The Evolution Powersports diverter valve (Blow off valve) is constructed of anodized billet aluminum and features very high temperature sealing o-rings. The OEM Polaris part is constructed of plastic and is a very low quality part which is prone to sticking open which will dump boost pressure to atmosphere and will cause a loss in power. The EVOPS BOV is a precision part that is designed for high performance vehicles (it has been tested to over 500 hp!) and is a direct replacement for the OEM valve. Many different spring rates have been tried to maximize the performance and fine tune the transition from where the valve is open/closed for smaller displacement turbo/supercharged vehicles.
*Direct replacement for the OEM Polaris plastic valve
*Tested to 500+ horsepower
*Billet anodized aluminum construction with high temperature sealing rings
*Does not stick like the OEM valve is prone to
For those that want to hear the blow off valve, we will be offering a different style Blow Off Valve that vents to atmosphere rather than being recirculated. It comes with a pre filter to keep dirt and debris out of it. This would not be a good option for mud guys, but for sand and fast trail, it would be the bomb. Look for this on our website next week.
