Touching back on single cell mech builds..

[vapdivrr]

This may be worth some more discussion. I was building 1.4 ohm single coils with 28 guage stainless and found by trial and error I preferred 30 max watts. Steam engine says I need 30 watts to get to 200 heat flux. It also says if I use 30 gauge wire and the same 1.4 ohm resistance I get to 200 heat flux with just 15 watts. I tried that and found I prefer to vape the 30 guage at16 max watts. I've been building with 30 guage ever since. It's not a free lunch. The 30 guage build is using a lot less wire and seems to produce less visible vapor but I want that. Battery endurance matters to me and I estimate may be I'm getting 20% more puff time.

Single 30g coil at 1.4 ohms and 30 watts? Seems to high for such a thin wire

I agree.
Steam Engine assumes that all things are equal, and Murphy's Law has proven that pie are round ... not square!
This makes Steam Engine a good place to start, but more often than not, it won't be the "end run" with any given atomizer. (or user) There will always be the "YMMV" factor.

I like 30ga (kanthal) for many reasons. Quick ramp up & cool down, battery life just to mention a couple. With my atomizer it works best in the 8 watt range, but that has nothing to do with what wattage would work best in your atomizer. So again, YMMV.

I need to fire a 30ga coil at that high a wattage just to see what would happen. I think it would just pop.

Add:
Silica won't scorch ... that's the point.
Been a long time since I read the numbers, but it seems like it was something like 1,000 degrees before silica burned.

With fitting airflow and good wicking a 30g parallel 10 wrap will work at 30W. Its kinda my all day build. I use SS but there is no reason why Kanthal wouldnt work just as well.

You mis read my post. I'm fiiring 30 gauge wire build at 1.4 ohm at 16 watts, not 30 but apparently I overlooked that this thread is about mechanical mods. I don't use those so my comment is not relevent.

I can assure you that will never happen in my RDA

I'm no expert but it appears to me kanthal is hanging around because starting resistance is higher. That's helpful if the goal is to create a lot of vapor. With kanthal there can be more wiire to vaporize more liquid. I'm not interested in making a lot of vapor so I don't need so much wiire so stainless works fine.

So I got a copper mech and I was right way more conductivity than the aluminum tugboat garbage. I found my solution for me personally I will use only copper mechs if I'm using a mech. It wasn't my builds rda or battery!! Just less power on the aluminum mod great for flavor builds though!!
