Wraps, wraps, and more (or less) wraps

[Jerms]

What differences, either subtle or big, do you notice with different amounts of wraps for a coil when used at the same watts. I'm most curious about dripper RBAs with silica, but feel free to post your experience with other set-ups as well. The one definate difference is more wraps will need more volts to reach the right watts, but I'm looking at quality of vape. Do you notice a difference in flavor or vapor? How about the reaction time of the coil, how long it takes to heat up? Do you have a prefered number of wraps?

Please include type of set-up such as wick material and wire gauge. And feel free to post anecdotal thoughts. If you feel one way gives better flavor but don't know why, share anyways! As long as it's been your experience there's no wrong opinion. Or, do you have a theory why a certain number of wraps works better? Post that too!

If your working under 15W its not even worth it on an rba... (my opinion & experience)

wraps are subjective to the thickness of the wick you are wrapping it around.
ohms is what you are trying to achieve, when you wrap a certain gauge wire around a certain dia. wick.

the size of the air chamber and air hole to that chamber also determine how the coil affects your vape.
The larger the air space in the atty the cooler and smoother the vape.

you have a long way to go, keep experimenting and you will be able to answer your on questions

This is true, there are other factors to take into account that make a bigger difference in vape quality. I'm looking at; when all other factors are the same, what's the differences noticed with number of wraps. I've noticed some differences, they are subtle but still noticable, and curious what others have experienced.

With all other variables the same; more wraps cooler, less wraps hotter...
for me all other variations in vaper, flavour and performance are minimal.
*in single wrap increments.
** This excludes SLR(super low resistance) coils as one coil can make a difference of 0.3ohms depending on thickness of wick.

if you have a variable wattage/voltage device, this shouldn't even be a concern, as the mod can compensate for those changes.

thats my view on it

Here is what I have found:
Smaller bore coils with more wraps that are scrunched together so they are touching produce a brighter flavors. They also seem to run much cleaner than a large bore evenly spaced coil. In the following pictures, both coils are roughly 1.2 ohms, but picture 1 has large bore, picture 2 has micro bore (1/16" or less ID). I no longer use large bore, evenly spaced coils, rather I prefer micro bore by a large margin.

You will also notice that you can add a few wraps and increase the resistance above your typical sweet spot and it is even more spectacular tasting.

Yep, this would apply to only vv and vw, since with fixed voltage devices like mechanicals the wattage would change with resistance.

So I guess what I mean is all variables are the same EXCEPT voltage would change with resistance to match the wattage.

hey Super X Drifter, what RBA is that....
i like the symmetrical layout and have been looking for something like that for one of my current projects.

I Had the impression that the more coils would raise the ohms or is it because the larger coils are the same length as the micro coils therefore they are the same ohms?

not really, adjusting voltage is just compensating for low/high ohms. all variables will change slightly, but your biggest difference will be the heat you feel.
this is really hard to describe, and the only really way to understand it is to try different variations yourself.

like with SXD's example same ophms & same volts. but change the shape of the coil... and voila different sensation.

even the various types of VW/VV mods hit differently, even when set to same voltage.
only way to know is to try...
my setup is different than yours, so what i change, may not reflect the same results that you would get.

Thanks Super, that's exactly the type of opinion I'm looking for! I started with tight coils on a small wick, moved onto to bigger diameter wraps spaced out, but finding myself moving back to the small bore, touching coils like on Cisco-spec atties. I haven't decided yet which I prefer, but have noticed a fairly big differences in the vape quality.

Both are a factor, more wraps or larger wraps raise the resistance. It's the total length of the wire that results in how many ohms, not how you wrap it.

Hey Killa - those are chalices bro. I just sold one yesterday. They are off the chain!

OH ok gotchya

Veezy, correct, same amount of wire = same resistance - just different bore of coil allows for more wraps.

One thing I've noticed, and a reason I think the wider spaced coils seem more popular than more wraps that are bunched together, is it's easier to set-up the first way. Especially with silica, wicking becomes more important with more wraps. When they wraps are spaced out there's more room for the wick to stay saturated, but when they're close, if the wick gets choked off a little bit or the wicking can't keep up, it's no good. So far though it seems taking more time to get a closely wrapped group of coils seems worth the effort for better flavor.

10-4 brother. I am over those stretched out slinky look alike coils. Performance is so much better for me with a micro bore and cotton wick.

Another benefit I'm noticing, when the coils are touching or almost touching, they seem to go longer before gunking up. That's a big one for me cause I vape a lot of gunk-prone NETs. Not only the spaces in between that seem to gunk up faster, but for some reason the actual wire seems to stay cleaner in close quarters.

Totally agree. I run only inflavored nic base and my coils (and wick for that matter) remain spotless. Unflavored is very easy on vape gear

cool this is awesome info thanks guys. M hybrid has a 3mm wick hole and i really like the 3/2 wrap i have on it now and my coils are spaced out equally (not close to each other) in my position i wont be able to use micro coils with the same ohms I would actually have to use longer wire. I just gave it a go and it took awhile for it to heat up I tried a 6 wrap with 28 gauge and just didn't work out as i was hoping it to

Veezy, the micros may be better suited to bottom fed and dripping attys. I have never had a good vape with large bore coils and increased resistance. Large bore seems to favor low resistance.

I know nothing very little about electricity (except that it'll shock ya) but I did stay in a Holiday Inn Express last night
