Any advice on a build for the SXK 2k16? I use a DIY NET e-liquid with essentially 95% VG 5% PGA. Tried 28 gauge and 30 gauge Kanthal spaced 5-6 wraps 3mm id. Very tight draw. 9-10 watts. Have been getting the gurgles. Also seems the coil is gunking up faster, even for a NET...
I like a cool vape, preferably something I can use on a mech mod as well. Oh, and some fries with that, thanks.
I personally use a 2.5mm ID, 7 wrap, 28 gauge build in my 2k16's. Like you, low wattage (lower, actually...7.5W) and a tight draw. May get the occasional gurgle, but nothing to write home about. As someone suggested, you may be drawing in too hard for the amount of wicking you have. But, with a 3mm ID coil, I'd suspect your cotton it pretty tight in the wick channels unless you thinned.
That said, I'd try a smaller diameter coil. It could be with the 3mm ID, and the associated amount of cotton, you have an excess of juice getting to the coil that your low wattage isn't completely vaporizing (which may also be causing the coil to gunk up quicker). Add that to the increased pressure from a tight draw, and you could get the gurgles.
Usually, these tanks are pretty forgiving...I just "cut it and stuff it" when it comes to cotton.
As far as NETs. That's all I vape, and I need to dry burn and rewick once per day. I can get 2 days if I don't really care....just as info.
