Intake noise on cold startup
Now that I've got a few hundred miles on the clock, I've noticed that when I first start it from cold in the morning, there is a distinctly different sound from the intake. It's a sort of hollow, "open throated" sort of noise, sounding rather like a leak, and it goes away abruptly after about 20 seconds or so.
I assume it's because the system is opening a more direct intake tract which bypasses the muffling of the air filter assembly, but only when the engine is below a certain temperature. (Though here in Texas it's never going to be "stone cold" - our current overnight lows are in the mid-70's.) Curious, and I thought worthy of a comment. Has anyone else noticed this behaviour? |
I noticed the same thing this weekend, and I too am in Texas. Not sure Texas has anything to do with it though.
I'll be interested to see if anyone else has heard this. |
I love that sound! I always start with the door open these days to hear it! :D For me it's a kind of air rush sound with the engine gulping for air. Sounds quite sexy to me, like a V8 drawing breath or something - not like a leak. Doesn't last more than a few seconds though.

eccles isn't that just the cold start assist? My second and thrid gen would stay up at about 3k. I've noticed that the 8 just revs to 2k.
