Our X3 Turbo Blow-Off Valve is CNC machined from a billet aluminum slug. After tolerances are verified, the piston and body are Teflon coated. Extreme temperature Viton sealing O-Rings are used for long service life. Our BOV's are designed specifically for offroad, small displacement engines and not adapted from larger road use vehicles. You won't find anyone else in the powersports industry that designs BOV's specifically for each vehicle. A custom fitted filter is also included with every kit to keep dirt and debris out of the BOV outlet ports. Billet aluminum, Teflon coated construction with high temperature Viton sealing O-Rings Has the "Blow-Off Valve" sound that turbo customers crave Tested to 500 horsepower Simple install - No drilling required Requires the EVP silicone charge tube set with integrated BOV port Includes a pre filter to keep dirt/sand out of the valve exhaust ports High performance turbo systems require a BOV when running higher than stock boost pressures. The reason is turbochargers continue to force air into the charge tubes and intercooler even after you lift off the pedal (which closes the throttle). Pumping air against a closed throttle super heats the air in the charge tubes and is damaging to the turbocharger bearing system. Installing a BOV allows this pressure to be released upon the closing of the throttle which increases throttle response in on/off/on throttle conditions by venting the the hot compressed air. The Maverick X3 required extensive design and testing of various springs to get the right balance of responsiveness and performance.

Requires charge tubes with a 1" port. The EVP charge tubes have the required BOV port and are available as an option. Tested to 500 horsepower Simple install, no drilling required. The body, piston and cap are machined from billet aluminum. The cap is anodized anodized and re-machined for easy gripping for spring tension adjustments. The piston and body are hard coated with impregnated Teflon anti friction matrix. The design has 4 sealing O-rings for leak proof operation.
