What is the main benefit of a Dual Port blow-off valve?

A Dual Port blow-off valve offers a balance between performance and quiet operation. It vents some boost to the atmosphere for sound and turbo protection, while recirculating other boost back into the intake to reduce noise during everyday driving.

Can I change the operation of this Turbosmart BOV?

Yes, this Kompact Dual Port valve is designed for flexibility. It includes a port blanking plug that allows you to convert it into a full atmospheric vent or a full bypass unit, depending on your preference or tuning needs.

What does 'Not CARB approved' mean for this part?

This means the blow-off valve does not meet the emissions standards set by the California Air Resources Board (CARB). As a result, it cannot be legally sold or shipped to California.

Product Details

Turbosmart is well-known for making solid performance parts for turbocharged vehicles. This Kompact Dual Port blow-off valve, part number TS-0203-1023, is a great example of their approach to forced induction tuning. It's designed to manage boost pressure effectively, helping to protect your turbocharger from damage caused by compressor surge when you let off the throttle.

What makes this Dual Port unit interesting is its ability to vent boost both to the atmosphere and back into the intake system. The ports operate with sequential timing, meaning it acts more like a recirculating bypass valve during normal, light-throttle driving for quieter operation. But when you're really pushing it, it opens up to vent to the atmosphere, giving you that satisfying blow-off sound and all the performance benefits of a vent-to-atmosphere valve. This gives you a nice balance between stealth and performance.

You can easily change how this valve operates. It comes with a plug so you can convert it to a full atmospheric vent or a full bypass unit if your needs change. Just a heads-up, this part is not CARB approved and cannot be shipped to California. It's a well-built piece that offers a lot of flexibility for tuning your turbocharged vehicle.
