Learning about 7.3 Port/CC Swirl

Learning about combustion chamber swirl in the 7.3 Powerstroke.

This article helped me understand just how power is made in the combustion chamber through the fuel's burning characteristics in the head.

So all I get from that is pick your porter very, very carefully!

Flow without swirl on a street truck can be a bad thing. Once you get into the super high HP arena, there are other considerations and swirl may or may not be one of them.

True!

But for about 95% of us here on the board.....When and if we should ever consider getting a set of heads ported...
At least we'll have a basic understanding of just how the head works and who to listen to or ignore when it come time to shell out some frogskins.

Getting an education while holding a fistfull of cash can be a bad/expensive experience at times.

Re: Learning about 7.3 Port/CC Swirl

"If you look at a diesel from a performance standpoint, you canít disturb the swirl of the port or the piston design. The manufacturers of these engines have gone through countless hours and testing with equipment we only wish we could use in order to design the port and piston combination that makes their engines most effective."

I'm not sure I really agree with that statement.

Re: Learning about 7.3 Port/CC Swirl

used to be the quick answer was port and polish didn't do much dont waste your money etc...prob cause it was done wrong and hurt or did not improve performance.

now it seems it def does make a diff, if it is done right.
I saw an article in dp a while back where i think elite diesel was doing some head work and seeing some decent improvement.

Untill recently they put 0 time into anything other than getting it to run and longevity. Factory development gave us intake ports bent around pushrods. The newer stuff is MUCH better but there's always more room for improvement/failier.

Doesn't roll with anyone or tag along to be cool...
