TRS clutching NA

[nosman4]

I am the buddy that dktraw rode with yesterday. I was pulling 8150-8200 with the 61g speedwerx setup yesterday and about 31-32mph track speed in awesome waist deep pow. The sled felt kinda slow and was just too quick to blow the track out and then would stop pulling. I took Tonys recommendation and added the extra weight which brought me up to 62.9-63g on the flyweights. I rode again today, but halfway across the state and the snow was completely different. To be honest the snow sucked..... The response on the trail was better and had a lot more power to be felt. Pulled about the same R's when climbing, but snow was not comparable. To me though this was a huge improvement, clutch heat was way down (I could rest my hands on the clutches without burns) unlike yesterday. The sled didn't seem to hit a 30mph wall like it did yesterday, just wanted to keep pulling. I need better snow to give an accurate assessment though. I am happy with today and have high hopes, but I am definitely not seeing R's like Tony is, I have never seen 8400 on a pull except down low in elevation.

Good you guys are working on it. I don't get how results from you guys to us can be so vastly different. My buddies and I have tried EVERYTHING. Tony's set up is the only thing that has stayed in.

I have a buddy that would change something every night or even during riding everyday. Since Tony's set up went in... It hasn't came out. His more or less stock sled gives turbo sleds fits. I have rode big bores, stage whatever's ... I would take the simple clutching change over them all. Except boost of coarse. I am a addict.

Good luck!!! I just can't keep going WTF. Something is off... It will show up.

Ian,
What is your setup now.
You may still need more weight. It would be nice to find some tungsten washers.

 

[nosman4]

My current setup is stock sled with pro rmk gears, 40-32 helix, 125-175 secondary spring, 110-290 primary and the Rogers speedwerx weights with 63g, gates belt.

Spaarky-
I have one question for you guys. Did any of your sleds that run so good now. Especially your friends sled that gives turbos fits, did they all run good to start with? Could you get 83-8400 out of the stock setup? No matter what I did with the clutching or the sled it would not pull more than 8100. I have gone over everything and it all checks good. Wondering if the good running sleds are the ones that are having great luck with this clutching?

With bully dog tune reloaded and Carl's clutching back in, my sled ran awesome today. I put in another new secondary spring yesterday, not sure if the new one i put in at the beginning of season was bad or what. But in over the hood snow today she was pulling 83-8350. Sometimes 8400. Ran flawless all day.
Buddies stock sled with Tonys setup had same experience as i did with his stuff. 81-8200 very flat feeling and just felt like it wanted to spin and not go. His clutches were hotter than mine with Carl's setup.
Called Tony and gave him the info and he thinks we are running a to light of weight for 6-8k ft elevation. Stock sled needs to be loaded to 62.8 grams and my stage 3 is going to need closer to 65 grams. We are slipping in the primary and never loading motor. Monday im gonna put his stuff in the wifes stock sled loaded at 62.8 grams and see how that compares to my Carl's clutching.

What is the full Carls set up you are running?

What is the full Carls set up you are running?

Carls clutch kit is a double cut helix with a 62-42 and 60-40. Im running in the 60-40 side. Stock secondary spring and there roller bearing under spring cup. Primary is the old Pro stock spring which is a 140-330, and they use belly buster weights for your elevation. Mine are 66s.

Thanks. Helpful to see what you are comparing.

Ian,
What is your setup now.
You may still need more weight. It would be nice to find some tungsten washers.

If you are an avid fly fisherman put a tungsten bead head behind the bolt. You can get them from .3 of a gram to 1.5 grams. Depending on the bead size and room behind the bolt. Very inexpensive way to add weight.

Update from testing on a stock 16 155 2.6 sled. This is my wifes sled and has always ran great. the only real bolt on it has on it is an SSI stainless can. Prior to changing to Tonys clutching I was running stock Primary stuff with a 56-42 helix and stock secondary spring. Its always ran really close to if not better sometimes than my stage 2 or stage 3 stuff. It has always run 8-8200rpm at 6-8k ft elevation and 37-39 mph track speed. wife couldn't go, so I had to rip her sled up, do a bunch of test runs, then rip down to truck and get my sled with stage 3 setup and carls clutching so I could have a good comparison to what hers was running.
Mondays setup for my wifes sled

Speedwerx L weights with small screw and two washers- 62.8 grams overall
110-290 primary spring
42-32 helix
125-175 secondary spring

First impressions when leaving the truck headed up the trail were awesome. turning 8500 at 4kft and pulling hard. once up at elevation (7kft avg.) the snow was pretty good still, wet and heavy though, still soft though and sinking up to your waist when walking. It was down to pulling 8250 which isn't bad, but only 32mph track speed. the clutches were clean and didn't seem to be slipping the belt, but while working her hard in the trees and climbing, I could smell belt. clutches were WAY to hot to put your hand on. I thought it was doing "OK" for how deep and heavy the snow was.....that is until I went down and got my sled....my sled with carls clutching and 66g weights was pulling 83-8400 and high 40s track speed. stuff I was struggling to climb out on her sled, mine would go packing the skis out the top. clutches were about the same temp, but I couldn't smell belt while riding.
Now I know your gonna say not fair, stage 3 against stock. but again, her stock sled has ALWAYS ran very very close to, if not better most of the time to my stage 2 last yr, and now my stage 3 this yr.
Tony thinks that the L weight is just to light for our elevation and we are slipping in the primary. He is sending me some lightning weights and a different helix to test. I will report back after more testing but Unfortunately I will not be on the snow again until mid next week.

dktraw, what belt are you using?

 

[dktraw]

Im running the poo 183 belt. Ian (nosman4) is running the Gates 45C on his setup.
Ive ordered a couple gates belts to compare to the poo belt

 

[tdorval]

Second or third day with trs clutching using the speedwerx weights with an slp pipe and ssi ti can. Pretty impressive so far. I'm coming off a turbo and this things a blast. As some have said suckers shift and haul the mail on the trail. Pulling 42-45mph track speeds in a climb depending on conditions. Pulling 82-8250 at elevation in the beartooths. Havent even taken the time to feel the clutches honestly. Happy camper.

 

[dktraw]

Tdorval, what elevation? Speedwerx weights empty or loaded in the tip?

 

[tdorval]

Same as trs, 8-10k. Empty weights

 

[dktraw]

your running the weights empty at 61 grams 8-10k ft and running great. so we are thinking that the 61 gram base weight is just to light to squeeze the belt enough once you go down in elevation. we are probably needing like a 63 gram base weight for 6-8k ft.

 

[2XM3]

As of now

diamond s can, spl pipe, pro pulley for gear down

68 gr mtx weights, titanium 130/330 primary spring

helix 56-40 .36 black purple with 2 delrins

8500 at about 6000 feet +/-

seems to work good so far may try lesser initial angle

 

[dktraw]

If any of you guys at higher elevations want a set of these speedwerx weights Ill sell you mine for a good deal! They seem to be working well above 8k ft elevation.

My setup: '16 155 2.6, SLP stage 2, gear down, Speedwerx L weights, 110/290 primary, 125/175 secondary, 40/32 helix
This matches my experience with this clutching too, pulls extremely hard til about 6500 feet, then only 8200 rpms and mid 30s track speed, I have the speedwerx weights loaded with short bolt/one washer now, going to try loading them more (although it seems counterproductive with the rpm loss at higher elevations) and if that doesnt work Im going back to Carls, its more fun, pulls harder and turns track better, I'll live with hot clutches, the trs setup was just as hot if not hotter yesterday than turbo Axys and 850 doo that goes thru a belt every 200 miles

The 125-175 may be to light for all snow conditions. I may have jumped the gun on this spring for all conditions.

With feedback from Sierra Cement type riders, it may be upshifting to quickly and hindering backshift. Testing is in order.
I apologize to those having issues.

Hopefully my “new short block” is in today and I can test. I’ve been riding the mule the last two weeks.
