Pro vs E-tec

[maxwell]

Makes me chuckle when people say the Poo is underpowered. Let's put it in perspective. All 800 2 strokers put out excellent power (Poo is lowest at 154 with Etec and Cat at about 163 hp) Difference of 9 hp . Works out to about 6% more. Poo has the better drive train we all know and lighter sleds. So when you do the HP to the ground calculation there is not much difference. It takes significant amounts of HP to make a small difference in performance on snow. Underpowered, hello.

who are you to say the pro has a more efficient drivetrain?

well call that one a wash.

lighter? reading to many magazines and flyers lately i see..

also a wash.

crappy track and a bit less power puts the pro lower on the hill PERIOD.

BUT it is still a great machine.been pretty much problem free and handles well. oh and the price is right.

I would tend to agree with maxwell on the fact that the weight and horsepower are a wash. Edge in horsepower to the e-tec edge in weight to the Pro. As for drivetrain efficiency i would take polaris' set up over doo's anyday. Brp clutches have never been their strong point. Still ging to be interesting this year. Cant argue the price of the Pro though.

Oh wow Maxwell easy now lol, we all know that the Polaris clutches have been far superior at putting power to the ground for oh 25 years now and that is a fact period. You may be too young to remember when the 488 fugi would lay a beating on the 583 Rotax ALL DAY LONG and we also all know that the 583 had WAY more horsepower it was ALL in the clutches my friend. I am sure doo has improved but there is a reason people still put Polaris clutches on their Rotax. The REAL bottom line is if all I cared about was who could climb the highest I would have a turbo on my sled but the fact is out of the box on both sleds and I mean NOTHING touched I seriously doubt that you could tell much difference between the two with good riders on both. And don't forget that Doo has done major work on that chassis in the last few years to make it handle more like a....... I have to say it, Polaris

 

[mach123]

The only reason that I was told growing up why people would use poo clutches was because they were cheap to fix and cheap to have a box full of parts, as we all know doo is not so cheap to play with trial and error. HMMMMMMMMMMMM

 

[maxwell]

polaris clutches being more efficient is pure myth. they both hold the rated rpm, make the same trackspeeds and both pull just as hard. sure doo took a bit longer to figure that one out. but wait the tra clutch has a magical feature that you twist with a wrench to adjusy rpms based on snow conditions and temperature rather than rifiling through a box of clutch weights before you go riding. no sled has blown past me in stock form because it has an ancient p-85 on it.

1991 called they said they want their clutch back?

man im bored

No it's because doo clutches used to fly apart and take out the belly pan This is not a joke by the way. I am sure they are better now but they had the worst clutches, ask anyone that used to ride an older one, if you went on a 100 mile trip you had to carry at least 3 spare belts. Young guys that jumped on the doo when the Rev came out missed all the fun stuff lol. Polaris clutches were by far the best on the market for a very very long time. I am sure that everyone has a good setup now but it was not always this way.

You never fail to make me laugh When you riding again? I so wish I was riding now instead of looking at my computer Maybe next weekend.

 

[enis750]

Just buy a doo anyway.

Sent from my Nexus S

thx for sharing your pearls of wisdom.......


IMO..both sleds r great
some have points that exceed the other
at the end of the day..... how much u wanna spend and what color of gitch you gonna wear

lol actually im posting from my tablet on the way to valemount!!

Nice, be safe.

 

[MATTIAC]

I've never riden a pro but timber_tramp had one and he admits the seat of pants the etec pulls much harder. 6% or not it's noticeable. As far as riding in the trees he prefers the pro

 

[tukernater]

As for clutches NOTHING yanks like a set up TRA drag racing,In the hills a TRA set up properly will run cool and last for ever.I'm one of the guys that cut a p-85 clutch to fit my doo only because there simple,but i learnt how to set up a TRA and it a great clutch.the chassis are both great the poo seems to be better in the trees?i don't know don't ride the trees.like both but doo dealers closer by about 1km. lol

Again the good old BRP union boys have spoken. Make sure you all listen to them because they know ch!t. I remember maxwell saying that he never goes into a brand fourm and bashes a product. Must be getting old as he can't remember ch!t. As for Brp clutch really a nice setup because of the adjust on the fly. But if you put a set of Dalton adjustable wieghts in a polaris or cat you can have just as much adjustability and ease of it.
BRP clutches are heat hounds, they blow belts and are hard on clutch parts because of the design. Oh and also hard on crank bearings because of this. The design is closed not open like a Polaris or Cat,so hot air has a hard time exiting the clutch so it transfers into the belt and crank more so than a polaris clutch. Also the BRP clutch is HEAVY comparong it to the other brands. as a result all that wieght WAY out on crank stub puts extra stress on the Bearings as well.

Hope this helps.

Gotta agree, doo clutches are junk for mountain sleds compared to other ones out there. Talk to any shops and they will tell you the same. In fact the sled shed guys from Revy posted this somewhere on the forum. Doo clutches are great for the 1/4 mile though dragging though!


There's a plus and minus to both sleds. Plus to etec is power, minus is the clutch. Plus to Pro is handling, minus is the power (it may feel way more underpowered, but is very close to the etec on the hill).

Worth noting is 2011 etec's have a recall on the pistons for rebuild... just something to keep in mind.

 

[trench]

When Snowest magazine came out with their test of the mountain sleds they measured the clutch temps after a few runs. The Doo clutches were way hotter than the Polaris and Cat clutches, if your making heat your wasting power. Checked buddies Doo primary at the end of the 08 season, after 500 miles it needed a full rebuild!!! Hopefully they have improved them since that first year of the XP. Yah Maxwell it's just a dumb magazine, WTF do they know?

 

[Warhawk]

LOL Trench. Yah Maxwell it's just a dumb magazine, WTF do they know?

One thing your going to see also from the BRP products is they are going to wash out on a steep side hill. It has to do with a Ski stance that is as wide as my 1974 RolloFlex that i use to own. Body panels are wider than the ski stance by a fair amount so when you lay the waterbuffalo into a steep hill you lose bite from the ski. If you look at the Polaris and Cat designs you will notice the skis are out and body panels are way in. This allows the machine to be leaned into the hill better.

I read it on this fourm and it was posted from one of the BRP union boys that BRP is/WAS the best out of the box. LOL the box was built in 1974. They must have a hard time giving up on the performance of the Elan.
Thank god i got rid of the 2010 waterbuffalo. Going to love this year.:d
