the EC can act as a volumizer, so long as pressure stays high. Older VM's had a much larger empty space behind the front ASA then earlier ones, and tend to work better, from my experience. If they have the big gas transfer port then they should have the bit more space behind the ASA.

its been ages since I messed with running VM's on HPA . . . and at that time I used a regulator and played with lightening the cycling mass of the VM. Ultimately, using CO2 has been the simplest way to run a VM. And with VM's simplicity is the name of the game. heck, none of my VM's even have valve springs in them

Yup. That is the first "mod" we have done to all of ours as well. You just hear the cup seal rattle back and forth in it. Just get a 20oz tank and hopefully it will make it threw the day for you.

Dayum! That is a monster. And with an Intimidator, too. Very nice.

Can I be in your will?

toss the valve spring out. saves about .01oz of mass!!



seriously though - you don't need the valve spring. Typical basic VM stuff . . . take out the valve body, drill out the smallest gas port to be the biggest, conveniently lose the valve spring prior to reassembly . . . reassemble with your now mega gas port in the 12oclock position

heh, the last time playing up at Jungle Island the ref watched me chrono my $20 wonder VM and it was always within 5fps shot for shot, on CO2, with just an expansion chamber. thats good consistency for a aluminum brick

Bored,

Humor me on this. Get a full CO2 tank. Gas up the vm-68 that has the black rain on it and submerge the black rain part of your vm into a bucket of water. Do you see any longitudenal stress fissured spewing c02 bubbles from the black rain Exp Ch.?

Every Black Rain I have seen, about a large flat rate box full of them worth, have stress cracks that leak CO2 from them when pressurized.

Long story short, we used to have a ton of them on the vm-68 loaners. And they all did not come from the same place. But each demonstrated leaking from hair line cracks in the Black Rain exp manifold.

EVERY one of them.
