x500 restriction

[iolite]

i have removed the washer in the variator and fitted it to the outside so that the length stays the same and that i dont cause damage to the shaft as i torque the bolt. i have noticed that my revs are def. down and I have a better top end speed. I am shure it will improve my fuel consumption! busy checking that and will let u guys know.

Excellent, Iolite!  Thanks for experimenting for all of us!  I'm very interested how it will go. 

You are keeping in mind that this MAY be hard on your belt, right?  Well, time and further inspection will tell.

keep us posted - please

I can't see that removing the washer would change the low to mid performance if you are using the same weight rollers and clutch springs, but it will increase your top speed if using a longer belt. Or am I missing something?

[wordslinger]

..i've learned, it's all trial and error....


 

[sidthesloth]

But wouldn't the low range still be the same? I ask to learn.

 All should remain the same except the top. You should be able to climb a bit higher on the veriater to get a taller gear.

..i dunno...if there is a bushing..washer..and you remove it...the drive ratio will then change...

[Hoolander2]

I think it would HAVE to change from idle on up.  At idle the belt is now riding higher in the variator pulley and lower in the clutch pulley and gets higher as you rev.

[wordslinger]

..i agree hoolander...it'll change throughout...

[Hoolander2]

Ok, so it's possible then that you may be almost spinning the clutch fast enough at idle now to almost cause it to engage.  Sound logical?  May need slightly stiffer springs?  As well as maybe a longer belt? 

You know it's pretty cool we've got two guys in different parts of the country doing performance mods on 500s at the same time and both posting results here on this fantastic forum ! ! !

..i know..environment makes a BIG difference in the results of any mods...

At idle the variator is open, the belt is at the bottom, the washer only limits how close the drive faces are at the top of the range, full speed, 2,500rpm is still the same, eg. 1/3 the way up the drive face, @ that position the ratio should still be the same?

I'm with sidthesloth & co.
Usually the washer limits only the minimal distance.
It may be build different with an overall effect, but then its removal should be dramatically esp. at the start.
Xcitings idling can be at 2000rpm (cold start) and clutch engages at 2500rpm (at crankshaft with standard transmission ratio).

I think it would HAVE to change from idle on up.  At idle the belt is now riding higher in the variator pulley and lower in the clutch pulley and gets higher as you rev.

But the washer only comes into play at full closing of the variator? When the belt is, say half way up th drive face, the ratio would be the same regardless of wether there is a washer there or not?
