'Cuda vs Hellcat Sound Wars
I was listening to an episode of *****in' Rides recently and was amazed at the difference between the 1973 340 'Cuda and the 2015 Challenger Hellcat that they compared. The 'Cuda had been punched out to a 416 and the two cars received exhaust cutouts. But with the exhausts open or closed, it was unanimous, both to Dave Kindig and his cohort Kevdog (and to me as well), that that Cuda sounded like angels singing compared to the modern muscle.
So I 'm sitting here wondering: why? I know a lot about engines, but not so much about just what creates the harmonics of sound.
The two engines sounded different in a number of ways, with the Cuda sounding, as Dave put it, more "Gnarley." But another thing that stood out on the show confirms something I've thought about many times before:
Why is our modern HEMI so slow to return to idle when ya take your foot off the gas? What's going on with the fuel system that causes this?
IT SOUNDS ALMOST LIKE THE THROTTLE IS NOT BEING FULLY RELEASED.
