the blastfire mod on this page this page says it messes your gun up if you plug up the pump on the new blastfires.
how do you tell apart the new and the old blastfires and does it mess it up if you have an old blastfire?

[IronRhino]

Well, if you don't remember what the kind of fucking box it came in, you can tell by the spring in the upper left part (that you pull back). If its a big old thing, its the new version. If its a small little thing thats a bitch to put back together, its old. I'm pretty sure thats it.

i do remember the box and you could see it without opening it
(i remember cause i got it from ebay recently

The open box versions are the older versions.

Be sure to tell us how it works when you finish it!

Don't plug the overpressure release valve. It'll fux0r your gun.

i dont get why it messes it up if you plug the pump

Basically, when the pump is plugged, there is often an extrusion of hotglue on the back of the pump, over the air release. This pushes the little rubber membrane (looks like a tack in the diagram) out of it's place, disabling its ability to prevent backflow. If you can avoid making that extrusion, you probably won't have any problems. I didn't.

Zero, sometimes you scare me.

Earl, drop the image from your sig please.

[earl the bunny]

what is sig?

[wtrent10]

I'll answer that before people make fun of you for it. it's that little caption after your posts. like mine says "I am a taco salad".

Actually, that's NOT the reason it messes up the Blast Fire. The reason is more complicated. With blast fires, when you pull the triger you incrementally force a plunger into a tube, which uncovers holes leading to the barrels. Through a system of valves (which I won't go into here) the uncovering of a hole causes the corresponding barrel to fire. When you plug the pump you raise the overall pressure in the gun, not just in the barrels but ALSO in the plunger tube. This makes it MUCH harder to pull the trigger, and if you don't pull it ALL the way the plunger will ratchet back to it's last spot and not advance to the next barrel, essentially misfiring. In all other guns plugging the overpressure release valve is fine, but the Blast Fire's firing system is designed to work at a specific pressure.

[Zero Talent]

So the problem you're all suffering from is weak finger muscles? I just heard "broken after plugging" and "will no longer hold pressure," and this is about the only explanation for this, given higher pressures will sooner spring a leak than truss up the valve system behind the barrel. As I said, I've never had a problem with plugging the pump (and pumping 11 times), and this explanation was formed from multiple testimonies and my own personal experience with a Triple Strike, which uses the same configuration as the Blastfire, just on a different scale. I'm sorry if I mislead anyone to believe I am the God of Blastfire diagnosis.

[Spoon]

The Triple Strike, IIRC, fires all three shots at once, how is that the same mechanism as the BF?

Your explanation is definately a potential problem with plugging the pump improperly, I just don't think it's the main reason the BF sucks after being plugged.

[Zero Talent]

No, the Triple Strike can fire all three shots at once, much like the Blastfire. The entire thing relied on the same plunger mechanism as in the Blastfire, but in this case, it was the trigger, rather than part of an advancing mechanism hooked to the trigger. So, you could fire 1, 2, or 3 shots, depending on how far you pushed the trigger. Think of simply using that plunger in the Blastfire as a trigger, with no racheting advance.

Anyways, I can't see your problem... My friends and I have together modded 4 Blastfires (3 "old," 1 "new"), and plugging the pump only led to improvement. Sure, the trigger pull gets a bit exhuberant, but the pressure delivered to the dart does, though slightly, increase, and thusly does range. If I can get a hold of an unmodded Blastfire, I'll see if I can prove this. Until then, I'd recommend the community listen to the majority, and not plug the pump in the Blastfire.

I apologize if I sound insulting, this is just a very odd situation.

[Spoon]

Ok I see what you're saying about the Triple Strike (I don't think I've ever opened one up), and I can see how plugging the pump would work for that.

The problem is really the ratcheting mechanism. With the BF's that I've plugged, the problem isn't that the trigger is too hard to pull, the problem is that if you don't pull the trigger ALL the way and then release it ALL the way it will not advance to the next "tooth", and therefore won't advance to the next barrel. The faster you try to fire, the worse this problem gets. When the pump is not plugged, the pressure in the plunger tank is at a kind of equilibrium, where it doesn't actively try to force the plunger back out, like it does if you've plugged the pump.

I think the problem is really that these problems exhibit themselves worst at 7-8 pumps, whereas the gun will work relatively normally (plugged) at 5-6 pumps, but offers virtually no improvement over non-pumped guns in terms of range.

[Zero Talent]

Alright, I see what you mean. I never really noticed any "equilibrium" before the mod, so it was all normal to me. I do agree, the trigger mech can get jammed if you don't pull the trigger all the way, and release all the way; If you don't get used to full trigger pulls, you'll have problems. I modded it the day I got it (after a bit of unmodded shots, of course), so I never really noticed a difference, and never experienced any "problems." Thanks for the enlightenment, Spoon. I'll have to note that on my web page.

[Spoon]

It's weird though, because others have reported success with plugged BF's, I wonder if it isn't a universal problem.
