Nice! Im actually doing the exact same thing on my -13's 137" pro-rmk build.
Got my bottle yday.

137" ?
I have so many questions on skid choice and other details. So as not to hyjack this thread i ask Please please please start a build thread and share the details with us.

IYO... is the new Head/Thermo up to par with your ole external Doo stat setup?

Eric,
We will find out. I thought I would give it a try and see if it would help clean up the turbo compartment.
The doo stat worked great for me. The doo setup is cheaper.
Yes, a bracket needed to be built to hold the bottle. I splurged and bought the 850 hose from the bottle to the pump. I had to cut it? to make it work. I have a large assortment of hose bends to complete it, that part was easy. The added center cooler created fuel tank clearance issues that you won’t encounter with stock cooling. Heating the tank with a heat gun to made more clearance. Hope this helps.
did you ride your setup yet Tony?
No.
Just headed to get my complete exhaust system and turbo. I had them Cerakoted by a local shop.
New electrical connectors are in order also. Upgrading the Boondocker plugs and shortening the 5 miles of wire.?
5 miles, LOL! Yeah, such things are nice to snug up and organize.
See the bottle is $44 With Babbits, so if you are a DIY person with tools and a tiny bit of leftover parts, this will be a cheap coolant temp fix! Bottle cap is the same.
Nice little mod Tony.

Hard to see but I think there are 4 large hoses plumbing to this bottle with only one below the t stat? Looks like all return water (cooler water or bypass water) goes back thru the same hose to the pump. Trying to see the flow thru it and how the bypass for warm up is but I keep imagining an easy path back to the pump creating a short circuit not allowing full flow to the coolers when the stat is open. Is there another chamber inside the bottle above the t stat with a small bypass orifice that will only allow a small flow when the t stat is closed and bypassing? Tried to look at this on the parts blow up on line but Polaris only has part numbers and no diagram. Can you clarify to help me see the flow path?

Coolant goes in the bottle at the thermostat, with the thermostat closed it directs the coolant into the bottle and back to the pump.
When the thermostat opens it closes off the path to the bottle and sends coolant through the tunnel and back to the bottle. Does that help?
Yes that helps. From the pictures I saw the coolant hose coming from the engine with flow into the bottle and it looks to be above the stat. Also saw the output from the bottle for the cooler input coming from below the stat which made sense. Just could not see how the stat was closing off the bypass flow when the stat opened from the pictures. This looks like it will clean up the engine bay with the bypass taking place inside the bottle and sharing the return line to the pump. The Polaris diagrams I checked on line for 2019 800 engines do not seem to have this new bottle. The one diagram that Polaris has on line for an 850 Indy 129 shows more hoses going to this bottle and it looks like they may be running the front cooler and the tunnel cooler in parallel instead of in series.
Thanks for the clarification.
Sure does clean things up?
Tony if you don't mind sharing, how much in parts are you out?

The 850 hose was an added purchase. The bottle has an up size port.
Thanks Tony as always you are on the cutting edge . I was wondering how this turned out sure would rather spend $100 to cool my sled . I did the Doo stat on my 11 worked great .
Haven’t had it on the snow. Looks like it will work well.
Kids and Grandkids are here for the holidays. We went back to hunting��
Not a lot of snow here. It’s surely “dealer snow”.
