I need help with air efficency
 
I have a psychoballistic superbolt with a ccm deluxe kit. The gun shoots amazing but has a horrible air consumption problem. i heard pumps were supoosed to be very effecient on air but i can barely get a hopper off a 68/45. I have an AXC spring kit with the heaviest spring in the valve and medium light for the main spring. But to no avail it still goes through tanks like no other.
I have a ninja pro tank and do not know what would be a could out put pressure to have it at, it is stock set at 800 psi. Otherwise i have no clue what to do on how to make it useless air.

If someone could help me that would be amazing

Pumping through a 68/45 wears me out.

It was going to be a picture thread, but it has some good points to it....

I would check the bolt o-rings and barrel first. It's easy to check. Shoot it in a safe direction with hopper off and an extra ball in the feed neck. How high it goes shows you how much air you are loosing there. My first superbolt would pop it over three feet up.

Part of it was the bolt o-rings were off spec and didn't touch the bore at all. The other thing was that the non-stock barrel didn't screw all the way in. Leaving that gap allowed the ball to roll away from the bolt face as well as letting air escape around the bolt face. That's a pain to fix if you don't have the tap.

Iirc, the stock valve is ported a bit tight (maybe for CO2). I drilled it out to match the port in the body and bolt.

Before we assume too much, is it regulated?

Are you running a regulator on the gun and did you sweetspot it?

Welcome to MCB!

it is regulated and all and i have a freak kit but it still just goes through air like its nothing

After sweetspoting the reg it is still inefficient? Is it possible you have a leak somewhere?

pbalien73 05-06-2013 09:14 PM

Sounds like a leak, I get a hopper and 4 pods on my 45/45 on all of my pumps. I can't see how you could shoot all the air out of a 68/45 especially regulated and strong valve spring. I would listen down the barrel and brush soapy water on all the fittings, Asa and pump rod. Let us know what happens.

no i have not sweet spotted it

What pressure is it set at? You want your regulator to be at its most efficient, which is what the sweetspotting accomplishes.

BiggsFX 05-07-2013 10:59 AM

It has to be a leak. Even a reg that isn't sweet spotted wouldn't be that bad (reg should be in the 300-350 range). The psycho internals aren't the best. Its probably leaking at the valve.

about how far would you guys say the IVG should be screwed in?
