Got my new snow tech, all numbers are from SLP's dyno

DRAGON
139.1 HP @ 8100
91.5 ft lbs @ 7800 but maintains 90+ from 7600-8100

06 "755"
138.5 HP @ 7500
99 ft lbs @ 7200

Numbers are pretty damn close, put the 755 on a diet and it could give the Dragon a run :div20: , I'm am bias however :beer:

Th enew Doo 800R was in there too, its a beast!!!!!

"800R"
149.6HP @ 8100
97.3 ft lbs @ 7900

I have this issue and I did not see these numbers in the mag. I do not think there is another issue out yet but I could be wrong. I have seen numbers like this but I do not believe they were "official numbers"

It is in the Oct/Nov 2006 SnowTech, You can't miss it, there are big red letters on the cover that say DYNO TEST 800R Powertek and Dragon 700HO CFI

That's a nice number, good to see!

Hmmm, I was hoping to see it crack 140HP in stock form, though I suppose it might if the motor was run at sea level. I'm also curious to see if it responds to little tweaks as well as the 600 does. If so, it will be something for the F8 and Doo 800 guys to think about.

I bet this dyno testing was done with a prototype, I think when they fine tune the mapping on the production
models you will see 140 or alittle above. I do not know this for a fact, but that is what I'm betting.

My wife says that I should not be betting. That just gets me in trouble.

:banana:

I always seem to get my Sno Tech mag late. I have not got this issue yet. I only got the shitty September issue so far. That September issue might have been their worst issue ever. This was suprising because it is such a good publication. I guess even the best have a bad day.

The dyno numbers are good news. Now the big question is if the Dragon is going to weigh the 470 LBS Polaris claims. Weights are usually exagerated from all manufactures lets hope Polars' claims are spot on.

I am still anxious about the delivery dates of the Dragon.

These appear to be numbers to base the turn around of Polaris on!! These and the #'s from the 600 HO CFI.

Add how good the new IQ sleds are looking and the great comments on the chassis and it looks like Polaris has begun to build the foundation for the future.

Make the 700 a full season model - we know this is coming and then add the following. A Pro-X style version of the IQ and a big bore motor (either 2 or 4 stroke).

On the Ski Doo 800 "R". I believe this motor is ONLY available in the Summits as their set up for high elevation and will not live long at sea level.

Yes these r proto-types that were dynoed.Wait until the sleds come out with different fuel curves and ECU programed properly.There's still some fine tunning to do and 139.1 HP is a very good number to start.Just look at the 2007 IQ 600 CFI,it gets 129 HP(spam).I bet u will see around 140 to 145 out of these 700 CFI mills,spam will have them soon enough boys. :div20:

They also said that the motor was not broken in yet and some gains would be expected - how much, they didnt say. It will probably be 140+hp for the Dragon.

Also the Skidoo 800R was dynoed with the break-in chip still in function so the timing was slightly retarded and more power would be expected when the chip was disabled, it will probably be more than the 151hp Ski-doo is advertising with.

Torque numbers for Ski-doo not that impressive or is it just me?

:banana: Pre-production 700cc Dragon IQ & RMK engine developed certified 148 cHP, final production HP ???

Large crankcase transfer ports, cylinder has very impressive porting, nothing but large porting holes!!!
The crankcase has the much improve crankshaft, all bearings are larger, larger PTO shaft, mag shaft, thicker & new larger dia rod base bearing, etc. Very impressive & compact engine.

:cn: The new very heavy duty 700cc Dragon crankcase can now easily handle the M.Y. 08??? 800cc monoblock engine, HP????, I can not tell preproduction HP???

:banana: Production IQ 600cc CFI engine certified 129.6 cHP & non-certified 134 HP at 0 deg F.!!!

The 600cc & 700cc CFI Polaris engine projects have been by far the best, smoothest & most reliable engine projects ran at Polaris.

Polaris retired engine genius Hendrix has been doing consulting work for Polaris!!!!!!!

Where do you get your info? Do you work up in Roseau. This sounds like some insider info.

Polaris must have a hard time keeping this level of confidential info within thier walls.

What exactly are you trying to say here? You have actully seen dyno numbers as high as 148 hp for the 700 cfi. Where did u hear this. This is very good news!

I do not know any Polaris employees.
I think Polaris wants this great news leaked out on their excellent new engines???
Should help increase sled sales. How many Polaris adds have you seen in mags?

I did not see the Polaris dyno sheets, most likely typical production 700cc Dragon would be 142 to 145 HP (just like I posted last spring), hope 148 HP???
The source is very very good, she said that I would be very pleased with my 700cc Dragon.

When I hear of clutching tips, small & large engine mods, I will post.
I would like to find out what minor changes (if any) may have reduced the final production HP.

Last spring SLP told me that their new 700 pipe would be +10 HP, now SLP’s catalog indicates + 6 HP? So 139+6 + 145 HP??? SLP has not posted any dyno sheets???

Sounds like there will be a higher HP flat-lander pipe (not SLP) & etc, not just a high torque SLP mountain pipe available??? More low end torque will just spin the track! My old heavy modified 03 700cc SKS with a 144” x 1.25” track will just leave 4” deep trenches on hard pack trails at any lower speeds. So the short 121”x 1.25” 700cc Dragon will not need any more low end torque!

That sounds good. Thanks for the info. All the dragon owners have to help each other dial thease things in once the snow flies. I cant wait

I'm a little lost here rich03sks700.

Are the 142-145 h.p. #'s something that someone confirmed? Or something that you are just speculating? Where did you come up with the 148 h.p.? Wishfull thinking or #'s they were getting out of the sled but are backing them down for production? Did they actually see 148 h.p. somewhere?

I caught some info on another site that says they are working on 20 dragons in Alaska right now trying to get them dialed in. Heard they are trying different pistins in them right now to see if they can get more out of them.

I don't want #'s that result from a pipe. I'm looking for bone stock #'s.

20some Dragons are in Alaska right now for final confirmation testing. It's my hunch that they'll test right up until the CPU needs to be programmed for production. A new piston has increased the 700's output to over 140hp. It'll also walk an F7 with ease. Good news, cause I doubt the new Cat F8 will be as fast as the skinny and lightweight F7.

That would be great to see over 140hp in stock form from the 700 Dragon.. but the statement about walking a f7 with ease is a HUGE statement! Considering no production sleds have come off the assembly line that's quite the assumption.. Don't get me wrong I would grin ear to ear if this winter all we hear is the 700 dragon eats those F7's up but I wouldn't want to get my hopes up until snow flies! :div20:

over 140hp this is gonna be a great winter bring it on!! :banana:

No need to keep my hopes up. It's a reality.

No bashing intended but how would they know which sleds it can beat when there testing ? Do they buy a sled from the other manufactures so they can run against them ????

Actually all of the manufacturers buy the others sleds. gotta test against something

Actually, they give each-other sleds... or they did anyways. I know Cat and Poo used to swap sleds regularly.

Poo has a large test track behind their Roseau facility and we have seem all brands on the track and in their outside storage area. As said above, you gotta test against them all to stay competetive.

It'll also walk an F7 with ease. Good news, cause I doubt the new Cat F8 will be as fast as the skinny and lightweight F7.

Beating an F7 with ease is bar talk. The F7 has proven they are the bad ass sled. No bashing I give them there due. Have a 700 Dragan on the way and if I can beat the F7 period I am one happy camper.

Hey rich03sks700,

I still haven't heard any reply from a little earlier in this thread.

Yes I too would like to know where you got thoes numbers from rich03sks700 please fill us in.

Me too ... I love those 600 numbers

I have not heard of any 700 Dragon HP numbers from adding after market pipe, pipes or air inlet improvements.

:div20: My 600 & 700 CFI HP source is a no BS person that has worked with several Polaris engineers & mangers. Last spring I had heard from other very good sources 700 Dragon 142 / 144 HP.

:div20: The 600 CFI developed 129.7 HPc per spam.
:div20: From a good source a non certified/adjusted 134 HP at 0 deg F in a cold room engine test.

:beerchug: Rumor, the 700 Dragon smokes F7 Cats bad, not even a close race.

:frech32: T.T. told Poo engineers if there was a problem with just one of ten final production Dragon engines in the 100 hour endurance test, he would pull the plug on the Dragon and they would all be gone!!!!
The "good news" is not one problem in the 100 hour engine endurance test!!!

The rumor of additional HP from a piston change is very possible. In the past removing the piston coating on 440 Polaris heavy mod race engine added 3 HP on a good dyno. So all Polaris would have to due is use a strong cleaner to remove the Grafi coating from production pistons. This coating is not now required on the 700 CFI pistons for cold start protection.

Rumor; the bad news is they are working on a primary clutch issue and improving the air inlet for more HP. Possibility that mid Dec will be the Dragon production date????

I do not think a mid year release of the 800cc Dragon is possible. Would like to see 800cc Dragon proto type sleds out for show & tell.

144 hp good, mid december production date bad very bad. I want to belive some things you say and not others. lol

So far nothing but good from Polaris camp,their very positive about the Dragon.Lets hope.

I will be at the factory the first day of 121 Dragon build, that date is Nov. 30th. RMK dragon's are starting to be built next week.

Actually the first day of the 121 dragon build is november 27 and runs 2 weeks untill december 8.

You're right, an F8, at 539 lbs as delivered off the showroom floor ain't gonna be no speed demon.

Elko doesn't vend the 700's pistons. I don't know who does, but I'd like to find out. There's a fresh set of 660 cylinders sitting in the garage right now and I'd like to know it it would be worth my while to order up a set.

Action Figure Joe, if I had a 600 Polaris it would have a 660 kit with Polaris 700 pistons, remove the Grafil coating on the O.D. & have Swain ceramic coat the domes. Plus install a Struthers/LRM or SLP single pipe, approx 150 HP?? LRM pulls 162+ HP from a mod Polaris 660 big bore & 155+ HP from a 600cc engine.

I called my brother he sold his last set of Wiseco pistons last year, approx $110 per piston with rings & wrist pins. He installed a set of Wiseco pistons in a very fast 1997 Polaris XC that had the 220 style cylinders with the large square exhaust ports, high compression heads, HSP pipe, several years ago. Still running strong 4000+ miles no ring or piston problems! Of course as you know the down side is the Wiseco pistons have low silicon content, require .004/.005” clearance or they usually tighten up in the cylinder. My brother likes Wiseco pistons. Has has installed in many engines with out any problems, but with proper clearance. However I do not like Wiseco pistons in a mod engine, such as a full mod 500cc Suzuki Quad race engine. That I had to install the Suzuki large ring stop pins in a Wiseco piston, then excellent.

My brother sold his last set of 700cc Polaris SPI pistons with 2 rings last spring for approx $80 per piston. He usually prefers to install SPI pistons, not one problem, reliability, performance & cost. Brother even tried to talk Larry R. to try SPI pistons, due to high cost of Polaris pistons. LRM has his own special 440 pistons made for him, but high cost.

I think Cudney Racing & several other shops use the two ring SPI pistons in their Ski-Doo big bore kits. Much improved performance in a heat soaked engine & reliability. The single ring Doo pistons loose a lot of HP when heat soaked & reliability issue.

I believe that ELKO makes Polaris & other OEM pistons?

If it was me & had lots of $$$ I would have my brother call Wahl Brothers Racing or Burt at Pro 5 for three new Poo 700cc pistons, Poo Gaskets & etc. Then build a 210 HP triple cylinder 1050cc engine. That is if I had a 03 700cc SKS, Pro X or XC. A triple is too wide to clear this years Dragon’s shock towers, next year???

My brother is too busy to do 660 kits. He suggested not to raise the exhaust port height on a 06 Polaris HO 600cc cylinder. If older Poo 600cc cylinders are used then have my brother port to the LRM porting spec that Larry R. developed for Jack Struthers, Carl’s 660 kit is the best!!! Good Luck; Rich

This is my third 660 kit. I had Eric Gorr do my first. The second and third I did my self. The second kit is still running strong. I'll be using SPI pistons with a leftover set of OEM rings along with a Legend head. That is if I keep the kit. Might sell. I've got three weeks to make up my mind. The 600HO is damn strong as it is.

I don't know where you got your info but Larry did not develop the porting specs for Struthers 660, Jack used his pipe but Jacks porting specs are his own.

About two or three years ago my brother told me that LRM modified his LRM 700 Poo single pipe to work on a 660 BB Poo. Also said that LRM gave Struthers the 660 porting spec’s that he developed the pipe for.
Yes I would think that Struthers has improved the 660 porting in the last three years.

The reason Struthers (Carl's) has the best 660 Poo BB kit is he does all of the engine work, best pipe, carb set up & the best clutch kit, the best total package.

Don't like the SPI rings?

I can't say anything bad about SPI rings. I do know they require a fair of ring end filing. The OEM rings were a perfect fit out of the wrapper. I had an extra set so I'm using them.

Why does the Grafal hurt performance. I am installing a new set in the next couple of weeks. Should I remove the Grafal. Also, what are SPI pistons? Maybe I should swap for them?

I've heard comments about the grafal coated pistons, BUT it was in relation to use in race motors only. The comment was that the coating seemed to make it more difficult to get the rings to seat the rings properly. In a small bore race motor with narrow, low friction rings, I could see it being difficult to make rings seat properly. If the rings don't seat well, the motor will be down on power. To make matters worse, a fresh engine doesn't get much time put on it before it goes out on the track. Everything has to settle in and be ready to run quickly. If uncoated pistons were free HP for your trail motor, that information would have been out there years ago and there would be shops promoting their "coating removal service".
