Okay, I’ll admit it, I’m a total sucker for a great engine note. Working on cars all day, you hear a lot of them, but some just stick with you. Lately, I’ve been trying to pin down what makes a sound truly satisfying. Is it the raw, high-pitched scream of a V10 at full chat, or that deep, lazy burble from a big V8 at idle? Then there’s the modern magic of a turbo inline-six, with that distinctive whistle as it builds boost. They all have their own character. For the guys who love restoration and getting their hands dirty on engines, what’s the one sound that never gets old for you? I’m curious what everyone else finds the most thrilling to listen to.
