Crazy Air hole diameters!

[Telescope Neil]

What would bigger air holes do on a greatly built rba? Almost all vapers here in the Philippines are pro at rebuilding already, since it's probably the most widely available atty here, and it's really popular. Same as mechs. But I don't get it! People here are crazy about Air holes, they say the bigger it is the better. But for me, a 1.5 mm air hole is already too big. 1.2 mm is what I find the best, but almost everyone goes for 2mm, some 2.5 or 3mm, and I also saw one guy who has multiple RBAs with 4 and 5 mm Airholes! like wth? how is that so satisfying? though they produce godly amounts of vapor, even with high PG juices. It's like looking at real nimbus clouds when they puff it out. is its point only for more vapor production?

That's exactly it. Vapor production. There's a sub culture of folks out there who drill huge air holes, build super low resistance coils, and post videos of themselves blowing enormous clouds of vapor. I don't see the point in it. But to each their own.

Then there's really no point, it's stupid. Who'd want to puff that much out in public?

No, there really is no point, for me anyway. Some folks just build these vapor machines just for show. I don't know if they vape like that all the time. I certainly have no interest in it. For me, vaping, and building RBAs, is about enjoying the flavor of the juice.

 

[Telescope Neil]

Indeed. Btw, there has to be some downside on big airholes. what could they be? less flavor or TH?

I could understand cutting a slit the length of the coil for better airflow to the coils, but not a gaping hole.

I am one that enjoys a 3/32 airhole for each coil i have set up. I get a satisfying nic delivery actually cutting down to 6mg and still getting stellar flavor without having to suffocate myself on superlong drags. 3-4 second pulls and thats it. Its relevant to your builds. When im vaping my dual coils at .5 ohms i need that airflow to be quick. But in the end its just preferance. Everyone has their own vape style. Whatever keeps you from having an analog.

most of the rba caps i have bought came with a pin hole for the air intake.. after a few toots i feel like my head is going to explode!! im with beanpusher on this one 3/32 air hole if just right i also hit stait to the lungs. i don't mouth it then lung it, thats for girls lol... j/k..

I'm currently using a 2mm hole on my Igo-L with a .6ohm coil. Hits harder than a cig...instant vapor production with awesome flavor and throat hit.

Definitely love this setup since I finally got a .6 working correctly, perfect vape for me!

Much less throathit. If they had the coils at a reasonable resistance there'd be more flavour but they tend to like them hot and sub 1ohm so it'd have less flavour and be really really warm and moist.
Most of them seem to have multiple coils so the coils that aren't in front of the ginormous airholes would be providing most of the TH, although how much TH is possible with massive airholes? I had 2x1.5mm holes in a plastic chamber and the throathit was almost non-existent (for me) with dual-coils and 24mg juice. Stopped using that tube once I missed the TH. Vapour and flavour production was nice while it lasted, but not worth it at all.

I've seen it suggested that a major factor is the humidity in the Phillippines; that vapor is produced more easily and they need to add more air to the air/vapor mix to get a satisfying vape. Either that or they do it to post one of the many green-tinted (why are they always green-tinted?) vapor-cloud videos that show nothing but a person in a room blowing huge clouds. Seems like a strange niche of vaping if that's the only reason. I have to think it's more to do with getting a satisfying vape.

I have to say that I also bore out the wick hole to 1/8 and the vent intake to 3/32 then 3/32 on the cap.. I get great flavor and throat hit at 12mg 70/30 pg/vg running at 5 ohms 2.3 wrap with 28 and 32 kanthal twisted..
