Nice!!
Run that sukka in series with the main coolers IMO...
No cooling problems there... and no "plaque" build-up at the front of the tunnel either.

I have the RMK front cooler, do you guys think it should be run in a series instead of the way it is now? Anyone done this? I have a couple of the Ski-Doo external thermostats around was planning on throwing one on. Just grabbing opinions/theories before starting to throw this sled back together.
RMK front cooler does not have the flow capacity to run in series unless you modify it with larger inlet/outlets.... lots of work.
"Lots of work"?
That depends entirely on your individual skill set. For a skilled fabricator with aluminum talent that is about a 20 minute modification. Once the engine is out and anti-freeze is drained.
It wouldn't be much of a job for me, just wasn't on my list. What are the thoughts on the standard RMK, does it need much more cooling, or will running it in a series provide that much more (better)? Has anyone else done this, big pain in the arse would be to do it and have to go back.
"Lots of work" means taking your sled apart...Pulling the engine, cutting off the old barbs, fabricating the bend-nipples needed, fitting and cutting the cooler in/out holes and welding them on with precision....then putting the sled back together...
For many, would be considered a lot of work.

and I'm sure from what I've read on here there are guys that could just think about it and it'd be done!!! It's just that easy...

Update...
Tried to put my peak 2.5 track in and no fitty. Hits the bulkhead cooler at about 1 o'clock when looking at the chaincase side. Err. 7 tooth drivers and mod chain case here I come.
My custom tunnel cooler also required more room hence the smaller drivers are going on.
Assault track does fit though. So if you had one of them or a trimmed 5.1 that would work.

Update
I've put about 400 mi on this setup so far. Went with oem polaris hose to the lower port and used a 1" tee too hook the top port to the bottom coolant hose.
Running this chop tunnel sled now with a external silber kit w/ 5 psi spring @ 1100ft.
Everything fits fine now with 7 tooth drivers and chaincase mod spinning a peak 2.5...had to throw the stock comp track on for the wknd since the peak decided it didn't like it's lugs.
Runs hotter than a stock pro on trail but the same when youre in snow.
Put a rmk style cooler in the wife's 14 pro with all the oem parts...about 6 hrs start to finish now and can do it for under 200 if you find the cooler for about a hundred bucks.

Are you running full flow through the front RUSH cooler.. or do you have it "T'd" into the rear circuit...or are you running it as a bypass cooler?
