Rear shock reservoir pressure

So does anybody know how much is in the reservoir bottle (pressure wise) seen 120/140/160 mentioned on here. I want to re-do mine today.

As it's such a small volume, I would think a 20-40psi difference will have quite an effect on the shock settings?

help please

when i was rebuilding the bilsteins in my rally car I was told you need just enough pressure to stop the oil aerating, the more pressure you use the more it increases the seal pressure and hence the stiction. The seal presses on the piston rod and makes it harder to move. the same would apply here, I think 140-160 is about right but i'm sure the reservoir pressure is in the workshop manual anyway. You can use argon too, which you may have lying around if you weld. you just need an inert gas basically

i was told 140psi ages ago for the compression damping,ive got a nitrogen rig free to use if your ever around kemble in gloucestershire

Thanks for the replies, I have done it now though.
