Making a pump quieter - Page 5

Ok... The reason we call it "Ninja mode" is because it takes years of strenuous training to get there.

So stop spilling the beans, guys.

That said:

The spiral ported deadlywinds are quieter than the Carter Woosh.

CO2 is quieter than HPA.

Low pressure is *easier* to make quiet than high pressure.

The reverse is true in conjunction with a rain cover.

NEVER EVER EVER EVER run more than 285 fps. And don't be afraid to go lower if you know your kills will be closer. I often enter the field at 245 fps, since I often engage at 20 feet or less.

High pressure guns can actually be extremely quiet: the quietest gun in my fleet is a Retro 7 with Zero barrel... it simply never informs the other team they are under fire until they are dead, or I miss and hit their bunker instead. My finest and quietest tuned LP guns can't even touch it, although my Illusion comes close, and it's also set up with a Zero barrel (which is quieter than my straight-ported Deadlywinds).

I did say easier... I tune by breech pressure. It's a lot easier for someone to get a low breech pressure with a lp gun. It's not impossible to get that same result with a hp gun... I just use a $300 tool to do it. Without, you're just guessing.

Actually, I specialize in guessing... no fancy 300 dollar tools or guages for me

Interesting, please do explain

because the rain cover acts kinda like a silencer, not relying on porting so much or the force of the pressurized gas escaping like a lp setup would? In other words, lp isn't any easier to get quieter than hp when using a raincover?

Mind you, that was just an uneducated guess

i am trying a Palmers LT valve today and will report back on how it compares to a stock valve with Madmann sear spring/CCM hammer spring. so far, it seems to be about 30-40 FPS lower at the same reg pressure (225) and IVG setting (flush). the valve stem is slightly longer than a WGP stem by a couple millimeters.

toymachine · 11-24-2012, 11:24 AM

is it an hp lt valve or the lower pressure variety? I honestly never had any real luck with the non-hp pps valve

gospeedgo1 · 11-24-2012, 10:54 PM

it is the lower pressure one. while it did change the farting to a nice tight pop, it was not as free flowing as the stock valve or as quiet as i hoped. i may try to run the Palmers stem with the stock valve body.

How do you define free flowing? From past experiences, would you be able to compare it to other well known valves? ie. Rat, CCM, Checkit, etc.
