Alright so I'm an experienced builder with rdas not so much rbas I put a standard 10 wrap 24g kanthal dual coil in my tfv8 and it's running crazy volts. Like at 60w I'm around 5.8v. I threaded another rda on go see if it was my mod no it read right. So I checked build to see maybe if I had leads touching. Nope not that either. Alright I tear it about pull 510 pins and clean all with hot soapy water and a tooth brush. Not fixing the problem idk what to do

Check to make sure you aren't touching the sides of the RBA deck. Sounds like there might be contact there. The RBA on the TFV8 isn't very large and I can't imagine it could fit a 10 wrap 24 gauge. Try a smaller wrap and wire just to see if that changes the voltage.
If you get the same build on an rda and its only pushing 4v, there is something wrong with your rda or rda build. The tank is pushing the proper voltage. So it is absolutely the solid build/atty.
Dry hit is due to wicking or overpowering. Only explaination. Ever.
What does your ohm meter say for your rda and for your tank with the same build for resistance?

In theory, if he had contact with the chamber/rba deck, his resistance would decrease, thereby decreasing the voltage necessary. Contact in his rda would possibly explain why it pushes less voltage than the tank.
Ive done this build a thousand times and have gotten 4v consistently. So if I've had 6 or 7 incorrect rdas then yeah I'd agree. I've built in this rba before with the same wicking as always. So I'm positive it's not a wicking issue. I'm not a noob I've been building for a long time I know what to expect out of coils and this is not right
5.5 wrap 20g coils are .24ohm each (so .12 for dual)
These should take 3.46v to push them 100w. And you are in the ballpark with the 3.3 on twisted messes. So that is a good build.
The tfv8 same build is pushing 6.1v. Which means tour resistance HAS to be .37 ohms. Which means you have a connection issue ie a loose connection or a damaged wire.
But the tfv8 is not to blame. Not at all. Because on your 10 wrap 24g coil tfv8 setup it does exactly what ohms law says it will do. Just like your twisted messes build is a good build. Because it does what ohm's law says it would do.
10 wrap 24g coils are .98 ohms, so .49 ohm dual coil. They require 5.42 volts pushing 60 watts. Your tfv8 build is right in this ballpark. Your "1000's of builds" in rda's that push 60w with only 4v are FUCKED UP!!!!! Every last one of them. Short of some kind. Not one single other explaination. "Experienced builder" who can't even tell me what resistance his build is at.
The tfv8 is right in one instance, wrong in another. Same goes for your rda builds.
The only constant is the builder. And this is where the problem lies. Do not build on a mech. You WILL blow your fucking face off.

Just to remind you of your initial inquiry.
The answer to the question of why your .5 ohm build needs 5.8v to push 60w is ....... and i know you love this phrase.....
OHM'S LAW
@Tfrazier just noticed this is your first post on VU. Welcome. Please be safe. Learn ohm's law. And I am only trying to help prevent you from blowing up your face with a bad build. Study up. There are plenty of helpful people on here. Please heed their advice more than you wanted to accept mine. Safety is not automatic in rebuilding. Please realize you do not know as much as you think you do about building. Come into building humbly. Or your batteries might "humble" you.
