Series5 efficiency question...

How many of you have decided to forsake a smooth pump in order to increase efficiency?
I'm thinking of doing just that. I play allot of outlaw, and I usually end up loaning the majority of my equipment out to others, which leaves me with just a 45ciX300psi. I think the best shot count I get from my set up is roughly around 275 shot's. I'm not 100% sure about that though, because someone else is shooting it instead of me.
Would increasing the valve spring tension be enough, or should I lighten the hammer, and increase reg pressure also.
Not really sure where to start.
Any help would be greatly appreciated, thanks.

mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...

I usually increase the efficiency by turning up the reg and increasing the stiffness of the IVG spring.

When I got my most recent S5, I was getting appx. 50 shots per 600 PSI. That's terrible. I turned the reg up, increased mainspring tension and I must have improved that by at least 60%.

It also seems to have decreased the "kick" noticeably. My assumption is that the valve stays open for a shorter interval of time, creating less of the "kick" feeling.

I'll also add that the pump stroke still can remain butter smooth, and you'd be hard pressed to tell if it was a stiffer stroke or not.

When I had a series 5 I replaced the valve with a Palmer's LT to increase efficiency... but it sure did change the pump stroke when I was done... More of a smooth SNiper than a ridiculously smooth CCM....

That sounds like the only result would be a higher velocity.
And Mar, why/how does a valve of such similar design, with the only differnce that the LT is made of brass, offer improved efficiency ?

But it isn't a higher velocity, because the valve dwell changes. When the valve loses dwell, you lose propellant. Therefore, you must increase the spring pressure to compensate for lost dwell in the valve. Simply a means of using a short dwelled burst of high pressure air, versus a long dwelled burst of lower pressure air.

It helps.

I'm gonna give this a shot... Though my son says not to.

Make the valve spring harder, and then sweetspot the reg, best way to do it. Don't look at what the gauge says, just let the gun dictate the pressure input. Too mnay times people get hung up on what pressure to run at, set the gun up right and the rest will fall into place.............

With CCM internals I've found that a red valve/green main and input pressure around 300 psi yields a very smooth stroke with great efficiency. It's not as light as the stock CCM stroke but it's very close IMHO.

It's how my S6 is running.
