I'm looking for a guide on the what and why of coils, but I just keep coming up empty.
I can consistently build .3 ohm micro coils out of 24 gauge A-1 kanthol that work well with my mechs (yes I'm using good batteries a pair of Sony vtc4 and vtc5 for powering my 2 mechs, a nemesis and a stingray both solo 18650 tube styles) I'm getting good flavor and good clouds on most if not all my RDA's. I'm looking on how to tweak coil builds for what I want it to do. How do I get better flavor? Whats makes for bigger clouds? If I increase the ohms what can I expect to happen to the vape quality? (Less cloud if I leave the wattage the same, but what else?) How do I alter vape density? \\

I know a lot of this is answered "just try things out and see what you like" but there's just so many variables that I get lost on where to begin my trial and error experiments. And most tutorials are "just do this and it will work" which was fine for getting me to where I'm at now, but frustrating now. Heck until a friend just couldn't handle the wide open airflow I've been tooling around with on my Mutation x2 I would have never realized by I could get a little more flavor out of a tighter draw.
Is there a good reference for what does what to your builds? Heck even a small rule of thumb like more flavor comes from cooler vapor or some little ideas to guide me into what I'm going to change by changing what on my build?

Thanks for the help. Cheers!

The steam engine calc is a great help for putting things in perspective. Having a mechanical can also help since you use a fixed voltage as a independent variable.

What you should look into is the heat flux (manipulate the wattage) and surface area (in advanced) on the coil building page. The calc shows a color as a guide for heat which is easy to understand. You want to try to get decent surface area too with contact coils.

Plug in your kanthal gauge, the internal diameter of the coil, and select the amount of coils. Now you can input the resistance you wish to use and play around until you like the outcome. You'll be working on a full battery charge theoretically, so match the wattage in heat flux depending on the battery voltage and resistance, there's a separate page for the ohms law calc too.

You can try out different things like changing the coil diameter to change the number of wraps, see how the surface area plays into it based off a coil you currently use. You can try a spaced wrap for wick longevity or even different coil set ups.

The reason I don't suggest. Well try this.... Is simply because I don't know what you like. What tastes good to me may be tasetless or taste horrible to you. Besides there are hundreds of threads on this forum asking and answering that question.. NONE with the same answers. METHODICAL Trial and error is the only way to find what you want. That does not mean you have to try every trick build that you hear of.. That may mean you find a build you can do, and PERFECT THAT. THEN try something different. For example you can not say single coil builds suck, because the 1 single coil you built sucked. That build sucked, the other million variations of that build might not.
