I'm not quite sure I understand what you mean by "100% airflow." If you want the vapor from your e-cig then you'll have to suck on it at least a little. I don't have to put a lot of effort into vaping. In fact, it's easier than smoking a cigarette.
Basically, I want to vape differently than than everyone (I've just realized this), Instead of 5 or 10 second draws.... I want an ENTIRE LUNGFULL of vapor in 5 seconds, and I want it all to come from the E-cig, kind of like how you smoke hukah, you get a LUNGFULL in a 5 second draw....
I just chatted to firefly13 on the forums, and came to the conclusion that this is currently IMPOSSIBLE because ALL AFTERMARKET ATOMIZERS are restrictive on their own, meaning if i were to just suck on a bare cartomizer the airflow would STILL be too restrictive.
Which is Why Ive come up with this little idea:
Its a mod that would encase the entire atomizer inside a chamber, along with the e-juice and cartridge, the chamber would have an opening at the end of it. The opening would be basically just like a cartridge you can suck the vapor out of. Inside the chamber where the atomizer and cart sit, there are adjustible airholes that can increase or decrease the airflow. That way, you can basically breathe in the vapor as easy as you breathe air. That way, you can use any atomizer, and have 100% airflow if you wished (but then you'd get almost not vapor), so its adjustible, if you turn the airflow up it comes at the cost of vapor (less vapor), if you turn the airflow down you get more vapor. So If you turn the airflow up you wouldn't have to take 10 second or 5 second draws, you can take a lungfull of vapor in one go, and the whole lungfull will take like 5 seconds to pull in.

This is the only way i can think of to get more airflow out of a stock atomizer, the airholes i drew were HUGE but of course they would be very tiny in reality, and in all likelihood there would only be one of them, i just put them like that to make them easier to see and understand what I Was saying.
The only other alternative is if they made atomizers with larger air holes so the airflow was less restricted, then you wouldn't need the silly chamber thing...
