Why would the Aspire BVC coil produce more vapor or flavor than their BDC coil?

[Traijan]

Since discussions of how the BVC coil from Aspire supposedly works better all around (i.e. better flavor, better vapor production and last longer) I tried it. I honestly can't say that I noticed any better or stronger flavor, not any more vapor production and well... I can often get 60ml of juice or more through my Nautilus tank with the BDC coil so I've not yet vaped 60ml through the BVC so far so can't tell if it's going to last longer or not.

However, after cutting apart an old BDC and BVC coil I'm looking at it and trying to figure out how in the world it could possibly change or enhance the flavor and or vapor production. But even without cutting them apart all one needs to do is look into the tiny hole to see that the BDC coil has a very bottom coil and then another coil up near the top of the filling material where as the BVC the coil is quite low set below the top of the filling material. So, I really don't see how a single vertical coil is going to produce enhanced flavor or more vapor cloud than having two separate coils that are both surrounded by the filling material to keep them saturated.

I would however, understand if the single vertical coil were to stretch from the bottom of the coil head to the top of the filling material but then that might be so many coil wrap arounds that it would be some ridiculous resistance level that is unusable by most people.

So, looking at it logically (perhaps even facts if somebody has some), how is it possible (remember, logically or factually, since taste is so subjective) that a single vertical coil can produce enhanced flavor and vapor production?

I'm honestly just sort of feeling that it's less expensive for Aspire to produce the BVC than the dual coils in a coil head and that perhaps they didn't find the flavor enhancement or vapor production worth the expense of a dual coil system so they created the BVC.

It seems pretty evenly split on people that I've read from or watched video reviews with one side saying, "no difference" and the other side saying "world of difference in flavor if not both flavor and vapor production" although of the videos I've seen it seems that the vapor production of both coils looks to be so close to the same that it might be impossible to see if one produces more vapor than the other. Of course that could be from biased reviewers who don't want the BVC to be known as better and as such take smaller hits to keep the vapor production to make it look similar to the BDC vapor production or they could be doing it honestly too.

Is there any way to factually test flavor enhancement and or vapor production in a home environment to "really" test the difference between the BDC and BVC?

Don't get me wrong, I think either of these coils works great in my Nautilus, but they both seem to work the same to me. One no better than the other with regards to the flavor and vapor production.

I can only speak from my own personal experience.
Vertical builds with wicking around the coil will give you better flavor and last longer. I have experienced this not only with the BVC coil but also with my Kayfun and Russian. I used the BDC coils and wasn't happy with the flavor or longevity of the coil. Since trying the BVC I haven't touched my other tanks.
I have had only 1 bad coil to this point and I have been using the BVC on 4 different tanks. I also think the ceramic wick has something to do with the longevity of the new coil. I have tried the same juice on the Mega, Russian, and Nautilus, and the BVC stands out for me.
Taste is subjective it varies from person to person.
I have been stocking up and have enough to last me over a yr. They are inexpensive and I don't bother recycling them.
That's my view. If your getting that much life out the BDC then run with it.

I think flavour perception is part physics and part state of mind

After I ve cleaned out a tank and re coiled I know that for 2 or 3 three tanks the flavour will be bang on before it starts to diminish ( physics )

At the times when i used to enjoy a smoke say first thing in the morning, after eating and after certain activities, my vape seems more flavourful ( state of mind )

As to your original question whether a bdc or bvc should produce a better flavour, I haven t a clue seeing as I m quite happy using the original bcc, sorry

There is a major difference in the newer BVCs Aspire coils and what they are turning out
look for youself
at the bvc contact pin. ...There you will find (2) two holes in the pin that
allows an airy VORTEX to pass ALL around the vertical coil.
Therefore the entire condensation seeping into the tank area is fully bathed
by the vortex and heats e-liquid as it is suppose to do.

Tanks need air... coils need air to heat the e-liquid properly...
Check this vs those heads (coils) where they've built their coils with a single little air hole.
It doesn't matter how great any coil is suppose to be. If you only vape from a small contact pin hole in the bottom.
No tank can properly share a true vape when the coil(S) are only being hit by
a straight line of air coming from the bottom... because when the air hits the coil(s) it splits and
a major portion of the e-liquid is left setting on the top side of the coil.. because NO air ever hit it.

I'm not sure if I understand you correctly but I looked at both the BVC coil as well as the BDC coil and they both have two holes in the bottom peg on the coil so I'm not sure which two holes that you are referring to the only physical difference that I can see between these two coils might be that the BVC coil has larger openings where the juice goes into the wicking material other than that the two that I examined looked identical as far as the coil body goes. Plus I'm not positive that the 4 holes surrounding the coil are bigger really as much as I was looking at a fairly new BVC coil and a BDC coil that I've soaked in vodka many times now, so it might be an optical illusion in that I can see the "white" of the wick on the new BVC but only the "black" of the wick on the old used BDC coil that I examined together.

Maybe there are some other holes that you are referring to on the coil heads post that I'm just not seeing, but on my two coils that I examined, they have a hole (2) that basically simply runs through the center of the coil heads bottom pin, as far as I can see they are nearly identical bodies (obviously the "guts" are different.

Call me stupid but I dont see it either. While the BVC does have two holes instead of one the air still goes through a single throat. The difference's I see after dissecting is the packing material surrounds the vertical coil with no wick in the center. So its like a dragon coil. air passes thru the coil not over it

From my experience I really feel the reason the performance is so good compared to BDC's is quite simple. First the airflow is going directly through the coil I find this produces a faster heat ramp up because the air is touching the entire coil and not just one side. The Second reason is that the wicking material is wrapped around the coil instead of going through the coil which means the coil is almost always saturated entirely which means it can vaporize more ejuice at once thus creating more vapor and better flavor. The issue with this is it creates a really tight draw and can cause lots of dry hits when lung hitting because of the massive airflow and not being able to keep up with the wicking due to 4 small holes being the only entrance. Mouth to lung produces less airflow so wicking is much better. Now if only they would design the BVC coils with 2.5 - 3 mm holes for the juice to wick into they we would be set.
