I deflated all 4 tires to 10 lbs, it took 2:30 to inflate ALL 4 37in tires to 30 lbs. My compressor is 5 CFM@90psi to compare to yours. I had some of these parts so it was cheaper for me.
1: 1-50ft of 3/8 air hose- Home depot 13.00
2: 4-lock-on air chuck (closed)- Amazon 10.81ea
3: 3- Barb “T” 3/8x3/8x3/8- Home depot 6.00ea
4: 12-1/4to5/8 hose clamps- Home depot 5.00 a bag of 10
5: 2-3/8 barb to 1/4ntp brass-Amazon or home depot 3.60ea
6: 1-1/4x1/4x1/4 NTP brass “T” Amazon or home depot 7.00ea
7: 1-1/4NTP valve-Amazon or Home depot 3.50-7ea
8: 1-1/4x1/4 brass barrel- Amazon or home depot 3.00ea
9: 1-1/4 NTP air gauge rear mount-Amazon 10-20.00ea

I had a lot of this stuff laying around besides the hose and air chucks to complete it it was pretty cheap but going out to buy everything can be upwards to 100.00.

I'd agree. I've also found that if I get them dialed in for at home (DFW area) they are fine until I head someplace like Colorado with a completely different altitude/elevation, at which point they are off by several psi it seems. I have to fiddle with them too much....I now just set them to keep going and I watch my TPMS till I'm where I want to be.

I used one of these as well in the past. They work good but really depends on the wheel you have. Some wheels don't give you enough space to get that large of a contraption on the valve stem. Fuels wheels seem to make these units a pain.

I really like what you've created here. $100+ is a little pricey, but as you said....if you have a lot of the parts already laying around this seems like a great route to take!

I'll have to build one of these, my compressor is 10.2cfm @ 90psi- 60 gallon tank that sucks 220v, it should be able to make the same numbers you've got. Thank you for the list of parts!

the key is a good air chuck so air doesn't leak. This is what I use

I have a Powertank with a Pro Series Superflow Regulator Kit. Usually I have all my 40's air'd down or up before guys finish 1 tire using a compressor.
