For a BOV to work consistently and not leak, tolerances must be held to an extremely high standard. The EVP BOV body, cap and piston are precision CNC machined from billet aluminum with tolerances that approach within .0003". The sliding components are hard anodized and coated so the BOV will last the lifetime of the engine. For each vehicle / engine type we make BOV kits for, the spring rates are properly matched for optimum performance. 

No other BOV on the market offers the quality and fine-tuned refinement like an EVP BOV.

After years of success with our original design and because we are never satisfied when a product can be improved, we decided to build the V2 BOV.  We took all of the greatest features of the original BOV and improved in several key areas:

  • The o-ring placement was revised so that the piston seals better than the previous version. This new design eliminates the bottom o-ring that was sometimes problematic.
  • The hard anodized BOV cap is machined with deep grooves which makes it easier to grip while making fine tuning adjustments.
  • The overall aesthetics have been greatly enhanced. The vents have a chevron design which add a great appearance while providing additional support for the piston o-rings.
  • The V2 BOV has a much crisper pressure relief than the earlier version due to the improved seal on the piston body.

Evolution Powersports was first in the industry to design and produce a Blow Off Valve (BOV) specifically for small displacement factory turbocharged engines. Virtually every BOV on the market was designed for automotive applications which have different requirements in terms of spring rates and flow capacity vs a powersports engine. Back in 2015 we decided to take a no-expense-spared approach to designing a BOV specifically for the powersports market.

No other BOV on the market offers the quality and fine-tuned refinement like an EVP BOV.

      Evolution Powersports has a reputation of the utmost quality and attention to detail on every product they design. From within the industry and outside, I have heard nothing but great things about this company and my experience has been the same. If you are looking to make more reliable power this company can get you there. Both customer service and product design are top notch and they stand behind their work!

      If you truly want to build your project with the best possible parts available, buy EVO. They not only build with the best materials they test and test to make sure you are getting the performance gains they say you will but that the mods will be safe and keep the reliability of the machine as high as possible. Thanks again to both Jim and Todd. Keep it up guys!
