DM3 Test Bed

[Roger7pball]

Ran some HPRs and LPRs on the DM3 rig for recharge rate testing at 11 bps....

AKA vs CP vs DYE HPR

• The sidewinder ran great on the Angel rig at ~400psi but for some reason doesn't do well at ~150psi. Not sure why as it's quite new. Either my spring stack is wrong or the reg's ideal pressure range is higher.
• The Hyper2 regs do the best on my Angels and on the DM3.

AKA vs DYE vs Toxic LPR

• The AKA lpr did the best on the Angel and the DM3.

Take these plots however you like. Just having fun engineerding.

Always enjoy seeing these graphs. The LPR test.... The Toxic looks like it recovers well, but the drop between shots being so much further of a drop. I am guessing it probably has a smaller volume of regulated air so when air from that volume is used it drops pressure further then if a larger volume was present? Does that make sense? Need to get you something from like an Air America Messiah or vigilante. Had great reputation 20 years ago and just wonder how they compare to modern regs.

Yeah that does make sense, and could be true. I should note that on that LPR I had to make a Jackhammer reg seat work since I couldn’t find a replacement. But that shouldn’t affect anything but overshoot I believe - could be wrong.

It really doesn’t take me long or much effort to set up the rig if anyone has stuff they want tested.
