Eli I saw you at winking lizards monday night. True story.
Back on topic, Powers makes an interesting idea, of opening the intake much more, so that more air can be forced, since we do not have to guide it in like a NA car. Are there some equations out there that can help you get an idea of how far to go, or is it more or less trial an error. Because to have an effective air pump, you need to suck in a much as you can, without forceing any back out, and this is really impossible in a real situation, but the idea is to get as close to this ideal value as possible. Here is another thing I keep reading about, and many people here it all the time, import head porting really isnt all that hyped up, this is mainly due to better desgins then most domestic stuff, I mean there is a reason imports are easy on fuel, they are more efficent, less energy wasted. So really with import heads there isnt as much changes that should be made? I guess for a mild *street* port you really just need to port match, and do minute abouts of porting to the intake, and a little more aggressive on the exhuast, and some polishing thrown in there. But for say a race port, do you go as far to start looking at cut aways of intake ports and figure out how they can be reshaped? What would be an ideal shape? Why? What would be an ideal exhuast port shape? Each motor is slightly differnt, but similar at the same time.
