Viper Ltx Se clutch help/opinions

I think with the weight in the tips it will still give you very good belt grab. 2 grams of weight in the tip has a lot more force than 2 grams in the heel if that makes sense. Early on this year when I was clutching my turbo I started out along this same route, had weight in the heels to keep it off the rev limiter and I wanted to load the engine more to build boost quicker, all it did was shift to quick and just drop rpm. I pulled all weight out of the heels and just adjust the tips and it ran completely different.

The steep helix will cause this as well as it upshifts to fast. I think we are all running different helix's. I'm running a 46/40

Mines 51/43, just getting suited up to go test will report back!

Mine is 50/46, which is also why I could only really adjust the tips but that's all I needed to do, I've really grown to love the steeper helix and lighter weights as it accelerates awesome but also back shifts very quickly so you always have power. Mine with the turbo has all the instant snap at any speed as a stocker would, just pulls way harder!

I have tried a 53/41, 49/43, 43 and 45. Just like Dalton industries in my garage. hahaha

Okay just got back in... Clutches are cool, no belt slippage so that's good!

To much weight in tip I believe though, would pull 8800 roughly on roll on and then drop to 8300-8400 the lug it's way back up, would not increase Rpms as fast as before though... Thinking of removing 2 maybe even 3 washers from tips... Good idea?

Ok just to get everything straight, opo primary spring, pink secondary spring, and 51/43 helix? I'm assuming that's a yammi apex helix?

 

[skidooslayer687]

Yep that's correct other then it's a dalton helix

 

[Studroes144]

What's the secondary spring wrap? Sounds to me that is opening up too quick with that steep angle. I'd maybe try going 6-2 on the secondary with the same weight settings

 

[skidooslayer687]

Secondary set at 6-1

 

[newtron]

Do you have any other helix's to try?

 

[newtron]

Try it at 6-2 and c what happens

 

[Studroes144]

A different helix may be better, if u got time for another test just try 6-2 on the secondary with the weights how they are. This shouldn't have any negative affects on speed and should keep rpm up better. Steeper helix will generally need a bit tighter wrap

Secondary set at 6-1

I have the same set up as you do, Hindle power up kit, air box mod, pcv, all from Hurricane. To-day was the first day it ran well. I am using the clutch on the cheap set-up, 8fp weights with 3.5 in the tip only, gwg spring with 3 spacers at 1mm each, pink spring in the secondary at 6-1 wrap. It never worked that well until to-day, when I installed a 46-40 Dalton helix, with three washers, then it came to life. It pulls hard all the way to a top speed of 100mph. This speed was on a hard packed trail, not ice. My sled is a DX LTX with 650miles on it. Hope this helps and by the way I also have a Ulmer's clutch kit. Sorry I forgot I run machined clutches with a 8dn belt.

Just went out for another test... So now I'm 8 washers in heel and 6 washers in the tip, I pulled 2 out and went out and tested before I saw the secondary post... I don't know what to think with this one, pulled 8800-8900 from a roll on, then back down to 8300, then back up to to 8700 fairly quickly, highest rpm I saw with this was 8900 on top.... Rev limiter was a bit more present this time to... This is getting a tad bit frustrating, the best set up so far was the 4 in the tip, a tungsten and 4 washers in the heel... Even that has that dip in rpm but seems the least bit affected
