Hmmmm! Very interesting...13 pumps for a 1000 psi charge? Hardly enough pumps to create much heat I wouldn't think. That's one crafty Cajun there boy! Can't wait to hear what others think about this assist set-up. Let's hear it men...

Looks good in theory...That is the the air inlet he hooked into, but I would be worried about moisture or oil getting in my gun. Basically he turned his Benji Pump into a Shoebox....You guys can try it, I will stick to my pump/scuba tank

Very interesting! A crafty guy. If you had a good moisture/oil filter/trap on the compressor, like if you were spray painting, might be worth trying. To make it more portable, wondering how far one of the 5gal portable tanks would take you?

In the video you can see a water separator and regulator setup on his shop air. Ol boy has a pretty nice shop too.
I've heard of it being done. First time I've seen a video. It would be interesting to see how long his pump holds up to the typical bengy pump.

I'd be willing to bet that it'll hold out longer than a stock pump due to less wear on moving parts, maybe about the same or a little less heat generation. I'd also be willing to bet that if a pump manufacturing company saw this they'd be at least interested in developing & marketing it, at an increased cost as a deluxe/improved model of course. I wonder if it might be able to be used to efficiently top off an 88 cu ft SCBA tank.

Am sure it worked just as shown, have been others who proposed that system, but he's the first vid I've seen of one at work. Pretty neat.
Have some questions about longevity, not so much about the final stage as the initial stages of the pump. Would have to run one that way for a time and see what blew/wore/leaked. Probably does run a little cooler (the shop compressor would take some of the heat when pre-compressing the air).
Basically, its as if the pump was being worked normally in a world where the atmospheric pressure was 50psi (3.4bar) instead of 14.7psi (1 bar), so filling takes about 3.4 times fewer strokes (13 instead of 44 strokes).
Got to be big guy...didn't seem too bothered pumping one-footed.

I would really like to give that a try, any one have more info on pump life after that mod? Both my guns fill to 2000 psi and all I use to fill them is my hand pump, cutting the pumping time down by that much would be great. Thanks for posting the link to the video pelon87.

Did you guys check his other videos out? This guy is pretty ingenious...He made a disco double tube out of a paint ball tank!!!!!! I am seriously worried about his safety in this regard

I noticed two things.... One, he used a FUEL FILTER, I don't know if they are rated for 50 psi.... Secondly, he didn't complete the last pump at (almost) 2000 psi, so I'm guessing that was all his weight could handle....
I too have seen the idea before, and in fact I tried it and found the extra effort considerable, plus it's weird to have the handle driven back up on every stroke.... I don't see a problem with it otherwise....

I noticed that too BOB....That fuel filter might be okay for the pressure, most our modern fuel systems are under like 100psi. But that looks like a Carburator fuel filter which is normally under 10psi.
What do you think about the paint ball tanks?

CO2 tanks are rated for 1800 psi (at least that is what has been on the ones I have seen) and carry a 3K burst disc.... Therefore, they should be safe at up to 1800 psi, providing the connections are properly designed and they are not filled beyond that....
I really didn't like his first version, it would be too easy to break the threaded pipe fittings if you dropped the gun or even bumped the tank on something too hard.... His second version was a bit better, although the front fittings are still vulnerable to damage....

Wow....So basically everything this guy has done is correct in theory and practice. And since he is shooting a Disco he does not need to go past 2k psi anyways....
Again I say wow, I still am not gonna try either. He obviously reads the forums if he knows about the Disco Double, and a Tko. This guys should join the GTA!

If your asking about higher psi input to the pump, yea I don't see any reaso to say no other than physical ability. Remember higher psi going in drives the handel up. This means you have 3atm instead of 1. 13 strokes vs 44 strokes. The total energy expended to compress air to 2000psi is the same, its a matter of how big a bite of air your taking. Small bites=more strokes and Big bites equall less strokes. Same energy used over different amount of time. Work. Can you perform at the required level is the real question. At 225# feeding the pump 100psi I'd bet I would have a hard time getting 3000psi. Now, if someone were to come up with a closed system that regulated input psi to be high at empty but decrease as the tank psi approached fill, that would be kind of splitting the difference, thus lessening the total number of strokes yet still able to reach higher psi fills. Increase efficiency?

You should not post this type of stuff on the weekend, because I have time to do projects and payday was on Friday! I don't have any HPA tanks so I'm left with just my hand pump so the idea of SUPERCHARGING my pump seemed to be to good to be true when I saw the video.
I already have a good shop compressor and a hose with fittings so I set off to harbor freight with my son, I spent about $32 on filters and fittings then I had to make a stop at home depot and spend about $3 on some other small fittings.
I bought 2 types of filters, the one that plugs into the compressor is a oil/water separator then I put a desiccant dryer/filter on my hand pump and a air hose connects the two. I set the reg on the compressor to 50PSI, hooked my gun to the pump and the pump to the compressor and started pumping. It is defiantly harder to pump down BUT you really don't even have to pull the handle up as it raises from the incoming air pressure, I'm 6ft and 170lbs ish and pumping still seems easy to me.
I was filling from 1000psi to 2100psi and normally it would take me about 25 pumps but with the supercharger it took about 13-14, I would rather spend more time shooting then pumping any day! I filled my gun 6-7 times this way and I had no problems.
Sorry about the crappy pictures my wife has the good camera.
