So whats the final verdict? Which is better.......the 872 or 880?
Until a true side by side comparison has been done with nothing being altered aside from a BB top end and the builders recommended clutching/gearing, that is like asking how many licks it takes to get to the center of a tootsie roll pop and the answer is the same..."the world may never know"
BOTH motors CLEARLY work and work well when properly set up and both builders have their fan clubs. This topic is running it's course and quickly loosing momentum
amen to a point where a majority of us have lost sight of the big picture, THIS SPORT AS ALL ABOUT HAVING FUNNNNN!!!The bitterness and turd slinging has gone on what I feel to be long enough.
Call the builders, talk to them...ask them your questions and how they differ from others or what makes their product better and weigh it all out...get in touch with folks running different products and see if they'll allow you to try their sled/setup. Slim has already offered and I sure there are plenty of other SHR, TMS, RKT, BMP etc etc product supporters that would be willing to let you make a couple pokes on their machines to get a feel for what their chosen product to capable of.
Personally, I wish there were more people on here like swrev and mad minni, those are two dudes who come off as being super humble and a couple cool cats to ride with, each owning the competitors product yet staying positive about the others choice. Lets ALL learn from these two!
As for me and my SHR880, I had a flawless season and think I've to the clutching darn near spot on...unfortunately, my season pretty much needs to come to it's end since work is picking up and the Road Glide needs to come outta the basement and the XRS take it's place, but come next year I hope to frequent the mountains more often and for extended stays and would be more than happy to let anyone run my machine or have some FUN hill races!!!
Now lets all just settle on this...SUMMITS are still the best mountain sleds

16 pgs and still no pics of Mini's or Scrat's girlfriends. As far as I'm concerned they've contributed nothing to this thread,haha! Mini's gf did just leave my house though. Better watch out Mini, I know my boy is pretty smooth and may start putting on the moves.
Here are some pics of what happens when you give an old man a big bore. These were some crappy cell phone pics I took when in West for the Expo weekend. They really don't do the hill justice, but I was sure proud of my old man for holding on (he's got 7 vertebrae fused together in his back from a snowmobile accident in Cooke in '95). He was going to show me up. My track is the lower one. I was going to do a re-entry (I think that is the term) but didn't commit, trees would have been getting me if it wasn't perfect. He thought I was trying to climb and show me how it's done. He launched in the air, whipped sideways, and stuck it on the landing. Wished I would have had video. Youth and talent have nothing on age and treachery!!
Hope everyone else is as lucky as I am for having such a great group of guys to ride w/. It's awesome watching a Grandpa hang w/ most younger riders and willing to try about anything.
Big bores do make a difference even at 10,000 ft. You should have seen Zatch wonder what the hell was going on when my kid's grandpa was climbing higher than he could. He didn't realize the old man was running an 860 back then. His sled also was running a 162 track, but tunnel said 154. 860 was the only sled on the trip that could even think about going anywhere near where mini and I were going on our turbo's.

Winning is more like it
From many of your baseless claims...
"at 10k the difference from stock and BB becomes very minimal"
this one is priceless...THATS when the difference is the LARGEST
LOL...you said that out loud....LOL....wow...speaks volumes...
At the END OF THE DAY...if an 872 guy made this same thread and ALL of the 880 guys gave the same LAME excuses as all ya all...sigh
just like ALL threads...a few apples spoil the bunch...BJ
Today in utah 9,500 ft... 3 different stock xm's could not even get into Shute... You can see where they powered out... 880 went over the top... And it's a steep one... Haven't touched it all because of avy... Doesn't get any sun.. 880 might not win every drag race but man put a load on it damn.. Might of sold a few motors for you today john.
As said by BJ. The 880 at 10K is where she really shows her stregnth. After 6 years on the 880s running well 21 motors/ combinations I conclude there is more going on than just a larger bore, Since the crankcase volume remains unchanged the motor has a capability to pack more air into the cylinder than a typical motor. There are compression tests which are basically static and then there are running compression ratio factors and this is where the 880 drastically changes the game, The altitude effects are not escalated when setup correctly, My side by side climbs with many T -Pro 800,s at 8500 ft were a suprise to the losers every time, Granted i run a 3 inch but the motor does not suffer. My clickers at 7500ft with rpm 8200 never need touched even at 10K running the same 8200 rpm. This was not seen on my 860,s or previous Trygstad 880.,s.where I had to adjust to maintain optimum rpm,s The intake signal/pulse is extreamly strong and allowed 15 pilots as well.The stronger the vacuum signal relates to smaller main jets required for delivering the same ratio of air/fuel.However its not just the bore size, Its the porting ,compresion,squish,pipe pressure ect all working in unison , Every components needs to be done correctly to achieve this performance. Then there is this subject of Builder support/service! Another topic all together. This is not a pissing match and for you dis believers that no problem at all. And as another post stated some BB,s dont run any better than a stocker at elevation. I totally agree , some dont,,,Highlight the one sentence that falls into the category of "whining"??

Hilarious I did not expect anything less..... SHR say's "THATS when the difference is the LARGEST"....
Come on you have to be kidding. Just because the throttle response on a BB is snappier than stock does not mean the track speed at 10,000 feet in deep powder will results in any major gains in track speed.
Most BB's and I'm sure yours is no different will produces approx. 8 to 10 hp more than a good running stocker at the Crank @ Sea Level. From the clutch back to the track clutching, gearing & suspension setup determines how well your BB performs in deep powder at any high altitude elevation the same applies to my a Stock XM.
Both the BB motor and Stock XM motor have the same issues at 10K "Lack Of AIR" . Everyone know Air + Fuel = HP....At 10000 feet my Stock XM puts out approx. 115 HP +/- at the crank while BB XM can produce up to 125 HP +/- at the crank @ 10000 feet
Granted the argument can be made that 10 extra hp at the crank is 10 extra hp. In real world high altitude deep snow riding the 10 HP difference between a Stock XM and a BB XM's track speed at a 115 hp and a 125 hp is minimal.

I hope when you post dumb $hit like this that its because you're quite drunk. Otherwise it would mean that you're just not that experienced, or not that clever, and either would be unfortunate for you.

DPG I run a pair of 872s. The diff at any altitude is pretty dramatic. Side by side with stock XMs the 872 goes easily where the stocker either can't make it or has to work really, really hard or has to have a much better rider to get there. You need to ride one yourself before you get to have an opinion that matters, and a modern ETEC or PTEC big bore.
