Re: Roller rocker issue
Re: Roller rocker issue
Small lift in cam and high ratio rockers vs. high lift cam and low ratio rockers
Some thinking related to issue.
- There are limitatios for cam ramp and lift that can be achieved there. One reason for rockers to have ratio higher than 1
- Cam ramps comes "faster" so actual time when valve is open is higher with high ratio.
- When ratio is higher than 1, lifters and pushrod move less with same valve lift so softer valvesprings are ok.
There are some reason I come up and there are probaply many more !!
