2010 DRAGON 800 DYNOTEST Stock & PC-5

Thread Rating
5.00 star(s)
Riley- You are correct it is disturbing...maybe after the next update we'll be done to 134 hp...is anyone going to complain then? or just be happy with a reliable engine hahaha. Polaris 800 engines are junk junk junk. Too bad there's no resale value left either on these sleds as there are so many bad ones out there.
 
Just buy a fuel controller and rejet the damn things! This is the future, embrace it or buy something with carbs. As far as the pc 5, a friend brought up a good point and that is what happens when the bosch o2 sensor gos out from being exposed to 2 stroke exhaust. Your autotune is not going to work that well, and people are going to have blind faith in it, sounds like trouble. I will be sticking with attitude industries products. Lean out the top, add fuel in the mid, add some more when your on the n02. pS my original (no updates) 08 D8 is still rockin and rollin.
 
Wow, after 3 years Polaris can't get this right but yet a company with an item in a niche market can produce the correct results to get the proper A/F ratios so that you have a smooth running engine producing the advertized HP numbers. And, to top it off people are complacent and believe that as long as it is reliable (even though it is 10 hp short of the advertized dyno result) Polaris is doing the world a favor.... BS, Polaris has the ability to get us these sleds back to us with the full 154 HP and make it reliable. If not, maybe it is time to advertize the 800 as 144 HP with a $600 "option" AKA the PC-5 auto-tune to upgrade. Just for the record my 09 is pulling reletively the same RPM with no clutching changes from last year with 80 miles and the first tank running about 15 to 1......yes the dealer forgot to mention they had added a quart of oil to the tank even after I asked to varify this before I picked it up so my quart went in the first tank as well. Overall my sled seems to be running alright but these dyno results of 144 HP below 30 degrees are disturbing, especially when the majority of riding occurs at or below this mark. Am I the only one that believes this is a problem???


It is relativily easy to get the right fuel map for good drivabilty and best power. It is another thing altogether to get it meet emissions. This is were all the problems lie. Cat and doo are having problems with it also but just not to the same extent. It sucks but it is the way of the future so the pc or any fuel controller is the way to go in order to get them to run perfect.
 
With that October 19, 2009 test, please keep in mind the extenuating circumstances, it was 50* and they said the E.C.U. fattens up a LOT below 30*

Stock Corrected H.P. was 150.1 actually

Most recent test was in cold weather, E.C.U. apparently "over compensated" and it's down to 144 h.p.:mad:

Is that map available yet for the PC3???
 
I agree with Riley, I left A/C because I was tired of poor performance at higher elevation. Now I buy a 144 HP sled, so I can spend more cash to get my advertised 154 HP, that voids my warranty and you guys think this is right. Its got nothing to do emissions, the thing never had 154, and don't tell me Polaris can not fix this problem for us with reliability and warranty.

P.S. I do like the sled, lots of good points, just want what I bought
 
You know advertised 154 hp is no different than buying a car stereo amplifier that is 200 watts, all it has to do is produce 200 watts of distortion for them to label it. So one of their test motors just has to make a 154 hp pull on a dyno at sea level for them to label it 154.

It really is the consumer's fault that this is how it goes, because everyone is so caught up on numbers that they often use them to make a purchase decision, instead of how well they like the machine and HOW it runs on the hill. The manufacturer has to try and claim everything as high as they can, because you can sure bet their competition will. ( gotta stay competitive )

So if everyone would quit worrying about what the dyno number is ( you can't ride a dyno ) and pay more attention to how it actually performs, then use a dyno to find a little more performance out of their machine, they might find out that they are actually happier!!! No more d**k measuring.

just an observation!!!!!
 
Pc-3 maps, are the same as pc-5 maps

Is that map available yet for the PC3???

PC-5 MAP info just has to be manually typed in with your computer into the PC-3,(takes 2 minutes)

SAME IDENTICAL minus #'s are used in both, just not directlly downloadable, that's all.

I think Jim said it would be available this week, as he was involved with the American Snowmobiler Shoot-Out this past weekend Dyno-ing the stock sleds

It DOES have alot to do with emissions. The manufacturers have to meet the quidelines set out by the epa. Why doe you think that they come with such huge silencers. Theer is alot of engineering that goes into them. Two stoke engines have a hard time getting low HC emissions and four stoke sleds have a hard time getting low NOX emssions. On a four stokes they use egr valves and cam timing to help with NOX. For a two stroke they would use a CAT but the oil in the fuel plugs them up. So they are stuck with triying to run them lean at part throttle to meet the emissions and add alot of fuel at WOT to keep things cool. Tahts were the bog comes from and the piston scuffing issues. Best thing to do is get a fuel controller and reset it your self and you will have no more problems.

Exactly, it has everything to do with emissions. Polaris leaned out the 800 CFI to meet the EPA emissions. The lower injectors are responsible for this job and they also control the fuel at mid range. Mid range burn down? Yeah, it's all relevant.

Hey, I don't like it either. But someone has already proven that they can get 155 HP at sea level with this motor by simply changing the fuel settings. This is not a big bore, porting or some other performance mod. It does cost money, but it's possible.

Go to the Diesel forums...you will see similar complaints about fuel mileage, performance and reliability because of DPF and other emission standards for diesels.
 
As far as the pc 5, a friend brought up a good point and that is what happens when the bosch o2 sensor gos out from being exposed to 2 stroke exhaust.

That's why it is setup to be removed and "capped". The guy who works with DynoJet commented on here about how the auto tune is a diagnostic tool that is meant to help you fine tune your sled. Not neccessarily something that you leave on your sled and it will always be perfect.
 
It is about the emissions but it is also that Polaris had some major cooling system issues on the 08-09 sleds have a look at a 10 and the cooling hoses are all rerouted. The tech that I talked to said that the mid range burn down was more an issue of too much cold coolant and the lean condition which compounded the problem. But the PC V seems really the only option that we have to keep these sleds running properly and to get the horsepower we all want!

As I go flying by on my 600HO carb. Pretty neat huh. My friends 700CFI runs pretty good but my 600HO runs with it and is slightly faster on the groomed.

Good point. A year from now we'll all know for sure whether or not the PC5 is the ultimate answer. In the mean time, expect some glitches, no different than any other new product or technology.
 
I know this is for the pc v but does anyone at all have a map for the pc III for the 2010 800 yet? Would love the pc v but already have a pc III.

Allblowdup,

I talked to Starting Line today and they hope to have a map out for both pc3 and pc5 in a couple of days. Great posts you guys on the emissions thing. Buy an EGT guage with a fuel controller and tune it yourself. I prefer my EGTS over my O-2 sensor because it is 2 feet closer to the flame and gives me small changes in data quicker.
 
I'm going to have to agree with pretty much everything that is being said on here but the point remains.....why should we have to go buy a 350-600 setup just to get these things to run at their potential level. I'm all about supporting after-market companies but this is BS. All this emissions talk, it's most likely part of the problem, but that is BS too. The standards set forth by the government for this seem silly. If everyone that owns a sled started them up and ran them all in one inclosed area the emmisions would most likely be a minute percent of a fossil fuel burning electricity plant. And more on that subject, because of faulty data and ill-informed people, we don't even have global warming anymore, it's now considered climate change because they have no standing evidence that our actions are having even a remote effect on the enviroment.I'm starting to ramble on and on about all things evil but come on, Polaris is an American company and they need to do the American thing and give us something that has an insanse amount of power, smokes like a diesel, and gets 2 miles to the gallon!!!

All things equal, I see your from Michigan and talking about flying by on groomed trails. I'm not trying to be-little anyone here, to each their own and if that's what you enjoy thats great. I'm not looking to go down the trail at 80 and see if I can beat my friends to the next trail marker. I bought my 163 to ride the steep and deep. Find the deepest snow and the nastiest tree ridden, rock strewn, $hit-holes that nobody wants to go find and drop in. This thing is supposed to have the power/track etc... to do that and that's what we all want, from the factory, stock, no installation of some gadget to overide the stock fuel map when it should already be doing the work!!

That is my point. The thing should just flat out rip from the factory stock. That is why most buy an 800. I used to have an 800 and a 700 before that. But this time I bought the 600 because I did not trust CFI yet.

I for one do not liked groomed trails either. We only use them to get out of town to the Deep untouched snow. I was just pointing out there are some issues with these sleds. Thats all.
 
And might add Paul that a 600 at sea level probably runs like an 8 at elevation.
