Resonance and Reverberation: The Physics of High-Performance Exhausts High-frequency sounds, such as those produced by a high-revving engine, have more vibrations per second, producing a sharp, high-pitched sound Low-frequency sounds, such as the deep rumble of a large V8 engine, have fewer vibrations per second and produce a more resonant, throaty sound
What makes an old V8 lope VS a new rumble? : r cars - Reddit Lope is caused by valve overlap, where both the intake and exhaust valves are open at the same time This is caused by running longer duration, where you hold a valve open for longer, either to get more air in or to get more out
What creates the loud rumble of 1960s muscle cars? Well, with a standard exhaust system, the V8’s had a much more mellow rumble compared to a straight 6 A V8 will still give you that sound but not a V6 as much, and certainly not a 4 cyl
What is it about the engine is of old muscle cars that make . . . - Reddit Modern ECUs fuel management systems combined with a less aggressive camshaft allows for more 'civilized' and economical low rpm performance while still being able to perform higher up in the revs through basically complete control over timing and fueling
ELI5: Why do some Sports Supercar engines “whine” while . . . - Reddit There are many reasons why, but one of the most important factors in an engine's sound is how evenly the exhaust pulses reach the tailpipes Evenly spaced exhaust pulses tend to result in higher-pitched, smoother sound
How to Make Your Exhaust Rumble - It Still Runs Your vehicle's exhaust sound profile is a direct result of the engine and exhaust components The deep rumbling tone of an exhaust is typically characteristic of a large engine More volume of gas produced by multiple high-volume cylinders will provide the basis for a deep rumbling exhaust
High Pitched Whine - Ford Raptor Forum Some 2017-2022 Ford and Lincoln vehicles equipped with a 10R60 10R80 10R80 MHT transmission may exhibit a whine noise at idle and or while driving This may be identified as coming from the bellhousing and the front of the transmission fluid pan
Exhaust Noise Repair: Understanding Rumbles, Roars, and Rattles Common Causes: Rattling sounds usually indicate loose components within the exhaust system, such as a loose heat shield, exhaust pipe, or muffler Sometimes, it could be due to worn-out hangers that are no longer securing the exhaust system properly
