hf external wastegate
 

what do you guys use to cut a clean whole in hf mani to weld on a external wastegate? I got a tourch and could prolly get a plasma on it but i doubt theyed come out clean. hate to stand at a press drilling whole after consecutive whole in the mani. so whatya use thats clean and easy?

torch works good.

yeah, i figured it wouldnt be to clean and theres be alot of slag

Re: hf external wastegate
 

i did AbaZ's with the torch, if you know how to use it, slag aint too bad, and I took a carbide porting bit and cleaned the hole up a little.

That setup looks nuts on the HF. How does the audi wastegate flow?
