I have the same set up & was interested to see the suggested IP for the drive gas at 130PSI - what fill pressure do you get with this setting? I started out with mine at 140PSI, but found it stalled below my target fill pressure of 200 bar & I now have it set to 150PSI IP & have no problems.

Although the mechanical advantage of the booster is 25:1, practically it is less than that - maybe closer to 20:1 & therefore needing a higher IP on the drive side. Anyone else have this experience?

Great article though & thanks for sharing it.

Same exact issue here. I found the IP of the reg is the real factor in how high of PSI you can boost to when using drive gas. 150 psi is what mine is at now.
