Gas Hog on Speed 05

[cakes]

My angel speed 05, with the stock reg, Trinity ASA, Stiffi Barrel And a Virtue board. My gun eats gas for breakfast lunch and dinner. I lose around 1700 psi on one hopper. It is a dye throttle tank with a Guerrilla air Myth reg. I tried turning the velocity down and it still eats gas. I dont know what to do. Please help

What is your dwell set at?

[cakes]

i dont know, what should it be set it so that i can see if that is it

[cakes]

right now it is at 14

Turn it down to 9 and play with it there.

Yeah, 8 or 9 should work great and increase your shots per tank. My guess is that you'll see a dramatic increase.

Dwell controls how long the hammer is in the forward position (technically, it controls how long the solenoid is in position to send the ram assembly forward, which is longer than the time the hammer's in the forward position due to travel times, but that's not particularly important here, plus this parenthetical is already far too long). If the gas immediately behind the paintball is already pushing the paintball as fast along the barrel as it can go (or, at an extreme, if the ball has already exited the barrel!), holding the dwell open longer conveys no benefit, but does exhaust a great deal of gas out the poppet valve at main pressure.

If adjusting the dwell down negatively affects your gun, keep in mind that you typically need to adjust one of the following up to compensate:
1) LPR pressure. All else being equal, higher LPR pressure means less travel time for the hammer/ram assembly, and thus more time spent actually exhausting gas. Of course, keeping the same amount of time spent exhausting gas means you've done nothing for your gas usage, so try adjusting...
2) Main pressure. Higher main pressure results in more initial force being imparted to the projectile, and provides a greater "reserve of pushing power", so to speak, with which to offset the reduced time period where the main pressure is being exhausted behind the paintball.

Still, I'd suspect that in your case you can get away with a very minimal adjustment to main pressure, even alongside a quite-large adjustment to dwell. You're throwing a bunch of air down the barrel after a ball that's already going as fast as you're likely to get it going.
