You'll definitely need to upgrade your gear, and knowledge. There's a few routes that you can pursue for more vapor.
- The easiest route is to increase the Vg (vegetable glycerin) of your e-liquids. You can custom order the Pg/Vg ratio with most e-liquid vendors. Vg is what produces the vapor in e-liquids. Pg is a better flavor carrier and is somewhat responsible for throat hit. The concentration of nicotine is the biggest determinator of throat hit.
- Get a more advanced battery device. A regulated VV/VW mod will be the safer choice, as they have built-in protective circuitry to keep you out of trouble. They won't fire an atomizer if there's a short and will refuse to fire or shut down. You can increase the voltage (or wattage) output for a harder hit. You can use any rebuildable atomizer on a regulated mod, but can only build coils around 1.2 ohm or higher. Most regulated mods will not fire lower ohm than that as they see the low ohm as a short.
- A mechanical mod has no built-in protection. You'll have to rely on your knowledge and observation skills to keep yourself out of trouble. However, if you have the knowledge and observation skills to recognize a short, you can build a sub-ohm or micro-coil on a rebuildable atomizer for the largest clouds possible.
- A Kick is used in mechanical mods to regulate wattage and allow higher voltage output. It has its limits in how low of a coil it will fire, and also has protection circuitry like a regulated mod has. It essentually transforms a mechanical mod into a regulated mod.
I highly recommend that you educate yourself from the various subject matter in this link:

This.
Start with a regulated MOD of some kind before you explore the world of Mech MODs. They are safer and can perform the task you're looking for easily. I'm using the new Sigelei 20W (though my first MOD was the Innokin Cool Fire 1 - a GREAT first regulated MOD, though the wattage isn't variable but fixed at 8.5W) and I can attest that it will give you huge sums of vapor with a Kayfun, even at much higher atomizer resistances. I'm currently running 2 separate Kayfun 3.1 clones (Hcigar - take note that not all Kayfun clones are built equally), one at 1.7Ω, the other at 1.4Ω and I'm getting clouds of vapor that no clearomizer can dream of matching (even when used on a starter MOD like the Cool Fire 1). If a fixed 8.5W isn't what you seek, you can also look at the Cool Fire 2 which can be set from 7-12.5W via a mechanical ring (as opposed to a dial or buttons), or something like a Provari or iTaste MVP, but I'd go with a regulated MOD of some kind before moving to a Mech MOD. The learning curve is not nearly as steep, and it's a much safer way to move in to the world of MODs.
You can score a new Sigelei 20W and a high quality Kayfun clone for about $120. Get an ohm meter, some organic cotton, and kanthal for another $20-$30 total, and you can be on your way to a great vape for a decent cost in just a few days (it took me about 5 tries with building coils to start to get good ones)
