DIY porting Q
now i like to do things myself so i am thinking about porting my N/A seeing it went splah! on me. But how do you keep the housing from developing ridges in the surface?
through the power of PC paint, this is what i am talking about. I know on most any metal i have grinded, the heat and pressure, etc will push the metal up a bit. How can i avoid this? (spare me the "pay someone to do it" comments)
Just a concern.

i understand what you are talking about however i have never heard of it being a problem. i have ported many engines and never noticed any ill effects. you could try to keep the housing cool while you grind it by running water on it. you could also lap the housing after you do the porting to remove any raised area but you can only lap post 85 housings very lightly. when you are finished porting you can check the flatness around the port by using a straight edge and a feeler gauge.

generaly when you cut your ports you put a SMALL chamfer where the port enters the engine to remove the raised area or worse case is use a very fine flat sharpening stone to remove the raised area and make it flat.
