Ok so for those of us who do not have or can afford to make dyno runs to adjust our power valves.
Is there a guideline for how many turns or portions thereof that equates to X RPM?
For example:
.5 Turn is approx X RPM
1 turn is approximately X RPM?
1.5 Turns is approx X
Thanks for the real information on the PV Jerry, lots of great insights.
