M1100 turbo clutching question

Since a stock 1100 turbo has the same HP up to 10,000 feet, does that mean there would be no clutch adjustments needed for riding at sea level vs 10,000 feet?

YOU GOTTA BE KIDDING MEE!!!!!!!!!!!!!!!

clutching

That is a interesting question. I would assume that if it is the same HP all the way to 10,000 feet the clutching sould be good. And I am pretty sure I will have one. Just want to ride one first. Looks good. Speedwerxs has a program that has 210 hp for 400.00 pretty cheap HP. Just my opinion.

I can't imagine that you can run the same clutching at sea level and 10k feet...even when running boost and negating the horsepower loss.

I would think clutching would change somewhat due to off boost power, and increased spool time at high elevation. The same clutching may work OK at both levels, but to optimize performance, I would assume some changes would be necessary.

Turbo's are altitude compensating to a point. You will not push the exact same numbers with that large of a elevation change. Spool up will be slower and your engine will run much differently. Air density and temperature is a huge factor associated with elevation change. Your torque curve will be differnent as will your RPM which will effect your clutching.

are you going to buy one??

I thought about it briefly, but probably not.
I would love to not have the power loss at altitude.
I ride some in the UP of Michigan and mostly Colorado
(that is why I asked the clutch question) and would love to have the
power at 13,000 feet that I have in Michigan.

But I am more of a power rider than hillclimber and while I will buy a new sled for next year I dont' think I will buy 2 at around $13,000 each to be covered.

100% incorrect? I actually went to school for this ****, Work for Caterpillar and know exactly what im talking about. Oh and i also own a EFI turbo sled and know first hand that even the engine will only compensate to a point also. Why the **** do you think you have a fuel box with different maps to adjust for elevation? You need to go read a ****ing book a sled at sea level and 10,000 ft will not perform the same whatsoever. Also do you know that your turbo will have to spin almost twice as fast at 10,000 ft then at sea level to try to compensate???? I ride at 6-9 thousand feet and when i go back to ride around boise area 3-5 thousand i rev higher and have to adjust my fuel box accordingly for my fuel.... These are simple facts, you should know them before you try to bash on someone.

Set aside from that, you will not see much difference in clutching just slight adjustments. Weight in your primary will be the biggest factor im sure and minimal at that. But to expect that sled to run the same at both extreams of elevation would be alot to ask. But what would i know, Ive only been ridding for 15 years and owned multiple mod sleds and two turbo sleds.......:face-icon-small-win

u are correct but if they are running something like the boondocker digital boost controller set up it reads berametric pres and keeps the same boost at elevation . i think they are running this style of setup.a normal set up u well hav to pull and add fuel at diff elevations if u were running diff boost.this new set up is way more user friendly.

They have to be running an ebc or something similar. No way are they going to kick out a factory turbo and allow you to adjust your own fuel settings and still have a warranty department.

Not to get off topic here but after reading this i noticed something.

It says you ride at 6-9K feet. Then it says in the Boise area are you riding at 3-5K feet. Where in the Boise area are you riding at 3-5K feet? Horseshoe Bend hill or something? Just curious.

I ran the same clutching from Minnesota to Cooke on my Apex, There was slight changes to be made as far as cranking up the boost but It worked great both places.......... You never will have the bet of Both worlds but I think this is the best you will find for a stock sled
