Huma Air High Flow Dual Hole Transfer Port Installation 

After watching all the video’s on the disassembly and assembly of the FX Impact I can see why this Airgun is expensive , it requires a lot of labor and precision to put it together ! You do a good job of explaining so most of us can feel comfortable in upgrading & maintaining our Impacts , I subscribed , thanks for all you do !

Another superb video keep up the great work and thank you for the instructional work and knowledge you give us

Great video I have done the same to mine, with great results, huma are going to a modded tp soon so people won't have to mod their own 👍👍

Nice video! Thanks man

Great stuff

Very good info, thank you!

Thanks 👍🏻👍🏻

Amazing👍🏼👍🏼I want🤙🏽🤙🏽

Great video, thanks. So the transfer port only needs to be hand tight?

I install the Huma regulator and the dual hole transfer port and pellet probe of huma and i shoot with my impact .30 the nielsen slugs 49.5 grains at 1070fps very easy !!

bij een .30 dreamline met cilinder ,heb ik ook de huma reg met de 30 cc plenum en fx plenum(47 cc extra) plus de dual flow ,en met de reg op100 bar en transfer port op 17 .22 en hamer spring druk lager gezet heb ik nu 50 schoten (tot reg druk)die de 22lr swinger(caldwell) op 50 meter met grote kracht zeker omleggen ,waar die met een normale magnum springer alleen klinken ,alleen de hatsan carnivore 135 .30 kan het ook maar niet zo gemakkelijk wegens de enorme zuiger en veer(krijg daar zelfs nog een .299 79 grain slug uit ) . trouwens de fx fabriek zegt/ adviseert ,de snelheid verhogen kan maar beter is om meer schoten na te streven op lagere reg druk.want voor de pellets is meestal 800 tot 850fps het best wegens de precise of nog lager ,2 bij sommige kalibers ,de kleinere dan .30 helpt het ook om de orginele probe doorgang te vergroten.want anders helpt de dual flow niet veel, je kan de probe en dual poort vooraf buiten de montage bekijken door de probe in de dual flow te steken en zie je rvs van de probe dat zit in de weg .mvg peter

Great info! Does changing the transfer port reduce your shot count?

Did you have a small gap (or small amount of play) in the area of the first oring you removed between the barrel and transfer port? I do on my stock .30 arrangement

Hi , since there is some air restriction with Factory FX Transfer port , when we use the Huma one do we get more power WITHOUT decreasing total shots count ? thank you so much

Nice video! Was there a gap where the brass meets the steel. My O ring seemed to small. It has to much play in it

What was your reg pressure on the second test, also you didnt re-install the small inner O ring.

Hi, if I put this part on and slug probe on, what FPS will I get please?

Congratulations on the Video, very educational! I need your help with a tip! I have an FX Impact X, I installed an internal power plenum and I have it in caliber .22 .25 and .30 in length 700 ... I am interested in buying this accessory from Huma ... here comes the doubt: considering that I already have power plenum Do I tend to think that the greatest benefit should be in buying this accessory, looking to give it all the power to move the largest caliber? My favorite caliber is 22 but I think that any benefit of installing this port and probe is marginal since it would be solved with the Power Plenum ... right? between .25 and .30 which do you think should receive this accessory (considering the ballistic curve, weight and everything that affects the shot in these calibers) I hope you help me since I have in the HUMA shopping cart this product to waiting to lean on what caliber, greetings

The pellet probe is a big part of this system in fact this part is is useless without it. It was not clear that this was needed, it’s not stated on the HUMA website or your video that a probe was needed! I’ve put the transfer port on, is my rifle waisting air by having a larger hole? Why would anyone sell something that’s incomplete & there’s no word when if ever they will make the additional probe! Thanks...

So this works for FX Wildcat Mk2? EDIT: NOTE! This transfer port does NOT fit FX Wildcat 2. It is the same diameter but longer and has a sort of flange sticking out at the breach end. The Wildcat 2 port is slightly shorter and is flat at the breach end.

Hey guys" got a question or two! I got a FX Crown, I watched this video 10x or more and had no problem installing the Transfer Port but got no real bump up in speed! Do I have to have the Pellet probe to complete the system? He doesn't cover that. I bought the transfer port without the probe...

I have the Slug power kit installed on my Impact... will it be a good match with / make sense to install the Dual Air Flow Transfer port ? Would greatly appreciate your advice.

What besides adding fps does this improve? Does adding this cause more air from your tank to be used?

Hi Airbuks, hope you're keeping well and safe. I need your advice and help please. I've now followed (since one of our earlier conversations) and installed a Huma dual transfer port on my .22 FX Impact MkII with power plenum and 700mm Superior STX barrel. However, my velocity as measured before (single port) and after (dual port) remain identical which means the addition of a Huma 2-port has not helped increase velocity! My setup is 17.2mm on the power wheel for max setting, reg. pressure of 115bars and 4th line on the airflow valve. Could you please give me some idea as to what to try by way of power wheel and reg. pressure adjustments? At present, both 1-port and 2-port settings give identical 900ft/s with H&N 25 grain slugs and I'm hoping to find the optimum setting (so without wasting air) to increase my velocity from 900 to say 950ft/s to improve the accuracy of H&N slugs. Many thanks for your help. Take care.

Hi, did you do this upgrade for shooting pellets or only to shoot slugs. I changed mine for slugs in my dreamline but i cannot get the slugs to group so I'm going back to pellets. Is it ok to leave this TP and probe in for pellets

Hi please I need a link to get the tool to take the inner O ring out

Did you also change the pellet probes,?

Did the pellet prob come with them? Was it a kit?

Great video. I god your transfer port and installed it on my FX crown mki2and the pin probe. My problem is I now cannot get my barrel returned to the key position. It needs to return a millimetre or so more but I cannot see what is causing the barrel to key in. Any help would be appreciated appreciate d

Is there not an internal o-ring on the huma port?

I think my dual-hole transfer port is too large (the dual-hole) because my slugs stuck/bump in the hole so many times now, i even change the huma slug pin, pellets pin, and slugs power kits matt dubber edition, and even change the magzin all same result and even with single loading... Dont know what to do anymore

hi.can we use dual flow port for pellets?is the accuracy same?please reply.

Dumb question here but couldn't you just use the existing hole in the transfer port as a guide and drill through the other side 180degrees out?.

Absolutely useless But thank you for your video I got it it did nothing actually made accuracy so bad

15-80 fps gain that's all🤐🤔

For 10-20fps more? I don't think it's worth the upgrade or the hassle..Jmo! You can get more fps without the modifications. There is a video from 101 airguns or 901 that shows how to adjust the fps just by adjusting the regulator and hammer spring.

DO NOT BUY HUMA V2 TRANSFERPORT! Its not working. I install it on my Maverick .25 and the speed drops!!! You will pend 50 euro for noting!

This part does nothing... Totally useless and a waste of money. I installed it and the power is exactly the same as it was before.
