So I'm not new to rebuilding, but I recently decided to up my vape from a mech mod to a hex ohm. So I have a .35 build, 24 kanthal, 2.5 id, 9 wraps. Can someone explain to me why anything past 50 watts just tastes burnt? I'm sure it's not my wick because it wicks fine and there's no signs of burnt cotton. The juice is diy 85vg with low nic, so it's not my juice. Do I need even more surface area then that?
Mutation x v4 .35 build help

I too have the mutation v4 but never had this problem. Are you chain vaping? If so it sounds like its not wicking fast enough, I regularly run a 0.3 ohm 22g coil at 70 watts. How much of your air flow is open?
I can chain vape a few hits around 50 watts no problem. But as soon as I go past 60 it's burnt on the first hit. The airflow is wide open, the vapor is a little warm but it's odd how awful it tastes. I've Rewicked it a few times today all with the same result
Try using a little less cotton, you could have to much in and its choking which will prevent it getting in to the coil
^ Yes. That is correct, or I certainly think it is and I don't believe I'm alone there. Perhaps this juice is just not good with that kind of heat, unless you can conclusively say you've used it at the same power before with decent results.
I have vaped some cheap juice at high watts and it made me gag.
Yes that is correct different juices vape better at different watts but the op says he's using 85% vg, higher vg juices tend to need higher watts.
85% VG / 15% PG? Sounds to me like its a wicking issue for sure. Keep in mind VG is thicker than PG so give the wicks some time to catch up. If you can - try different wicking materials as well. I'm currently bouncing between cellucotton and PIMA cotton. I find that both wick extremely well with 80% and higher VG based juices because of the fiber layout. If you haven't already - crank it to 60W and paint the coils with juice and vape it then. If it's still tasting burnt then its not a wicking issue at all, but a hot spot / hot leg somewhere, at which point, remove the wick, pulse your coils, and try to identify the problem. Hot legs are generally caused by poor connection - so tighten the screws. Hot spots can be caused by uneven coils - insert screwdriver, drill bit, etc that you used to wrap it on, and pull out and up on the coil. Hotspots can also be caused by the coil making direct contact with the post / post block, so a little space is required here. Host spots may also be caused by the leads from one coil touching the back of the other, so if you didn't cut them close enough, remove of of the coils, cut the leads flush, and repeat with the other side.
How does direct contact with post / post block cause hotspots? Well the post stays cold - whereas the coil gets hot, which keeps that area of the coil cool - while the rest of the coil heats up causing a hotspot on the side heating up. Also may cause a short - which if it's being fired on a regulated mod, it should show the 'SHORT' error. Not all the times it will show up unless the chip senses a drastic drop in resistance or drastic pull for power.
I currently vape 80/20 and 90/10 respectively at 3 and 0mg nicotine - and from my experience - more times than not, it's actually a coil issue than a wicking issue. But to determine that, try what I explained above. If not, maybe running it at that high is just too much power. As I find that anywhere on KA1 and N80 wire - 3.7V - 4.2V are the sweet spots for those wires. Remember - just because your MOD goes past a certain wattage and voltage doesn't mean you should throw that much power at your setup. These devices that use 40+ watts of power were designed to fit the needs of a large group of people. Try to use a lower AWG wire (22, 20, 18) if you want to jack the power up, as those wire gauges will surely need it.
Throwing more than 4.2V at anything is a bit excessive. Because at target resistance:
.35ohms @ 60W = 4.58V
