Light Weight Clutch

[friscospices.com]

I know I have seen the light weight clutch cover but how about a complete kit for the clutch? Spun weight it a huge factor in not only enginee throttle response but also centerfical forces. Im not sure how you would calculate it but I was thinking of holding a bicycle tire and spinning it how hard it is to move side to side compaired to moving it side to side when not spun. So here are my thoughts

Clutch cover
Titanium clutch cover bolts
titanium rollers
titanium pins
titanium spring
titanium clutch bolt

Can these be possible?
How much weight would we save ?
How much spun weight would be saved?

Am i missing anything else that could be Titanium or carbon fiber?
Oh and can it be reasonably priced (under 1,000)
Would it be worth the coin?

Been done for a year now, tested on high HP sleds, and used in the X Games Hill cross. 2lbs lighter on primary and I think 2lbs lighter on secondary, also can shave to whatever belts you're using, like the a lot of guys using Artic Cat belts on turbos. I think its around $1200 for cover and taken weight out.

First ran lightweight, machined TRA3s from the race shop in Valcourt 15 years ago - works of art, and the throttle response improvement was very real. As durable as any forged TRA3 over the counter. Cost to racers was about $500 back then. They f'ing worked. Same concept still applies.

Carbon Cover is 650 with Ti bolts but the rest of the items is what I am speaking of. who makes them. If nobody does then I think I may get them machined and try this. I dont think the secondary is a viable candidate because of cost of the machined components you could change. How much torque does the clutch bolt have on it? would TI be strong enough. I assume it would with the campher taking most of the stress

Alternative Impact has all the primary bolts available in TI but the weight pins which are available from Patrickcustomcarbon.

I would like to see someone develop a CVT that replaces both clutches and the gear reducing element in a light weight package (preferably inside the driveshaft /drivers). I had a system drawn up twenty years ago but the control function was cost prohibitive (more than $10,000 each at the time). But would easily remove 10-15 pounds of rotating crap and 5-10 pounds of non-rotating weight (depending on chaincase or belt drive).

Let's look at reality. Polaris p85 clutch has been around forever. It holds together and it's simple. If you really think that spending $1,000 is gonna get you anything more than bragging about carbon fibre parts then maybe your money can be spent elsewhere. Can you really tell if it revs faster. Does it make more hp? Then fill your boots.

Does it rev faster with no clutch? It makes the motor sound like an impact wrench, so yes I believe that removing weight from the primary will make the sled more responsive, how much? I dont know thats why I'm throwing it out there. I am sure some math/engeneering guy on here could chime in with some actual legit info. I certainly dont want to spend a grand without some actual well calculated data. Whats "Fill your boots" even mean?

I have the light weight clutch cover and titanium pieces from pcc, 1.25lbs lighter. It revs faster, you can tell.

I'm going to buy this for my new axys when it's in. Made by zollinger racing (not zbroz). Still have to out source the rollers and pin parts. But they just pulled from their website due to a recall.

It does rev faster having a CF cover and titanium bolts. It's very noticable

Is taking weight out of the clutch a good thing for the crank/motor? Changing the weight on the end of the crank is going to affect harmonics dramatically I would think. Is that good or bad? I guess if it moves the harmonic resonance to say 9000rpm then it's good because you never ride there. If it moves it to say 8000rpm, not so good.

Good thought. I wonder who would know something like that. I love the zbroz cover I bet with those spokes it may move some air as well. Does anyone make a titanium clutch bolt? How about the rollers and their pins as well?

 

[boondocker97]

Alternative Impact makes the clutch bolts. Don't think I've ever seen any pins or rollers. I would question if you could het the Ti hard enough to have acceptable wear for pins and rollers.

 

[BILTIT]

patricks custom carbon makes the clutch bolt and pins.

 

[BILTIT]

Patrick would be a good source of info for lightweight clutch effects on the engine. He has been lightening clutches for race teams, if I recall correctly, for many years.

PCC makes all of the parts you have mentioned except rollers and spring.

Titanium spring

And Renton coil spring for the primary spring, and team for the secondary spring.

Also Patrick custom carbon is taking extra material off the secondary clutch and I think the primary also but I'm not 100% on the primary.

Never heard of titanium rollers.

 

[BILTIT]

Yup he takes extra off the primary.

This is made by Zollinger Racing, not zbroz, which is a completely different company
