Turbosmart TS-0203-1022 Kompact 25 mm Dual Port Universal Fit Blow Off Valve , Black

I used this on my 2010 Jeep Wrangler Unlimited - I added the Ripp Supercharger. I changed to the altitude pulley and was able to adjust the firmness of the valve just the way I like it. Before the plastic BOV ( the one it came with ) slightly leaked all the time and did not build the boost I knew was there. After, with the Turbosmart, I was able to get 12.1 LBS max and much more consistent drivability.Would fully recommend for my application.

Works great on my Jackson Racing Rotrex C30 Supercharger for my 2013 Scion FR-S, have to have the adjustment pretty much as soft as possible though for it to work, port vacuum is pretty weak on these cars.Sounds amazing, and improves throttle response if adjusted properly..https://www.youtube.com/watch?v=YQhvEtyNW8w

Works great!

Used this valve to replace the HD valve from IPD that failed and in the end damaged my engine on my Volvo s60r. So much better and sounds great. Full boost has returned and power is back. Had to replace the engine though.

Love the sound it makes with my supercharger. (Belt driven turbo)

Perfect as described! Loud and Proud!

Bought this to replace the original plastic BOV that came with my Ripp supercharger. Works great and love that it's adjustable. this thing will not be failing the way the Bosch ones did.

I bought this to replace a leaking Bosche bypass valve. The quality is impressive and the ease of adjustment is a huge benefit. I was able to dial in the boost on my Jeep to bring back a nice smooth idle with no surging while holding max 11psi at wide open throttle.

Used on my ripped jeep jk. Comes with a pink spring which is a too stiff for the supercharged application. Ended up buying the softer blue spring
