HI can someone tell me , which power plenum will fit the New wildcat MK3 , I saw pictures here with a plenum installed , which one fits it ? thanks LOU
fx wildcat MK3 power plenum question
- Thread starter jwrabbit123
- Start date
Officially none fit.
Unofficially the Dreamline plenum fits.
Riddle me that?
See the tiny 1mm gap that I have a tiny 1mm o-ring in? If one can live with that small barely visible “imperfection” then they fit.
If that 1mm gap is too much for someone’s emotional well being then they don’t fit.
No leaks.

no I saw this thread here today where this on had an external installed , so my question is the MK# the same thread as other plenums? like say dream line ? or is each block and thread different ?? seems like a universal thread would be best so to make less stock for all guns where as some tubes long some shorter , or is the MK#3 totally different then like other FX guns with Air Tubes .

OK thanks I posted this while you posted me the answer so it is sealing well ? so you installed 2 of them ???

maybe FX can chime in on it for some heavy slugs and to run lower reg pressure like you doing thanks LOU

I sent my mkiii sniper in to service, complaining of the lower than advertised power.
After 3 weeks now, they've said they are waiting on a batch of wc specific power plenums that are required to reach the advertised power level. While on one hand I am thrilled that I don't have to install it, I am disappointed they didn't ship from the factory in a configuration that meet expectations and advertised performance levels.
I would advise you to call or email fx usa support, and inquire as well.

Keith from 68. Whiskey installed one on his MKIII Wildcat in one of his videos. I don't know any more about it than that.

So if that happens - I wonder what those of us who bought them the first week (day) they were available and haven't modified the gun at all will do/have done?

Will this be an additional plenum to add to the airtube hence makes the airtube longer or will it be a different plenum inside the airtube without making it longer ?. The advertising of the WC Mk3 says “ bigger plenum” . This would mean no elongation/ add on but more space inside standard tube right ? What you are saying would mean that the Wildcat MK3 was shipped ( at least part of them) without the bigger plenum as advertised. This will make many new buyers insecure about if they bought the right version that has increased power potential . i also bought from the first badge a .22 . I hope FX will give clarity soon in this matter.

I just installed the 1.5 plenum and I warn you to get the right size oring in addition don't use the old oring unless your going to apply silicone grease, just a light coat and snug the cap down good. Keep in mind that this a a HIGH PRESSURE air tube. place everything back as you found it and buy a Tanto moderator and your good. OH yeah one more thing, adjust your regulator between 150 and 200. DONT EXCEED 200 reading on the regulator.

There’s been a lot of threads, and no answer, on whether the Mk3s are supposed to have the power plenum straight out of the box. It would seem they were, because the .25 Sniper in particular fell far short of its power claims. Wimpanzee sent his in due to low power and it came with the power plenum tube extension installed. And that’s getting the power up to the 70 fpe.
JoeKool installed two Dreamline plenum tube extensions and brought his close to 70. As he said, the Dreamline extensions do leave a gap. Ernest Rowe sells 1.2” and 2.5” extensions meant for the WC on his site. Wimpanzee’s came back with the 1.2” installed. BIgRagu installed the 2.5” and posted a thread here. With the 700mm Sniper, the two 1.2’s or the one 2.5” extends the air tube just shy of the barrel/moderator interface. Not sure how the work out on the compact...think you can only do the one 1.2”

Don't mean to hijack, but I'd like to know the pros/cons of the 1.2" vs the 2.5" plenums. I've got a couple of 2.5" units from ernest yet be installed, one for a .22 compact, and one for a .25 MK#3 compact. Is the 2.5" overkill for .22? I use a narrow mod, so clearance shouldn't be a problem. What other considerations are there?

Let me apologize and correct my post starting here with you first.
1) 1.2 plenum from 910 Airgun tuning
2) Go to The Oring store and they'll suggest a slightly harder and durable oring and of course apply silicone grease not lube, there is a difference.
3) The Tanto fits better for the length of which my air tube perturbes.
4) The manual has do not exceed 160 I believe but experimentation is what makes this airguns evolutionary. After installing a 2.5 plenum you may or may not feel comfortable going pass 160, in that case don't. Of course keep in mind your warrantee so that you do not void it.

That sounds more familiar

Normally o-rings are provided ( at least 3 pieces) with the 910 AT delivery... Newman Buck knows what O-rings he provide..
3) The Tanto fits better for the length of which my air tube perturbes.
There are many alternatives as well for that length

It would be useful in case you would mention your caliber , type and the sort of projectiles plus desired speed you are into. Then maybe these very high reg settings could make sense which I doubt anyway. Having a powerplenum and setting the reg higher than 160 makes me very curious what you are sending out of that barrel at what speed . At such high reg settings you also enter into “hammer issues” like the weight of the hammer and springpower needed to open the valve.... Tell us some more of your adventures and experiments with your WC MK3 ...

In the picture is my .30 Wildcat MK3 and I'm looking to shoot slugs with it at say 50 grains and high BC. With slugs you gotta be at least 160 to 168(Ref. FX USA Technical department). Using a chrono and adjusting hammer tension after the regulator is set is the way I was advised to do it but then there's always more than one way to skin a cat, that also was told to me by the above referenced person. I paid 1300.00 for this thing lol. I just got off a call with FX USA and this is what was communicated to me sir.

Hi Kevin, I will give you my 2 cents on PP issue you bring up. Anyone who wants to correct me please feel free to do so..
The shorter version 1.2” Power Plenum is making more sense on the WC compact as this size of PP is giving you some additional speed potential at the same reg setting bringing you in more comfortable slug or heavy pellet territory. Adding more Plenum space would make you probably like to bring the regulator pressure down and that is with a short barrel (500 mm) not always a good idea . With a short barrel you need a short burst of air pushing behind the pellet or slug that is not “ blowing” anymore when the projectile is leaving the barrel. hence shorter barrel higher regulator pressure . ( short hefty air push) The short PP version from Ernest Rowe is just giving you that extra speed for like I said some slugs and other heavier stuff to make them go at optimum speed. When you would add the large 2.5” plenum in a compact WC I believe the additional speed is minimal and the possible effect of lowering your regulator pressure is not what you want with a short barrel combined with your need for higher power.
in contrast the sniper version with its 700 mm barrel has much more tolerance to lower reg speed as the projectile is longer in the barrel hence the time of pushing air behind the projectile can be longer. This means that with a 2.5” PP you can indeed lower your reg setting nicely and still get increased speeds and better grouping and air efficiency at the same time because of the bigger plenum. Ernest has so much know how about these needed volumes for PP to make rifles work “ better” that his PP versions are close to perfection in how they do the job I believe from my own experience. So getting back to your question. I would install small size PP in compact and large version in the sniper version of the WC MKIII.
In case you are not into heavier pellets/ slug shooting I would recommend to leave the rifle untouched as it is good as it come out of the box.
However FX advertises the max power outputs of the WC MK3 considering the user will install at his own costs a Power Plenum. The best source for that is then for sure 910 Airgun Tuning . Newman Buck the manager is a very fine man who will do all possible to make you happy ! ( my personal experience as he sends me replacement Plenum without questioning or doubts when I encountered a small issue with installation. )
again this is my 2 cents and others might havea different view on the PP issue and that is fine too.
cheers
