The lastest issue of MazdaSport Magazine is on the newsstands at Barnes and Noble. In the previous issue, I wrote about porting theory. In this issue, it is porting in practice. Article on pages 76-79. This is Volume 3, Issue 3 of MazdaSport (formerly Miata Magazine), which is the official publication of Mazda NA. If you can't find it on the newsstand, you can order a subscription of back copies from http://www.mazdasportonline.com.

 

I got one issue a while back. I guess it was the one about porting theory. It described the different types of ports and such.

Can you write an article where you have dyno before/afters on your 5/6th port sleeves?

 

nice article i read both of them...helped to understand ports even better...
