Collapsing turbo intake boot.

[Sheetmetalfab]

Has anyone ran into this?

Or actually verified it’s a problem?

@TRS this might be part of the high altitude “flat” power you were seeing?

Polaris Patriot Boost Cold Air Intake Boost Band

The Polaris Patriot Boost Cold Air Intake Boost Band is designed to be installed inside the cold air intake pipe that leads to the turbo. Once installed, this band holds open the cold air intake and prevents it from collapsing under suction. This product is easy to install and is a must-have for...

I’m wondering if that’s the wavering sounds you hear in some videos?

Mine runs great too. ??‍

It sure could be.

In deep snow with snow on the intakes we had a fella who ran into this

All I know is apparently I can charge 70 bucks for a hose clamp and beer can cutout.

Now taking orders!!

That was the first thing i noticed $70 is a little steep. $25 would be in range. Woundn't some silicone hose that was performed work? The above is a simple fix.

Give em a break. The after market turbo business is not looking very promising. Let them sell their $70 hose clamp.

We have run in to this in deep snow, and are sleeving the turbo intakes with 2 pieces of pipe cut at the appropriate angles. All good after that. This solution looks like it would work fine as well. Ideally needs a firmer OEM "exo skeleton" on that piece.

Sleeve inside or outside?

 

[turboless terry]

Seems like it has to be inside
I would rather have a whole new sleeve.

 

[madmax]

Ouch, $70?!?! Really, for $2 worth of parts.

 

[Jaynelson]

Inside. I imagine eventually someone or Polaris will have a whole new piece. We used quite a bit more material - but the product above probably works fine at a glance - if you think it's too $$, you can home-build one easily ?‍

Seems the pipe is most likely to collapse in deep snow, with some snow on the vents, at large throttle openings. If you're missing any of those items, you likely won't have any issue.

How did this ever get by Poo R&D - it's so simple - they've been testing this for years in pow - or was it a late change due to cost or availability? Someone knows. Idiotic. But these guys do/did make glued a-arms, carbon rear grab bars, footwells that break ankles, mt sleds without tethers, stuck vent oil caps, disposable ski dampers, and throttles that stick.

Price wise, just like Ferrari, if you can afford a Boost...

If the pipe doesn't collapse to deal with the reduced/lack of air intake flow caused by plugged intake screens, then something else will. Feels like an improvement in air intake surface area would be of better benefit, deal with the flow restriction not suck on the milkshake harder with a small capri-sun straw..... No one ever cheats physics and wins. No one. ?

 

[Jaynelson]

Have you actually squeezed the pipe? It’s quite flexible…much more than I would have guessed. Adding intake area may help as well, but I could definitely see it distorting regardless. Either way this is working…proof is in the pudding. We have had some *very* deep snow and some serious throttle squeezers to test…so far so good. I suppose you still won’t get away without swiping the vents in vent-deep snow …just like any sled.

Wouldn’t a couple hose clamps on the outside so it can’t start to deform do the trick?

 

[RHODESIE]

add a couple flow rites to the air intake under the console so it can grab some under hood air if needed should do the trick.

I tried this and it still collapses.

I think it needs more intake surface area and a stiff insert inside the boot. (Or a replacement silicone stiff boot)

Sounds like someone clapping their hands loudly under the hood and the sled noticeably slows.

It sure could be.

Confirmed it’s not what you were seeing.

Collapsing at 1500’ elevation in deep snow.
