Taifun Gs And Cobra Genesis (19mm Dia. Or Smaller Rbas)

[JakesSA]

Being the proud owner of a VTR, I'd like to start exploring a bit of low ohm rba vaping.

The VTR has an atomiser 'protection ring' on it which I want to keep intact for the time being. I also like the form factor of the side mount atomiser and having said that, I started looking for rbas at 19mm or smaller diameter which fist inside the 'protection ring'.

So far I have found two candidates, the Cobra Genesis style rba and the Taifun GS.
Anyone have experience with these, perhaps know where they can be found locally or other options?

 

[Andre]

No knowledge on that unfortunately, @JakesSA. You do know, whatever the resistance of your coil you will be limited to 15 W by the VTR? Effectively, you will be vaping a 1.2 ohms coil, even if you built a 0.8 ohms one.

 

[ET]

just mod that vtr and put something nice on there instead

 

[Reinvanhardt]

This here's Smoktech Scar should also work, not a bad looking dripper although I would agree that circumcising that son would be a marvellous idea. I have no experience with the other compatible atties.

 

[Reinvanhardt]

Oh and most drippers like the Igo-L should work if you have a long enough drip tip. Might look strange though.

 

[JakesSA]

Thanks for that, I think for a dripper I'll rather get a large size and use the extension tube. The rba must preferably be a tank type for convenience.

The 15w does limit the 'work' done by the device so effectively it would take a 1/4 unit of time longer to get the same 'work' done as, for example, a 20w output.

My understanding has always been that the device is limited in both Watts and Amps and can go no higher than those limits. Otherwise why would they bring out 20 and 30 W devices.

 

[JakesSA]

You are 100% correct.
What I have to contend with, given the 15 watt limit, is a 2 second inhale vs. a 1 second inhale on a 30 watt device, for similar effect.

 

[Reinvanhardt]

I don't know... In terms of joules per second, per second that makes sense but it is certainly not the case. 20 watts for 1 second does not equal 10w for 2 seconds. Diminishing current due to time lapse? I'm going to study the relationship between volts, watts, amps and resistance now. Good question.

 

[JakesSA]

Hypothetically, watt is a unit of work which is then carried out over a unit of time. I am pretty sure its not quite that simple in real life vaping though and by no means am I indicating that, with patience, a 15w is just as good as a 30w.

 

[Andre]

Well, from personal experience (whilst we wait for the science by @Reinvanhardt), you might have something there. Found on tanks I really have to take a long toot to get some satisfaction as compared to the Reo where a short toot is sufficient. But going sub-ohm coil on the VTR does not make this better or a shorter toot, you still have to toot as if on a 1.2 ohm coil, if that makes sense.

 

[ShaneW]

Perhaps because it would take the coil a little bit of time, depending on the coil, to heat up and get to it's full delivery.

But if the coil was completely heated, I would say 2 secs of 10W should equal 1sec of 20W.

Could be wrong but that's my understanding of it...

 

[ShaneW]

And the higher the wattage the quicker the coil will heat up

 

[Andre]

And the higher the wattage the quicker the coil will heat up

Which translates to better flavour, vapour and throat hit - which is not gettable on the lower W, not matter how long you toot?

Makes 100% sense @Matthee.

Yeah @ShaneW that's what I meant by diminishing current over time, thus a constant slight temperature loss. So theoretically it will never be equal. I stand to be corrected.

Yip, on lower wattages, the coil wouldn't able to get to it's max heat as it's covered by juice that's cooling it and air passing over it.

In higher wattage systems, it has the power to 'punch' through that and deliver the needed heat

 

[JakesSA]

A small irony that the unit watt is named after James Watt who in turn was very much into steam engines ..

Yes, I think you will get diminishing returns, as the liquid vapourises and is no longer in contact with the coil it cannot be heated further.

Don't quite get the diminishing current over time though?

perhaps this link will help with understanding

Just remember that the only way current can diminish is if
1. The resistance of the coil changes to a higher ohmage
2. The battery voltage drops
3. The power setting on the mod(if electronic) is changed, which essentially just changes the voltage or resistance(internal resistance, not coil)

This is the fundamentals of ohms law

 

[Andre]

The most important thing is that you enjoy your VTR and whichever RBA you get. Building your own coils is awesome.

 

[JakesSA]

Err .. yes .. seems the steam engine got derailed there for a bit. Thanks for the input gentlemen.

Yes you are correct I should have said diminished joules.

@JakesSA I am loving my modded IGO-w3 dripper on the VTR, I'm also finding the extension piece is actually really cool for me. I was going to cut the ring, but then after using a dripper on this thing I am re-thinking that idea. Even the Kayfun looks pretty sweet sitting up top

I just wish I had some good juice atm

 

[Andre]

No, not at all. These sort of discussion are more than welcome. The more we understand, the better we are equipped for vaping and answering questions on vaping. Of course, not everyone's cup of tea, but fortunately participation is not mandatory.

 

[Reinvanhardt]

If you want to leave the VTR unmodified I would go for the Cobra in terms of a tank style RBA. It's locally available at Vapesa.co.za. The Taifun GS also looks cool but you'll have to get that from Fast Tech.
