weight to hp comparisons 2012 cats vs 2012 RMK

[barry1me]

I used the HP numbers for the 2011 PRO that were on the skidoo webpage. Skidoo claimed 163.9hp for the 800 etec, 162hp for the Cat 800, and 152hp for the RMK.

I have raced 2011 M8s and 2010 800R summits and beat them both repeatedly....regardless of what hp the PRO 800 is its beating '162hp cats, and 155hp 800Rs'

 

[Ask Yourself]

The Pro's will once again be King of the Mountains next year.. Just got back from West Yellowstone and all I can say is the new Proclimb M8 is flippin HEAVY and the M1100 turbo is a TANK... A 12 M8 pulls over harder with no fluids in it at all then my Pro does full of fuel, tools, gas and beer... I hope it handles really well cuz, all it has going for it now is strong HP #'s...

king of the meadow swirlys is more like it.LOL.what r you guys smokin?every time i ride with a pro it climbs like a 700 cc sled.

thats funny...I think you should change your name on here to the last of the doohicans......A dieing breed.......

 

[catmanm8]

Mental masturbation.....all dyno tech sleds are short track sleds...are all of the motor parts and air / exhaust the same???? fuel maps the same...then we guess on weight ...lol....I think it's all close....lol

Has anyone seen dynotechs sheets on 2011 model 800 Cats? They aren't 163 on the 2011's...155.9hp on a zero mile 2011 800 Crossfire.

Zero miles on the 800 crossfire? We all know (at least most of us) that a new engine with 0 miles on it is not going to make the advertised HP until break in is complete and there is good piston ring seal (minimal blow-by).

Supposedly there is no "break in" mode on the Cats like there is on the Polaris and Ski-doos (according to DTR), although I agree about the ring seal issue. The same crossfire came back to test reeds (I am assuming with some miles on it as they stated it was being used in some racing) and it made 157.1. The Amsnow shootout numbers of all brand new sleds put the Polaris at 147.1 "in break in mode" and the F8 at 154.5 both on ethanol fuel. These numbers seem pretty realistic to what I have personally experienced on the snow throughout the winter...8-10 hp difference I would guess is pretty accurate. When the snow gets very deep on the hill, the lightweight and chassis/clutching etc. makes the hp difference very unnoticable and gives the advantage to the Pro in my opionion. The M8 just seems to drag and trench a little more than the Pro when the snow gets deep. It will be interesting to see how the new Proclimb chassis works in the deep stuff without the DD, and the weight being similar to the current M8s (from what I have heard so far). I really liked the M chassis and was close to buying one when I bought my Pro...hope the new one works well but I can't get used to the look yet but the original XPs were weird looking too so it might grow on me.

Again, if you want big HP the pro, etec or M8 don't make much sense. M1000, or the new 1100 four stroker make more HP stock, or anything modded with a big bore, hairdryer or S/C make WAY more HP.

All I'll say is.....So far this year, when switching sleds with Doo and Cat guys....they like my pro more than I like their sleds. I can't wait to get mine back and they can't keep mine long enough. Crunch the numbers anyway you want, but that's how it's gone from my personal experience. YMMV

 

[IDAHO HOT SHOT]

So AC is not letting the cat out of the bag on the 2012 weight sleds. The only thing they say is the 2012 M8 is the same as the 2011....that puts the 2012 M8 at 468lbs dry. I may be a bit cynical on AC not showing weights for there 2012 sleds but I compare it to online dating....Theres a reason why the pretty girl in the add doesnt give her weight

I also found this spec sheet http://www.arcticcat.se/source.php/1346845/arcticcat_snoskoter_2012.pdf

That gives the weights on the 2012 AC sleds in KGs....granted this isnt for the US, but the numbers they give when you converter KGs into LBs align with what AC claims the weights to be for 2012 on the M8. I like the look and what AC is doing with there new sleds....I think they will sell pretty well.

2011 M8 153 163hp 468lbs 2.87lb/hp
2012 M8 153 163hp 468lbs 2.87lb/hp $12,400
2012 11T153 177hp 548lbs 3.36lb/hp $14,200
2012 RMK163 152hp 438lbs 2.88lb/hp $11,999

On that note, here is another way of looking at things

2012 M8 153 $ per HP $76.07
2012 M11T153 $ per HP $80.23
2012 XP 154 X $ per HP $73.00
2012 Pro 155 $ per HP $77.63

Pro fun factor = PRICELESS

According to specs, the Pro 155 is 431 lbs which is 2.83lbs/ hp

You math here doesn't quite follow physics. A Turbo sled will still lose power at altitude as it is x-psi boost over relative barometric pressure.
Turbos sleds compensate for this by turning up the boost to compensate for loss of relative barometric pressure.
Very few riders understand or have the abilities to tune and adjust for this so you will still lose HP at altitude. Even with a boosted sled but nice try at stirring the pot.

What if you have an altitude compensator that turns up your boost as you climb?

i heard the new cats do that.

you're right there's a magic button on the dash by the gauges that makes the air at 10,000ft the same density it is at sea level

 

[BadAftertaste]

I would think that the M1100t is looking for a target Manifold Absolute Pressure number regardless of altitude, and will spin the snail accordingly. Granted, the cat may only see the 177 number for a brief second before charge temps ruin it all, but I bet it can still hit that number at any altitude.

Mark Twain said it best....

[polarisguy1982]

Does a Turbo lose power with altitude? Yes!

POWER LOSS FOR A TURBO ENGINE AT 23PSI BOOST = 6% at 5280 ft

PLEASE NOTE: Since we aren't running full boost 23 PSI at all times you're going to vary between losing 16% - 6% in power due to our elevation.

(Basically as you increase boost pressure, your power loss decreases incrementally...)

The power loss due to altitude is much less with the Turbo. Turbo considerations: As altitude is increased the turbo fan must increase rpm to maintain a constant boost pressure. With large displacement engines (read 1000cc 4-strokes) the turbo fan may have to spin faster than is efficient. The result is slower acceleration. The cure is a larger turbo or lower elevation. Also remember overheated air entering the cylinders has the same effect on engine power as an increase in altitude. In computing horsepower output, engineers will deduct as much as 1 percent for each 10°F rise in the intake air temperature above a “normal” temperature of 70°F.

Being a bit of a hobbyist statistician myself, I would like to add another variable to this discussion....that is; ugliness factor.

I will go further. Who the dark would want to ride such an ugly pos? And no, I'm not joking.

And I'm not a brand guy either.

I think the Pro is ugly but you are a a bit hard on them aren't you? That Cat looks pretty good though, almost as good as a Doo!

You forgot something, the Cat Turbo compensates for altitude automatically......... Still 177 HP at 10,000 feet

Not trying to start anything here but i remember reading something in an issue of snowest last year Real world sled weights So unless snowest was paid to falsify there results thus meaning your Polaris sleds are light and the lightest on the market but they just aren't as light as you guys think. All sleds are 2011's

"Which sled is the lightest?
The Polaris Assault, thanks to a 40-pound diet from its 2010 version. Here are the wet weights (full of fuel and oil, carrying a spare belt and OEM-supplied tool kit):
Polaris Assault 800: 548 lbs.
Arctic Cat HCR 800: 556 lbs.
Ski-Doo Freeride 800: 577 lbs." (Quote from snowest mag)

And im not trying to take anything away from the Pro chassis cause i have friends that really like them and im told they are a phenomenal machine!

the assaults are 15 pds(if I remember the number right) heavier then the rmk's...so subtract another 15 off there, earlier this season there were several threads with pics showing brand new pro's on scales and they were right on polaris's claimed weights.....

Others said this but it should be noted that turbo sleds still lose power at elevation.

Maybe we can come up with a formula on how much harder your heart has to work on throwing that 550 lbs around at 10k feet. That must count for something right? LOL
