Question about ohms

[mrdfield]

So I have a kayfun v4 clone what ohms would anyone suggest I have 28 g kanthal
And will be using a Cotten wick
mod is a vaporshark rdna 30
I a planning to thy a 1.1 or a 1.2 single ohm coil
Any one have any thoughts on this build
I am looking for flavor not clouds
Please let me know also wattage you think would ok to vape on thank you all

My fav kayfun build is 1.5 ish with 2mm id. Start at 10 watts work your way up. I usually stop at 12. But this is just what suits my taste.

Although some values are subjective - There are optimal builds for every wattage, and an optimal range of wattage for every build.

27 gauge at 1.0Ω+/- would offer a good surface area (9 wraps +/- on a 2.4mm mandrel), low "heat capacity" (time-to-temperature) low leg loss, and a broad range of wattage adjustments. The same can be said of 28 gauge... with a minor decrease in surface area, but slightly higher temps and reduced lag (HC) time, for a given wattage.
Should you go as thick as 26 gauge, you begin to run into efficiency and performance issues.

As an example, should you want to run the full 30 watts... 27 gauge, at say 1.2Ω, might be a tiny bit warm for you, with an HF (heat flux - coil radiant temperature) of 313 mW/mm² - but it does allow you a broad range of wattage adjustment - as low as 15 watts with a cool HF of 157 mW/mm², and a corresponding increase in coil temperatures, to the previously mentioned peak HF... as you increase wattage.

Here's but one example, with 28 gauge and 1.2Ω resistance at 20 watts... a warm 296 mW/mm².

Thank you for your reply I'll have to learn more about heat flux

No worries Mr. D...

I don't know if you can access it via an iPhone, but if you can, click both my first and second sigline hyperlinks. I've written a series of articles that will guide you in using Steam Engine, and optimizing all the variables to produce your desired vape.

I have rebuilt my Aspire ET-S using 28G kanthal, 9wraps on a little screwdriver(should be about 1-1.5mm) got 1,2-1,3 Ohms and I am really happy with it

A 1.2 to 1.5 ohm coil on a Kayfun will work great. That's the range I used on mine and got a very good vape. Keep it simple - no different than your Aspire coils - and it will be fine. If not what you expected you can always go a bit higher or lower to your taste.
