Alpha needs AIR in the pow!

[skiutahcabin]

Last year was so deep I found the alpha suffocating several times as everything blocked up- usually right when I needed max hp, I'm thinking of options here- any thoughts on adding boondockers external air filter (turbo style) to the top by the console?

I haven't looked into options but the alpha sucks, in really deep powder, due to no air. If you don't think so you haven't been in deep enough powder. Why they would put a half inset intake where snow can lay in that little crease between the hood and windshield is beyond me. Plugs it off right now. Look at the skidoo 850. They are susceptible to branches but they don't bog in powder.

Jeez, when I'm in over the hood powder I just reach down occasionally and make sure something on intake is open, it's not complicated lol

That’s lame af. Throttle.....bog.....wipe intake off.....throttle.....bog.....wipe intake off....

 

[turboless terry]

What do you think I did to try an keep it going? Hard to do in some terrain or your stuck. It also gets really old. Sad for a mountain sled to be this bad imo.

? why off throttle? cant you ride with one hand? dont you ever wipe off goggles? and no bog thats the point, I can see when the dash is getting full, I just brush it off before its a problem, its not complicated

 

[Dam Dave]

My M sled bogged a lot, none of my Pro climbs or Ascenders have really had a bog, easy to keep intake clear for sure, stock sled or Mod? what mods

guess I have been lucky

just FYI I live in the mountains and ride every weekend in deep Colorado snow and also travel to Idaho, Utah, and Montana to ride so I do ride in deep snow, sorry you are having trouble but not sure a turbo filter in the same location as stock filter but a lot smaller surface area is going to help? just asking

Sure I can ride with one hand, in the meadow. Taking 10 seconds to clean the intakes is complete different than the 1/2 second it takes to wack the side of my helmet to shake my goggles off. Try cleaning the intakes in a super steep sidehill that is high consequence, trees, cliffs, boulders...... If you think it’s “not that hard” you probably don’t ride that extreme of terrain. Not trying to insult you, just being honest.

Other than that, it’s dumb af. Why not just have a sled that runs no matter the conditions??

 

[turboless terry]

My guess is a difference in how deep or a difference in how we ride.
My m8 never bogged but had a bd with tunnel dump

Ten seconds? okay now you are just making stuff up lol

I noticed this as well last year. But it took a 3-4ft dump of light pow to have this issue. And yes it's still annoying wiping with one hand and riding. I guess one could install a SLP powder valve on the top of the airbox before it goes into the throttle bodies. Will be sucking in hot air, but still better than bogging like crazy. Since it only happened to me on one stupid deep ride last year I'm just gonna deal with it.

 

[skiutahcabin]

So-- yes, we have established the issue- and I ride in the areas where I don't have time to stop and wipe it clear when it is most critical- you simply don't have the second or two in high consequence terrain to have a hand off the bars and be messing around RIGHT when you need a horsepower kick to get out of a mess.
,So- we know there's an issue here- lets talk about a FIX! My concerns with a traditional rigging a 'stand-up' external filter to the OEM hood/intake are:
1. it's mounted to plastic intake
2. the sled is getting rolled all the time, so there is risk to snapping it off if it's too rigid.

I have thought to fab a silicone line connect it lower inside and give it a couple inch riser up by the top where the bars are so there is both flex and some protection, but one of you may have a better idea! -???

Looks like SLP is saying to set them up on the outer sides, to be clear, you are thinking internally- maybe both?

I guess I’ll share my secret. This is my home made headlight delete, but with a small aluminum sleeve you can do the same with the stock air box. Inside the pre filters are silicone rad hoses. With square windows cut out. It’s just a frame to hold the pre filter out, super flexible for rolling the sled.

wow, THANKS! -fantastic! Very nice! it looks like you could do this with just porting the ends and inserting the aluminum sleeve and then putting the silicone onto that, right?

Just curious if you have a can on your sled? I've seen a TON of exhaust bog issues on the 18+ cats when deep. Rode them on some insanely deep days and never had intake bogging issues but definately exhaust bogging. Also if the intake junction and airbox isn't all sealed up it will suck snow and bog you down like crazy.

 

[badaltitude]

I’ve got hours of video of over the hood snow and zero intake bogs. I do run the mountainfit defender. I have seen lots of bogs on deep days from cans and intakes that aren’t sealed up.

The last two posters are correct! 95% of any bog is usually related to the sled ingesting snow, or your exhaust is not specific to the Ctec engine. Firstly stay away from those exhaust systems, and get a exhaust system that is designed specifically for the Ctec or keep your stock muffler on! Second your bogging not because your filter is plugged. The intake screens pull air from both up top and from underneath. On super deep days I have pow piled on top of my intake up to my bars and never have a bog.

Everyone needs to check there front nose cone section of there hoods. This is my 2020 Hardcore, before I sealed it. If you have gaps like this and can see light through your intake when putting a flashlight behind it, on deep pow days you are ingesting snow and the snow is causing the bog. Also if you have a 18 check your upper intake for gaps as well
