There seems to be NO clear cut answers as to the how much psi/per turn on the regulator. Without a gauge to see, it’s speculation and through all my research, 2 diff video and 1 post on here all have differing answers. A full turn = 100bar in one video, another says 120, on one of thr forums here, a user said 130-140. Does ANY AEA Challenger/challenger Pro have for sure documented evaluation while adjusting their regulator? It’s nuts that this info isn’t readily available since there is no gauge to tell you in the regulator.

There is probably nothing definitive because there are probably differences between each reg. Meaning production tolerances in this cost bracket is pretty loose.
Let’s say for example though there was a definite turn/bar adjustment, how would you know the initial setting without a gauge (or a definite ‘fall off reg’ point). If using the fall off reg point, you could determine a close approximation for your reg.
Does this gun have a gauge port for reg air?

Yeah this makes sense. The challenger pro does have a gauge that shows reg pressure. Guess really the only way will be trial and error. The further problem with it is I think you will probably find if you lower the reg much you are going to be quite a bit over sprung even with the softer supplied spring. One day I’m confident that AEA in their pursuit of just pouring out different models will slow their role and improve on existing products with the simple introduction of an adjustable hammer spring.

Yeah, it does not. The challenger Pro has a guage but the aftermarket regulator made for the challenger standards do not. I bit frustrating.

1/8th turn is about 2 mpa
I actually adjusted my reg from 2400 psi to 2900 psi a few weeks ago and estimated it exactly right using that measurement
This is also what Bin Lu told me from BinTac. Turning left increases the pressure. Do not increase beyond 21 mpa, that is max safe pressure for regulator.

Thank you! This is what I was hoping to hear, not only that this equals that, but I verified this. Is this the challenger pro? Thus u know for sure?

Yeah just make sure you see I edited my post... 1/8th turn to the left is +2 mpa ... I just checked my messages with Bin. That's what I used and I only had to do it once, right on the money. I have a Challenger Pro 30.

Man, all I know my friend Scott did some tuning on my pro .35 and it shoots lights out! It eats fx hybrids at the tune of MOA or better and 1100+ fps. Flat shooting and hits hard.

Convert PSI To MPa: PSI To Megapascal Calculator + Chart
In many cases when working with pressure, you will have to convert PSI to MPa. Here we will learn how to convert PSI to MPa (MPa are much bigger units). To help everybody out, we have designed simple-to-use PSI to MPa calculator (insert PSI, get MPa) and included the PSI to MPa conversion chart...

These guns are no joke. Wish it was a little lighter and maybe a more traditional look, but the power and adjustability is something else. Max power I've got on my 30 cal Challenger Pro is 138 fpe. That's with the regulator set to 2900 psi and 61.5 grain NSA .303 hollowpoints. (heavy spring installed... although I find the springs don't make a lot of difference between the two)

So that’s right at 1000fps. I was told that someone said bin said max reg pressure is 3150? Anyone else heard otherwise?

Darn that’s going to be hard withiut gauge and knowing that regulators are going to have differences

That's why I turned mine to 2900 psi. I don't see a need for a couple more FPS trying to hit the limits. I'd rather give the limits a bit of a margin anyway.

so based of your measurements, 1 and 1/4 should get me right around 2900 then right?

No don't do it that way. Look at your regulator gauge to see what your pressure is now. It's probably around 2700 psi. But whatever it is, adjust from there. Probably the max you will be turning this is 1/4 turn before you hit the limit. It may be less than that. I turned mine about 3/16ths based on my calculated adjustment. Measure, do the math, and if you're not sure come back here and ask for clarification. I don't want you to blow out your regulator.
note: Obviously you need more air in your tank than regulator is set to, otherwise the regulator will show a lower pressure. Make sure you've got at least 3000 psi in your tank when reading the regulator gauge.
Then use the regulator gauge (not the main gauge on the bottom of the tank) to degas the gun. I assume you know how to do this, but just unscrew it enough until you start to hear hissing. After a while the hissing will slow down, you can unscrew it just a little more. Keep doing this until all the air is out. Once you're done adjusting the regulator, be sure not to overtighten the regulator gauge when you put it back in. Snug with a wrench is good, don't torque it.
Also when you screw the air tank back on to the regulator, make sure the fill probe hole is aligned exactly with the space in that chrome-looking metal thing on the bottom. That will probably mean backing it out just slightly from being screwed in 100% tight. If you don't do this, you'll have issues inserting and removing your fill probe. Once you fill the gun with air pressure you won't be able to adjust this, so line it up first.

1/8th turn = 2 mpa = 290 psi
So if you are at 2700 psi and want to get to 3000 that's pretty much 1/8th turn. In no case would you want to turn it a full rotation or more.

So I don’t have the challenger pro, I don’t see a gauge on the regulator that is aftermarket for the regular challenger
