as far as a bigger coil with more metal. are we talking 24g/22g. and isnt the bigger coil with more metal going to drive my ohms donw and get the coil hotter faster?
I was thinking just add a wrap or two, but either way, no. Bringing the resistance down doesn't necessarily mean that the coil will heat up faster. This is only true if you take metal OUT of the coil to bring the resistance down. Say you were to take a wrap out of a build without changing anything else... ...that would bring the ohms down AND decrease the ramp-up. You could also go up in gauge and leave everything else the same to get a coil that has more resistance, but still heats up quicker. A 24g @ 2.5mm and 7 wraps will not heat up as quickly as a 28g @ 2.5mm and 7 wraps, even though the latter has a higher resistance.
If you add more metal, but the power level is the same, then the coil will always heat up slower. Whether you add a wrap or use thicker wire, it's the same amount of power heating up more metal. A fatter coil retains more heat, but takes longer to heat up. For example, at 100w for both, a dual 22g at .2 will heat up slower than a dual 26 at .3, but the 22g will get hotter overall. Even if you want to go by resistance and assume the same voltage is going to both (as it would on a mech), a dual 22g at .2 will still heat up slower than a dual 26g at .2, even though they both produce the same wattage because although 22g is more conductive than 26g, inch for inch, it also thus requires more length to hit the same resistance.
This is also why single coils heat up faster than duals and duals heat up faster than quads. A .2 single has half as much metal for the current to move across as a .2 dual. Hope that makes sense. I'm starting to go in circles, now.
The whole concept of decreasing ohms to speed up a coil is something that mech-users have to utilize because when you're using a mech, your voltage is fixed, so the resistance determines how much wattage you get. You have to strike a balance between resistance and surface area in order to get optimal performance at a fixed power level. With a regulated box, this approach is counterintuitive because you can adjust wattage to taste after the fact, resistance be damned.
