Polaris RZR Blow-Off Valves: Are They Worth It, And How Hard Are They To Install?

Who doesn’t love one of “mother nature's” best sounds… The sound of soothing music to any petrol head ears… The therapeutic sound that relieves stress off you, even better than fidget spinners…

That legendary sound of SUTUTUTUUU!

You know you are addicted to that heavenly sound of pure music when you rip your Polaris RZRs turbo system to the peaks, almost starting global warming with your tire burnout smoke.

Polaris RZR, installed with the best blow-off valve, has the adrenaline that runs other SXS out of breath giving them a run for their money. And no, It's not that Polaris RZRs are any less of machines without turbo systems and BOVs;

Polaris don’t make any pushovers! But installing a blow-off valve to a Polaris RZR gives it wings and transforms your ordinary RZR into a monster, ready to devour any terrain you throw at it. It's like a caged bull raring to enter the arena.

How Polaris RZR Blow-offs Valve Works

Some knowledge of the blow-off valves' nuts and bolts and functionality help you know how to maximize its functionality. Don't worry; you don't need an engineering degree for this!

Well, engineers have always intended to develop new boost tech without interfering with the top-end flow. This has its upside for side-by-side drivers, such as better fuel economy, improved low-end torque, and astounding top-end horsepower.

The turbocharger boasts more adrenaline when the boost is more than the back of the driving pressure. But this is not always the case. The driving pressure dissipates into thin air as soon as the driver moves their foot from the throttle.

Blow-off valves are installed to relieve pressure in a pipe. If the line is under pressure, air can escape from the valve and cause backflow. The backflow can occur when gas flows through the valve and into the atmosphere. This causes a negative pressure in the line, called a blow-off.

This phenomenon occurs because of the difference between atmospheric pressure and the pressure inside a closed pipe. A blow-off valve works by opening when it senses higher than atmospheric pressure in its line. Air will not flow through this valve if there is no room for it to move into or out of the valve's port; therefore, it will not open unless there is a higher pressure differential.

So, a blow-off is a type of valve that opens to vent the exhaust out of the muffler and into the atmosphere. The purpose of a blow-off is to keep it from blowing back into the engine and running down your muffler. This can cause excess heat and wear on the engine, which will shorten its lifespan.

How a Polaris RZR Improves with a Blow-off Valve

Sometimes, you need more power and torque than a stock Polaris RZR provides, and that's where the blow-off valve comes in handy!

The blow-off valve adds more power and torque to your existing engine. A BOV allows more air into the engine when it needs more airflow (especially when climbing steep slopes).

How to Install a Blow-off Valve to a Polaris RZR

The best thing about the BOV is its capability to push your RZR's performance in off-road situations, and the next best thing is its installation is not so complicated.

● With a pair of side cuts, chop off the bypass tube's bottom clamp and remove the charge tube clamp - these are no longer usable; toss them in the bin.

● Place the new hose clamps on the bypass tube and charge tube outlet.

● Slide your new BOV to the bypass tube and outlet to the charge and reattach the vacuum line.

● Fasten the hose clamp when all hoses are attached
