I have to read this in years and it's a damn shame. There is so much quality information in there I had my wife print off the entire 51 pages so I can makes notes and reference it.

I love the fact that RB explains why R/S ratio DOES make a difference, especially in induction limited applications. But IMO it makes a difference in how you select your timing events. A higher R/S ratio affects when the piston reaches max velocity and how it moves around not only BDC but TDC.

If anyone wants to gain a better understanding of cam timing, you can't beat this article.

Reading between the lines you can start to realize why there is a benefit to more agressive lobe profiles, and power output is not at the top of the list.

Thanks for the link Wyr. Great stuff.
