fx impact power plenum 600mm 22 cal issue

[bfb444]

hi

i have fx impact power plenum 600mm 22 cal

i set the regulator 130 bar ,the front powr adjuster 4 line and the rear power adjuster on MAX , JSB Match Diabolo Exact Jumbo Heavy .22 Cal, 18.13 Grains

what is the expected speed?

because my fx only reach 935 fps is it normal?

 

[Yo]

Looks like you need a more stout spring to me. Yo!

 

[cahil_2]

YO is right. I had the same problem, so I put the original spring back in and got more power.

If your looking for higher speeds, our techs suggest with the Power Plenum, you need to take the reg Down to 125Bar, and increase tension with the hammer spring tension screw

labas

Aš turiu fx smūgio galios plenerą 600mm 22 cal

Aš nustatiau reguliatorių 130 barų, priekinį „Powr“ reguliavimo 4 eilutę ir galinį galios reguliatorių ant „MAX“, „JSB Match Diabolo Exact Jumbo Heavy .22 Cal“, 18.13 grūdai

koks numatomas greitis?

nes mano fx siekia tik 935 fps ar tai normalu?

Jei ieškote didesnio greičio, mūsų specialistai pataria, kad jums reikės pasukti reguliatoriaus slėgį iki 145 Bar ir sureguliuoti plaktuko spyruoklės reguliavimo varžtą, kuris yra atskirai nuo rankenėlės.

Sounds funny!

Do you really have specialists?

In my opinion your professionals are very weak if you share such advice!

my buddy just had his knew impact over his reg was at 80 bar 3 1/2 lines on the valve max on power wheel factory setting and was shooting 900 fps very accurate most quiet gun iv ever herd 18 gr jsb also

That FIVE BAR difference PROBABLY isn't gonna work. But I'm not an FX expert tech. Yo!

if i set the reg 115 bar and shot jsb 18.1 what’s the expected speed?

Have you tried increasing the hammer spring adjustment screw? There's a balance between hammer spring tension and reg pressure - you need enough spring tension to open the valve but not too much - watch this:

i take the reg down and increase the hummer spring tension speed is decreased 

if i set up my gun like the below setting what’s the expected speed??????

Earnest must be on vacation... Yo!

 

[ackuric]

Decrease regulator pressure 5 bar at a time with hammer preload at max until you see fps decrease then go back up 5 bar

and/or

Increase hammer strike via: higher rated spring or longer spring with same rating. (as suggested maybe original is stronger? Idk) or add more weight

 

[stoti]

First thing to do would be use a 1.5mm Allen key and max out your hammer spring pre load so the power wheel will barely turn when on max. Then open your valve adjuster all the way. Not on 4 lines, open it as far as it will open. Won’t hurt anything. Set your regulator to about 120 or 125 bar and see what velocity you get. You should have plenty of hammer and hammer spring to use your gun on 120, 125 or 130bar. You can pick up quite a few fps with the valve fully opened and the hammer spring maxed. After that you can tune in your gun by decreasing the HS pre load, backing off the regulator or turning the valve to 3-4 lines. Try it and see what velocity you get.

Sorry, Ackuric and I must have been posting at the same time.

935 fps is pretty fast. So idk what the issues is. I was thinking you had leaking or problem install the PP. Do you really need 1000 fps with pellets? From your set up, there doesnt seem to be a issue. It seem you just want more power. You need to port your transfer port bigger, and also port your pellet probe bigger. It will allow more air to pass through. This will give you more power. Also add more reg pressure. Maybe go 140 bar or even 150 bar. And max out your hammer tenson with the small Allen screw

just i want to know 130 bar reg what’s the speed to compear it with my gun ?

 

[Yo]

Is that a good thing to CRANK things ALL THE WAY and leave things MAXED OUT Like that? Wouldn't the hammer spring eventually take a set? Yo!

No, hammer spring is not under tension unless the gun is cocked!

 

[Yo]

What I meant specifically was while the hammer spring preload is MAXED that power wheel is ALREADY HARD to turn AND CRANKED to the MAX. Yo!

Watch the video above and test for yourself! EVERYONE'S gun is different and NO ONE is going to be able to give you an accurate answer. The only way to know is to tune like the video suggests and find out for yourself.

My MK 2 power plenum will shoot the 18 grain pellets 1080 fps at 115 bar. Not useful for a darn thing that fast. I can imagine 130 bar being just as useless for 18 grain pellets.
