tight draw vs stiff draw ?

[otis45410]

thinking about drilling the air hole out on my noble 1. I have a zenesis standard and love the open draw, however they are both VERY different in the way the vape. I guess i was wondering if someone could enlighten me as to the pros/cons of tight or stiff draw. Thanks

To me, it all relates to how much energy is in the recipe. You want to have the right amount of air in that recipe too. I stick with a pretty standard 1.1-1.2mm hole until I get below 0.8Ω. Then I need more air. A tighter draw will generally give you more TH, and looser more clouds. Other than that, I think its just preference of how it feels and some about variations in atty chambers.

thats kind of my opinion too. the reason i was considering it is the noble1 is a HOT vape. i havent been getting the best throat hit, but it might just be the juice or coil. maybe i will hold off. i have experienced the sorrow of drilling too big before. the weird thing is that the zen seems to have more throat hit with a bigger draw. it might just be the larger chamber/taller wick or any number of variations.

Yeah, TH in a horizontal coil (dripper) can vary alot depending on whether the air goes over or under the coil. But in a Genny style . . . . . coil height? Distance from air hole? I know zen says he's got the mushroom cap air flow thing . . . . . .

But in a Genny style . . . . . coil height?

almost the same problem but at a different angle. some wicks are close to the airhole and others far away. i have seem airholes in the center of the coil area and some cheap ones below it. a smaller airhole also contributes to a venturi effect where the vacuum of the draw causes the air to rush into the chamber (and over the wick) faster and harder

while not all of them many of the better attys and genis have been tuned, the shape/size of the bell the airhole and wick placement.
a couple examples of this are the spheroid where they worked on the shape of the intake bell for months. and things like the foggatti where the only space inside the cap is just enough room for the wick and center post.

the zap is wide open draw but the cap is fat and short causing the vapor to swirl and build up.

the cobra is a small tight draw but a thin long cap

both can put out storm clouds if built correctly.

i would say for the zap either try some different wicks or lower the voltage, do a prewarming button press and make sure its tilted while the airhole is directly on the wick to lessen the TH.


if your going to drill an atty take it slow. like.1 mm at a time and use it for a day or at least several hours with a good working wick. the draw is subjective and a slight tuning of the air hole can make a killer atty into a wicked one. besides tuning sometimes the draw is just what the creator thought worked best and not subject to design rules.

cool, thanks a lot for the detailed info. i got the noble working better by switching the wick/ coil. the zen hits like a train no matter what.
