Boost Bog

[Chadly]

The airbox in the 23 has a little relief valve that can steal hot air from the engine compartment if the screens come clogged with snow. I rode my 22 in 3' of fresh today and the exhaust bog was pretty bad anytime I went to U turn around to the right back up the hill. Almost got me stuck a couple times. Today was the first time I ever had a problem but it was silly deep. The bog caused from the screen being covered is a workable bog. It's just like really bad lag. Riding with Doos today it really made the crappy bottom end of the Polaris Boost stick out. I wish Polaris could somehow clean up the bottom end. You guys who don't think there is a problem are kidding yourselves. And for guys like Rusty who think you can "clutch" around it, it just kills the top end. I wish I was a crappy rider like you guys so I could live in your dream world of the Boost being such a magnificent sled.

I had a bit of a bog/hesitation the other day. Took the sled to the shop yesterday for an exhaust valve relearn…..mechanic tried a bunch of times to do the relearn but it wouldn’t work. Waiting to hear if Polaris is replacing the cable

Wouldn’t work because of low voltage or broken cable?
You can do a relearn with digital wrench and the engine running if it’s a voltage problem.
Or use EzLynk. A great tool to have for this simple reason.

That’s cuz your primary spring was broken silly goose.

Well that made it worse for sure. But no it's a laggy boat anchor with a good primary spring.

Sorry, I should have worded that better…..I believe he meant that they tried to relearn the exhaust valves but the ev code/engine light wouldn’t go away.
Ev cable was replaced and the mechanic said all codes/engine light have disappeared. Now they are trying to figure out why the 7s screen keeps turning off after 3-4hrs.

The rubber hose/boot between the air box and the turbo collapses. They used a rubber that is too thin. Mine used to bog until I inserted a ring inside the rubber boot to prevent it from collapsing. Hasn't bogged again. You can also buy a stiffer aftermarket boot:

RMK 850 Patriot Boost Silicone Intake & Charge Tube Kit With BOV Optio

Patriot Boost Silicone Intake & Charge Tube Kit RPM as promised has developed the strongest and most durable silicone upgrade kit for the Patriot Boost line up. The soft rubber OEM tube is problematic even for bone stock sleds. It is simply to thin and is collapsing on itself. RPM's 5 ply HD...

Need more context here. Is that it super deep? Are you in a right hand sidehill? Codes? How do plugs look? I bog when the snow is piled up to the handlebars even with f&i vent.

All different types of snow - has been deep last few rides out but ridden with 23’s that aren’t bogging -
not specific to right hand side hills
Have changed plugs, they didn’t look too bad
No codes

I swapped my 23 air box for a 22 ?

I was going to get the 23’ air box, but had one of these slp vents already so I thought I’d try first. Similar principle, higher intake vacuum opens it. Dont think it flows as much air though as the Polaris valve.

 

[FriscoProx]

This was from the Dealer Show. Anybody if this is new and/or if standard on 24 Boost?

 

[PSI 800]

Its not new, been on the Booster since they released it

 

[madmax]

That’s not for bog, it’s allow air intake when not making boost on the low end.

Polaris sucks and sent me the old style when I crushed the one on my 9Ramd I didn't want to wait for the updated one. It runs fine. Never had a bog problem on the 9R but I also don't ride my 9R when it's handlebar deep.

When the vents plug on the Boost the new valve in the intake whistles loudly. It’s not big enough.
The Boost needs a redesigned intake.

Very frustrating- love boost when it runs but has me thinking 9R or ski-doo
What’s the point of making “deep snow” sleds if you can’t ride em in the deep snow ?
