Dremmel crazy
Sooo I bought a dremmel the other day and had some time on my hands this morning so I decided to port my throttle body a little bit...
Super simple to do. I used a tungsten cutting bit to remove the majority of the material then a 120 grit flap wheel to smooth everything out. I know it's probably not as effective nor pretty as a CNC ported piece, but I don't have a CNC machine in my garage and this alone was enought to make me happy. Does anyone have any tips for home porting the intake manifold? Is it something best left for a pro to do? Just curious

You need to polish out the scratches use 1000 grit and polishing compound you want smooth air flow.

Although it seems simple enough you have to be careful. If you remove material near the blade, you are going to have issues getting it to run well.

Porting involves opening-up the size of the throttle body and / or the intake manifold that mates with the throttle bodies. Theoretically, this should allow more air or air-fuel mixture into the motor and yield more power. Porting is usually performed along with polishing some of these surfaces to smooth out the flow. Also, important is matching the opening of the manifold to the base of the throttle body ( or carburetor in the old days) and the gaskets to improve flow through the complete system.
Does this explanation make sense?
One must be careful not to screw-up components in the throttle body and their fit. Porting and polishing used to be a good way to make more power in the old days with carburetors and the poor match of component sizes between gaskets, manifolds, and carburetors. Not certain this is as helpful a procedure as it was in those days.
