TRA settups...attn clutch guru's

You need to get the doo race manual. Has all the ramps with pictures and all springs plus lots of other info. At this point I'd wait and get the 09 manual next fall and it may have more XP tuning info in it than the 08.

Good Luck
 
xp 163 800r clutching

well as the season has gone along snow setting up have some clutching issues. gearing 19-49, ramps 433,s, pin weight 22.3grams,earlier roller problems went to after market rollers helped out a bunch. from 6000ft. to 7500ft. cliker 1 7500ft. to 9600ft. cliker 3. not a problem changing to different clickers for me . never had any belt problems ,started with 166 now with 377 have over 1100 miles on sled. never have blown a belt. when hill climbing get to the top on along pull rmp.s are pulling down to about 7600 rpm right at the top of the hill. so my thinking going to try 44-40 helix but having second thoughts about using this helix,so for you clutchig grus is this going to work for me. i see doo does not offer a 44-38 or 44-36 so if any body does have any ideas let me know.
 
I am running a 44-38 from goodwin in my 163 xp at 10,000 ft. The backshift is much better than stock still falls off 200 rpm on a long pull.
163 xp
gearing 21-49
primary pink-purple
15 grams
clicker 2 or 3 for snow conditions
 
I have no issues with eating belts, performance, track speed etc...But there is still one thing about the TRA that I would like to improve upon and want input from anyone that has found a cure (or a way to minimize) the RPM variation in different snow conditions and terrain. I have a 800R 159 that runs VERY good, but they are a peaky engine....run under 8100 and you missing out, over 8400 and you are too high. I find with just about any settup that I have to run 2 clicker setings lower on the flats (or firmer snow) than I do when climbing or in the deep. I am VERY picky on my clutching and always want peak performance so I find myself playing with clickers 2-3 times/ride as I go from road to the play areas.
Has anyone found a good mountain settup that shows consistant RPM in a variety of conditions?
And yes, my TRA`7 is in good shape...it's not the clutch itself, just the classis TRA behavior.....is there a cure besides a P-85 or quick clickers??:beer;

You sound like me. I have to haul a skimmer into our best riding area and that TRA would go crazy with a load like that. To stay sane I'd start in on the medicinal supplies and be tanked by the time we got to the cabin. It was either get rid of the TRA or become a drunk. The TRA was removed for health reasons.

And you better get a bank loan, none of that stuff is cheap.

The only reason I can think of that BRP has not given up on the TRA is the money that the TRA clutch makes for BRP is atrocious. The clutch can be made to run if set for the current temperature, the horsepower at that moment, the weight of the sled and no changes during the run. BRP has convinced the market that it is their fault if they can't find that sweet spot on any particular day. Nice.
 
i have read this thread from the start to now and have to stop and dry my eyes from laughing,
it turned out to be so very simple and no one even mentioned it .oh well it does keep the boys employed .guess on fellas. LOL's

any one else got a widget for sale.

It was simple....once I fixed BRP's "designed in" flaw on the '07. It seems they try to "design" a clutching flaw every year, it was a different flaw for '08 and now '09 is appearing to be yet a different flaw. When will they learn?
 
So, what is the answer brew? I'm don't know much about clutching exept what I've been reading here for the past couple years, and everyone has a different opinion. I still run stock clutching and don't want to fiddle with it all the time, so I wait till there is a proven setup that really works. I don't burn belts after the motor was aligned, so now I want to get more track speed. What is the magical setup that no one can seem to figure out? You sound like you know more than others.
 
Has anyone heard what the setup should be for the 09' 154" w/SLP y-pipe, pipe,& can. Also when you add there head w/domes for alt.8000' up. Checked the website from time to time, nothing updated last I checked.
 
same for 07 , your correct , the 08 is a different issue in the secondery but the issue in the primary is the same as the 07 primary issue.

take a poll and i would bet a yes in the doo makes a new issue every year .
looking at 09 the issue is going to be totally different issue for sure .

all based around belt sales .

compared to the opposition the doo belt sales are way up there .

we stock belts for all brands and the doo belts we sell are 95 percent of our yearly belt sales.

07 issue #1 spring tower cap
#2 secondery bushings were way to small and wear at a rapid rate.
#3 front arm in skid located wrong

08 issues #1 primary spring tower cap
#2 secondery spring wrong for mtn application with the track supplied

09 issues waiting to see how they think the 43/47 will work in the mtn for belt sales

doo has not been steller on secondery spring selection .historically speaking
same guy in charge of this is in charge with the recoil design .

why they seem to think that it will work for a huge selection of there tracks doesnt bewilder me at all . i just accept they see it differently.fine for a tral sled but mtn application they need to rethink there approach.

watch the track speeds .
06 was faster than the 07 and the 07 was faster than the 08 as delivered with every thing set up and in spec .same model

it is a balancing act and they keep neglecting to put the variable of the sec spring into there equation .

but what the ell would i know .
 
Search "Turboal".....he has said several times on here what is needed for the 08 XP's.

The 08 needs much more than a stiffer secondary spring. Here is a hint...Take the stock primary spring, ramps, and pins and start from scratch. The primary setup is probally the worst I have ever seen on a stock sled. Stiffer secondary spring is a good edition also.
 
pretty hard to argue with the results we had from haveing a good cap and a different sec spring . highest track speeds we have ever achieved from the doo product , considerably .
with each done we have eliminated all the massive slip going on in the primary and the sec and is indicated by the major increase in track speed at elevation and in the deep stuff, but thats our snow and our air .
what is laughable is how close they were .

change the spring and ramps , it does eat them as fast as the stock stuff when the tower cap does what it is doing .
they finally put in the sled the primary spring we have been useing since 1996
ramp and roller destruction was due to the cap factor and it ate ever thing we put in these primaries since 07, never before that had we seen wear on that level unless a guy had 5000klms on a sled , not just one or two rides like we saw a lot of sleds show up here and have during the last two seasons.
so much has been tried and good for ya if ya have something that works .
just what we found in our wee small market area

AL, nuttin like a stiffer finish spring in the secondary, at the end of the day it's all about how well you sqweeze the belt. Same unchanged TRA issue that's been happening for years in deep snow and high altitudes.....By the way folks the 09 multi-angle helix is a huge leap for skidoo summit sleds. It's taken BRP engineering years to come off the straight 44 or 42 helix. LOL

Some guys might want to try Teams Black/Lime it's either a 160/300 or a 180/300 i can't remember.

OT
