Nice idea,.. not so beneficial if you need tunnel length for storage.
##2021 Season Low snow mod update-video##Another (better?) no weld solution for tunnel shortening.

I thought about doing that as well ... These things overheat so easily compared to doos ...
I was wondering how the MTNTK aux cooler would work when replacing the factory cooling system .... thanks for the update !

I dove in and shortened with their tunnel cut kit. Had a coolant leak where the end caps connected and had to drain and use a lot more RCV. It held through a 3+ft weekend in steamboat last weekend but my buddy and I were going to do this as the “fix” if it leaked ever again. Still holding but might do it anyway.
Didn’t have any issues with cooling while on trail with the Nexttech ice scratchers. never over 120-130, 80-90 in pow and it was a wide open weekend.

Running just the 5' cooler, no stock coolers at all, the sled runs 93-105 down the groomed trail at speed.
On slow, whooped out singletrack, not enough speed to throw up snow-- it runs 130-135.
In deep snow it runs 88 degrees.
I'm definitely happy with the result.
Perfect. My sled overheats on groomed trails going fast with scratchers down.
This may end up being an upgrade
Will probably go this route. Thanks for the update.

Nice job Murph. A couple of us had kept this one quiet....There'll be no more summer time discounts on these coolers.
As for snow build up in the front, agree. Eric had a great idea for that and I used to have it bookmarked before this crappy forum change.

Any updates ? Pics to compare after a days ride vs a stocker for ice build up on boards/side of tunnel.
hey Murphy any pics of how you plumbed it?
No pics, but he just disconnected the hoses from the stock cooler and connected them to the MTNTK one.
The inside of your tunnel looks like its captured all the snow/ice that the outside of your tunnel used to collect, maybe even more.
Regarding snow buildup—It’s different.
Better or worse?— not sure. It’s funny when I park with stock Pros, They have snow build up in the center, none on the sides. Mine is the opposite. There does seem to be less buildup in the front of the tunnel by the drivers on my setup— pretty important in our wet coastal snow.
The ultimate setup might be a bulkhead cooler with a 3’ MTNTK cooler and the stock coolers welded up around the MTNTK coolers. Zero snow in the first 3’ of the tunnel and zero cooler running to the tail—-The only downside I can think of is the inability to throw snow on top of the coolers on a spring day. Maybe the bulkhead cooler would make that unnecessary.

End of season update: I will be doing another little modification to help with the spring hardpack temperature regulation. I'll take photos when I do it.
I have a 2021 Khaos 165" on the way. I have a new MTNTK 5' cooler coming for it also. If you are interested, I'm a dealer for MTNTK.
A shortened tunnel, with the IceAge Khaos rails completely transforms the feel of a ProRMK. Way more playful/ fun. I just became a dealer for IceAge because I believe in the geometry change so much.

Are you going to do spindles as well?
More than likely I will try them.
