I noticed something on Judge's porting pics, there is a common feature: as for the long-radius side of the port inside the port tunnel, it ran pretty much straight from the entry of the port tunnel to near the ram, then make a sharp skateboard ram up and into chamber.

I noticed this on all of his porting posted. I wonder why and what are the reasons behind that? Why not have a more gradual transition like the factory, a gradual angle-change to guide the air/fuel mixture into the chamber?





thank you Judge,



Regards,



your good student

 

Is a style of porting that has created some serious VE...

 

He posted that is from testing the standerd design to one he uses now.

He was able to carry HP farther into the RPM range while the other had a peak area. If I recall correctly....somewhere in older threads.

 

huh never noticed this I must review my pics. do you have pics of other peoples porting for direct compairison?

 

ito's ports do look quite a bit differnt then others, but i never quite new why

 

wait a minute, I spent all night re-read all of Ito's posts, I can find he mentioned that anywhere, god damn it...over 55 pages of them......



Ito san, you got mail.



thanks
