The relief valve is supplied with an oversized 1/4" Pneufit quick connector for a 6mm hard pipe. This is used to connect the relief valve to the vacuum in the intake manifold. Additional hose and nipple connections are available as accessories.
What is a relief valve for and how does it work?
A bleed valve is actually a pressure relief valve that bleeds off turbo pressure/boost pressure when the throttle is closed. While the turbo is still spinning and producing pressure, when the throttle is closed, a pressure wave is sent back to the turbocharger, causing the compressor wheel to stall the "supercharger surge" and slow it down very quickly.
A relief valve is installed between the turbocharger and the throttle valve, which is connected to the vacuum.
A well-sized blow-off valve increases the life of the turbo and is necessary for its functionality.
