If you can get more air to flow behind the projectile, velocity and power should go up. I am not specifically familiar with the Logun Eagle- but taking it apart and looking over the valve may give you some ideas- lessening the valve return spring tension, expanding any ports/flow holes, lessening any restrictions in the valve passages, etc. etc. PCP and Co2 guns operate on essentially the same principles- so if you look over any Co2 valve modifications for power- the idea behind them would be the same for a PCP gun. Anyone have a parts diagram/layout or pictures of the valve/regulator for the Logun Eagle? _________________ ` I'd say "I care." But I'd be lying.

Some times this can have great effects on accuracy. CW   Posted: Thu Mar 20, 2008 4:58 pm fiestarter00000 New Member Joined: 01 Mar 2008 Posts: 6 cw wrote: You can also try to improve lock time.

And- good luck and let us know how you make out with it. Do you have a chronograph to be able to definitively see improvements? _________________ ` I'd say "I care." But I'd be lying.
