Just a thought. How is this going to affect Cat for the Alaska Iron Dog next year, with them lacking a 600. I don't know all the rules, but will the 1100's be allowed? Maybe some 600 carryovers???

They still have there racer with the 600 and the yet to be unvailed 600 that is coming. The 1100 I doubt would be very competetive with the competitions rides. Could be wrong though.

They would have to rewrite the rules slightly for the 1100 to compete in the race. This is a quote from the 2011 rules.
 Quote:

2.1. Pro Class snowmobile engines exhaust systems, and intake systems are to be OEM
(except as noted below) and limited to the following: ISR approved 600 Stock Cross
Country snowmobiles in 2 and 4 stroke.
2.2. Two-Stroke Engines: 600cc maximum displacement.
2.2.1. Approved ISR 4-Stroke Model(s): Yamaha Nitro.

The only 4 s sleds allowed this year were specifically mentioned.

There were some teams using the CC 600 sled this past race.

Thanks for the info. I just got into it this year and tracked them from start to finish. I was at work on their last day and it was quite a seesaw finish, but I was still able to follow it. I'll be all over it for next year. From what I saw it, evey team ran 600's. That is why I was wondering about the Cat's.

Also for anyone interested, there is a movie coming out by the name of "Seven Days to Survive". Don't know too much just yet, but it is about this years Iron Dog.

I'm pretty certain the 1100 will be allowed to run. It is only 8 cc's bigger than a Nytro and makes less power. Cat will probably be pushing for guys to race the 1100 since they don't offer a consumer 2-stroke. The 600 Sno-Pro is carb'd and the engine has to be detuned to run low octane gas. I'm not sure if any Sno-Pro's have even finished the race? Nobody runs a Polaris IQ 600R in the Iron Dog for the same reason.

If the 1100 rides and handles well, it should be a good sled for the race.

Thanks AK. My cousin and her husband lived in North Pole for years while he was stationed in the Air Force for a few years. Their son just finished his first year at U of A-Fairbanks. I heard about the Iron Dog in the 2008 presidential campaign and decided to check it out this year. I was all into it and followed it all week. I was pulling for Todd and Eric or Team Davis. I was pretty impressed with the rookie, Cory Davis. 3rd place is not bad for the first time. I will be following next Feb also. I'm hooked.

It will be really cool if Cat puts forth the same effort to race a 4-stroke that they do with the 2-strokes. If that turns out to be the case then there is a very good chance that a 4-stroke could make the podium for the first time. in the past there have been Yamaha 4-strokes raced in the Iron Dog but the teams didn't have the same level of support that the other OEM's offer their teams. Plus, none of the top riders were riding 4-strokes.

Cory Davis is an excellent sno-x and XC racer who rode with his 7 time champ father. He will only get faster as he gains experience. It would be cool if the father and son run it together again for '12.

The main disadvantages of the 4-strokes will be the extra weight and getting them started at -40 degree temperatures. The weight issue may not be that big of a deal since the Twin Spar was not the lightest chassis for a 2-stroke. In the past the 4-stroke racers got their sleds started so that may not be a big issue either. I wouldn't want to sink a 4-stroke in the water, but with all the 2-stroke sleds being fuel injected and having all types of electronics and sensors, sinking in water may not be a big issue either.

The 2012 Pro Class rule changes were announced 2 days ago.

The Arctic Cat F 1100 (non-turbo versions) have been approved for the 2012 race.

Excellent find! This is exciting, I wonder how many teams will run the 1100? I hope its not like the first year with the Nytro. There were around 3-5 teams on Nytros and none of them did very well.

In theory the 1100 should be an excellent choice for the race. If it does good on gas, handles and rides well, it should not be a disadvantage. It will be curious to see how many Cat teams run the sled. I'd rather run an 1100 than a Sno-Pro 600 in the Dog. Just seems like it with EFI and the ability to run on old, low octane gas that it would be much easier to live with.
