Snowpeak No step in pressure tube Artemis P15!

Hi again.
As per Huma we need to check the step inside the pressure tube and it MUST be equal or larger as 82 mm if we want to install the Huma XL version (instruction photo from HUMA attached).

The XL version here:

I opened my Artemis P15 , removed the chinese regulator and there is NO step inside the pressure tube, I triple checked, it doesn't exist!

This means I can install the huma XL version right?

Thank you

I had my own plenum made using Huma reg. It does extend past the step and only takes a little more effort to assemble.
Never been any trouble. Mine is old, probably one of the first ones.

For what it's worth, the high pressure area can take regulator pressure, obviously, but I wouldn't do it the other way around on mine.
Maybe the new version is made thicker overall.

What did the plenum improve exactly?

Well it did the usual: bumped up speed significantly. I had tried upping the power to no prevail. After installing the plenum I got way more fpe. Something like 10 to 15 fpe more out of a previously anemic setup. Just enough to smack serious critters.

Increasing regulator pressure does very little after the max efficiency is achieved. Then it pretty much doesn't matter how much you wound the hammer and reg.
When you find that level, adding plenum size usually nets you more energy without touching anything, although one may want to search for all those loose ponies and get the accuracy.

It's been much debated if plenum saves air. What I have interpreted is that when shooting your max power level with a very small plenum, you're wasting a lot and not getting much out of it. So in that sense adding plenum volume will inevitably increase power and conserve air, albeit not to the extent to be regarded as air saving add on.
This is only my take on rather meaningless endeavor years back.
If someone has in depth info, I will stand corrected.

All the best

Thank you. I will buy and install it to see what will happen.
