	Go Fast Bits Basic Dump Valve FD3S Basic by name but not by quality. Sporting the same unique internal features and quality found in all GFB valves, tests prove that the Basic can flow up to 40% more than other valves on the market of the same size and shape. This is actually one of the highest flowing valves in the GFB range owing to the large venting area of the 5 hole pattern. This capacity makes the basic a great choice for big horsepower and drag engines and all at an affordable price.

	Apex-I Twin Chamber Blow Off Valve Twin Chamber Blow Off Valve utilizes a revolutionary new Dual Chamber design engineered for high and low boost response. On turbocharged vehicles, Blow Off Valves release excessive boost pressure trapped inside the intake pipe when the throttle is released. This release of pressure is important because as the vehicle accelerates, the turbo builds a high pressure air stream through the throttle body and into the motor. When the driver lets off of the accelerator and closes the throttle plate, the trapped air instantaneously has nowhere to go. This trapped air begins to travel back towards the turbine blade causing excessive strain on the blades. Prolonged exposure to these conditions can cause premature turbine wear and eventually cause turbine failure. The A’PEXi Twin Chamber Blow Off is designed to effectively release this pressure into the atmosphere. The unique twin chamber design allows quick response without causing any excessive turbo lag between gears. The unit features 3 point sound adjustment and a spring tension adjusting screw. The piston sits inside top chamber for reduced wear and a valve sits in bottom chamber using the assisting vacuum hose to release excess pressure. The valve is capable of up to 2 kg/cm2 (29.4 PSI) of boost and is housed in a high finish aluminum housing. From street to race applications, it is no wonder why the Twin Chamber Blow Off valve can be seen in many of today's high power performance vehicles. Price: £228.99
