How does polaris do it?

[tantrumpipeline]

Okay I get they are light, but what makes the pro rmk work so well or even what is the majority reason other than weight they work so well? My buddies 155 is impressive all around and on the dyno is showed a whopping 134hp yesterday, the guy running the dyno said both the 800 etec and 800HO are neck and neck on avg 155-165, any ideas as to what's the majority reason? I know neither of my cats will out pull it and neither my buddies freeride 154 or 163 etec with clutching will keep up either, the 63 did outclimb it on a hill climb in allen creep but the other pro 163 in our group got higher than him. Not like it really matters I'm gonna replace the freak one day and be that guy saying my m is still the best but I like learning the dynamics is all

It is weird, how do they go so well and are 20 hp short??? I think that there clutching is just that good.

 

[maxwell]

with similar riders 30-50 lbs makes a big difference. ive never seen a pro rmk outclimb a xp chassis skidoo but hey thats just my experience. i think the lighter weight balances out its lack of HP but it does not accel past the other brands that is forsure. i also notice it sounds like you werent using the same rider. in my experience no hill is the same and no one hits the hill the same. correct throttle control over the first bump before the hill climb can make a 50ft difference in marks easy. my findings are exact opposite of yours and not just because im on team doo. one of my riding buddies had a new etec 163 and his dad had a pro 163. they both are similar weights and he would just embarass that pro rmk all day long. ( they are probly reading this) lol. i think the highmark competition has way to many variables to determine which sled is better. unless you develop a hill that has a perfectly straight run with no interuptions and the sleds are controlled by robots your never going to get accurate results.

also have you been drinking this fine evening?

eek really? clutching is a personal preference item. they all make similar track speeds moving up the hill so clutching is not a factor if they are all maintaining rated rpms during the climb.

It is because they are the terrain dominator haha lmao

no drinking for this guy tonight, I was just surprised with the dyno numbers and the crap the tech spewed about it all, all the pulls were by the same friend who sold his modded(ported/piped/av gas) xp 154 pre season, but like you mentioned with throttle control, and I never thought maybe someone wants his new toy to look better than his old/his buddies iron too, stupid xp's and their climbing, irritates me everytime, that 154 freeride took me 50+ft higher than my 62 but I still like my old school junk

maybe cause polaris is the way out... oh ya and they're the most flickable ever hahaha, I feel gay for writing that even sarcastically

where did you do the dyno work at?

any way you can get the sheets?

i had always heard the rmk made less hp but havent seen an hp sheet yet.

I can and won't be posting or getting into it, but the owner just joined up the other day so he will be posting base dyno run with sheets, the mods listing and install/work done, the location all the work is being done and the final outcome dyno run with sheets for you guys, so I can't go stealing his thunder, hoping monday or tuesday to have it back we have a bunch of cosmetic work to do before the 21st(first ride in vake weather pending) and a belt drive and a couple other little things, the shop doing the work is pushing him to display so if he won't I will go grab them and put them up

The latest one I've seen from polaris was " the lightest, the strongest, most flickable. Introducing the new 2013 polaris rmk" haha

Thanx for stealing my words Max......

Wow for 20 less Hp they sure go imagine if they had a 160 Hp

I've always questioned why Cat and Poo use centrifugal force to throw the weights out and squeeze the belt, Doo is the opposite. They both maintain the rpms during the climb but one system may be more efficient, like with the greater hp of the Doo, it should be no contest. Years ago lots of the old Doo turbo guys used to convert to Poo clutches, squeezed harder, less heat buildup, maximized the hp right to the top of the sheaves,..... They said. I think if you did nothing else to a New Doo except put on Poo clutches set up properly, admittedly tuff to convert, it would probably be the mod that would give you the greatest improvement over stock. Like it or not, the Poo clutches just transfer power to the snow way better. Drag racing or short bursts on hard pack crap, the Doo clutch is fine.
Tantrums question is valid, and maxwell may be right, the Doo will usually win the climb, but c'mon, 20 hp more and we r on here talking about how it sometimes wins or wins by a few feet. Sheesh, should be pretty clear, but it Obviously isn't.

in my experience no hill is the same and no one hits the hill the same. correct throttle control over the first bump before the hill climb can make a 50ft difference in marks easy.

This is an excellent point. The ability to soak that first bump and maintain track speed/rpm/momentum will make or break any sleds performance on a climb

Agreed, but that's sorta my point, one system recovers or backshifts and up shifts back to optimum better than the other. It's not like one guys always hitting the hill on big whoops and the other one on a flat curve. Tough to think that the Doo always hits a bump at the bottom and the Cat and Poo don't have to ever back shift on the start out.

Not to hate on the pros but in stock form I have yet to see one impress me, maybe it's just the riders I have seen weren't the best , but even on the hills where it took no skill they were Definately lacking. IMO

Same story, didnt know the guys on the pros but seen gofast89's stock 2007 rev outclimbing them, thought to myself polaris is getting closer though. lol

Like the other fourty threads on this site all of us Pro riders understand that we are down in power and lacking a lot compared to other brands ,but im sure 99% of the people on here can say they have seen a pro do a good climb or a technical line stock or not but just wont say it on here .IMO

Well I must be the 1%.

I know this video is old, but it still compares the Pro and the Etec. They climb a descent hill with the same rider on the sleds. There's no bumps or variables other than keeping it pinned.


Just thought it was a good comparison. But if the terrian starts to get harder like maxwell said, than its all rider ability to get the machine up to speed and maintaining it up the hill.

Drinking some Rum and coke maxwell?
