Audrius regulator questions

[eezapz2101]

So I'm considering getting one of these regulators from eBay

Does anyone has one in a gen2 marauder .22?
What is the best pressure to have it at?

I have one in my .22 cal Armada. Same action as the Marauder. The best set point depends on what you want to do with the gun and what other mods have been done. I have a Tim Hill valve, light weight hammer, gauge block etc... The TP port is .161 and the barrel has been drilled to match. I have my Audrius reg set at approx. 95 bar. Getting 70+ shots @ 30fpe per fill with JSB 18.13's.

Wow 70 shots and 30 fps with 18.13 jsb wow that's amazing
The only mods I plan on doing
Enlarge airstriper ports
Install WAR TSS.

Why did you change the valve?
Light weight hammer? Witch one and why?
Gauge block what is that?

TP and barrel drill to .161 but not the valve? How to know what size to drill the port and barrel? I mean other people ar drilling to .187 more or less but still I don't understand now that relates to the regulator, TSS and other mods

I put the TSS in and I'll probably get the MDS just to smooth the cocking. I should have time to get the chrony out this weekend and fine tune it. I've just been enjoying shooting it. Be nice to find a deal on the MDS like I did the TSS

Here's my build thread. Many photos and explanations there....

All the internal parts except the regulator are from Hill Air Guns. Here's his site...

These look like decent regs, I've been checking them out, I thought thats the kind that you had Terry but what I'm wondering is how good they'd be for something like the .25 Mrod, they do have a larger plenum and it doesn't look like this reg will go as high in pressure like I would like.  I'm sure the Huma would however they're quite a bit more in price than the Adrius.

 I have used several and no problems do wish they would have one with a gauge port. David

I bought the Audrius on Tim Hill's recommendation. I have one for my .25 build. I'll put all those parts in the gun as soon as Tim has gauge blocks back in stock. Given how low I have the reg set in the .22, I feel like it will work fine in the .25.

What does the gauge port do?
What is it for?

[avator]

If I'm not mistaken the reg takes up space in the air tube. If they had a gauge port you could take the existing gauge block out and replace it with the reg and reinstall the gauge without losing any tube capacity.

The gauge port holds the gauge. The Hill gauge port has a much larger flow through hole than the original. Helps to add to the plenum volume.

This is true but you also loose plenum space. Probably not an issue with a .22 cal but as you go up in caliber or power you need more plenum. Everything is a trade off.

[FuzzyGrub]

FWIW: a Hill gauge block and Audrius reg has more plenum than the Huma 25 cal reg w/integrated gauge block.

What benefit does using the gauge block have vs not using it?  Is it just to know where it's set at pressure wise and make adjustments easier since it just shows regulated pressure or am I missing something. 

Trying to figure out this regulating thing, so much information out there.

You are correct, but the more important item is the plenum size.  If you get rid of the gauge block and slide the audrius against the valve, you may not have large enough plenum for the power you would want in a 22 cal.   It is probably sufficient for a 177 cal, if you hog out the valve to 1/2".

John has it exactly right. There has to be a sufficient amount of air behind the regulator in the valve, gauge block, and whatever plenum space there is attached to the valve to actually make the shot. Retaining the gauge block, especially one with a bigger through hole like the Hill block adds additional space for that stored air. Of course that is at the expense of available air in the reservoir as all of that takes up reservoir space. In my case the 215cc res is more like 190cc after the reg is installed.

Stock gauge port on the left. Tim Hill's gauge port on the right.

Is there a difference in materials between the two, asides from the color?
Could I just take the block to a machinist and have him bore out the material with out having to spend more money with the new block?

There is more to it than that. There is a boss inside that is threaded for the gauge so the hole would have to be bored off center. Beyond what I have the capability to do but it has been done by many that have the equipment/skill to do it. I just ordered one and called it good.

Ok great
Now what about the valve it self what are the differences between the stock and the hill valve?
I understand you installed the whole hill tune into you're rifle right?

The Hill valve has much larger ports and also uses a very light (6 lb.) poppet spring. All of these pieces have to be matched together in order for it to work. I bought the matched parts kits from Tim so everything would work in unison.
