High Performance Blow Off Valve

Application: Supercharged and Turbocharged Systems Running High Boost Pressures

Description: Some blow off valves can be forced open by high pressure, so they leak boost away instead of sending it to your motor. This blow off valve is specifically designed to handle up to 24 pounds of boost and stay shut, so you get all the HP that you paid for!

The big, 1 inch inlets and outlets will tame even the largest blowers, and its machined from solid aluminum billet so you won't find it cracking and breaking under the pressure. A handsome addition to any proud engine presentation.

Yes, you can get a cute little "whistler" BOV on eBay for a lot less - but this is no toy. This is the big boy BOV for serious boosted applications.

Availability: Normally in stock, and if we run out of stock we can have more in 3 days or less.
