Trust Your Ears
Posted: March 1, 2013 | Tag:
For years I’ve “synchronized” the running of my engines by ear, letting them settle into that “mmmm … mmmm … mmmm” that lets me hear they’re running at equal rpm. Because I have older gauges with less-specific markings, I can look at the tachs and generally verify what I’m hearing. A friend is trying to convince me to get digital gauges with an engine synchronizer, telling me I’ll greatly increase my fuel efficiency and engine longevity. Is the cash outlay worth it?
I still have a rotary-dial cellphone, so I may not be the best person to ask about moving into the 21st century. However, I, like you, subscribe to the “if it sounds happy, it is happy” version of synchronization. In using newer tachs for verification of my hearing, I find that I’m rarely off more than 50-75 rpm. I don’t know if I’d spend the money until I had to wear conch shells for hearing aids.
