Does Vacuum Increase With Rpm at Nate Justine blog

Does Vacuum Increase With Rpm. If you nurse the speed up gradually, with light throttle in neutral, the vacuum stays high. Any leak aft throttle plate will not cause an increase in overall engine vacuum. Learn how vacuum advance works with initial and mechanical advance to optimize ignition timing for street engines. Now, switch the vacuum advance to a direct source of vacuum and again check the idle rpm? Under light or no load conditions, engine vacuum may increase with rpm due to the increased speed of the pistons and the resulting. On most engines, accelerate to around 2000 rpm and then quickly. We'll bet money the rpm. Typically when idle vacuum increases off idle its a sign that the carb is way rich at idle and/or possibly the valve guides have way too. Plug the vacuum advance into a ported vacuum source and check the idle rpm. If it is pulling vacuum, a leak will only decrease vacuum. Vacuum varies with load, not rpm.
