setting your lpr pressure

[KEN CRANE]

ok lets go to the second most requested question.when setting your lpr on a lcd or ir3 follow the instructions as follows and you should be home free.first and most improtant,set your mini reg at 500 lbs.this is acomplished by using a reg tester.you can make one from a bottom line asa adapter and a pressure gauge from an air system.or purchace one from air america.

http://www.airamerica.com/guardian.htm

after setting the pressure at the mini reg. to 500 lbs check your lpr pressure using your wdp pressure tool.it should read 90 for a lcd and aprox 100-105 for a ir3.if your rate of fire is set low 100 will do.if it is lower add 1 shim at a time until it increases the pressure to the desired setting.if its high remove shims one at a time.if by chance you blow the lpr springs out or drop them they go back in as follows.)()(.then re chrony the gun and your off.i hope this didnt confuse things as i somtimes have a tough time putting things into words.

[acoenfam1]

Ken these are AWSOME ideas keep 'em comming.

[acoenfam1]

Hey Ken, just an idea but how about one on setting the Ram Stroke?

[Daylee-J]

Can you tell me,
How would i set my LPR pressure correctly if I Run my Angel AIR thru a gas thru grip??
Would it be best to put a mini reg on, set the LPR then switch the Minireg out for the Gas thru??

[KEN CRANE]

it shouldnt change your lpr pressure.you will need to set the velocity with the bottle.a good start is around 350.

[Daylee-J]

So i set the bottle around 350psi(or so im shooting 290 velocity). then set the LPR Pressure?, Correct?

[gremlin75]

Ken,

Sorry if this is a dumb question but why is it important that the mini reg is set at 500psi? I thought you needed to set the mini reg to a pressure where your speed would be at 300fps (such as you would without a mini reg but just AIR). Again sorry if this is a dumb question but my knowledge of angels is almost non-existent. Thanks

[KEN CRANE]

it sets the balance with velocity and lpr pressure for the high rate of 1r3 fire.and we have found it is where the tuning sweet spot is

[gremlin75]

Ok. Thank you.

no one has answered my thread in the other forum but i just gotmy angel air serviced and it wont chrono over 240?????? is this anything to do with this lpr cause cause i set my angel air above 800psi (thats right aint it?) and then kept on going up but it wouldnt work even when it read HI-P on it AIR reg so i figured it might have something to do with the lpr even tho my angel was serviced at the zap indoor a couple weeks before(birmingham ,UK)

[C.Carles-AOG]

Ladies and gentlemen, perhaps these questions would be better served in the respective gun forums. Lets keep this Tech Ref Guide as clean as possible. Just an idea...

[darkangellcd23]

sorry

i did and no one replied :(

[mbx1105]

Where can I get a reg tester? And how much are they?

[Syentific]

Check Ken's link at the top of the thread.

[Howitzer11]

Ken Crane rules.

[Aaresz]

I don't quite understand how to apply the reg tester (guardian) to the mini reg to test it? Or how would you adjust it to get to 500 lbs if it needed to be. Ken could you give further information on those steps please?

[gremlin75]

To put the reg tester on you need to unscrew the reg from the gun and screw the tester onto the top of the reg. Then to get it to 500psi all you do is slowly unscrew the grub screw (the screw you use to adjust the velocity) untill the reg testers gauge reads 500psi. Thats about it.

[MoogLe]

i have the exact same probelm as darkangellcd23 can anyone please tell me if it could be the lpr? i dont wanna waste my time on that for nothing

ken explained how to adjus the lpr but not what it for, like he did with ram adjustment etc. sorry to post this here

[C.Carles-AOG]

I'm having trouble understanding your question, but I think you mean to ask what is the LPR for(?).
As far as I can see it's for recharge rate, so you don't get shootdown. That's the short and easy explanation from what I have experienced when my LPR has been off. It's affected my velocity somewhat as well especially resulting in inconsistancy.

[MoogLe]

well that kinda answers my question, so can a badly adjusted lpr result in shot drop offs and low velocity? cuz i am currently experiencing these two problems, i had first shot drop off and tried to adjust my snap ring, now i did it exactly as explained by everyone and even let a friend double check it, but now instead of just getting FSDO my gun wont go past 250fps and i get more drop off, like after every 1 minute of not shooting the fist ball will moe like 2 inches in the barrel and i will just shoot 2 balls, think this could be the result of a badly adjusted snap ring? and oh yeah while adjusting the snap ring the ram also turned slightly, just a few milimeters but i turned it back some, and as i understand this cant be the cause anyway, although i will be doing a full tune up in a few days, i'm also thinking about cleaning my reg

[Emmit]

the drop off in a string is usually the result of an LPR being out of adjustment.

FSDO is usually a snap ring, or even an air supply (read minireg) problem.

As for the velocity not getting up, I'd recommend setting everything else right first, then seeing if you still have this problem.

[MoogLe]

thanks emmit, only thing is i'm not getting drop off in a string, its rather like FSDO but it occurs rather quickly, like after every minute of not shooting the first ball will be a dud

[Osmoosi]

Is the optimal IR3's tested tuning spot, minireg at ~500psi, good for tuning in the Speed as well, as their operating pressures are a bit different?

[Osmoosi]

ok i let my friend use my angel LCD "02 while i left for vacation and he used CO2 on my gun. I have recently attached compressed air in the ASA and now there is a leak. I opened it up and it seems to be coming from the LPR part but im not sure. I dont think i busted an o-ring but i am also not sure. What do you suggest the problem is and can you help me by listing some new parts i need for my gun.

is it leaking from the front of the gun or from the breach area?

your lucky your solenoid still works

[outcast]

Will the LPR adjustment steps presented here work for the new Fly's too?

[pimpinsaylor]

Will the LPR adjustment steps presented here work for the new Fly's too?
im not sure the a4's are low pressure and the ir3 and back are all high pressure gun's.

[outcast]

If you're adjusting LPR pressure on the A4Fly, should the tuning spot still be at 500psi?

[Emmit]

god no....read your manual please.

[C.Carles-AOG]

If I recall correctly it's 350psi to set it.

[outcast]

Okay I was off by 150psi. :)

[C.Carles-AOG]

In the SPEED manual it states 350psi on page 22. In the 4 manual it states 350psi on page 33. In the 4 Fly manual it states 350psi on page 17.
Seems like the new generation likes to be set at 350psi. :wink:

[outcast]

Well I guess you have a lot of guns if you got all those manuals. :)

Can you tune it properly without setting the mini reg to 350 psi? And what happens if you do it with, or without the volumizer on?

[Vantage_TeS]

Check your PM, all your questions are answered :)

You can tune it, just not properly.

Can't use gauge and volumizer at same time, so obviously you can tune it with it off.

[outcast]

I checked my PM's but nothing's coming through yet. I'm not getting email notifications also, so that might be the problem. :(

...EDIT...
Nevermind, it just came through. :)

[C.Carles-AOG]

outcast, I just click on the links at the top :wink:

Do you have to check LPR with a full tank of air? Would little air in the tank cause low readings on the LPR gauge? Also, do you have to adjust the mini reg to the "tuning spot" to check what it is out of the box?

Thanks!

[Emmit]

there's really not much point in checking the minireg's output pressure unless you're having problems with it, it's going to vary day to day depending on what your velocity is.

the thing you do need to do is figure out a way to get 350psi out of it if you don't have a testing rig to bypass the minireg.

I thought you needed to set the mini reg to 350psi to tune your LPR though?

Do you need to have a full tank of air to get the correct readings on the LPR gauge?

[Emmit]

the manual simply states 350psi into the LPR to set it properly...their terminology is something like "350 psi from a second stage regulator ...." well if you don't have a way to verify your minireg is putting out 350 psi you're killing yourself (ie no gauge on the flash tank like the 4's had) because under normal operating conditions the minireg is putting out more like 200 psi. I've got a rig that I built that bypasses the minireg completely and I'm able to put 350 psi straight into the Flash tank to set the LPR. I've posted pics of it before so you might be able to find them. I know most Tech's do the same thing, they've got set ups that they've built that screw directly into the flash tank and allow them to set the LPR accordingly.

As for a full tank...nah...1500 psi is way more than enough. You're not trying to play a game with it. Admittedly you'll lose a little bit of air but not a terrible amount.

[outcast]

Thanks Emmit!
Okay I asked how to make a regulator tester in another thread, and I was also told to just turn the velocity screw out until the mini reg is at 350psi. (when you have the reg tester on) Would this do? If not, is it alright to check and adjust LPR just straight with whatever the mini reg is outputting? (prolly around 200psi like you said) What would be the negative effects to this?

As for my tank, I only had about 500psi in there so I don't know If I got a correct reading or not. Because one time it showed a little less than 50psi on the LPR gauge. This was without knowing what the mini reg pressure was at.

Thanks!

[Emmit]

if you can't get a rig to bypass the mninireg then that's fine use the minireg, however setting the LPR with less than 350psi into it will result in poor performance IMO. Your LPR will not be set to it's optimal settings.

And 500 in the tank is probably too low, you have to have plenty of air to be sure your not only overcoming the output pressure of the tank, but also to keep up with flow rates which means you need to have plenty of air in the tank for recharge.

[outcast]

Cool, thanks Emmitt. I thought that 500psi in the tank might have been too low for a correct reading, but I just got the tool kit in so I wanted to try it out. :)

Okay so If use the reg tester(ASA w/gauge) suggested by some others to set the mini reg to 350psi, I'll be good to go? I only have a preset LP tank, so after the mini reg is set to 350psi, I won't have to do anything else right, like use a different input into the mini reg or anything?

[Emmit]

you only need the 350 for testing/tuning purposes. Once you've set the LPR go chrono and you'll have to turn your minireg way down. You don't want an output of 350 in a normal situation, that means your marker would be operating at 350psi instead of the 200 range. Set your LPR according to the manual, then go chrono your marker for play.

[outcast]

Thanks.
Is the ASA w/gauge a good way to get the mini reg to 350psi?

[Vantage_TeS]

Yup, unless you have an accual reg tester ($80) you can use the homemade one.

[outcast]

Hey guys, on TAG forums in the FAQ section it says that you really need an adjustable tank to set LPR. Is this true? Please don't tell me I need to buy an adjustable tank just to set the LPR right. :)

[Vantage_TeS]

No they said an adjustable so you could set it at 500psi. If you set the minireg to 500psi you dont need the adjustable tank. Just use the reg tester we showed you how to make and you will be fine.

[Speed Addict]

my minireg is reading about 350 psi... if i add a medium volumizer to my gun... will i have to adjust the lpr springs? or will it be fine without any adjustment of the springs?

[MORFEUS]

I recently got the Speed 05 everything seems to be great I installed a large volumizer cause it kicked a lot.I wanted to adjust the lpr so I checked my maunal(which by the way its great)and all the thread about lpr adjusting.I removed the right end cap and took out the brass piston just like the manual says,now according to the pictures shouldn't I be seeing the springs stack??The problem is I cant find it!!I know I'm such a damass when it comes to adjusting markers.When I put the gauge tool from the WDP toolkit and fire the thing starts to spin like crazy lol.I want to adjust it cause I see some blowback action and efficiency problems.The marker rips like no other but I know its better than that.So If you could explain it in simple steps how to adjust it I would be greatfull.Thanks for your time.

Every angelowner that has a MT near him is lucky I wish we had one here.They rule.

[El Pirata]

I you remove the brass piston there are 4 washers that are beveled, those are the springs. The manual shows these but may nor label them. After the beveled washers there are ultra thin larger washers which are the shims. Each shim will raise or lower the lpr presure by about 5psi. If you need more detailed instructions I can take pics for you and post them.

[MORFEUS]

That would be great thanks for your help man.I pretty much do all the rest but this a first.

[MORFEUS]

I hope you didn't forget me El.

Thanks again

[Jouster]

Pictures of everything are available on AngelFAQ.com (http://www.AngelFAQ.com).

[MORFEUS]

Thanks Jouster.So from what I saw you take out the piston and the lpr body with the removal tool correct??And then you see the spring stack

[Jouster]

Nope, just the piston (Routine 16 (http://www.angelfaq.com/angel/routine16.htm)).

Jouster

[MORFEUS]

Thanks Jouster I got it (by mistake).If you dont know for sure that the shims are there you can not tell.The funny thing is that there are only two...is that normal??I will have to wait for my Angel toolkit.Anyway thanks again

[paul_mn]

I have a Custom Products regulator with a gauge that I use on my autococker. Do you think that I could just screw that on the angel and adjust it to 500psi (I have an IR3) and then set the LPR? Then I'd put the angel mini reg back on and adjust it so the angel shoots at a proper fps? I think that would work.

[molecule_of_ejam]

how would i do this on my g7 ?

[Trigga Nometry]

how would i do this on my g7 ?You mean how to set and change the LPR pressure of the G7? If so, check the manual, it has pretty good instructions on how to do so. The only thing you'll need differently is that you'll need a different LPR extraction tool than the one that comes with the WDP tool kit because the LPR piston on the G7 has a larger air flow passage (what the LPR screws into the help remove the LPR piston).

See this for the LPR tool (you'll still need the WDP tool kit gauge): http://www.angel-owners.com/showthread.php?t=45391&highlight=tool

Ken,

You've got me curious now based on your response to my question to Frazer regarding high altitude. Can you upload a drawing or a pic that shows this ASA adapter and gage connected to the air system of the marker? I want to check my regulator pressure now and I'm not sure I'm visualizing how this is all connected.

thanks.

[doodwheresmacar]

hey guys. i have an ir3 basically stock. its taken less then 15000 shots and i get first shot drop off. at first it was firing fine but after 30min of playing with it, the first shot basically was a dud. the ball wouldnt even fly out of the barel and the next shot would fire both of them (if not a ball break). but shots after were fine, like nothing is wrong. if i wait 20 sec or so, i get FSDO again. it was cold out (below 40) could the weather affect it somehow or could it be lpr? cuz i have no idea wat the problem is.
