Airflow on Vivi Nova

[Been_Verbed]

Been using an igo for sometime now, which I have drilled a 1.6mm [1/16"] airhole into, and now trying to adjust to the vivi nova airflow. The only reason I'm using the vivi nova is for the convenience of the tank and it taste pretty good with ss mesh. I wanted to know if anyone has drilled the airflow for the vivi nova, and if so to what size and with what? It seems the airflow enters through those two little holes and travels through the center post from the bottom where the slots are cut. Tried searching for a thread, but the proxy was changed making it difficult to find specifics. If anyone has experience with this or knows of a thread they have found, a response would be much appreciated.

I have found an old thread regarding the airflow, but doesn't explain whether it was drilled through the center post or not. I imagine it would increase the airflow either way, but I want to know what size dill bit someone might have used and how did they get the burs out of after drilling? I don't want to make a mistake and render my nova useless, any suggestions?

Never mind. Found a video that shows the airflow restricted at the bottom 510 connection as well as the atomizer head.
Any idea how to delete a thread?

Don't delete the thread. Post a link to the video you found.

There is 2 holes in the bottom above the threads and to holes in the center post up to the coil itself. I actually think that they are a little airy, I prefer a tighter draw, but then again I havent ever used SS in mine.

BTW, Can you post some pics of your nova with SS mesh wicking. I would really like to try this just not sure how. Would really appreciate some help on this.

I found the video on youtube about "Improving vivi nova airflow".

There are holes at the bottom, which I did not drill, but the atomizer head has a restrictive draw due to the size [ 2 inlets at the bottom and one going to the coil]. I just drilled a 1/16" hole in the bottom of an atomizer head, removing this nipple and the airflow is so much better. Used a hollow wick that fit in the stock head, and trimmed it to fit in the tank.

The wire shown is 33 AWG Kanthal twisted over three times at the end to prevent hot legs. When you dry burn, look closely and you'll notice the coil stops glowing where the wires are twisted. Make sure these wires are twisted tight and trim the loops before wrapping the coil. I left 3/4" in the middle to wrap my coil with a 3/2 wrap giving me 1.8 ohms.

Sorry, but I have a number of questions;

I recently learned that saying "Vivi Nova" is not enough, since this only describes a style that is produced by several different companies. Which company is your Vivi from?

I know it is hard to describe in words a physical object, and I am not clear what the various inlets are that you are talking about. But, once some folks get them in stock, and I can get one in my hands, it may be clear.

I imagine you have to be very careful to keep the fluid level below the hole you made. If you consider this to be when the unit is on its side, that is probably a significant reduction of the capacity.

Regarding your stainless steel wick. I was very surprised to see your picture. It looks like you would have to tip your unit to a nearly horizontal position to whet your wick. I have never played with stainless wick, but I wonder if it is possible to make it significantly longer, and bend it so that it is more like a regular wick, in terms of the area it covers in the tank.

The holes in the center post are inside of the column. there is a metal piece that you can push out that has 2 small holes in it. So you wouldnt have to worry about over filling.

not sure if that helps you to visualize, but like around the second X from the top there is 2 small air holes on the inside

There are 2 holes above the threads at the bottom of the base where the 510 connection attaches to the device. The air travels through the center column, from these two holes to the atomizer head [ 2nd Picture ] , where there is a small inlet to the coil [ 1st picture ]. The bottom of the atomizer head [ 1st picture ] restricted the airflow to the coil. This piece is the small positive connection to the center post that is separated by the rubber grommet [ 2nd picture ]. I drilled the bottom of the atomizer head to remove that nipple, which allowed more air through, providing a less restrictive draw.

The tank was less than half full, which works fine with the ss mesh. The natural tilt to the device provides enough of an angle to moisten the wick, but when the liquid gets to less than 1 ml, you have to tip the device to wet the wick. If you stand your device in the upright position, there is a possibility the wick will not have enough liquid to produce a satisfying vape. I use this Nova when outside the house, so its usually in my pocket, not attached to the device, which keeps the wick moist.

There are tutorials on making a curved wick, but I find the short wick takes only a sec to moisten with a quick tip on a low tank. The natural tilt of the device when vaping, provides enough of angle to supply the wick with liquid. I never hold my device completely vertical when vaping, feels awkward.

VERY NICELY DONE!!!

Interesting thread. I have two different models of vivi novas. One has the holes (2) on the 510 connector, the other one has (1) hole in the side of the lower "plate" where the tank screws too.

I get too much air from the vivi nova that has the hole in the side. I think it's too large. I like the amount of airflow from the vivi nova that has the (2) holes in the base.



I should add that it also depends on the juice. I have some Sub Zero from Pink Spot and it vapes and has good taste in the vivi nova that has the (1) I really don't like... Go figure...

I just read the holes in the 510 connector is the 2.5 version. Hole in the base 1.0. I got ripped... I like the 2.5 much more. Guess I'll have to email the company I purchased them from.
