Small intercooler and lots of boost.

I guess another question here would be. Why are the darn charge temps so damn high on these 4 stroke 1100's. Are they higher than my M1000? Is it just because they are trying to get to 20+psi of boost?
The guy that figures out the right turbo, IC, controller combination to get these to pull from top to bottom without adding 3k worth of parts and 100lbs of gizmos and gadgets will be winner.
IMO, no one has it right yet. I know that will ruffle a few feathers, but honestly we aren't there yet.

Well hopefully we can have someone come on here and clarify what the real findings are on pressure drop on the stock IC. If we had some snow or even a open field right now I would fit the sled with another gauge and tell you exactly. I would guess 3-5 could be accurate but not 9 psi. A properly sized water to air should be around 1 psi drop across the core.
Modern 4 strokes run HOT. I know on the 4 stroke dirt bikes. The head pipe will be glowing red hot in the matter of 1 min of idle time. (In the dark). You won't see a 2 stroke do that.

Yea, I have noticed that also.
I think Turbo11T is on the right track with the heat being generated by the compression of the air in the turbo. On a two stroke we run 10-15psi so we aren't "compressing" nearly as much as a four stroke trying to run 25psi. So I think just trying to build that much pressure creates a lot more heat than a two stroke does.
One thing to remember again is it is the differential that creates the heat. If you want 25psi on the discharge, and are running a restrictive intake you will need the turbo to work a lot harder than if you have an open intake. (intake screen/sock vs air box/filter system)

Did anyone have a Super Chute clutched well enough that it would take 60-120 seconds of full power?
Me did

Do we really think this is all clutching? I am going to bet my Twisted M1000 at 11lbs is running pretty darn close to the HP of the Big Chute. I put over a 1000 miles on one belt last season. And I NEVER had a clutching issue, losing rpms, bogging, slipping, whatever in those 1000 miles.

Anyone try a straight charge tube with Meth injection? I understand some of the Yamaha guys have done this with success.
Works good on the big diesels.

So your saying "it doesn't work, so buy something else that does"
I think that is what a lot of guys are doing. Dumping the 1100's and looking at ANYTHING other than that, just because it isn't performing as they liked. It is going to take some big money, time and ability to make it right. I know for a fact I am not going to be Arctic Cat's test dummy, or any other aftermarket companies test dummy to make it right. But I know we have a lot of guys/gals on here that are pretty darn sharp, with some deeper pockets that can make this thing run. It's just getting people thinking differently rather than thinking this is the square hole, and this is the square peg for it. Your right we might need to look at fitting a round peg in a square hole.

I think some people just get hung up on the fact that they've spent over 20,000$ on a sled so it has to be good!!! And they will defend a mediocre sled to the end because they have spent so much on it. It's not about leaving "good enough" alone. It's about addressing real problems with these sleds. And heat is one of the many. No need for people to get all defensive because they spent so much money. If it doesn't work good, it doesn't work good! There is always room for improvement. It's not taking a round wheel making it square and starting over. It's about making a bias tire a radial, it's about improving on a design to make it as close to perfect as you can. So you can be truly proud of your $20,000+ spent.

BINGO!!!!
You just nailed it!!!
I try really hard not to bad mouth anyone, especially the aftermarket guys, they are working hard to stay alive and do a great job. But again just because you spent an extra 5k or more on mods, doesn't mean it's perfect. We can always move forward.

Thunder that is NOT what I am saying. What I am saying is that companies such as Evolution Powersports have hundreds if not thousands of hours into building mapping and testing and building hard parts. What I am saying is if you want to ride rather than wrench and push buttons everyday on the mountain buy some Evolution.
Also remember that the 1100 is not for everyone. No different than the nytro.
I for one enjoy the reliability that I get from the 1100. I enjoy having a machine that works as well at 1000' then I load it in a trailer and haul it 1000 miles and unload at 8000 ft and it runs just like it does at the low elevation. The ecu is tuned to perfection just as advertised.

Again. . . Not defending anything. Some of the 2stroke turbos run very well. Some love 4strokes. Some don't some don't know what they want.
As far as mediocre. Not so much.
Yes I do. Rode it once last year.
Don't get the idea that I'm un happy with the big chute. It runs really well. I'm just always looking at ways that could improve a sled. It's summer time man. Gotta kill the time somehow! I had a 09 m8 with a ovs race gas tial kit on it. When I bought the kit from ovs I talked with Travis about the 1100's. He told me what they had found to be the ups and downs of the sled. The biggest down was the undersized intercooler.
All I'm getting at is maybe something as simple as a more efficient IC or even non IC could help some sleds out. Insted of going to the cost extreme of a air to water kit. Would like to see some of those thousands of test hours to disprove my thought.
