Re: 1.6 vs 1.7 rockers
As a matter of fact, the valves dont float even up to 6500rpm. I ran 13.45 at 105 with a good bit of tuning left to do. Ive got triple valve springs and thats about all i know about em. What is the formula for determining how the lift will change with the change in rocker ratio?
