Airflow questions on my reo n rba ... Advice

[flexsr]

Hey guys,

I finally got my second rba for my second reo - yay !!! Now i can experiment with airflow on one of the caps. I want the ability to go own to .7, .8, .9 ohm on my reo (im sure in a month ill want to go to .3,.4,.5 ohm lol).

Anyways, i would like to make the airhole slightly bigger than stock - my understanding is that it will increase vapor production a little bit and cool the vape a little. (Correct me if im wrong)

I know to go very slow as a small change will produce big results.

My question is should i enlarge the airhole that is in front of the coil or make another airhole in a different part of the top cap. Will another airhole give a good cross "breeze" so to speak or should i just concentrate on the airhole that is already there and enlarge it as its right in front of the coil -



Second question which is actually directly opposite of the above - sometimes i really like a really dense vape. Tough to explain except the vapor feels very dense - i have an old prodigy around and once in awhile ill whip it out when i want to drip and ill use 6 volts with 2-3 ohm atty and it produces some nice thick dense vapor - if i made a coil that was 2-3 ohms and on my reo vv reo volt and crank it up to 5.5 volts can i reproduce this denseness ya think if i used my other top cap that has a stock airhole.

Lots of airflow means light vapor ? True or no ?

So littke to no airflow will produce heavy dense vapor ? True or no ?

So the only way to get that denseness is to have as least possible airflow ?

maybe alot has to do with the e juice i was using. i imagine that makes a big difference. I didn't realize I started a similar thread before. I am trying to delete thread but I couldn't figure out how. Edit will only allow me to delete the contents not the title. oh well. I do want to know on the cross airflow though versus a big hole by the coil. curious on opinions on that.

It's balance between ohm, air flow and chamber size. Cloud chasers need low ohm and big air.

If you use an ohm calculator you can see the comparison of different voltages and ohms. Online Conversion - Ohm's Law Calculator

6v at 2ohms = 18 watts
6v at 3 ohms = 12 watts
12 watts at 5.5v = 2.5 ohms
18 watts at 5.5v = 1.6 ohms

Too little air flow will also limit vapor production. Wrap a 1.6 to 2 ohm coil, put a piece of tape over the air hole and using a pin slow enlarge the hole to see if you can find the sweet spot you want.

using standard drill bits the next size up would 1/16 if want go in between stock and 1/16 you need use a #54 drill bit.

Oh and don't forget drip tips can also control air flow. At small sizes of air hole in the RBA it isn't noticed but as you increase air flow in the RBA with larger holes and multiple holes you have to make sure that the opening in the drip tip is not limiting airflow. I found some of my drip tips do limit airflow on my Cyclone with AFC cap.

To test this suck on just the drip tip, then on the drip tip when installed. If flow is reduced when installed then the air hole in the RBA is limiting airflow. If airflow is not reduced then the drip is limiting airflow or is exactly equal to the RBAs air hole.

awesome. thank you.. i will experiment with one of the caps. perfect..

last thing. the coil doesn't have to be centered over the juice hole on the bottom of the deck, does it?

coil should be centered in the airhole that's drilled in the end cap

Most go up to 1/16 air hole then you have madmen like Z who have gone wild with dual 1/8 holes.

oh... I didn't know that about the drip tips...neat...i will try experiment

Placement to the air hole is important for flavor. Placement in relation to the drain hole does nothing, just make sure your wick does not block drainage in the squonk hole

thanks for the confirmation on the juice hole.

last thing i promise I posted this on another thread- i guess Ill just wait to see if someone responds there....but last night I saw a video of a rda/rba that has adjustable airflow size holes on the side. Thought that was neat idea.as it was just an outer ring that twists.

I wonder if a reo compatible rda/rba has this adjustment feature. that would be neat....Im sure it will come in time.

thanks for the quick help....

Rob is planning to make rings for the RM2 and others have made rings from copper tubing.

I run a Cyclone with Air Flow control top or AFC for short. but it will not fit a standard Reo, you need one with a milled catch cup. Listed on his site as Low Profile Grand

Ahhhhhhh. Cool

I behind the trends a little.

Adj. airflow wld rock.
