    Q About Dual Coil

    I have an IGO-W dripper and want to try a dual coil set up. A few questions first. Do I need 1 air hole above each coil or can I just have the 1 air hole? Am aiming for 1 ohm so do I make each coil ! ohm or .5 ohm?

    Each coil should be 2ohms, the resistance is halved with dual coils. Two air holes wil give you the best performance also, go for it!!!

    so.............. i figure will use eko wool 2 mm and shove 1 mm eko inside as the wick. fiddily but got it done. 7 wraps of 30 gauge kanthal, shoulda used 28 methinks, for measured 2 ohm each. another 20 minutes to get them screwed in, attached to vamo for a reading of 0.8 ohms. my htc really didn't want to focus, best shot out of 10 below. seems to give more flavour. only have the 1 air hole though cause i don't have any teeny drill bits

    This is my dual coil setup on a Igo-W http://forums.aussievapers.com/vendo...tml#post314083

    nice. you got 2 air holes and what resistance?

    The total resistance with a 6 wrap first coil 5 wrap second coil is 2.4 ohms combined. The Igo-w came with 2 small air holes, around 0.5mm each, way way way too small, I drilled one airhole at 2mm and it vapes perfect, some people drill each air-hole to 1mm so that equals 2mm total. really if I was to do it again, I would block both small airholes with some wax and drill one 2mm airhole where the coil sits, about 7 mm higher.

    Just remember when drilling you're dealing with areas, not linear measurements...

    So two 1mm air holes = 1.57mm^2

    Two 2mm air holes = 6.28mm^2 - that's 4 times the amount of air hole

    Yes that's true but keep in mind the difference between cross ventilation vs direct air flow, plus one setup would be 2mm plus .5mm and the second is 1mm cross 1mm.

    For sub ohm coils i would be heading towards dual 2mm if not dual 3mm
