Ithaka at sub 0.5ohm

[souroull]

Hi guys,

I used the Ithaka for the first time with 2 coils made from the pre-made wires it came with (not crossed). Vapor production was underwhelming, so i got me wire stash out and made 2 x 1ohm coils (1inch 0.17mm kanthal each) and put the sucker together at 0.5ohm.

Vapor production is much better, but i find myself needing more. How much lower can i safely go and what configuration is ideal?

Also, i noticed that it takes more power for the ithaka to produce the amount of vapor the ody did, does that sound right?
A 0.7 - 0.8ohm dual coil on the ody produced just as much, if not more vapor than the 2 x 1ohm paraller coils @ 0.5 ohm on the ithaka.

Using it on the GGTS and CGR18650CH panasonics.

With this batteries you can handle a coil resistance till 0.42 Ohms not lower!!!

Try to cross the coils like bishope do on his videos!

 

[justinred]

Lower ohms does not equate to better vapor production.

 

[Xylocaine]

Yes lower resistance does not instantly translate into greater vapor production. There are several factors that can be involved like the VG content of your e-Liquid. Wicking can also be a problem at lower resistances (I have an iGo-L with a 2 strand wick but pressing the button for more than 3 seconds turns the silica on the coil white @ 0.8 ohms). Sometimes I notice as well that a bigger hit/longer inhale produces less vapor then a shorter quick one. Also air flow is a huge part of all this - I'm afraid I do not as of yet own an Ithika but there are a lot of factors that go into vapor production.

 

[souroull]

Well, lower resistance translates to more power and thus heat on a mechanical mod, which should theoretically translate to more liquid being vaporized, which should mean more vapor... no? what am i missing here ?

My liquid is a third VG, and air control on the ithaka doesn't really change much in terms of vapor production.

Wicking was a problem on the ody sometimes, but it really isn't on the Ithaka, since it practically doubles the liquid supply on the coils vs the ody.

Sounds like your airflow around the coil is the problem. Put the coils in a x config and you will get,more vapor with more ohms

I agree. Try the x. And make sure ur battery handles the ampere because I think the c series might be limited? Not sure. Check its c rating.

if you want the biggest vapor from a single coil then do this sour:

Make a single coil and put it diagonal. Connect wires as usual. Then put again diagonal but on the empty channels another wick without coil. Put wicks on channels and do the rest as you do them now

 

[souroull]

Thanks for the suggestions, i'll try X config with 1 coil on each wick tomorrow

Θαναση, i want the most vapor and throat hit, coils and wicks dont matter. What's the best combo to achieve that? I can do 2 single coils, 2 dual coils... you name it. I got 0.15, 0.16 , 0.17 , 0.20 resistance wires... can do I, / , X config with the wicks.... hell i can even do W if i have to haha.

 

[imeothanasis]

wait, W is the best sour ahahahaha

ok, the best combo to my opinion for dual coil setup is the X style with 1 coil on each wick

 

[RiverNut]

Two 34 gauge coils at 2 ohms each in an X config

 

[fright88]

I am slightly lower then River with 2 1.8 ohm coils or .9 ohms. used the x method and it was hands down better then having the wicks run parallel. I basically followed Scott's video (igetcha69)

 

[souroull]

Ok, fair enough X it is, as soon as this tank is up.

Now, let's put some more things on the table. How does wire length and thickness affect everything? (assuming the end result would always equate to the same resistance value).


For the sake of argument, 2 wicks running 2 single coils running around 0.6 ohm would roughly be achieved by the following:

(2xsingle coils)

1 1/4 inches of 0.15mm
1 3/4 inches of 0.16mm
2 inches of 0.17mm
2 3/4 inches of 0.20mm

Alternatively, if more wire is better, the lengths above can be quarupled if each wick had a dual coil on it, so would any of the below make even more sense?

(2x dual coils)

5 inches of 0.15mm
7 inches of 0.16mm
8 inches of 0.17mm
11 inches of 0.20mm

Would probably need days to test all 8 combinations, so what works best in theory so that i can narrow things down?

Hi Sour, I see your doing some research so I wont rob you of the experience you are about to learn. if you need a hand with anything feel free to hit me up.

oh please feel free, i've done my fair share of fiddling around with coils and i'm having a hard time doing one/week right now ))))

 

[Blix]

IMO after dabbling with my 1.2ohm ready-made wires making a 0.6 ohm dual coil, I'd say putting the coils in a X with a wick in-between is crucial. You need to get that juice to the coils! Lots of it.

if you want I'll take you under my wing hit me up on OOvooo or Skype.

 

[BmoreJeff]

how do you fit dual coils on one wick? is this something you have tried? so your saying you have a total of 4 coils in ithaka with this 2x dual coil setup with just 2 wicks?

 

[BmoreJeff]

i sport a dual coil X setup at .8 ohm and i think its perfect. if you want more vapor i would get a higher vg content in your liquid. the more vg the more vapor, the more pg the stronger the throat hit. but i have 100% vg's that vape hit better than PG's. and the lower the resistance does not mean more power, think lower reisistance=more heat. your power stays constant (whatever your battery's output is, its the coils ability to "resist" the voltage which creates the heat, the thicker the wire the better ability it has to handle your voltage and the thinner it is the less ability it has which in turn generates the heat

Having 28,30,32,34,36 awg resistance wire on hand. First off as mentioned the wider the wire the tougher it is, but...it's slower to heat up. The thinner wire heats up very fast but may not last as long. And then there is the question of how long do you want the wire to be, thicker is longer, thin is shorter.
Thickness of the wick effects the juice content and the length of your coil.
Personally I try to match my wick to my coil. Thicker wick holds more juice for a hotter coil. A thinner wick with the same coil will produce even more heat due to the presence of less juice.
I've been experimenting with this since the Ody, and still change up regularly, just because I can.
One thing that I've tried that I would like to share is varying the 2 wick thicknesses to achieve a hot but moist vape, 1 thicker, and 1 thinner.
