Dynotech Test of 850

[Rotax_Kid]

Spun 170.4hp..torque and RPM unknown. Motor is apparently out of break in as it has a few miles on it. Pretty decent numbers, can't complain too much on that.

That's impressive have to log on and see if they post the chart. Be curious to see the curve

I don't see anything posted on the subscription page about the dyno run results. Where did you find this information on the website ?

Read this over on Dootalk. A dealer brought a demo sled in last night for a private run and posted it to their facebook page. It didn't sound as though Dynotech was going to post the sheet. Dealers name is Arctic Adventure. Motor built 111 ft*Lbs of torque

looks like dynotech will be posting the graph on their site today. here's the facebook page for arctic adventures

now lets see one with a "hot" ecm tune!

Sheeeeiiiit now there you go spoiling all my math. Daffy Duck is now only 70 horsepower behind the leader, not the 75 I reported earlier. Oh well, maybe next year you guys'll get a stronger mill.

It's up now on jims site. At dynotech 170.4

called Jim to get his feel on this baby before calling the dealer to order..

he says air for dyno session was very humid and replaces oxygen, also said fairly warm 50f weather...

he's pretty happy with those numbers and once some timing is added and lower humidity he sees an additional gain for the 850..

keep in in mind now this is the same dyno that gives the new poo ho motor a number of 154.9, the 16 Etec 800 a number of 163.6

also mentioned how smooth this motor was to dyno and some runs were back to back to back..

Good job doo..

It would be nice to know the difference in density altitude from all 3 of those tests too

They need to run this, an 800 etec, and an axys all the same day for these numbers to mean anything. It's already been pointed out. They had an etec run 163... we don't even know what the ptek had by comparison. I feel Dynotech should know how to do a fair comparison. Why they have no interest in producing meaningful results is a mystery to me.

Whop whop whop we have a new motor hype. This is just part of the greatest sled hype debte.
Need all 4 sleds (Cat Poo Doo Yami) and lets do some pulls on the dyno on the same day!
Throw in a 16 Doo just for the hell of it.
I posted this once before on the multitude of threads going on - but hey that would actually make sense.

You could then have at least a brand to brand difference regardless of what the peak numbers where - you would have at least the difference between each that meant something.
Still on whop whop whop mode though.....shesh! 7 more months of this till the "production" sleds hit snow.....sheeeesh!

I am sure production motors won't be nearly as hot.....gonna be a long 7 months

So negetive Clode, Ya i'm sure it's going to be a weak 145 hp and 80 ft/lbs of torque. Lol! You and LennyR are among the most poopy pants individuals pertaining to the new Summit 850 rollout. I'm asuming your not snowchecking one? lol!

not a poopy pants, every OEM builds hot motors for the pre-season prototypes, production models are detuned for longevity......

Good job doo..

timing will be interesting with new BUDS software interface

Exactly !!!
Every new model year or production motor seems to perform way better second year into production.

Hot engines? This isn't a TA diesel engine where you can add a 100 HP by doing a ECU program change. A NA engine is really quite limited to what you can hotrod. Timing advance ( I'm sure the're going to run max) it will retard in case of detonation. Any late timing will only increase cylinder temp. The air/fuel mix will or should be running at stoichiometric. Slight changes in injector quantity and duration. In the end, it should hold at 165 hp as advertised. Any more will be a bonus.
