So I decided to be brave and bore out my Taifun's air holes, some crazy vapour from this RTA now!
Excellent
Have a spare GT here that I'm playing with at mo - what mm bit did you use to take it out to ?
I heard a comment about drilling out clones and possibly exposing brass under the surface metal. Is there a reason you wouldn't want to Cape through brass? I believe I also heard that some brass contains lead for easier machining. Could that be the reason? Any thoughts or comments. I have an hcigar Tai fun GT and thought about opening up the airflow until I heard about the brass.
