wanna run lp

[PiranhaAquaPhaze]

is the pmi turbo valve or the spyder turbo valve ne different, is one higher flowin that the other?
also for the lpc is the ACI chamber gona work or is there a better lpc?
wut is a good reg but under 70$?i dont like the pmi pure energy, i like the vigilante but not sure, never used it before
i appreciate the info

[Saiyan_warrior]

They'res really not that much of a difference between turbo valves. And a new low pressure chamber wont help you at all. As for the regs, the vigi is only good for nitro, not co2. Other than that look at Piranhapro's FAQ, everybody seems to be ignoring it..

There is NO diff between valves.

A new LP chamber will help you, aci is good.

Vigi is fine on co2, as long as you have an anti syphon tube or run remote. It might need cleaning and orings every now and then, but it will work.

[PiranhaAquaPhaze]

do really need a delrin bolt, the cheapest ive found it is 29.99 at www.copaintball.com, in stead of gettin a delrin or somethin lik that, cant i just tak e the venturin face off my bolt?

[flyingdeadbody1]

im not sure if the sts g2 comes with a venturi bolt...well im not for sure, PiranhaPro?

[Saiyan_warrior]

Yes the sts g2 comes with venturi bolts. Not sure IF you can take the head of the bolt out. Ppro said that its probably pressure fitted so not to sure if you could take it out.

[PiranhaPro]

Yep, its a venturi.

I think it is pressure fit, but I'll get the ***** out...you watch me!:D I will take pics, of course:)

[Saiyan_warrior]

I think im gonna try it tonight..Oh well if its pressure fitted who cares, ill figure a way around it, hopefully :)

[PiranhaPro]

I have my ways to get around the venturi head, it should come out smooth as butta!

Course these are my ways, me no tell till me do:D

[PiranhaAquaPhaze]

lol, im jus gonna take a mini torch and heat the side of it up, im gona see if that mite work
newayz, i think the chex mix was too salty

[MuckRaker]

Is there a reason why the venturi bolt won't work with the lp mod?

[PiranhaPro]

Venturi bolts block air flow, the thing needed for lp is high flow, low pressure. The higher flowing the system, the lower you can drop your opperating pressure.

The venturi will work with a LP setup, but you can drop your opperating pressure about another 60-70psi if the head it removed.

[MuckRaker]

So Pro, which bolt would you recommend?

[PiranhaPro]

Well if you feel like trying your luck the stock bolt will work fine. If you wanna try to remove the venturi head you could...

If you would rather buy something, I'd recommend a Shocktech Delrin bolt. With a small drill bit you can drill out the venturi and make it very high flowing.

I would recommend trying to remove the venturi on your bolt, if you do screw it up somehow you can buy the shocktech. If you dont screw it up, sweet!

I will take pics of my bolt mods...if it works I'll post it up.

[MuckRaker]

I think i'll just buy a Delrin bolt ... I don't have the tools or patience to mod the stock bolt.

[Hsuve]

The Shocktech Delrin bolt is pretty much a high flowing bolt. It has that venturi design, but it's like maybe 3-5mm thick of a wall. I'd still drill it out though, I'm so picky... ;)

Hi guys, I've been LPing Piranha's for a couple years and have tested most setups. The stock LP/ASA is fine for low pressure as long as its the real hollowed out cell or a ram air cell. Except the ASA is a little restrictive so it must be drilling/ported out. The new G3's should have the new high flow LP/ASA so they work fine with no mods. AS far as bolts go the Venturi is NOT restrictive and doesn't require the face to be removed, the face is there for a reason. The venturi's are capable of running at 200PSI or less, although this requires a fair amount of mods to the rest of the gun to get this low. Stay away from the delrin bolts for LP, o-ringless bolts don't work well at low pressures.

Check out this page for some bolt tests and info on how to do the porting job.

O-ringless bolts, such as delrin bolts, are great for LP usage. They're smoother than regular aluminum bolts, which makes it smoother. The smoother it is, the less friction. The less friction, the less force it requires for it to move alongside the body, or such. A venturi will help the gun recock, however, will result in lower velocities, as there IS an air restriction...

[Chrisb]

Did you look at the tests, I didn't just pull these numbers out of the air. Friction of the bolt has NOTHING to do with low pressure operation. The reason why the Delrin bolts require MORE pressure then a venturi is that they do not seal as well without o-rings and air escapes rearward.
The PMI venturi bolts will flow enough to run at 200PSI, my pro with the electro kit(required to get a long enough dwell) runs at this pressure and shoots 290fps, its a proven fact.
I'm not sure what your basing your info on so lets see the tests that you've done to back it up, I'm opened minded, I just need to see the hard facts.

[Hsuve]

It's just a clear fact. Microline will never be less restrictive of air than macroline. A venturi bolt is somewhat like microline. It's more restrictive of air. An open faced bolt, is somewhat like macroline. Now it's like microline compared to macroline. How is a venturi bolt, which takes up space in which air could flow though, work better than an open faced bolt, much like macroline? It can't. The reason why the guns can run at a lower pressure with a venturi bolt is due to the air restriction. Because air does not get through as quickly as with an open faced bolt, more air is directed toward the striker tube, helping it recock. However, the velocity will be lower, as less air is used on pushing the ball out... By the way, did I offend you or anything? You seem really defensive... :(

[Chrisb]

Oh no you didn't offend me, sorry if I came off too defensive. Its just that I provide factual information proving that the delrin bolts are not the greatest for LP and you seemed to ignore it. No problem understanding the Flow thing, bigger flows more, thats a given.
What I was trying to get across was a couple things.

-because delrin bolts don't have o-rings they don't seal as well and in turn leak air out the back or up the feed tube or where ever, but some is lost resulting in a reduction of velocity or the requirement of more pressure. This has nothing to do with the flow rate of the bolt.

-Second was that, yes a wide open hole will flow better then an opening with holes in it but the venturi flows more then enough for the pressures we are working with, and the benefits of the face are worth keeping it in place.

Thats my two pennies anyway

[Hsuve]

Mind if I ask what the benefits of keeping the venturi in are? :)

[Skelo]

Does anyone know if the co2000 regulator(the new version) is any good?

[Chrisb]

The face distributes the air evenly on the ball as well as cups it during firing.


I haven't personally tried the CO2000 regs but they are liquid safe (about the most important thing) and from what I have heard the flow is good so from that I would think they are alright.

[Hsuve]

Destribues air evenly? An open faced bolt would do the same. Cupping the ball? A venturi is usually inside the bolt, and not at the very front, where the ball touches.

[Chrisb]

I am just talking about the Face of the venturi(wasn't that the issue from the start). The stock open face bolts do not distribute the air evenly, the defuser pin is an attempt to stop the full brunt of the pressure from hitting the center of the ball (the weakest spot), the venturi does this in a better way by using holes, less air comes through the smaller center hole and more around the outer edges where there is bigger holes.

[PiranhaPro]

Actually I just thought of this...

If the venturi bolt has a face on it (such as a Piranha bolt) the air goes straight through the bolt and hits the venturi head. What's to say the air doesnt just take that same straight circlular pattern right on past the venturi holes? I dont see how the air would catch the venturi head, then all of a sudden go in 8 different directions...


This is hard to explain, I hope you know what I'm saying. Im trying to say that I think the air goes right on past the venturi head, without being "dispurst" among the holes. Thus, the venturi is useless.

I have no tested this in any way, in fact I just thought of it. However, it makes perfect sense.

[Chrisb]

I would think that the air has no choice but to be split between the holes, and the volume of air through each hole would be dependent on the hole size. Now once the air has past through the holes it would then probably just combine and work as one to propell the ball.

Try runnning some water pressure through your bolt, I know its much more dense then air but it will kind of show what effect the bolt has on the air travel.

Good idea! I will try this tonight, and post a response either late tonight or tomarrow.
