So I never did a dual coil build before. I guess I felt I should master single coils before messing with duals. So yesterday I finally did my first dual in my Troll, 7 wraps 26ga for a build that reads 0.35 ohms.
With a single coil 0.5 ohm build and airflow closed on one side in the Troll I can max out my DNA40 at 40w and comfortably hit it til I run out of breath. With this dual coil build it seems hot and I just can't hit it like I hit the single coil. Steam Engine says the single has a heat flux of 88 and the dual a heat flux of 32, both low but very low for the dual.
So why does the dual give me a rougher vape? It isn't an airflow issue, the resistance reading is rock solid and doesn't jump around, my coils heat perfectly evenly inside out and at the same time on both sides, I have a ton of airflow. Any ideas why this build isn't vaping well?
