Optimal build for Kayfun on DNA30D

[nexus3]

Hi,

Could you please suggest an optimal build for kayfun (3.1/L+), so i could enjoy the capabilities of the mod fully. I tried microcoil 10 wraps of 0.4 mm Kantal on 2.2 mm drill, and 13 wraps of 0.4 mm Kantal on the same drill, it vapes good, but i am not impressed, i can not quite find any difference in the vapour production, between this set up and properly build kayfun on my Provari 2.5. I wick my builds with organic cotton.

Thanks in advance for the suggestion, and please excuse the Metric measures and the non-gauge ones of the mentioned used wire

On either my ProVari Mini or VS rDNA, my KayFun is set up at 1.4 ohms . . . Using 30 ga. Kanthal A-1, wrapped around a 1/16" drill at 8 wraps.

ETA: I use either a Koh Gen Doh or Koga cotton pad for the wicking material.

Helpful coiling calculators.

Here are a few links for you regarding building coils and getting the resistance just where you want it:
1. Steam Engine
2. Coil Toy Calculator

Make sure to check your build with an ohm reader or DMM before putting it on your mod and firing it.

I usually do a 1.3-1.4 ohm build with 28 gauge and I make a normal wick and then add a nest/donut around my coil for more vapor after I add the first piece of the chimney.

On an rDna i would say build it at about a 1.5 - 1.8 ohm resistance, and push it at about 17 - 19 Watts!

That's a bit too much for my KayFun set-up. I'm usually at 12 watts. However, for my 1.5 ohm 1x coil Magma, it vapes great at some 18 to 23 watts.

You can't!!!!!
You need more air flow & wicking for 30 watts.

It's the same topper, why would you think a different PV would make it vape differently.
With a DNA30 you simply need to make sure that you have enough resistance for "step up" to work at your desired wattage.
ex:
I use my KF @ 9 watts, so the lowest I could go with the resistance is 1.96 ohms.
If you want 12 watts, you need at least 1.47 ohms.
18 watts, 0.98 ohms
and so on.
The lower the wattage you want, the higher the resistance you need for the DNA chip set to work.

So a 3 ohm carto tank sure works nice on a DNA

Ok, so does the diameter of the wire matter?

I do this style of build. I do 6 wraps 28 gauge = 1.3 ohms @ 14 watts Works really good on a DNA 30 mod or a Provai @ 4.2 volts

You certainly can!
Mine currently has a 1.4ohm 28gauge kanthal 3/32 coil on it and I can run it all the way up to 36 watts(ipv2) before it starts to taste off. Even running it lower at 26 watts it still produces plenty of vapor instantly.

You don't need a certain resistance to be able to use certain wattages, you just have to build it correctly and wicking fast enough.

I can chain vape at those wattages as well and never get a dry hit or gurgle so long as I have it wicking properly. I use rayon for wick.

Think this through. Resistance is determined by the gauge (diameter) of wire and overall length of the wire between the posts. Longer length of wire = added resistance. Larger diameter wire = less resistance.

Think of resistance and wire gauge as a hallway. A narrow hallway (high resistance) restricts the number of people (electrons) who can pass through the hallway (narrow wire). A wider hallway (low resistance) allows more people (electrons) to pass through the hall (thicker wire).

Larger loops makes the wire longer, hence increases the resistance. Larger loops allow easier insertion of the wick material, and allows more wick to be used. More wick = more e-liquid to the coil = more vapor, up to a point of diminishing returns if too much wick causes strangulation of the fibers and inhibiting liquid flow.

DNA30 and ipv2 are two different animals. Yes you can fire a 1.4 ohm coil @36 watts, just not in a kayFun.
LMAO I want to watch you vape 36 watts through a KayFun (smoke ... not vapor ... would come out your ears) There is simply not enough air flow through a kayfun to do that! Better take those asbestos liners out of your lungs, I hear they cause mesothelioma.
Why do you think we drill all those great big holes in RDA top caps?!?

Maybe you should re-read my post, because that build is in a kayfun. No smoke, just vapor. No, it isn't too hot. The airflow through my kayfun is nearly 1/16th stock all the way through(when I checked it I think it was 1.39mm on the outside and 1.59mm through the positive shaft to build deck), that is plenty of airflow. 1/16th is 1.587mm so close enough

I typically run it at 30 watts, which just so happens to be the max wattage on a DNA 30, which was what the OP was asking about. So yes it is possible, and quite enjoyable if you build it properly.

You "drill all those great big holes in RDA top caps" for the purpose of direct lung hitting, and to cool down all those ridiculously stupid low ohm builds(which are running much hotter than 36 watts). The OP was not asking about that though.

Just because you can't make it work, doesn't mean it's not possible. I run my kayfun like I do every day, and it performs great. I have also done the same build for a few friends and family members and every single one of them is perfectly happy with it. In fact they prefer it over other builds, so either I am doing something right or you are doing something wrong.

Edit
Read around sometime, there are threads on ECF where people are running a kayfun at 50+ watts. They had to open the airflow up with a drill bit, but it is still a kayfun!

Twisted 30 on a 5/64 mandrel, 8 wraps @ 1.3 ohms using KGD

 

[coalyard]

I am vaping my Kayfun with a 3 strand twisted 32ga coil at 1.2 ohm at 13.5 watts. That is pushing the limit for what a Kayfun can efficiently wick.

If you are looking for lots of vapor production, go with an RDA on your 30W device. I am currently running a .5ohm dual coil in my TOBH wicked with Koh Gen Do at 25 watts on my DNA 30. It is wonderful.
