Has anyone ever done this to there throttle body? Porting Polishing knife edged? How about are Manifold. Has anyone done the porting and polishing with them? Thanks laters Mikal

 

i did the throttle body bore, knife edged the butterfly, ground down the shaft, flattened the bolts, also smoothed out the leading edge of TB bore where it fits into short IC hose, and the leading edge(s) of IC elbows.

it cannot hurt!
