The Forge RS valve has been specifically designed and engineered, to offer extreme flow rate capability, where other valves are just not up to it. Often when engines have been tuned by installing larger turbos or even software upgrades improved turbo response can be acheived by fitting the RS valve which has the greater internal [...]
Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the “Whoosh” sound most commonly associated with rally cars. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.Dual-Piston Atmospheric Valves and Valve Fitting Kits
All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built [...]
Made from billet aluminium, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.Available in Polished only.

Inefficient factory blow off valves (BOV) can hinder boost response during shifts and can damage your expensive turbo charger. PERRIN™ offers several choices for owners to choose the best solution to the problem.
Fully recirculated (Recirc shown) For clients that demand proper air fuel ratios and idle quality we offer a fully recirculated BOV. The [...]
Agency Power turn to its design team to produce the first multi function and fully adjustable Blow Off Valve for the VW, Audi, and other vehicles using a 1 inch inlet and outlet flanges. Keeping the turbo spooled between shifts, holding boost pressure strong, and giving you adjustability is what the all new Agency Power [...]
For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.98 in (50.5mm) valve; we believe this is the largest valve available with the highest flow capacity.The V-Band design aluminum mounting clamp gives a very [...]

Identical in design to our RBV-H34 with the exception that the outlet of the valve is our standard Type H female inlet instead of a 34mm hose adapter. This allows the valve to be used either in normal fashion or “reversed”. Using the valve in the reversed orientation ensure that the valve will only open [...]
With new and improved styling, the BOV-H-RFL remains true to it’s roots - it’s still really f’n loud! Like all our valves, the RFL relieves compressor pressure surge caused by changing gears or backing off the throttle and has been used on turbo charged engines running upto 35 psi boost. If you need to ask [...]
