I prefer the small stock Griffin air hole more than the large one. Sadly, the small air hole is too tight (even puffed light) & it hits one spot overly hot on the wick. The large hole caps are too drafty for munless huffed hard. I took my large air hole griffin replacement cap & DID(pun intended) what needed to be done, to bring my idea to life...
I do not know the original air hole sizes, but the bit I used is a tad less than 1mm. I assume the two small holes I drilled actually allow more air in, as their total combined open area is likely more than the single large air holes open area. The two holes draw vapor loosely like the bigger air hole, but the air is not a single (little to no draw resistance) draft, aimed @ one spot one the wick. The new intake(s) still vortex air into the chamber with a venturi-like pressure effect that adds draw resistance?, I suppose as it spreads the air evenly along & inline with the vertical wick(not a single spot). It is new to mE, but I like it.
First impressions: More flavor & not too tight nor too loose, just right on the draw with even wick coverage.
I would have liked to do three 0.5-0.65 size holes. Maybe next time
A while back I turned a spitfire into a horizontal genny style atty. Air from the original inlet hole, which is underneath the coil, was insufficient and produced a low quality vape. I reworked the top chamber and used two cut pieces of 14g (?) hypo tubing, to direct airflow to the center of both sides of the ss mesh and coil.
This setup of 3mm of bamboo in a 4mm ss wick had unbelievable vapor production that was completely unvapable before the change in airflow dynamics. Afterwards fantastic.

Mister E nice production on your post.... It would be interesting to see how the vape swirls in the chamber with different hole configurations. Not sure in the plastic would hold or melt, but it would be cool.
------------------------------
EDIT: The observation I wanted to share with the set up in the post above was that the creation of the two holes in the side of the vape chamber alone did not really improve vape quality. With the hypo tube creating direct "jets" on the coils it change the set up from zero to hero.
[not work/EWW]I was going to do just that, but like you say plastic would melt. I then got to thinking
, what happens inside is deep mystery to MISTer E, so what about what leaves the tip?
The main reason I'm exploring a larger air hole is because I'm helping a friend with his and he keeps complaining that he's getting too much throat hit (2ohm coil, even @ around 3.2v he still says it's too harsh). He still smokes and he says it's way stronger than his cigs (ultra lights) and that it's choking him even with small 1-2 second pulls on the Cobra (he also mentioned it "burning"/being "hot" although I'm not sure if he's using the terminology correctly as he should be around 6 watts or so meaning it shouldn't be hot?).
Like I said before, it's a 4-5 wrap @ 2-2.3ohms and regardless of the volts he says its too strong. There are no hot spots to my knowledge (pic of the coil below). He's using Heavenly Tobacco juice (RY4 variant) from Heather's Heavenly Vapes at a 30VG/70PG ratio. It's a 500 mesh wrapped tight (no center channel) fully oxidized (maybe even too much).
Having said all of the above, what could I do to lessen the harshness (he wants to feel the throat hit, like he would a cig, just not overwhelming/choking)? Different juice? More wraps on the coil/higher ohms? Or just go ahead and try the 1/16th hole (I've already bought the drill bit in case we end up going that route).
Thanks for the advice in advance.
Great vid zeesmoker, MISTeragrees too tight a draw can be a pain in the jaw & the law must be drilled into'em if need be
Maconi the spacing between wraps was much wider on your first image. Your later image has tighter wraps. A coil has neat properties. Widely spaced coils are more independent of each other & get almost all their heat individually & slowly from largely the electricity. Tightly wrapped coils bump up the heat & heat up quicker. One wind heats up & the next one steals a bit from the already lit one, as it get lit. The outer coil ends are always the coolest on tight spaced coils because they lack a snuggle partner on the outer side.
