Can Am Maverick X3 EVP Billet Boost Recirculating Valve

Tax included. Shipping calculated at checkout.

This product is unavailable

The EVP Boost Recirculation Valve (BRV) was designed to improve boost response and prevent turbocharger compressor stalling on the Maverick X3 turbo.

The EVP BRV was made specifically for customers that do not want to hear the “PSSSHH” sound of a BOV or customers that ride in the mud holes, creeks where a traditional BOV can ingest water. The BRV utilizes a completely sealed closed loop system and the diverted pressure is ducted back to the inlet of the turbocharger through our included silicone hose and adapter fittings. Requires EVP Silicone Charge Tube Kit and V-Flow intake tube available here:

17-19 charge tube

17-19 V-flow tube

20+ charge tube

20+ V-flow tube

  • Precision CNC machined from billet aluminum
  • Hard anodized body and Teflon coated piston
  • Easy bolt-on kit with all required fittings, clamps, etc. included
  • Proudly machined and made in the USA

What's the Difference Between a Blow Off Valve and a Boost Recirculating Valve? 

A blow-off valve (BOV) and boost recirculating valve (BRV) are very similar mechanically and perform similar jobs; they just do it in two different ways. Both valve bodies are attached to the charge tube, and both are designed to release turbocharger pressurized air once the throttle body closes to prevent turbocharger compressor "stalling".  Both valves are also connected to a manifold vacuum / pressure port so when the throttle body closes, the manifold vacuum pulls the BRV/BOV piston open and when the throttle blade opens and the manifold sees positive pressure, the piston of the BOV/BRV valve closes.  When the BRV valve is open, the built-up pressure in the charge air system gets diverted back to the fresh air side of the turbocharger and helps to keep the turbocharger spooled up when the throttle is being modulated from part throttle to wide open throttle then back to part throttle.  This makes the boost response crisper in these throttle modulation situations. A BOV is operated the same way but instead of venting the built-up pressure back to the turbo inlet, a BOV vents most of this pressurized air to the atmosphere and the notorious “Pssshh” sound is emitted.
