OVS M8 RG bogs in deep powder anyone have a good way to keep the air flowing in

[TahoeMuk]

My 09 m8 OVS RG 163 straight up kills it with 12-14lbs all day everyday - thanks guys! the only problem is on big days I cant keep it breathing and as soon as I cover all my vents (I have both sides with the ovs kit, top of the hood has the huge triangle vent and vent behind the right ski in front of the intake) just about everything I can do to keep it cool and vented, but during the days when the turbo is breaking trail, I can only run until sooner or later I submarine and clogg the vents- then its a quick turn to get back on my track before I'm limping on what seems like a single cylinder sled- I stop and clear the vents and I'm off and running no problem - forget about doing slalom downhill turns- grrrrr!

My question is has anyone figured out a way to keep it breathing- I'm about ready to cut a hole for a dorkle (dork+snorkel) like the jeeps have- I think a good 5 footer with a break away mount sticking up should do it - picture that! anyway - thanks in advance

tunnel dump would help prob

On the real deep days I had the same issue. I have a vent right above the intake, one right in front of it and ones in the nose cone area. Had to buy some material from SLP to cover the vents because they were allowing too much snow through and the intake filter would suck up all the snow and choke off the air. Bought Frog skinz covers for all the other hood vents.

Same problem. the side dump is one issue i have in the deep but the other is the vents getting plugged with pow. The Dorkle idea i have been looking at as well for a solution. Little Orange Cat on here has a dorkle through the hood on his T1200 maybe he will chime in on how it works

put the frog skins on, its the all the steam under the hood.
I havent had a lick of problems with the side dump, other then sitting at ideal if I dont clear the area in front it will load up when I take off. When Im on it, it doesnt care.

even in 5 feet of fresh?? when side hilling on the exhaust side unless it is pinned WFO the exhaust is smothered and the engine will almost die. Are you boondocking and shooting through the trees, doing downhill turns in the deep? exhaust gets suffocated for me. Maybe the 1200 has more pressure and it blows the snow out of the way

Tunnel dump.

Very easy to do and only cost about 150.00

Ps also so much quieter I hated the side dump.

It has nothing to do with the exhaust. I have a tunnel dump from MMS and I do like it. However, I ride with an identical OVS M8 with the side dump and our sleds respond the same. We have some insane powder in Eastern Idaho/Western Wyoming right now and when I'm breaking trail and pushing a lot of snow (over the windshield) my sled will run out of air and I have to sweep off the snow. We both have the same issue along with the 2 BD turboed sleds we ride with. We do have a guy with an '09 M1000 with OVS turbo and he has a snorkel coming out of the hood and he never runs out of air (he has the side dump too).

This is only a problem in insanely deep powder. I'd rather keep the intake under the hood and away from hitting objects and risk sucking in a foreign object.

On another note. I have to say that I'm not sold on the intercoolers for boondocking sleds. I think they create more heat b/c it's hard to keep air flowing into them. We have 2 sleds that run the intercoolers and they get HOT quickly!

do you guys have a prefilter over the turbo intake? meaning air can not get into the turbo unless it goes through prefilter material?
Snow, snow flakes, powder getting in the turbo will cause it to bog.

Yes, that is the issue on mine in the really fine snow. It sucks up snow on the pre-filter sock and just keeps stacking on till it chokes the intake air. It is a lot better with the frogskinz. Before the frogskins I could open the hood and there was snow from the bottom of the tub on the turbo side all the way to the hood. Sometimes you could not even see the turbo intake.

bogs

I rode today with. A sled that has the cold air intake. No improvement at all in fact I think worse. I had to lean my mid out just a bit but just lift and cleans right out no problems at all. Well must have got a little lean had to use my switch about half dozen times. Had one of the best rides I am absolute wiped out.can not wait for tomorrow.
