatible with TiAl 44 flange when used with GFB adaptor)

Take note - the SV50 has the strength to withstand over 300psi without breaking a sweat! Try doing this with a diaphragm-type BOV! The SV50’s single-piece billet monoblock body design eliminates the need for fasteners and a separate cap, making it stronger and more compact. The one-piece brass piston does not use a diaphragm. This ensures strength and reliability for the life of the valve. Other brands require you to pay extra for different springs to set the valve up to the engine’s idle vacuum. The SV50 can be used on applications with manifold vacuum ranging from 5-22”Hg (2.5-11psi vacuum).
