Ulmer kit

[DMCTurbo]

You'll want 2 washers in the heel and 2 tungstens in the tip. That should put you pretty close.

Are you running a similar setup? What is the target rpms for TD powertrail? I know the pink spring Allen uses is a very light spring but I do like the low smooth engagement. But depending on time I'm gonna try the black/blue dalton spring and see if there's any performance to be gained. I'm guessing the dalton spring will want a little more weight in the heel but I'm no guru when it comes to clutching. Thanks for the help. Anyone else try a Dalton spring with STM weights?

Loading the STMS will depend alot on Tune, and if you are gonna run the bigger sec spring and/or reverse helix.

If you run something like the race flash which have lots of PSI around 5500rpm, you will want to load the HEEL with tungsten more then likely. Since it will over rev with that much boost down low. I am not even close to testing yet but I will start there.

I also have the TP sec spring and reverse angle helix I will test with, If I run the race flash I may need to go with a progressive helix instead. Not gonna be same as Ulmers loading Im guessing as his flash testing is not early spool.

Gonna be a ton more clutch talk(at least from me) once I get to dive into my STM 60YS. If I start clutching before I throw a tune at her, then it will be alot diff, but would make for good info.

Dan I was thinking of starting a post where we can guess how many miles you put on your sled before you cave in and install your tune. I'm guessing it wont be too many.

That is funny....lol

But with this turbo, I dont have that 'need' I usually have with other sleds to power up ASAP. Its got all the legs needed really for now. Also it helps that I dont ride with other winders, as that then becomes a grudge match. LOL

I really think a stocker with good clutching will be a ton of fun in itself.

Im still waiting to see more info on the "stock gauge" map selection, with momentary button. I have the iPhone setup all ready here but the stock gauge splash screen selection will be what I want to run more permanently.

I'm running the same tune so you should be pretty close.

I'm running the TD powertrail which in the description says it's stock driveability to 7k rpms then the added boost comes into play. I'm gonna start with just adding some weight to the tip for now. What is the target rpms for TD powertrail? I know some other flashes they are up over 9k rpms. Thanks it's dam cold here in Maine -30 without the wind chill so until things warm some I won't be making adjustments on the local drag strip. Anyone riding in Maine especially northern Maine be safe and ride with a buddy. You can die quickly out in these temps especially in out on a night ride and something happens. We all love to ride but be smart freezing to death isn't worth it. Ride safe

Im running 60Y stms with the dalton black teal spring and TP glide washers. I still have a little tinkering to do, but works pretty damn well. Stock helix, dalton orange secondary spring 6-1. Tungsten in the heel and tip, plus 3 washers in the heel and 4 washers in the tip. Get about 3400 engagement. Running 270 race tune. I wouldnt mind a little higher engagement, but I like loaded up heel for trail riding. Sled feels really snappy, lifts the skis easily on rollers and little bumps on the trail. Plus I find with the heel weight, if you spin it doesnt blow out the track and overshift as bad. Im probably going to try the 15.6mm primary rollers this week and see how I like it. Should get the engagement up a bit higher, but Im not sure on any negative effects.

8300ish coming out of the hole and pretty much immediately pulls up to 8700-8800 rpms and stays there.

I think you want to be right around 8800 rpms, power starts dropping after that. Also, when you watch the TD youtube videos, seems like those sleds are all turning 8700-8800 rpms.

Powertrail 8900-9000

Powertrail 8900-9000

Says who? Watch the TD videos. And looking at dyno graphs, these engines make the same power from like 8300-8800 then starts falling off.

I believe bens race sidewinder races at like 7900 Rpms, but I could be mistaken on that.

Fair enough. He would know better than me. That's the beauty of these sleds, nice fat powerband.
I think the reasoning is clutch to 8900-9000 rpm in perfect conditions so if it's loose or heavy snow you're still in the sweet spot.

My set up now,is supertips loaded 14 in tip 2 in heel for total 80 grms,with loans orange primary is much higher rate than what my kit came with,spring full shift rate is 145

Hi phil,i have EVO-stage 4 tune and CAI with stm supertips 60y loaded to 80 grms two tungstens in tip center empty and one washer each side on heel,we blow out on engagement even with tpi orange primary spring which is 35/147 rate and stock 35 helix with orange tough guy spring at 60 degrees,now this tune wants 9000 min at full shift,in fact kit states 9150-9400 but mine shifts to 9150 after engagement is around 3000-3200 max,but spikes to the rev limiter to 9600 on hard take offs,do you think if I added another washer to each side on heel,it may help? I also may try a Dalton blue/black 53/133 before I do anything else,what do you think?

TD powertrail makes best power at 8900 rpms

I'm certainly not a clutching expert, but I've always ran lots of heel weight, even with my turbo nytro. Not the best for high speeds, but works good for trail riding and drag racing buddies in snow. You can move the weights pretty much where you want, see what you like best. Just when you load the heel with the supertips it lowers engagement, so you would need a spring with a higher initial rate to keep it at 3200rpms.
