Switched to Dual Titanium Coil – Great Flavour at First, But Then…?

[vapewarehouseau]

Hey everyone,
I recently switched out my old single coil setup for a dual coil made with titanium wire. Resistance went from 1.2Ω (single coil) to 1.4Ω (dual coil). Thought I'd share my early impressions and ask for some insight.
For the first ~100 puffs, the flavour was noticeably richer and smoother – I was actually really impressed. But not long after that, I started noticing a drop in vapour production. The flavour is still decent, but the clouds just aren’t hitting the same.
So now I’m wondering:

• Is this just how dual coils behave at this resistance?
• Could it be something to do with heat-up time or wicking?
• Or is 1.4Ω simply too high for a dual coil to really shine?

Would love to hear your thoughts or tips if you’ve used similar setups. I’m open to tweaking wattage, cotton, or even coil position if needed.
Cheers in advance!

Hey bud, cheers for sharing your experience — always good seeing folks tinker and explore new builds.

I haven’t dipped my hooves into titanium just yet, but it’s on my list. What I can speak to is coil resistance and airflow behavior, especially as a power vaper who rides low and fast — 0.1 to 0.15Ω is my personal sweet spot. Anything higher and I start to feel like I’m sipping soup through a straw.

At 1.4Ω on a dual coil, yeah, you're definitely in mellow territory. That heat-up time is going to be slower, and if your wicking or airflow isn’t dialed in perfectly, vapor production can suffer. Flavour hangs on for a bit — as you noticed — but the oomph tends to fade without the power to back it up.

If you’re open to experimenting, drop the resistance and give a lower-ohm setup a try. You might be surprised at the balance you can strike between flavour and cloud when you’re running coils that were built to kick — like the ones I make over at Old Goat Coils. Hand-wrapped with low-resistance performance in mind, perfect for single or dual setups if you like pushing your gear without frying it.

Give me a shout if you ever want to try something gnarlier. The Goat’s always mixing something up.

Hey mate, appreciate the detailed reply – love the energy!

Yeah, I figured 1.4Ω was leaning into the mellow side of town, and you nailed it with the “sipping soup through a straw” – that’s exactly how it started to feel after the first 100 puffs. Flavour stayed decent, but the hit just wasn’t there anymore.

I’ll definitely look into dropping the resistance. Been toying with the idea of going sub-ohm for a while now, just wasn’t sure how aggressive I wanted to go with titanium. Might even step away from Ti altogether for now and play around with kanthal or nichrome at lower ohms – seems like a better match for what I’m after.

And cheers for the heads up on Old Goat Coils – hadn’t heard of them before but sounds like something I should check out, especially if I start chasing clouds instead of just flavour. I might take you up on that gnarly offer soon.

Thanks again, legend!

where on earth did you find TI wire to make a coil?

and I really really hope that the set up is MTL, that does make it make sense.

and I would really really recommend playing with temp control on a TI coil.

temp control really makes a big difference, you need to adjust wattage AND temperature.

what I have found with SS316L coils is that the flavor falls off after a while due to the way the coil resistance changes as it heats up. that can also cause spitting.


so I am going to try and explain a little about why after a while the coil gives a different experience.

your temp control metals all have the same key properties, the resistance changes as the temperature increases.
so lets say you have a coil that is 028 Ohm when it is cold as you fire it the resistance chances a few drags later ion quick succession and your resistance reads 043 Ohm. now you put it down it cools and a fun process happens in the metal, called hardening, the structure of the metal changes slightly and with the next fire instead of going to 0.43 it goes to 0.46. eventually the coils will stabilize completely. only then is your coil burned in.

my recommendation is, start your TI coil much lower than where you want to end up at, and spend a lot more time tempering the coils.
red hot, air cool, red hot air cool and repeat that checking the resistance when cold and hot and making notes, when it has stabilized, then you have an idea of where your coil actually is and if you will enjoy vaping on it.

Hey, thanks for the detailed explanation – really appreciate you taking the time to break it down!

As for finding titanium wire, I actually got it from a local vape shop that carries a variety of exotic wire materials. Wasn’t sure how well it’d perform, but figured I’d give it a shot for the flavour experience.

I was hoping the setup was MTL too, but ended up being more DL due to the dual coil and higher resistance. Still, I get what you’re saying – MTL would definitely make more sense with this kind of build.

I’ve heard a lot of great things about temp control with titanium, so I’ll definitely give that a go. Haven’t really dived into it too much, mostly stuck to wattage mode for now. I can see how adjusting both wattage and temperature could make a massive difference in the overall experience. Definitely worth the extra effort, especially for titanium coils.

Your explanation about SS316L and resistance change is super helpful. I hadn’t realised how much hardening and resistance change could impact the flavour, so I’ll be more mindful of that from now on. I’ll follow your advice on tempering the titanium coils as well – sounds like it’ll be a game-changer. I’ll take the time to properly break them in before finalising the setup.

Thanks again for all the insights – looking forward to experimenting and refining this build!

I have no idea how you can attempt to vape DL at that high resistance.


also be careful with that set up, if you were aiming MTL and put a salt based juice in there, with a resistance that high salts could turn into benzine gas. again its a COULD not a will. there is a lot of factors.
