There are several different ways to look at this...
1. You are drilling up, ask yourself, have you ever seen anything fall up? Nor have I
2. The turbo is designed to see temps of over 1200 on a regular basis, do you think some small cast iron (read soft) shavings are going to hurt it moving thru at idle speeds?
The point is, your drilling up, and if you drill once and only once then 99.9% of the shavings will fall in your eyes, down your shirt and into your nose (those hurt A LOT!). Anything that does defi gravity and fall up will blow right past the exhaust wheel at idle and out the tail pipe.
No disrespect meant if any is taken.
