Thoughts on Engine Sound at High RPM's (kinda long)

wstar

I guess it's subjective whether it sounds/feels like a problem. I'll grant you, to me it sounds like a beast of a machine rampaging out of control, but I guess that's what I expect from that many RPMs in a V6. Doing the math (3.7L V6, 4-cycle), at say 7,000 RPM that engine is exploding a 617cc ball of fuel/air mixture about 350 times per second in a tiny lightweight aluminum machine, and trying to capture rotational mechanical energy from the process. I'm sure some engineering could make it sound/feel sweeter, but c'mon what do you expect?

It never feels to me vibrationally like the engine is tearing itself apart though. It could be that the 7AT's torque convertor damps a lot of the vibration, so that we only get engine-mount vibrations and not transmission-mount vibrations, if everyone who notices this has a 6MT.
