I am installing the power steering unit and had to remove the floor board. After talking with ranger 29.5 I decided to take a look at the exhaust on my belt cover. It drops down right behing your legs so it would be very easy to take on water. It is coupled with a rubber jointing piece you can find at hardware stores. So today I will be going to Lowes and buy some fittings to take it down to a size of hose I can run up under the hoods as all the others are. I don't know why Polaris didn't go the extra step to do this mod. They run Air Intake, and Belt Intake but that was it. I will get some pictures up later.
How to snorkle the belt's exhaust tube

I purchased my accessories from Lowes. I purchased a 2" pvc coupling, a 2" to 1" reducer and a half a stick of 1" pvc. The 1" PVC is was cut about 4" . Leave enough of the 1" sticking out to attach the hose. The hose is a heavy duty spiral hose. And you will need to hose clamps. I checked the flow of the belt's air coming out the restriction was not enough for me to try to go with 2 hoses or 1 bigger hose. Total cost was 35.00

I went under the radiator hose by the aluminum shield, and ran my hose down by the intake snorkel:

You have to rotate this picture to see it right. But I ran the hose under the differential and back over. This clears anything from rubbing. I then wire tied everything in place.

Keep one thing in mind when down sizing the outlet size you will raise your clutch and belt temperatures.
Just a caution. When working with the fluid dynamics of pneumatics (air flow), do not reduce the size of either the input or output tubes on the belt cooler. Because you are increasing the friction on the column of air by adding additional length to the hose you should increase the hose size by at least 3/8 of an inch over the ID on the OEM fittings.
Take a look at the venting system on the new Teryx, and you will see how they upped the vent sizes to reduce belt heating problems. The same thing applies here, only ours are faster and a lot tougher on the belts! I know the RZR is faster, I kissed a sneaky tree racing against my kid's Teryx. Not to worry, I really tromped him right out of the hole and clear through a quarter mile before the stealth tree snuck out and attacked my front fender! Then he had the nerve to complain about parts of RZR fender and tree bark sailing by as he tried to catch me.
Back to the issue. If you have a laser thermometer and know some Teryx victim run the RZR and the Teryx hard for about an hour and shoot the case temps on the back side of the belt. The RZR runs nearly 120 degrees hotter. Open up those vents, and the RZR will still run about 70 degrees hotter simply because the Teryx has a bigger fan on the back of the primary and can more more air.
I figure this air flow issue will become critical come summer when the air temps are in the 90's and 100's instead of the 30's.

I was wondering why there were vents on the belt housing, I learn something about my Ranger about everyday here. Anyway would there be a problem running the engine air intake and the belt air intake off of the same snorkel tube????? Or would it be better to run them separate????
I am working with an engineer on coming up with a good tube to snorkle the belt exhaust. I think what I have done would work fine if you use it for just getting in deep water. But not running it all the time. I would like an exhaust tube that is big enogh I don't have to worry about switching it back and forth.

I have briefly looked at the option of running the exhaust hose back toward the rear and up inside of the front of the bed wall. There is a gap in the bed wall and the black plastic could possibly be cut allowing the tube to exhaust between the bed and seat back. If it could be done this way, the tube would be much shorter than routing it to the front of the Ranger. This concept needs further examining to see if it can be done.
