LOL! You should have him bring it back again for the super-tune! See how many times you can make it run stronger by doing nothing.
Must have been the placebo effect.
Ouch, 12 large? You're getting raped.
Like on guy said 90% of poeple can't ride them at their full potential,
so if 142 HP is not enough then maybe they should go back riding a 600 and when they can ride it pinned all day then maybe an 800 should be in their garage.

There have been some interesting points made.
If the Polaris 700 was putting out roughly the same HP, it begs to question why they didn't stick with that motor? The 700 has been a strong reliable motor ever since its inseption. In 07 the 700 was beating up on other brands 800's.
So, why eliminate a proven motor that would work even better in a lighter chassis? And instead go with a new once again unproven motor? People can say all they want about how the new motor feels. We heard it all before when we snowchecked the 08 800's. The song remains the same. It won't be until you get the production models that you will know how these really work.
Polaris hasn't been having much luck with a reliable 800 motor design. This was the big complaint with the dragon's. Most stated that they would sacrifice some HP if they could get them to stay together. Perhaps that is what they did.
If the motor holds together and runs strong, the HP numbers won't even be a thought in the back of your minds. It's all about riding and having fun. If this sled gets Polaris back to doing that instead of constantly working on the sled and waiting for parts. Then I think some of you will be very happy with what ever #'s they are.

Interesting read. 90% can't ride to full potential, dishonest service? Sounds like the snowmobile industry is full of a bunch of poor riding knuckleheads’.
I will add my two cents, I think Dyno Jim is pretty fair when it comes to his work and what he tries to provide. I'm 99% sure that his results are his honest results. What do they mean well that is the real question? He is the only one providing this kind of information and he is really good at making sure the reader has as much information to at least provide some judgment of what it means, like the air temp it was ran at, the pipe temp the fuel conditions. the air box hook up etc. Does it mean that you will see exactly what his test shows on the snow at 30 degrees or at 10,000 ft, not likly!
My D8 ran like sh## at the elevation I ride at but when I took it to over 8000 ft it was the first time I really got to see what it could do. So there are things to consider. That however is not a good excuse considering it is a fuel injected sled that should be able to compensate for altitude.
Very comment I have seen on the RMK-Pro does seem to support the dyno numbers to a degree; in all, the big comment seemed to center around the midrange being very strong and that did show up. Other comments I heard personally were that the top end seemed very similar. Again that is supported. So maybe there is something to this.
Why are people skeptical, because Polaris gave them a reason to be? The last few yrs have not bee stellar yrs for Polaris owner. I have owned a lot of sleds including a 95 600 XCR, 97 700RMK and an 03 Vertical Escape. All Great, Great sleds and I own a 08 800 Dragon, mine not so great. I will also own an 11 RMK-Pro. The motor had better run better than my 08 D8 and my 97, and 99 700’s. And if the Motor runs better than better than my 03 VE did, that is all that it will take to make me happy.

I am good with all of this, BUT, I still say that most people do not remember this was a 1700 mile dealer abused non RMK motor....and compare HP numbers with other fresh motors...since I have dyno experience...I feel safe in saying that same motor would have made more HP if it was fresh....Dyno Jim, do you agree????

Someone post Dynotech's numbers for the 700, please.
The number won't be 140 for the 700. Let's get Dynotech's 700 run posted. Need to compare real numbers, not speculation.

Because that 800 has so much more potential. Polaris just hasn't put out that potential straight out of the box. I've had both the D7 and D8. Before the PCV and head/pipe mod, my D7 was very close to the D8 except in low end torque. But it would never touch it after I even added the PCV (simple fuel control). I have yet to burn down a Polaris motor since my 99 RMK went down because the rope pull knot broke the water pump belt!
130 to 140 stock without and with a fuel controller. I'm thinkin' the 700 was never 140hp "stock".
Sorry guys,
I never intended this to be an arguement. I was just pointing out that some statements made by others had merit. I don't like doing this, because some of you should subscribe to dynotech yourselves, but in a nutshell the 07D7 made 139.8 in stock form. A BMP pipe mod and boondocker box put it at 147.7. Which I think a PCV would easily achieve. Sounds pretty in the ball park to me. Especially knowing the reliability of the 700 dwarfs any recent Polaris 800's.
BugIto is correct. The 800 was bleeding potential. Unfortunately, we are in the age of EPA standards so a stock Polaris 800 will never achieve that potential. Nor will it achieve the reliability. Remember, an 800 is an 800 no matter how you look at it. If it isn't fueled properly you are going to have issues. I think all of you should just figure a PCV in the cost of your new sled. It is the only way your are going to truely see that potential in a Polaris sled. What Polaris was doing to meet EPA standards with the old 800 was downright scary and it showed in an unacceptable number of failures over the last 3 years. It is safe to say they still don't have it figured out.
I assume you all buy a sled with the intent to ride it. That isn't what the old 800 accomplished. It took the fun out of riding for many and kept people from riding because of failures and down time. And Cardiac Kid, they should be giving you a new sled after all you went through.
I will say it again. Polaris is out to make this thing reliable so that you can have fun on your new sled and that is what it's about. My original point whether it meant they should have kept the 700 or not was simply that if the Polaris 700 was capable of running with 800's than an 800 slightly down on power in a light efficient chassis is going to be just fine if it achieves reliability. So, we probably shouldn't be judging the book by it's cover just yet.

Hey Polaris, I will never buy a sled from you guys again. 08 D8 1800 miles 4th set of pistons, 3rd cyl, 2nd crank / cases, head, CDI, VR, pipe temp sensor. Just had 2010 "update" done now I get 4 MPG, 7400 RPM max on climbs. Many others in my area have had the same problems. My dealer has been great but they can't even get Polaris to help figure out the problems. Polaris had me fooled though. I thought that Polaris couldn't afford to have another roach engine after previous 800, and 900 problem engines. I'm very skeptical about this "new" engine and will be looking at SD or AC for my next sled purchase. I do love my chassis though. Maybe I'll figure out how to drop an E-Tec in there!
I don't blame you for being skeptical and it's true they can't afford to have another bad engine. I don't think the engine is bad mechanically but rather they can't get the fuel delivery issue sorted out to satisfy the EPA. Now they are being overly cautious so power may be down because of it. Ever thought about getting the 660 kit instead? That is the way to go in my opinion.

What's the point of posting this? Are you trying to hurt Polaris' feelings? You swear to never buy another Polaris. Well, until the end of your post where you think about buying the chassis and putting in an unproven motor.
I think what is most important is dynoing all the brands on the same dyno. Whether the numbers are high or low, they will be that way across the board.
If the spread is 20 HP, its 20 HP.
