Pipe is Melting Hood

[nuggetau]

After riding in some good powder for about 10-15 minutes I could smell something burning. I stopped and began looking for the cause, it was getting so hot under the hood(from the pipe) that it is melting the hood and has melted off some of the tabs that hold the screens on the hood. The motor temp never got above 129 degrees, the sled is stock and has not had any damage. (13' pro 800)

It is impossible to ride it without the hood becoming loaded with snow blocking the top vents. I am left wondering if Polaris ever actually rides their own product on anything other than a trail in Minnesota?

I have had this happen to edge tub machines always when going slow in power with a lot of throttle cowling covered with snow. Under hood temp will be very high in these conditions. Helps if you can there to keep vents open. I also applied heavy foil tape to plastic in areas near the pipe. No sure but this might be covered by your warranty.

In good snow it takes less than 30 seconds for the 2 nose vents and the top of the hood (vents) to be completely obstructed, so you get absolutely zero air flow over the top of the pipe. You can have all the side panel vents you want, but that won't have hardly any effect on the trapped heat above the pipe (unshielded side coming from motor).

There seems to be only 3 options, wrap the pipe, heat tape all over the hood, or a vent in the side nose pan. I elected for the latter, but it may ice up and not work that well either. Which would bring me back to the other 2 solutions.

My 2011 had some hood melting going on... Added a bunch of the inexpensive foil heat tape and have not had an issue since.

I am going to try this vent as it is positioned directly under where the hood is melting. Who knows how effective it will be when it gets iced up?

I have that front vent on mine and it works great because the heat from the pipes keeps it from freezing..

 

[nuggetau]

Good to hear, I hope I get the same result.

I looked at an exhaust side panel yesterday that caught on fire , it was warrantied , they no longer have the good heat sheild material that they use to have .

--Of course they don't. The sled is built pretty cheap. A beancounters dream. Big names, great flickability. It also has the most profit margin of any other manufacture. Nothing wrong with making a profit, but I think the shark tank guys are running Polaris now.

--Many hours and miles of fun on these machines, regardless, there is a growing list of items that should be addressed

There are 2 ways things get hot under the hood convection and radiant heat. Vents will help with the convection (direct) heat, tape will help with radiant heat.

It may not be the "best" but it can not hurt. I had some of the DEI Boom Mat left over from my car. It does offer some protection from heat on the plastic belly pan where the pipe comes close.
Idid apply some under the hood also.

Who makes this vent

 

[jtpolaris]

Moflow does and. Xxxmodrods does too.

Doesn't matter what sled nug buys always has some issue. He bashes every brand he has had since I've been on here get over it. It's a high performance toy made for fun not every sled is made for every condition these sleds need to breath. Loading a sled heavy with no air flow that's what happens if pol would have vented it more on certain apps the motor would not get to operating temp and performance would suffer. I've burned holes in hoods it happens in certain conditions but it was fun part of riding.

I think we'll see more of these problems as time goes on my, 13 is melting the tabs for the front vent on the nose of the hood.

Polaris move to Mexico, is showing some cheap parts and quality of workmanship.

Try the Frogskin hood vent kit. If you apply the vents so that they lay flat over the vent openings it creates a surface that the snow slides off of very easily. Seldom if ever do I have to brush snow off the hood- it just falls away.

Hey nugg, why don't you pay somebody $300 to make your sled not melt?

 

[minecat]

the blow hole from MTN tek would solve your problem did mine
