Lock This - Hijacked And Went To Hell.

Question is

How would 12 Watts feel on a 0.8 ohm paracoil (essentially a dual coil) versus a standard 1.3 ohm microcoil

Same power but totally different coil.

I once asked people on ECF in my early days whats the difference vaping a 1.8 ohm stock Kanger coil versus a 2.2 stock Kanger coil at the same power of say 8 Watts. The one has more curent and less voltage but the power is the same. I never could get my head fully around that.

Arguably the one coil has more mass since it has more wire, so would heat up slower at the same power. I.e. Not an instant vaporisation, but the more contact area would maybe mean more flavour when it gets going.

8W on both the 1.8 and 2.2 - if they were both micro's... would be slower to get the 2.2 "up to speed".
Once it hits that speed though, its gonna be able to maintain that for longer than the 1.8 without setting off a bomb...

The flavour difference will be noticable, as one will burn hotter than the other.
The battery life will be different, as one will draw more volts than the other.
One will give denser vapour than the other, as it is vaporizing more liquid with its higher heat (if wicked to performance!)
You would end up wicking them differently.

Once you change the coil designs though, im sure there are pros out there than make a 1.8 and 2.2 indistinguishable from each other at same wattage, with different coiling designs and wicking techniques.

I get what you saying and there sure are lots of variables involved.

But i always thought that the lower resistance coil would heat up faster? At least thats what I witness in practice on my side.

@WHeunis If you want a damn sexy regulated mod!

If you feel you absolutely must vape @12W, and want a consistent delivery from the battery ALL THE WAY DOWN to its empty point of 3.2V safe discharge limit...

0.8 ohm coil recommended.
Running 12.5W @3.2V with 3.9A

Most svds won't fire a 0.8 ohm coil. Mine only fires from 1.3ohms and up. Some have reported firing coils lower than 1 ohm. But in the specs 1.3 ohms is the lowest ohms the svd was designed to fire.

 

[MarkK]

mine will not fire lower then 1.2

I had them turned around, you are correct.
Smaller surface, etc.

I need to check if my SVD will fire at 0.8 ohms - at 12 Watts
Then to see what impact this has on power sag when the batt gets to around 3.8

If all works then @WHeunis has helped me big time!

Worth a shot

Not sure when I will try but will let you all know

Use the safest batteries possible!
I do not recommend anyone experiment on unsafe batteries! VTC4 or VTC5!

i dont think you really have to worry about this cause at 15w, at which the SVD is rated, and a 0.15 coil you will only require a battery that is safe at 10a and then again are we really considering sub ohming with a SVD

 

[WHeunis]

Seeing lots of anecdotal evidence of SVD firing a 0.8 coil, but could only find ACTUAL evidence for 0.9.

Is this not just Getting an ohm reading from a device, or is is this the device actually firing the atty at that build.

Some devices that have ohm readers as a feature, eg if you attached a 0.5 build to that device it would read the ohms, not all devices built in ohm readers are acurate but will still give you a reading, but this does not mean that it will fire the build

edit - I still double check my builds on both an ohm reader and my elec. mod just to be sure before firing, and even though my sigelei only fires 0.5 it still reads my 0.2 builds

[WHeunis]

Now from what I can gather, it seems that dualcoil is where most guys get the SVD to fire subohm'd

 

[Al3x]

Very informative, this was one of the main reasons I went with the VTR and not the SVD when I had my innokin phase.

 

[Andre]

The SVD is limited to 15W (in practice from what I have read actually closer to max 13W), so whatever resistance coil you put in there the vape will be as for a coil around 1.2 ohms.
The VTR is a case in point, it fires at quite low ohms (around 0.5 I think), but the power limit negates that.

Agree, the VTR fires 0.5 but due to the wattage limitations really defeats the purpose of building a 0.5ohm that's was my "excuse" for another upgrade, and then another

So true.
I only intend to use it around 10-13W for a 1.5-2 Ohm use. (These were my sweet spots when trying out my friend's kits)

Would still be nice to see if a 0.8 coil would get @Silver a better experience for his required 12W vape.

 

[johan]

@WHeunis, you raise a good point

I always thought the SVD shouldnt have a resistance lower than about 1.2 ohms, because there is no point, you cant get more power out of it than the 15 Watts its limited to

But come to think of it, if i build a 0.8 ohm coil as you suggest, i may be able to supply 12 Watts for longer.

To build a 0.8 ohmer to my flavour preference i will have to make a paracoil because a normal coil will have too few wraps. (Edit - personally i dont like going thicker to 26g)

I will try that some time and let you know what I found

@BhavZ , @Andre, @johan, what do you guys think of this? Interesting... Building a lower ohm coil not for more power but for more sustainability at lower power

With all due respect, I am not going to comment here as 99% of all vapers seems too lazy to do simple mathematical equations (Grade 9 physics) and choose to rather make unsubstantiated statements based on ego and/or thumb sucking; i.e some people apparently gets over-unity power from a batteries by using super conductive "slap" chips with or without salt & vinegar, ketchup etc. I am not going to be drawn in an argument with vapers who already defeated the basic laws of physics.

 

[Riaz]

i had a SVD and it fired 0.8ohm coils without a problem- that is twisted 30g kanthal, not dual coils
