Here's what we know after todays DRAGON 800SP Dyno session at DYNOPORT

Rich is under contract to AMSNOW who will publish his results in about a months time if not a bit longer so he's not throwing out exact #'s

in comparison to DTR's STOCK HP #'s, Rich mentioned Jim's #'s were not out of line ( that's doing POLARIS a favor )

Rich said there's allot of potential with this sled but it's going to take some $. He was hoping to see it closer to the XP but it's not - at all


our sled is being prep'd as we type, had we had this information from DYNOPORT on Monday, it would be staying at the dealers - that's how well the Dyno session went today at DYNOPORT

we'll make the best of it

Stay 'tuned'


DYNOPORT Product Update
PS: anyone wanting a DYNOPORT XP Single Pipe and/and or Y pipe Rich advises to get on a list because they just ran out and wont' be getting anymore in until mid November - Canadian's can order through us

I'm guessing its down in the high 130's...
Maybe Casey's was a ringer??

Rich was dyno testing w/ Tstat in, he hadn't renewed his subscription to DTR so he didn't know how to deal with the temperature/ octane issues we had (just kidding Rich)...

He has 110 lb/hr fuel flow and 120 degree F coolant, you can see those results on DTR. Rich's dyno is calibrated properly like mine is.

again Rich wouldn't say and I respected that - if you were asking us to guess from how he described the session it would be more in line with what that Quebec shop found and that's about a HP or 2 more than the stock NYTRO ( you can do the math )

strange how these independent dyno facilities keep getting bad sleds ??

and yes Jim, Rich had the info from your blog.

our concern, anyone trying to get anywhere close to what Polaris has advertised as stock HP , will have to void the warranty doing so

nothing on my website should do anything to void warranties. I think, and this is an semieducated guess, that the Dragon 800 detonation protection is the best so far. Overprotective, yes, but a slow running sled with timing knocked out of it, and fuel added because of someone running poor gas at high coolant temp is way better than a squeeked piston and a tow-job.

Run cool, run decent fuel, and you can run on the edge. Any 800 twin over 150 HP is on the edge in my opinion. That det protection is your friend, whether you know it or not. Just avoid using it, with cool coolant and decent gas, and you can run leaner with more HP.

OK..i'll be the first to type..'WE DONT RACE DYNO'S"


THIS IS BETTER THAN READING THE full 110 pages of text for "The Emergency Economic Stabilization Act of 2008"

I have been reading the crap you've been spewing for the leat 2 weeks, and something is abundantly clear.........


Your trying to sell everybody that believes your BS, a fix!

Well SWR, some of us have been telling the truth all along......so there will be no problem accepting these numbers here. In fact, there are a lot of posters on here that have some crow to eat for all the bashing they have sent my way since I presented my original ride report on here about the 09 800 way back in March.
Damn, I hate being right all the time. LOL

Bottom line. Those of you who defend Polaris for their horsepower claims on this sled are doing us all a disfavor. You are only encouraging them to continue selling us less for more. Think about it.

i have a subscription to amsnow and on there website they claim the 800 cfi made 159 hp. Does any one know who actually made the dyno run? How are they going to expalin the fact that all of a sudden its down to 140?
http://www.amsnow.com/sno/default.aspx?c=a&id=3851
snowtech seemed to think that this sled was strong same with supetrax and snowgoer.
all of the things i read about the 800 (besides for the last two dyno runs) seem to be in favor of it.
I'm sure the sled will be a blast to ride!

LOL Speaking of someone who has a lot of crow to eat.......

when will we know what dino port saur dynoed it at?

One big major factor between this session and DTR is that the polaris guy wasn't there with his laptop making his a ringer, like all other JOE BLOW's will come out of the crate. Crow eating time, time will tell.

Magazine reviews are almost worthless. They give you something to read and that's about it. I enjoy reading them too but I take 99% of it with a grain of salt. Read their reviews of the '05 900 Fusion when it first came out. "Great sled, blah, blah". They were dogs out of the box and needed some money put into them to make them run how they should. After the 900 Fusion was discountinued the same magazines were saying how it was not ready for production, bad calibration, etc., etc. They are nothing but cheerleaders for the big 4. Make your buying decisions off instincts, people you can trust, demo rides, etc. Not the BS marketing and magazine reviews.

I'm not saying this sled will be a dog, and I'm not saying it will be the fastest sled ever made. If you want to be at the front of the pack it will take some minor mods and tuning just like almost every other sled. The '08 Dragon RMK 800 155" prototype I rode in West Yellowstone in the spring of '07 had fuel mapping issues, I can't say I ever honestly expected this sled not to. Not that that makes it acceptable. Just judging from past experiences. The chassis and suspension more than the motor of the new sleds is what makes them better than the old sleds IMO. Compared to my lightly modified 800 VES, the 800 CFI was not that much better from the seat of the pants. It was actually worse out of the hole(bog), midrange was about the same(still not quite as strong as mine, fuel mapping issues again) and it had slightly better WOT pull than my sled. Irregardless of the motor I would take the new sled over my sled because of the chassis and suspension.

On the bold. Just as dyno tests are almost worthless. Which dyno do you believe? I believe in seat of the pants.

^^^^^^^^^
Agreed.

Something doesn't jive here!! Polaris stopped claiming HP on engines for a long time up until now. They were even criticized for not doing so. Why would they risk a lawsuit or Fusion deal if they new it made less HP then advertised? They new without a doubt people would be dynoing them. I realize this question is for Polaris but it makes my point.
It did make me give $20 to Jim so I could look at his results though.

This shit is getting old, just drive the thing. I agree if advertised at 154 it should be close to that +/-2HP or so. Not Less 10HP! Big Fuse and shortstop are right seat of the pants and real life racing f- the dyno, there are to many diff numbers out there that are sto far off from each other.

To clarify, the Polaris guy only monitored Casey's engine with the computer, no reflash was done. All tuning of fuel in Casey's ECU was done with the power Commander. No ringer, unless Casey's dealer got 14 of them. He picked his out of the bunch because it was the one manufactured on his birthday.

Have you guys gotten any opinions from Polairs why these motors are such slugs? I am sure this is embarrasing for them.

^^^^ Wicked man WICKED....How can you say that these motors are slugs? Even if it is not the fastest sled is that all you guys use these machines for is straight lines? I cannot wait until these D8's are walking everything in their class and above. You will all see the Snowflap!

Just wait for the snow to fly and then we'll see what happens.

Just my 2 cents,, but I hope it's faster than the also hyped up XP, because we sure didn't have any problems beating the XP with the stock well setup 700 Edges we ran against them all last year.

Ask Rich if it's +/-2HP off 154HP

the way these sleds are being shipped "IS" a big/HUGE deal -period. For the brand loyal , sure waiting to see how they run in the field compared to the other same class sleds will be the tell all but that's not the point here. Polaris obviously is aware there's problems with this sled, every independent dyno that is testing them has them down 10HP or more. Personally I'm a believer in getting whatever HP is available to the track, so we're looking to see if that will make the difference when compared to other 800 class sleds, we're thinking it will - remaining positive, however that's not taking into consideration this sled is going to be a hog on fuel to boot



try getting a Polaris rep on the phone that doesn't push you off to the dealers who shouldn't be taking the heat on this issue.


we're picking ours up Sat - and we'll get it dialed in, but to what $$ expense we won't know for awhile, regardless of what expense that may be that shouldn't happen! As far as our thoughts on mods at this time given what we've seen in dyno testing - SLP single pipe set with silencer/y pipe and main pipe, SLP Hi Flow Intake Kit, HOLZ shock tower and footwell vents, BOYESEN Rage Cages, Change out for Royal Purlple Snow 2-C and most likely a change in plugs to NGK Iridium - and of course endless hours with clutching and gearing. - from what we're hearing from sources we have faith in, that should net somewhere around what POLARIS is advertising for HP


just my 2 cents
enjoy the day

Alot of you are saying "just ride the thing", "it'll rip with the 145 hp". as that is true, just think how much MORE it would rip if it had the advertised hp!! No one is questioning the fact that it will be a great sled with the hp its been dynoing at, however polaris already has a sled in that range of HP....its the 700 Dragon. People have every right to be pissed off about not receiving the advertised HP from Polaris. Polaris is not alone here as other companies have delivered a product that wasnt as advertised (cat saying the 07 F8 will handle the F7's of old easily...we all know that didn't happen very often). I don't care which company it is, it should come as advertised!! We are not dealing with tv infomercials here, this is a big bunch of change that the consumer is dropping and its only right that they get what they pay for!!
I don't get the thought process that dyno numbers mean dick all...the more motor hp you are making the higher the potential hp to the track will be!
Heres to hoping Polaris sends out a bulletin acknowledging the issue and then addressing it!
Good luck to all you who snowchecked one, I hope you guys get the ringers!!

Mig Moe has a D7 and a D8 in his garage a mile from your house. Line em up and put an end to all this bs.

Shortstop20, "Magazine reviews are almost worthless" & Big Fuse, " Just as dyno tests are almost worthless. Which dyno do you believe", are SPOT ON on as usual!

I believe NOTHING American Snowmobiler prints on Polaris usually bad & Ski-doo's way over rated!!!
I CANCELED my subscription to American Snowmobiler a few years back because:

A few years back American Snowmobiler had Dyno Port make several dyno runs on the Ski-Doo 500SS (actually 600cc). They wanted stock HP & then a max modified super lean HP.
---Dyno Port stated to it's customers 105 stock HP & 117 HP full mod HP.
---What did American Snowmobiler print???























American Snowmobiler printed the stock Ski-Doo 500SS made 117 HP on Dyno Port's dyno.
I am sure Dyno Port was not very happy with American Snowmobiler's total BS.
However I must state Dyno Port was very honest on the low 132 HP 08 700 Dragons DOGS.
Guess why I purchased 09 600 CFI Switchback, not the 800 CFI, my 07 D7 DOG???

The 800 CFI's will be fast if one spends $200 on BMP pipe mod. Also mod the air intake to high flow similar to SLP's $60 high Flow kit. On my 09 600CFI S.B I just removed the sponge donut from inside top of the hood, pried of the restrict-or adapter with a 2.5" I.D. Then just re-glued the sponge donut that has a 4.0 " I.D. I did not remove the sponge plastic inserts just under the fine intake screens, then there would be too much intake noise.

Unlike, I spent $2000 (dealer costs) in performance parts to my very slow stock 03 SKS 700 DOG, Then have several top performance shops help in the final tuning, 0 cost. Most 800 XP's would not race this low to the ground 03 SKS 700 heavy mod, efficient skid even stock, 8" big wheels, ect, etc. Yes any good mod sled better smoke a stock poorly set up sled!
LRM told me to remove the thermostat, plug the by-pass hose, add extra Polaris running board cooler, Red Line Water Wetter, etc, etc, as his mod engines make the most HP at 95*F & less chance of burn down...
Happy key board racing; Rich

So, why can the 600 CFI's perform so consistently well but the 700's and 800's suffer from poor mapping? If the 600's produce their 125HP, you would think an extra 23% HP for 33% more displacement would be a very basic expectation.

If it even has just 10hp more than my "130hp" 700 Dragon then the 800 CFI should be the top sled on the snow.

Because 600cc sleds are the bread and butter of the snowmobiling market and they spend more time on them than the larger cc sleds to make sure they're setup good.

Bickering/arguing/brand loyality aside the guys whom were banking on 154 hp got the shaft. Some guys do purchase machines based on HP claims and they were mislead. Its not fair its not right and it should be addressed. At the end of the day none of us want to get screwed over by a manufacturer falling short on their claims no matter what brand we ride.

This season I was informed my yamaha FX Nytro I had last season was never intended at the trail market yet they marketed it towards the rough trail segment this was their excuese for the poor handling.

Hey SWR...What happened to the possibility of getting another sled such as an XP on the Dyno at the same time as the D8? Did that happen? I doubt it will right.
Ok so the sled is low at 145 which Jim reported. I will once again ask and state about Dyno's and their variances. Were these conditions the same and was it the same type of Dyno as when Polaris dynoed in the Spring for the 154 hp? Maybe Dynotech Jim can jump in on this question since he is the tuner here.
I am sure Jim can verify that all Dyno's are different and state if the above questions I asked are factors in these runs. Yes i want the 154 hp Polaris advertised, BUT...Until all conditions are the same as the Spring tested model and as well as when other brands were tested then I am not concerned. As well as testing say an XP at the very same time would be nice.

And Spence that's just my .02

who can agrue that



From the way Rich described yesterdays session you don't want any comparison dyno #'s with the XP - fingers crossed it performs far better in the field than it has on the dyno

For those of you who have not picked up your D8 yet, and for those who were thinking of buying one..(and you were going to leave it stock)........are you still gonna pick it up or still buy one???????????????

Once again the main question is avoided. CONDITIONS AND DYNO'S...Were they all the same? It's a pretty simple question i think and not alot to ask.

Pick mine up tomarrow. If it's a pooch, I'll mod it, if it's still a pooch I'll sell it and get the Z1 turbo sno pro or the XFR 1000 even though my 07 Xfire 1000 gave me trouble maybe this time around Cat will be more reliable.

If I can get 110-115mph out of it and it beats my 08 700 Dragon I'll be happy. We all know it's going to be one of the best riding and handling sleds on the market.

this is true - just feel bad for the guys that may not have the $$ or the ability to make this sled what it can/could/should be out of the crate

Thats my issue..spending Hundreds of $$ if not more than a grand on top of the purchase price to mak eit go.........and do not want void the warranty...AGHHHHHH!!!My HEAd is gonna explode.... I am up in the air about spending the $$ I can still back out..and only lose my $500. Better than buying and then tryin to sell it and lose $2500.

I just got back from the dealership and had a look at mine...VERY NICE. It will not be for about 2.5 weeks before I take mine home though. I have a track swap to do and maybe some other mods.

I pick mine up on Monday and could not be more excited.

I purchased the SLP can with part of my $500 accessory option.

I am anxious to see the performance of the Projector Beam I ordered as well.

As for the delivered HP of the machine. I've been all over the boards looking for opinions on this topic. This site and certain members seem to be the only ones that have negative information.

There seems to be only positive comments about the 800 and it's performance out west last year. If Polaris can please the mountain crowd, it is deffinitley good enough for me.

I picked mine up last Thursday. You can bet your ass I'm keeping it.
I'm a little upset about the HP #'s I can say that.

But I also agree HP is different with different dynos. Plus there are a lot of different factors that can make a sled or break a sled.
People are jummping off the Polaris wagon way to soon.

Also there is HP to the ground. HP to the motor is one thing. HP to the ground is a totally different animal.

I beleive these motors are like any other manufactures motors, there are differences in the power they produce. I have 2 buddies who own 07 F8 and one was faster than the other out of the box and with the same mods one is still faster. The same thing was with their 03 F7s and my F7. One was faster than the others.

Now take my 07 Dragon 700 who many people feel are slow. I did not have a slow one and in most conditions my 7 would beat the above mention F8s with clutching mods. One of my buddies did hand it to me with F1000 diamond drive in but conditions were heavy wet snow and my 1.25 track sucked up much more snow than his 1 inch track.

As BuddyP said in a previous post if the 700 Dragon produces "130HP" and my sled does 110 MPH in good conditions the 800SP at 145 or better should flat out rock. I do beleive my 07 Dragon has more than 130 HP though.

Read all the reports on the XP 800 and the 151 HP. A lot of those sled barely broke 100. These same dyno shops are saying the SkiDoo numbers are accurate as well so it is about how the HP is put to the ground. I never raced a XP with my Dragon but a dam Crossfire 7 is about 3 lengths quicker as are some of the F7s I raced but not by much. Make sense on the F7s since the chasis is meant to go fast.

I have an idea. There has to be some people on this site who have bought 800SPs who live close to these "reputable" dyno shops. I have no reason to beleive the numbers they are getting are not accurate but why not have these dyno shops each offer some free dyno runs on their respective dynos. Put a post up that says the first person who shows up will get free testing of his engine. Only offer it to one person and then you will have an independent rider that is not associated with any of the shops. Just a regular consumer wanting to know what his sled has for HP. This may show some of the inconstencies I am taking about.

Most people who can afford a $10000 sled can usually find a few hundred bucks to give their sled a little treat...most do it anyways. But you shouldnt have to. We all have these sleds and we all face the same issues. How about we put this issue to bed until January when more shops have theirs and we all have ridden them, I for one think it will be fine. Plus, everyone who buys a high perf sled should know that the high performance machines, no matter the brand are all a little finicky...its always been that way. Thats the reason that consumers cant buy the race sleds anymore because they were getting all of this HP out of a 440 in the hands of a person who knew what they were doing and then Joe wannabe Snocrosser gets one and it either doesnt run or it burns down. If this 800 pulled the 154hp and was burning down I am sure nobody would care because the numbers were there right? Poo is being safe for all of the fuel issues in various areas if you ask me.

I'm still picking up mine and have no intention for any mods to the engine, clutching or cooling system.

Some of the information in the various posts is interesting and overall this dyno soap opera is quite entertaining!

As long as spenc comes out with a d8 power commander pre-mapped for 152-153 hp.

Doesn't matter to me anyways I always sell my sled at the end of the season, my nytro was a diaster last year in terms of handling, one thing the d8 has going for it is the awesome suspension setup.

Ya, like that would fly

So if a D7 only has 130 and is hanging with a f8, shit these should flat out rock at 145!

This Dyno soap Opera is getting boring to you...Why? Is it because you understand Dyno's and how they work? Or is it because you dont know the difference and are basing your opinion of the sled on the results we have seen so far?
Dyno's can vary from 5% to 8%. So a 5% variance fron 154 claimed by Polaris is 7.7. So 154-7.7=146.3
And 8% of 154 is 12.32...So 154-12.32=141.68.
So DynoTech's #'s are well within the variance. So if we were to take the sled that Jim dynoed to the same dyno Polaris claimed the 154 hp from, then we should see the 154 or very very close to it according to the variances I just posted.

I am not Brand loyal at all guys. I really like Polaris sleds and they have always made great power for me. I am concerned with this topic because there is only negative info posted with all this Dyno crap and there are too many hidden variables, and yes because it is my sled of choice.
Everyone needs to take some time and search for some info related to Dyno's to understand where I am coming from.

LOL That one's not even worth a penny. And you of all people know better. LOL

You and I both know that there is no way in Hell, a well setup ISR stock 700 edge is gonna have "no problem beating" a well setup ISR stock 800 xp. LOL I'm a little disappointed in you.......keep it apples vs apples. Keep it real people.

I wasn't being sarcastic. My opinion of the sled (including the power) will be formed from riding it.

As far as variance goes, wouldn't the variance be +5-8%. I would expect there to also be some dyno runs that were higher than 154 by 5-8%. The HP could then be stated as the average based on a statistically significant number of runs. Of course this assumes the different dynos are all calibrated and run in exactly the same way. If you want to compare sleds, the best way would be to dyno a number of sleds (D8, XP8, F8, XFR8) on the same dyno on the same day. Then do this with a track dyno and see who's getting the power to the ground (which is the most important thing). Then you would have to do this multiple times with different sleds each time since not all the same sleds are created equal......sounds like an impossible task but maybe Jim is bored and needs something to keep him busy (now I'm being sarcastic).

I like how one guy is stirring the pot about the 07 D7 performance. It is fine to stir the pot, it is fun, but I know the what happened when we lined them up.

You are an idiot Slinkie.
