Can-Am Maverick R Catch Can Kit

The EVP Catch Can Kit is designed to eliminate oil/crankcase vapors from being ingested by the turbocharger, which contaminates the intake charge. Rather than go the easy route of mounting to the firewall where vapors easily infiltrate the cab, our CNC-machined billet aluminum separator mounts to the frame rail toward the rear of the machine.

Like all things for the Maverick R, we took extra time to ensure the catch can system for this vehicle was the best it could be.

When we looked at mounting locations, we wanted to avoid the firewall because we did not want the vapors coming out of the catch can to contaminate the driver/passenger. This would be incredibly obnoxious for customers with a windshield due to the low pressure in the cab, which would easily draw in the vapors and make the situation even worse. We chose to locate the catch can on the frame rail toward the vehicle's rear. The other consideration we had to take into account was crankcase pressure. The key to maximizing power output for a given tune is to get the most efficiency possible. Any crankcase pressure directly reduces maximum power. The proximity of our chosen catch can location meant that we had to lengthen the hose from the valve cover to the catch can itself.

Anyone with a basic physics understanding knows that as hose length increases, so does the resistance to flow. Rather than go the easy route of supplying the same ID hose, we had a custom-made hose that increased the diameter of the hose for most of the run from the valve cover to the catch can. The increased diameter reduces backpressure in the crankcase and allows for maximum engine efficiency. Lastly, we carefully considered the draining process of the catch can, meaning we wanted it to be easy and clean to drain. Our catch can include a stainless steel petcock, stainless elbow, and routing for the drain hose, which is hidden by the bodywork of the vehicle. To empty the catch can, simply put a suitable container on the ground below the drain hose and open the petcock until all the fluid is drained. Simple, easy and clean.

What is an oil catch can and why do you need one? The factory recirculates crankcase air back into the intake. This air contains oil, moisture and other combustion byproducts which contaminates the air that is being fed to the turbocharger. The oil and water infused air coats the turbocharger compressor blades, charge tubes, intercooler and intake valves. It can also change the air/fuel ratio and lower the effective octane of the mixture being introduced into the cylinder. Oil has a very low knock threshold, therefore the more oil contained in the incoming air, the lower the effective knock protection of whatever fuel is being used.

The EVP Catch Can Kit was designed with features to combat and eliminate the issues described above for both stock and tuned Maverick R's. Our CNC-machined billet aluminum separator mounts to the frame rail, avoiding the firewall. Rather than go the easy route of supplying the same ID hose, we had a custom-made hose that increased the diameter of the hose for most of the run from the valve cover to the catch can.

The internal baffle design features a perforated stainless steel cylinder plus additional steel screening to help the oil-infused vapors condensate correctly. This allows the oil to separate from the mixture and also prevents it from further siphoning out, letting the vapor escape via the filter for improved overall performance.

All EVP Catch Can kits also include a high-quality filter element, pre-filter, and now come equipped with a new petcock-style draining valve at the bottom for clean periodic emptying of the contaminants. Emptying the excess contents is now quicker, hassle-free, and will leave zero mess on you or your surroundings—a great new feature of the updated EVP Catch Can design.

A silicone cap is supplied to block off the port on the intake boot where the OEM breather hose is connected. All hardware is stainless steel and the body of the separator is powder coated black. The billet cap can be clocked in 45-degree increments to allow virtually any installation orientation. Not only that, because the cap is removable, the catch can can be disassembled if desired to fully clean out the contents.
