York vs electric compressor vs CO2

It's all about the data, baby!

Without data you're just another guy with an opinion.
 
Does the co2 bottle lose cfm as it drains, or does it suddenly just give out when it's empty?

Has this been answered? I'm curious as well.

it goes honest york/arb twin together > CO2 with 50 dollar back up > viair or arb single > 50 dollar special > gas station

I'm going with option B.

Just picked up my 15 lb Co2 setup from IAS.

More data:

The mfg. claims a maximum of 4.25 CFM.
Here is what I get, about 2.25 CFM (open output, 1/2" line from compressor into to 1/4" fittings)

have you tried going to larger output fittings?? I know even my home compressor switching from 3/8" to 1/2" I gained a lot of output from my at home setup

i can say my CO2 tank costs me 18 dollars to fill, it fills my 37s from 0 to 40 in around 1.5 minutes, if the regulator freezes it takes a little longer, now that said at a 1/4 tank its output is probably 3/4 of what full is

I also have changed all my air hoses from 1/4 to 1/2" hose setup

I always have my backup compressor though
 
What's the voltage at the pump?

This is with the compressor running, it drops the battery voltage about 0.8V.

I'm running about 10' of #4 wire into a distribution block, then another 6' of #8 wire to the compressor. One day I'll upgrade that #8 section.

Short 1/2" line to 3/8" manifold to 1/4" air chuck. I don't see where I could use larger fittings.

Increasing your chuck size could help out for sure! Its usually a huge limiting factor in tools and air flow

i should add some manufacturers also call them "high flow" chucks

I was thinking about that, but seeing how my flow meter with 1/4" ports doesn't offer any restriction below 4 CFM, I wasn't too concerned about the air chuck.

Now the 25' of hose on the otherhand....

All of the OBA stuff I've been building and have available is all based on 3/8" hose but there some spots where you don't have a choice and stuck with 1/4" such as the tank.
 
Lc ,these cfm figures are difficult to compare. For one thing, there appears to be wide uncertainty as to the definition of "cfm at 90psi" given by comp manufacturers and you can be pretty sure the manufacturers are using that to their advantage to inflate numbers. It seems that in some cases at least they really are " tank volume going from 0 to 90 in the tank" rather than "true acfm being delivered continuously at 90psi" as one might assume. Since your gauge is supposed to give scfm -and these float gauges are not that accurate- that may well mean something different since it is measuring it likely as acfm at the pressure in the gauge and reading as scfm, which would be a different set of conditions compared to the manufacturer's claim. Conjecturing here. Anyway, it's a mess, so I would not worry too much about the absolute numbers.

You will notice a slight decrease in inflation speed when the bottle is very low. Performance stays pretty constant until the end.
 
can't realize I did not figure this out sooner but here goes, how important is it that the engine is running when using an electric compressor. Was looking on amazon today and saw that even viaair reccomends that the engine must be running when the compressor is running. I guess I just never thought of the idea of difference running vs. non running. I plan to test out the voltage compared running vs. non running shortly.

It makes sense. The most you'll get without it running is the max output of your battery. With it running you are limited by your voltage regulator, so even with a high output alternator you're going to get simewhere in the neighborhood of 13.9 V best case I woukd think. Isn't it more about amps?
 
I like your setup, did you create that plastic plate and block or buy from air zenith?
I made the plate, the manifold block is from McMaster Carr.

I saw the flow go from 2 CFM with the engine off to 2.25 CFM (unrestricted) with the engine running.
 
in my younger and even foolisher days, I bought a whole bunch of QD fittings in a bunch of sizes from 1/4" to over 1/2". Mostly used 1/4" to date, sadly. But the big ones are pretty sitting there on the shelves if not put to good use. I didn't bother because I imagine that the gains with those are likely significantly smaller than improving the hoses or piping, although I did not test that. Plus the inconvenience of having to use adapters.
