There is no way you can detect an NVH difference between a timing belt and a timing chain from behind the wheel.
Any perceived difference in smoothness (assuming both are 60 deg V6s) will boil down to method of engine damping (active vs passive motor mounts, perhaps motor mount material and mounting points) and sound deadening.
Gonna agree to disagree on that -
In that NVH is noise vibration and harshness, many can hear, there exists a clear noise diff between the two actuation methods.
sometimes a pronounced diff - take a small block chevy and listen to the diff between a pete jackson gear drive and a jesel belt drive, even the "quiet" one.
Feeling it - perhaps, perhaps not.
Gear drive?
Gear drives make noise because they are straight cut gears.
Take an SBC with a timing chain and a Jesel belt drive and there is virtually no noise difference. Built both, heard both.
ree to disagree.
You will not feel or hear any timing chain noise from behind the wheel unless there is a problem.
A normally operating timing chain is not noisy.
Bottom line, any perceived smoothness of a Honda engine from inside of the car has nothing to do with it being a belt or chain that drives the cams.
There are several types of gear drives, straight and helical cut (helical cut being the "quiet" one I mentioned above)
A SBC with its short timing chain and path is the quietest example - engines like the ford 5.0 coyote with multiple feet of chains, sprockets, tensioners and guides all make more noise than a belt doing the same job.
Still agree to disagree.
