Like you, I recall my N/A being quieter than a Prius when coasting... even after track days and dozens of dragon runs.

This has been one of those things I have just chalked up as a 'difference' between the two.... but perhaps I should look back into it. I know Jane Bridges ate wheel bearings like cookies on her SRT...
I was amazed at the freewheeling ability of the manual boxed na, it would start rolling when I thought I was on the flat. It just started to creep with the car not in gear no brakes. It just rolled along very slowly with just a slight imperceptible slope.
