Did any of you guys try that Huma power plenum kit on a Wildcat 0.30? I’ve been interested to hear about any experiences....

Not a .30 caliber but a .25 caliber Wildcat MKII, see this thread:
https://www.airgunnation.com/topic/fx-huma-power-plenums-bullpup-power-dreampup-22-wildcat-mkii-25/
My tune...
Only 130 bar (Huma regulator), JSB 33.95 grain 885 fps / 59.05 fpe, 56 shots per fill (7 eight round magazines)

Awesome tuning JoeKool !
Do you know if the Dreamline Power Plenum from FX can be used on a the Streamline too? I assume that the air tube of the DL and SL have the same diameter/same thread.
I'm not to keen on using the internal power plenum from Huma on my SL because it will obviously reduce the volume of the unregulated portion of the air tube.
My goal is to increase the shot count for the same level of accuracy as what I'v got today when shooting the JSB 18gr at ~915 fps with the Huma reg set at 125 bar.

Thank you Stephfx,
The DL plenum should fit the Streamline block and air cylinder. Your tuning plans for your Streamline sound logical and will probably work out great.
Happy air gunning & good luck!

Was not expecting such a quick response JoeKool 
Thank you very much !
I'll go ahead and order the DL power plenum then. Hopefully it will allow me to shoot the 18gr at a lower reg pressure for the same speed, which gives me the accuracy that I want. Exciting ! LOL

Bad news for the Streamline owners... Krale, one of the biggest resellers in Western Europe, have informed me that the Dreamline Power Plenum will not fit the SL, despite the fact that the tube diameter and thread pitch are the same on both models. Reason I was given: the length of the threaded section is different...

Update re/ installation on SL: just got a confirmation from FX : it can be done ! See this post: https://www.airgunnation.com/topic/fx-dreamline-power-plenum-installation-on-streamline/#post-667107

Hi, thanks for the info. Is that a 600mm barrel or bigger? I just bought a MkIII sniper which has a 700mm and I'm trying to figure out how much room I have to work with between the end of the tank and the moderator. Do you know of any reason why all of what you did won't work on a MkIII? I know FX says that they have added plenum space, but I'm curious if adding more will improve things more. Also, was thinking of adding a tank extension for more cc or air in the tank.

Very welcome sir!
Thx Bowhunter73, this thread is old but I have refined the .22 DreamPup’s tune and power mods to perfection. She’s one of my best .22 PCP’s hands down. Amazing with 23 grain NSA slugs, .22 cal 25.39g redesigned, 18.13g JSB’s, and H&N 17.90g Sniper Magnums. Now equipped with the 600mm STX Superior Standard barrel/liner. Just about anything of quality that I load, this bull-pup can shoot! What a lead gut!!
