Let's start clearing this up a bit better. Carlc, the Super your referring to is a Cat right, not a Polaris?
The sled I rode was a Cat, no questioning the fuel consumption. I spent enough time on a sled to know the difference, this is one thirsty unit. Was it as lean as it could be? Definitely not, but it wasn't puking fuel out the exhaust like many other sleds I seen.
Definitely was rich off the bottom and it made it easy to flood. Was a set technique to clear out the unburnt fuel if it didn't catch first pull or two. Nothing magical, just a couple pulls with the kill switch on. Then it would fire with just off idle throttle. It wasn't flawless and hard at times for people not used to pulling over big blocks like the 1000's on their own. If anything was to blame here it would be pointed a the Power Commander for complication of use over quick adjustability due to the need of the laptop.
If a sled is empty next to another that only burnt 1/2 a tank, I can assure you it's thirsty. Running a TM1200 race gas, TM8 race gas/propane, XM and an M1000, got a good base platform to understand fuel consumption in the Mountains with alot of other friends in the group running stock machines for comparison. As mentioned if you read clearly, the exact same setup Proclimb from his brothers unit was in the trailer we rode the second day running just a pipe setup. No comparison, only other sled I seen burn this much fuel was a Supercharged Apex. I'm sure you could get a 50mile deep pow day, but not riding the way I ride and weighing 250lbs geared up.
I don't think the super was any harder to start than my TM1200, easier if anything for sure. Just hard to pull and crack the throttle at the same time if your not used to pulling a 1000+cc sled over. Cracking the throttle makes a huge difference in relieving the compression to aid in starting, and in the case of the Super we rode with Speedwerx tuning, to clean it up to fire easier and spin over faster.
There is a difference in between the SC800 and my TM1200 in the bottom end. The SC800 feels more electric and smooth like a 4 stroke. The 1200 is more a torque effect after the belt is engaged and rolling like 10-15mph. The SC800 is like right at engagement and makes a difference in how little it will smoke the belt as a result. It's not like it surges or pulses like a typical 2 stroke at engagement coming off an on all the time. it's like you could hold it right at clutch engagement so smoothly and hold it there. BUT! You need good traction. You need it to tame the instant torque it can apply to the track or it will spin until you've gained enough momentum to find new traction.
We rode the SC the first day, then the piped Proclimb the next day, and SC again the last day. Really good reference and the conditions stayed the same all 3 days. The XM never touched it's reserve fuel, neither did the Piped ProClimb. Everyday we took the SC out it needed fuel and burnt up every bit it had flashing reserve back to the truck.
The owner snowchecked a new 2016 from SpeedWerx through Jeremy, it will be interesting to spend more time with that unit next season no doubt. It really was amazing how well it ran on the bottom end especially locally around 1000ft elevation. Definitely alot better than my Turbo's on many levels.
