Dalton Black/Orange secondary spring

[XP123]

At 6-1 I had 2 washers in heel and 2 washers in the mid along with the 2 tungstens in the tip. In the conditions today it was pulling 8900-9000. When I went to 3-3 I removed the 2 washers in the mid and she pulled 8900-9000. It was 2 mph faster in 2000'.

Why didn't you leave the weights the same when you went to 3-3 this way you would know what effect the change in spring position would make. Changing the weights while changing the spring position at the same time won't give you a good comparison.

I beg to differ. I knew by going to 3-3 I would lose rpm. It's not a good comparison if your not pulling your target rpm. That's why I removed 2 grams and I could compare both twists while being in my target rpm range.

Do you know for sure you would lose top rpm?

Rule of thumb and I obviously did seeing my rpms were in my target range after removing weight.

It may only change your shift Rpm and effect your up shift and down shift. When I went from the TP orange to the Dalton black orange my sled up shifted quicker and down shifted slower but my top end rpm stayed the same. The TP orange was much harder to install because it felt much stiffer.

Ok thanks. I have the 60y weights. Here is one compared to the stock curvature.View attachment 137659

Same weights as I am running. Still testing and tuning, they seem pretty good, adding a 39/35 helix tomorrow and Dalton black blue primary spring. I am running the hurricane 270race tune, would be interested in testing out a set of Dalton weights.

2 tungstens in the tip and 2 washers in the heel.

Yup,what I started with from allens stats,80 grams total set up that way,and is where I will go to next again.

For you guys that installed the dalton black orange spring how did it fit in the pocket of the helix? Was installing my new 39/35 helix tonight and I noticed the spring coil doesn’t really sit in the pocket of the helix like the stock or orange thunder products spring does.

It’s like the spring coil is to large and it kind of sits on the outside of the spring pocket on the helix. I will attach a pic but it’s kind of hard to see.

That’s because the TP orange secondary was wrapped two tight it was extremely inefficient, testing has proven that increased wrap from 50 degrees can actually cause lowered rpms from belt sticking in the sheaves. Read Steve’s post on clutch temps, you can run the TP orange @ 30 degrees without slipping. So running 60 degrees wrap is way too high.

I didn’t notice any issues with the fit or tangs.

I'm going to try my Dalton B/O today @ 3-3 just to see how it performs compared to 6-1. I liked the way it performed at 6-1 but if it still performs well at 3-3 with less heat then that's what I would prefer. I'm betting with a harder belt like the 8DN 6-1 would be preferred but with these softer belts a little less pressure may be better.

That’s interesting. It’s like the diameter of the coil is to big. The tang fits in perfect and then when it wraps around it starts in the pocket but then comes out and sits like on the top. Maybe when it’s wrapped it will twist the coil enough that it will sit in the pocket? The other springs I have are smaller diameter coil and fit in the helix pocket with no twist on them.

I just checked mine out today with the stock 35 helix and the spring fits perfect. Maybe it's your helix?

OK I just got back from testing my sled with the Dalton B/O secondary spring. My sled is stock tune with the TP big venom primary clutch kit. I have the stock 35 helix and tried the Dalton spring both @ 3-3 and then 6-1.

First I tried 3-3 and when I installed it I wasn't very optimistic because there was very little pressure when I twisted it. The reason being and I'm sure most know is the Dalton need more twist because of the location of the spring tangs. Well I decided to give it a try. I hit some fresh powder and it only took a second for the sled to fall on it's face and squeal the belt. I tried this for some time but it would continue to do it. If I stayed out of the powder it would run but lacked the snap I'm used to. I kind of expected this to happen.

Next I went to 6-1 and while installing it I felt more confident it would work better because it had some decent pressure. I then went out and hit the deep powder again and no matter what I did I could not duplicate the sudden stop and belt squeal. The snappy feeling was back and the sled ran great in and out of the powder.

I would not recommend going 3-3 with the Dalton spring unless you can test it first with the ability to change it back to 6-1. In other words don't set it to 3-3 and then head out on a 10 day backpack trip because I don't think you will like it.

So I ran the sled pretty hard through some loose powder for some time and then checked my clutch and belt temps using my super accurate five fingers and palm. My clutches were COOL to the touch. In comparison when I had the TP orang with 33/35 Dalton helix my clutches were HOT and so was my belt. This is the reason I decided to try the Dalton spring and go back to the stock 35. For now I got what I was looking for, a great performing set up along with cool clutches. I now know for a fact that HOT clutches and belt are not the norm with these sleds and they can be corrected.

Anyone try 6-2 yet?
