Dual Coil has got some fight....

[John_]

So I got a Silver Bullet on saturday and love it, dual coils on a Phoenix V5. Up until this morning I've been vaping all DIY no nic juice and everything was awesome. This morning I put 6mg Gorilla Glaze in it and holy crap... that first drag I did a nice big lung hit and BAM I was coughing for awhile after that...

I always knew I was getting more vapor but I didn't realize how much more I was vaporizing than in those stock clearomizers and such.

Anybody else do something similar?

What I'm Using:
Silver Bullet
Flat Aluminum Drip Tip
Kick V2 @ 15 Watts
Two 1.8 Ohm Coils (32 Gauge Kanthal, Threaded Ekowool)
AW IMR 18650
Phoenix V5

Yeah, my first d.c. In a nimbus clone was way heavy. I had to drill holes on the opposite side so both coils got the same amount of air. Otherwise the coil farther away is hotter then the closer one, and acts like it is half the resistance of the closer one. In effect, what should be two 1.5 ohm coils acts like one 2.8 and one .2, resulting in a harsh vape.

Try putting two wires together and wrapping them side by side (not twisted) and very tightly spaced, touching as much as possible but a little separation doesn't hurt either. Heat time is slightly improved and it performs better than the separated coils imo.

I'm sorry I don't understand, could you provide a video or pictures? Why not just make a microcoil?

The Phoenix V5 I got had holes on two sides already. I always check when I'm putting the cap back on that I put the holes right next to the coils.

I'd rather have two wicks feeding juice.

Sorry, I don't have any way to take pictures. It's making a microcoil with two wires instead of one. Just put the two wires side by side and start wrapping. The advantage is more surface area on the wick. I don't have a wicking problem but I only chain about 3 puffs in a row before resting a few seconds.

I first ran across the idea in one of the threads here and I'm thinking there was some pictures, but I can't remember which thread. It's basically a way to make 32 behave more like a thicker gauge wire.

I get what JD1 is saying. I've seen it done in gennys and have been meaning to try it, now that i've been reminded of it i think i will try it later on today...
Basically, fold say 12 inches of wire in half, so you have 2 6" lengths of wire next to each other, and wind them around the wick the same way you would wind 1 coil, so you essentially wind up with 2 coils right next to each other on the same wick. Like he said, it makes it behave like a thicker gauge wire.. i think it'd be effective because it gets you more surface area, while still being a nice low resistance. More heat over more surface area= more vapor production.

I recommend trying two or three of them when you get the chance, each a slightly different diameter. Below 1/16th it becomes too hard to feed in the wicking meterial imo, so I suggest trying 1/16th, 5/64th, and 3/32nds. But what you're fine tuning here is the final ohms you're shooting for.

As far as heat times go, the lower the better, but there are other considerations, especially for those of us that like a relatively cooler vape and also firing the vv device if that's what's being used. I personally shoot for about 1.4 to 1.5 ohms for my 804s because it keeps it safe for the batteries I have. Good luck and let us know how it goes.
