Is so much better then 2-3ohm builds?????? and why is 4-5 wraps so much better then 7-8 wraps?????

I have a KFL + and Russian 91% and currently only have 32 Guage wire I wrapped on a 1/16 drill bit 8 wraps and have a 2.9ohm coil and I love the way it vapes at 10-12W..... since I am new and wouldn't know any better what would make my vape much more supreme with a sub ohm or 1.5 ohm vs my current 2.9ohm build????

You are vaping on a VV/VW device, so ohms is not as important. When people vape on mechanical devices with no regulation, they use ohms to change the watts.

For instance 4.2 volts on a 0.3 ohm coil is close to 60 watts, while 4.2 volts on a 1.5 coil is 12 watts. Lower ohm equals more heat.

A lot of people vape on VV/VW devices and turn the watts up to suit their needs.

vapor production goes through the roof with a sub-ohm coil. I recently started building coils for my RDAs and find a 1 ohm coil may be my sweet spot. I have 26 28 and 30 gauge wire. the 26 and 28 are easier for me to build a micro coil when compared to 30 gauge. I would imagine 32 is trickier yet. trying different builds with different wire will lead you to your best suited coil. you should also read as much as you can find here on the subject of ohms. always be safe and good luck

yeah wrapping the 32 Guage tight into Micro wasn't the easiest thing in the world but I got it after a few tries. I am looking forward to the 26-28-3) Guage to come in the mail as it should be much easier for me to wrap not that I got the 32 out of the way.

It's not the ohms that count so much as the watts.

Other than that, thick gauge wire take more power to heat up.
And.
Two coils in parallel on the same voltage are going to have half the combined resistance and burn 4 times more power and make more fog.

doesn't seem like it takes more power to heat up that thing fires good at even 8-10W and that's 32 Guage 2.9ohms so maybe I just don't know what a real vape feels like yet lol

Correction: fixed my post; meant to say "thick gauge" wire, not "high gauge" wire.

Depends. You are vaping on a regulated mod, so it doesn't really matter too much except the thickness of the vape (with thicker wire, you cover more surface area, say you do a micro coil and you get a much denser vape at the same wattage). It comes into play when you are using a mechanical mod, where the resistance of your coil directly dictates the wattage you'll be vaping at. (Ohm's law).

Vaping at higher wattages usually means more intense flavor, a lot more vapor production and usually when you start vaping at higher wattages (or sub-ohm) you drop your nicotine level.

I'm still confused then why can't you vape at just as high of a wattage with a higher ohm say 2.5 instead of 1 ohm or sub ohm what makes sub ohm more intense vapor and flavor....

Because a regulated mod has a limit (15 watts, 20 watts, 30 watts depending on which mod). On a mechanical you don't set the wattage, the lower the ohms of the coil the higher the wattage it'll output. A 0.6 ohm on a mechanical will output, say, 20 watts, while a 2.5 ohm coil will put 5-6 watts. A 0.3 ohm coil will output over 40 watts, etc. Also, thicker wire means more surface area, a denser vape as opposed to really thin kanthal wire. Also pushing too much wattage on such thin kanthal will make it taste burnt as the coil heats up faster than thicker wire, the wick can't keep up.

Then again when sub ohming on a mechanical battery safety, proper knowledge of ohm's law and an ohm's reader/multimeter to check for shorts is a must.

I am talking about people using DNA 20s and 30s. They are all saying lower ohms vs higher.... so is it just the surface area of the thicker coils then that makes this better? I mean my 32 Guage is very thin and it was actually kind of hard to roll into a micro coil but I did it and it works great at 2.5-3ohms

You can't push 30 watts on a 2.5 ohm coil. Do it and it'll taste burnt. It'll heat up faster than the wick can keep up. The happy medium is 28 gauge kanthal. There isn't much of a difference between firing a 1.2 ohm coil at 20 watts and a 0.6 ohm at 20 watts, except heat up/cool down time and density of the vape as well as a tiny difference in flavor notes. The differences are very subjective.

You can.

However the average lithium battery is more like 5 to 20 watts.

So the average regulated mod that steps up voltage is designed for that kind of wattage.

Of course you can push 30 watts on a 2.5 ohm 28 gauge coil.

Not on a 32 gauge, though; that would burn out at 32 gauge.
