UD IGO W Clone rebuild question

[keegan]

so I recently decided to get into the whole aspect of vaping that is "chasing clouds", and my first step was to buy a rebuildable atomizer. I purchased the UD IGO W clone (the one without the holes in the posts). After a few tries, all failed, I came to this dual-coil build, using kanthol wire and organic cotton. The problem is that no matter the build (and I've tried different numbers of wraps, single-coils, etc), the vapor it produces is minimal, very hot, and tasteless. Because of that, I won't vape on it, seeing as that seems dangerous and unhealthy. It seems I am doing everything correctly, according to the various tutorials I've seen. So at this point, I'm confused. What am I doing incorrectly? Any advice would be much appreciated. I could take more pics if needed
My setup is the Magneto Mechanical mod, and a 1600 mah IMR18650 3.7 V LI-MN battery.

Your problem is that the IGO W4 comes with tiny little pinholes for airholes in the top cap. You need to drill them out to whatever you need.

Rule of thumb air holes:
1.8+ ohms - 1/16th air holes
1.5 - 1.8 - 5/64th air holes
1.2 - 1.5 - 3/32nd air holes
0.9 - 1.2 - 7/64th air holes
<0.9 - 1/8th air holes

That makes a lot of sense, thanks for the advice Nataam. Would you recommend drilling out the one hole bigger, or drilling another hole opposite of the existing one?

Its good to have 2 holes on opposite sides of each other if you are running duel coils. That way air can come in across both coils. I think you will enjoy it alot better.

thanks for all the advice guys. i really didn't think proper sized air holes had that much of an effect on the performance. if i were to drill holes on opposite sides, would it make sense to drill smaller holes since there are two?

What he said, if your doing dual coils you need two holes on opposite sides of the cap from each other. Always make sure to line up your air holes with the coils.

no matter 1 or 2 holes start small and go up. You can always move to the next drill bit up but putting metal back into place after drilling out with too large of a drill bit is impossible.

they also sell top caps for the igo-w with the holes pre drilled larger.. some frosted clear and other shtuff, just gotta look around a couple places. I've read people round these parts say they own a few top caps with different sized holes, set up for dual and single so they can be interchanged and basically give you an adjustable airflow rda..
