Try thicker guage wire and less wraps bug...13 Wraps sounds like a thin ass wire or waay too many wraps for any wire...I got my Diablo clone to work now, well its not my piece of cake but its blowin tha cloudz.
13 wraps of 0,44mm V4a around 3mm at 0,38 ohms. On my serial Box, thats around 150 watts
No more leaking because of shitloads of cotton in there. Flavor is great but I really dont like to take 0,5 second hits.
This thing is totally made for cloud chasers imho, you can build some serious stuff on that deck...
With this setup the tank lasts for around 20 hits, ridiculous
Try a simple 24g (7 Wrap/2.5mm ID) Dual Coils...Should be great around 60w-70w and it will take up more of the chamber so it wont feel as airy and provide a better experience.
