Does anyone here tear out their foam under the hood/panels?

I'm sure we will all agree with you.... when we are 65 and ride trails all day ?

i'm not 65 and i don't ride trails at all , the foam is closed cell ,that means it can't absorb water , it can get ice on it . i have built many light weight sleds and foam is on of the least effective ways to remove weight , if you think your saving something ,it's in your head

The foam inside the engine compartment holds an unbelievable amount of water. Call it whatever you want to call it but anyone can go out to their sled right now and squeeze the foam and water will come out. I highly doubt there is enough heat to dry the foam out why you are riding. Removing the foam is the cheapest way to cut weight on your sled.

Does your wife’s sled have the heavy foam removed?

 

[turboless terry]

She isn't as sensitive to weight as chadly

Foam party….if you attended one of those, you’re immune to covid

There was 1 pound of dry foam in the axys chassis.

Remove the foam!
Once the water freezes in the foam it makes a Huge mess

Meh seems like a pita for a limited return. I have not removed the side panel mid day and been “taken aback” by the weight yet. To another posters point - if it’s closed cell foam it’s not absorbing much.

Frankly I dumped the stock exhaust for a diamond s and didn’t notice much. Looks cool, sounds good, nice to have a warm lunch. Worth it sure - but if you are barely noticing that, you aren’t noticing foam lol.

This stocck panel foam absorbs a lot of water. If you don't believe me, take your panel off (in a heated garage or bring into your house) and see how much water you can squeeze out once it's not frozen anymore. This amounts to pounds of actual sled weight.

And agree with previous posters that most people's thawing/drying regimen doesn't accomplish a full drying of the panels. I can leave my sled for 3-4 days with panels off in front of a small heater and fan and still have water dripping out in mass when I squeeze it. Closed cell foam still absorbs lots of moisture in this application.

The foam on these is not closed cell, neither the light grey or the darker variant, both are quite porous and absorb a lot of water. Water beads off closed cell, like a ridge-rest sleeping pad–not this foam, soaks right in. I also agree it does not thaw quickly. Water streams out of the foam when squeezed after 5 days in my garage, sled's dry in a day.

This weekend I was getting a fair bit of ice build up around the front "triangular" portion of the Matryx side panels, as well as around the panel latches. Only a minor annoyance, but enough that I think I'll be pulling the foam. Weight savings aside, all that moisture can't be helping things.

Removing the foam adds quite a bit space under the hood also and I totally believe it's actually enough to help with air flow and cooling.

If you've never gotten the foam wet, you haven't ridden it.

It may be ounces before it's wet, but it's pounds after, and it won't be fully dry until next fall.

If stock clutching calibration is good enough for 97% of all of you, why isn’t leaving foam in good enough for 97% of you?

I costs approximately zero dollars to tear the foam out and takes approximately zero mechanical ability.

Haven't got the foam wet on my boost. Your right, i Haven't ridden it.

Apparently when you do a bunch of acid you can't afford zero dollars and have negative ability ?

He's too busy getting his wife's wet ?

Same here but I’m sure its nice and dry somewhere in the factory

I leave 97% of the foam on and over time 3% finds it's way into 97% of my clutch.
