This is one of the best videos I've seen about port matching and polishing cylinder heads on youtube. Great work, and thank you very much :)

Will go later on and do my Punto GT head

That is so cool.....thank you very much. I try to do the best I can.

don't make intake runners that smooth. Get rid of the seam line, yes, but some texture has been proven to help the atomization of fuel for more power. It isn't always about getting the most flow on the flow bench... you want well mixed, high velocity air. Big smooth ports allow higher rpm but run flat. Port/polish is 1960s thinking, and is only "dyno proven" because the gains from matching the ports are more than the losses from polishing the runner,,

I agree with you 100%...if this were a carb engine. This is fuel injected at 60 psi with high perf injectors. The fuel will be atomized at roughly 55 carbon pentane molecules per million and mixed with just air coming through the intake. The only thing going down the runners will be air mixed with fuel vapor so no additonal atomization needed. New engines use plastic plenums that are extremely smooth and heads manufactured polished. I could go with a carb but that is 1930's thinking.

@CoolCarsHotGuitars you just shut down that guy big time nice comment!

[CoolCarsHotGuitars]

That was not my intent because I respect everyone's opinion. However, it should have been obvious from the video the engine is fuel injected. The atomization of fuel is a science I studied for quite some time so I know what will work (or not) and why. What was high tech in the 60's still works today because the methods of measurement have become more accurate and reliable. Just know what you are talking about before making a blanket statment. Knowing and knowing why are 2 different things.

Awesome! Good luck and have fun!

Thanks - great video. I am up to port my E7TE heads so this was useful for the basic port matching!

I'm not a genius...just sharing information that is already available....thanks!
