Huma fx slug power tune kit

[Turbo911]

I,m new to the fx brand and have a ,25 impact m3 for which i have ordered a Huma slug power kit and a Huma v2 transfer port has anyone any experience and or feedback of this set up as from doing research on the forum the similar fx tune slug kit seems to have differing set ups such as don’t install the rubber ball or use a softer spring to get the best out of it, All to me seems a bit confusing i should mention I’m running a slug liner barrel and in standard form getting around 985 fps and 72ft,lbs power with 33.5g jab knockout slugs was hopin to get to around 1030fps,

Thanks

I'm thinking the smaller brass hammer will work. I ended up using the stock springs.in my gun they had more consistent shot strings. You'll need to have your reg over 160. You'll hear if your hammer hits too hard .

Hi I have the m3 600mm. I am shooting .30cal slugs at 47.5gr and 54.7gr. I was think of going with the huma kit too. I think it's great I am still doing my research on it first. i decided to go with the carbon fiber liner, the .30cal 600mm superior heavy barrel, and the carbon fiber barrel tuner until I decide what will be best for me

Hope this helps

I’ve seen that video and its not to inspiring hence why I’m trying to get more information and as wr250 says he used the stock springs, Which is mentioned on other threads on AGN finding it a tad confusing if anyone can chime in and offer more advice??

I have the mk2 25 and I installed the kit as shown with the ball . The thing that I noticed was that the regulator had to be turned down to 110bar and I’m not even close to being maxed out on the hammer spring. I have had the best luck with the nsa 36.2 slugs very easy to tune for and I am getting 940-950fps on max but I shoot mainly on min power @870 with outstanding results as well as max but with more shots between fills. Good luck

This is why i,m finding it confusing, i,m getting around the same speed as you with a very slightly lighter slug so am i right in thinking the power kit doesn’t work ?, And on other threads where results have been posted there all pretty much running higher reg pressure to get more power/faster speeds ??

I tried to understand that too about not using to ball and new spring. I think the reason is the new spring is not as strong as the stock spring. I have watched a few videos on the topic and that's what they say. The ones running the 600mm barrels use the stock spring in order to have Shortier air burst, so it don't effect the slugs when firing. As for the new huma spring people running 700mm, and up barrels would see better gains. the new spring and ball with longer barrels need more air for slugs go thou the barrel of a 700mm or 800mm barrel. The new spring is lighter and would keep more air release for those type of barrels. I guess the longer air burst time without messing with the reg settings, and not putting to much pressure on the gun. I hope help a little.

Thanks and yeah i see it pretry much as you say I’m running 700mm barrel (sniper) Huma must of sold loads of these kits but proper info seems thin on the ground think it might be a try it and see as a learning process or maybe i will just start with the probe and record my findings…

I think with power kit, you also need to go "power" reg pressures, i dont think these power kits are made to shoot 90 - 100 - 110 BAR, probably more like 130 -140 - 150 BAR

awesowe glad to hear that! 


No you don't need it. It came out with MK2 impacts, but if you install it in the M3 it actually slows it down. Thats what the Ryan at utah airguns told me when I asked about the power kit.

 

[Impact_m3.]

I think you should try the Fx M3 Power block/Power Plenum Upgrade Kit I think that might solve it all but it's in pre-order at the moment. I have been researching it and it look great if you don't mind installing it. Once I get my next paid check it's the first thing I am ordering.

Thanks for the reply’s, think i will go down the route of trying this and trying that and making the necessary small adjustments to see what works for me rather than just fit the Huma kit as far to much uncertainty on if it works as described i can always reverse back to my original set up…

No problem I am happy I could be of some help to you, good shooting and have fun with it.

From what I've read the slug power kit from fx and pin probe worked better on the mk2 and alot of people are running the huma spring and v2 port on mk3 at like 150 bar on the second reg or a tad higher also read to open the new valve control up to the six line which isn't there but like a turn and a half to two turns past the 4 line

I have an m3 700mm in 22 cal and currently set 160 bar on 2nd reg and shooting 31.2gr NSA slug right now at 1010fps and making shots out to 200-250 yards with ease (with weather meter help). You will have to install the whole huma kits except the rubber ball and use the smaller brass hammer if you want to do below 160bar. Heavier hammer is for 175 bar and above. So if you do that set up you should get at least 1045fps at your max but need to be 95-97% of max to be consistence and reliable and I chose 97% because I have 700mm barrel. So whatever speed you decide to shoot just do that math. For example, I want to shoot 31.2 grain at 980fps then I will maxed everything at around (980/.97) 1010fps then tune it down via micro adjustment. If you do that you should see a great result. And of course, every gun is a little different and that needs a little more work via front valve adjustment. Then do a five shot group on paper with only valve adjustment (1/8) of a turn to find the best group then stick with it.
