I have a set of s5 T2 rotors. there is a machined finnish on them would I affect the compression ratio, or ballance if I went over them with some 400 grit sandpaper and then polish them? I want to prevent carbon buildup. Is it a worthwhile mod? Thanks.

i polished up a set of s4 turbo rotors. i didnt really do much other than shine up the machined faces, so i dont think it changes the balance.
i dont have any way to tell if it did anything, but the engine did run really well

I use an angle grinder with a 3M abrasive impregnated bristle pad. Takes off the carbon without damaging the metal. Just don't go crazy with it. Mac carb cleaner also works great if you let the rotor soak in it overnight.

Factory balance is so far out I don't see how you could make it any worse anyhow...
Huh?? What are you talking about?
It's not "so far out of balance" in that they rev to 8k or 9krpm stock out of the box...

haha, good point.
not to mention it goes round and round instead of up/down.
the stock engines are grossly out of balance compared to any piston engine in production. Rotaries are just THAT much smoother.
