Snow flap extension

I have been been looking for a suitable material to extend the snow flap on my two 2015 Indy 600 SP's. I wanted to share what I ended up with. I took a typical office trash can and sliced it up using a sharp utility knife. I was able to make two flaps extensions out of one can. Hopefully the 2.5" extension will help keep them cool in low snow conditions.

I cannot believe how many posts there are about extending the flap or adding scratchers. Polaris should be ashamed. So far I'm not convinced I need to do either BUT one weekend on hard pack trails may change my mind. So far I have been able to keep it barely in check by seeking out loose snow when it climbs. I like this waste basket idea. The curve looks perfect.

To be honest, the first year I had my Indy with the stock track I had ZERO cooling issues. Ran 120-125 all day except when the snow got a little too sloppy. But, this year I added a tracks USA 128" kit, and I had lots of snow flying out underneath my stock snow flap.

I never had cooling issues with the stock Indy.

Put another 40mi on today and can definitely say the flap helped. With the stock flap, outside temp of 8 degrees I made it 5mi before temps were 155. But the trails were hard. Today outside temp was 25, snow was looser and never had to drop the scratchers. Highest I seen was 145, averaging 138 or less. Speed seems to have a big factor in temps, under 25mph it starts to raise, pick up the pace and it cools off 5+ degrees. Flap is a must do for anyone with deep lug track and or stretched.
My setup is 136" cobra no studs (yet)
Tunnel protectors with holes drilled
I will get a better idea on how well it helped tomorrow as today's findings weren't the same temp and conditions. Forecast is 7 for a high so the trails should be just like they were when I tested the stock flap

I will disagree on the if you're extended/deep lug you need a longer flap. I run a 14 Indy 136" stock flap. I also run duraflex scratchers all the time. 95% under 130°. If I was running 138° I'd have my scratchers down. I run the stock flap so when you're playing off trail the snow shoots out and doesn't get trapped in the tunnel. So from my point of view and my personal experience. You're better off spending $50 on scratchers and leaving the stock flap. As compared to spending $35 on a flap then also spending $50 on scratchers just in case the trails are hard....

To me 138 isn't that hot. my sisters Indy 800sp with 121" completely stock with 20mi on it was also running 128-138 depending on speed today. My goal is not to rely on scratchers all the time so if a $35 flap can keep temps to what I feel is ok than that's a win to me. If I was seeing over 140s consistently then yes scratchers would be down but again that's me.

I did the SKS flap as well. i pounded out the mounting flange so that the flap almost hits the back bumper. i was able to poke a hole in the middle of the flap and use the stock mounting bolt in the bumper. Not sure how long that will last but it seems to hold up pretty well so far. we'll see after i back into a few snow banks on my next trip lol.
