Ive been vaping on my Sigelei 100 watt plus and a tobh 2.5 clone from when I started vaping. If I go up to 90-95 watts my cotton burns and destroys my throat because my coil heats up to quick. I need a coil that is vapable up to that wattage. I only have a 2.4 mm screwdriver and 24 gauge wire (LOADS, 100ft). I only vape dual coils.

You may well be reaching the upper wattage limit for cotton wicks. cotton can only wick so much fluid so fast to the hot coil. I knew there had to be an upper wattage limit for cotton wicking, was just not sure where it was.
Why do you have to vape at 90-95 watts? Just because the device can doesn't mean you have to.
Why do you have to have dual coils only? Single coils can perform just as well.
I recommend maltbys25 build though, twisted 28g always gave me a great vape. You could have too much cotton and choking the coil so it's burning it as well.

If you want to go ultra high wattage then, IMO, you might want to run multiple coils - quads or octas with a thinner wire. More coils = less power power per coil and less chance of burning the coil - but higher juice consumption. Quicker cool down... But just my opinion.
Check out steam engine. It has a heat flux feature that will show you approximately how hot your build will be at a given wattage.

As someone once said....just cause you can do a thing, doesn't mean you should do a thing.
I get tons of vapor on my Sig 150 at around 30 watts with Subtanks and 40 watts with Delta 2s and only have to charge them every three days. At the power output you're using, you have to be very careful of your batteries (yes, even on regulated) and the high probability of cotton fires. Just my opinion...

I just want bigger clouds thats all. I vape at 60 watts for now. Doesnt lower gauge wire and more diameter mean more surface area for the heat to travel? Do I have to buy a 3 mm or 4 mm screwdriver and try that ?
Rodicle, here is a great read for you.http://www.e-cigarette-forum.com/fo...ughts-about-sub-ohm-latest-vv-vw-devices.html I have done this and built a 1.0 ohm build dual coil and it produces lots of clouds but of course good airflow helps out with vapor production as well as keeping those coils cool enough not to burn the cotton while running at higher watts. I used 26 gauge for my build with I think it was a 2mm inside diameter 15 wrap. Personally I found that I didn't like the amount of juice I was going through just for the clouds it produced but to each is their own. Hope this helps.
Higher wattage on a higher resistance will equal more power. We can't forget about voltage.

Higher wattage will equal more power, regardless of the resistance. Thats what wattage is.
Power was a bad description. .2 ohm at 90 watts is going to vape different than 1.2 ohm at 90 watts. Voltage still plays a role in the equation.

0.5 ohm dual coil should do it.
here it is:
Coil wrapping | Steam Engine | free vaping calculators
10 wraps on 3mm
If you're using the same wire gauge, and same coil thickness, the 1.2ohm is probably going to produce much more at 90 watts than the .2.
oh; missed the 2.4mm screwdriver.
that's 12 wraps.

That sounds right for putting out big vapor. I'd be more inclined to find a 3mm and go 11 wrap, just so you dont run out of juice at the coil, and get a little more warmpth in the vape, but that's me.
You didn't give us enough information on your build Dodicle. It would have been nice to know the resistance so we would have been able to calculate how much wire you're using.
The problem isn't that the coils are heating up too fast, it's that you have too many watts per square mm of wire surface area for your available air flow and wicking. To have maximum air flow you need to have all the air holes open so be careful when you put the cap on.
Going to the Steam Engine coil wrapping calculator, I've set it up here with 24 gauge Kanthal at 0.2 ohms so that the heat flux at 90 watts is 497 mW/mm². I'm pretty sure that will burn juice even with all air holes open and good wicking and I'm betting this about the resistance of your build. It's 5 wraps on a 3mm pin. If you're using a smaller pin that's fine, just adjust the diameter in the calculator and you'll get the correct number of wraps for the pin. I would not go all the way down to 2mm, I prefer a bit bigger for higher power setups, but if you want to try it go for it and see how it vapes.
I changed it to 0.3 ohm by adding two wraps to each coil. Here's what it looks like at the same 90 watts. The heat flux is now 331 mW/mm² and that will not burn juice. You'll also be able to turn it up to 100 watts and be OK.
Let us know how it goes if you try it.

Thanks, So 5 wraps on a 3mm screwdriver would be fine. Just gatta get my lazy ... to go to a hobby shop[emoji1]
at 90+W only thing that is gonna last at that heat is silica.... BTW do you like Habenero peppers?
