Instead of .55ohm from a single 26ga coil try a more robust build. Dual parallel dual coil 26ga around a 3.18mm post for 15 wraps. It'll be .56ohm and over ten times the surface area. I'd encourage a 26650 Atty with a lot of airflow too.
Now for some science calculated from steamengine. Your coil is at 1127mW/m² of heat flux I usually vape around 150 to 170mW/m² my mech mod with quad coil 24ga 7 wraps around a 14ga needle at .16 ohm is 110w at 158mW/m².
The build I posted on top should get a heat flux literally the same as the wattage +/-1 depending on range. I have it sitting in a mutation xl and I can fire it on a mech in about 12 seconds. It isn't a feasible build until 120w+ so your god mod should be able to use the full potential.
If it won't fit try 22ga dual coil 17 wraps around a 3.18mm post. Should get you around the same performance just less surface area immediately touching the wick.
