Blow Off Valves
That whoosh between gears has sold more turbo cars than any spec sheet ever will. Beyond the soundtrack though, a quality blow-off valve does a real job, venting charge pressure on throttle lift to protect your turbo and keep boost response sharp.
At Pro Speed Racing, we help enthusiasts find blow-off valves from Turbosmart, GFB, HKS and other proven brands, in atmospheric, recirculating and dual-port configurations to suit your setup and your tune. Factory valves leak under raised boost and give up early, so a proper valve is one of the first upgrades any boosted build deserves.
We do not store every valve on hand, but our sourcing network gives you access to genuine product direct from the supply chain. If you need a specific configuration, spring rate or platform fitment, Pro Speed Racing can help source the right gear.
Why Upgrade Your Blow-Off Valve?
- Holds boost reliably where factory valves leak
- Faster valve response between gear changes
- Choice of full atmo sound or quiet recirc
- Protects your turbo from compressor surge
- Adjustable spring pressure to match your boost level
- Direct-fit and universal options across brands
Find The Right BOV For Your Car
Add your vehicle to our Garage Function and it will filter every valve made for your platform.
No guessing, no adapter-stacking to make a universal valve behave, and no ordering atmo when your tune wants recirc. Just direct fitment and the sound you're after, first time.

The atmo-versus-recirc question deserves a straight answer, and it depends on your car. MAF-based cars generally want recirculated air to keep fuelling accurate, while MAP-based setups can vent to atmosphere freely, and dual-port valves give you a foot in both camps.
Beyond configuration, valve quality shows up under pressure. Billet bodies, precise machining and adjustable springs mean the valve holds boost at your target, opens exactly when it should, and keeps doing both years after a factory valve would have retired.
