don't give me any ideas LOLYeah, this whole thread is a "get off my lawn" rant. It's been entertaining watching it shift from "those loud cars suck!" to "these loud cars are awesome!"
They're all loud and annoying to people who like peace and quiet and dream of having decibel triggered/oriented turret-mounted RPG on top of the house.

It's all about converting potential (chemical) energy to kinetic energy (mechanical, heat and sound are all kinetic):
You should see how much forward thrust John Force got with his headers when he experimented sweeping them back instead of up. Now there is a limit on swept back headers.It's all about converting potential (chemical) energy to kinetic energy (mechanical, heat and sound are all kinetic):
1. movement of the piston - that's really the one we want and that causes vehicle movement
2. movement of exhaust gas (including heat and ejection) - kind of wasted energy but necessary for 1.
3. movement of "static" motor parts (vibration and heat), and surrounding air - this is where sound is from - kind of wasted energy but necessary for 1.
So noise is wasted energy, but "directing" that energy to piston movement instead isn't really possible. Potential energy gets converted into the various forms of kinetic energy as it pleases with engineers having limited contol over how much of each kind. But yes noise involves a very small portion of overall energy. Moving eardrums as opposed to tons of steel.
Tell me about it. I build an RD400 Cafe Racer with Boyesen reeds, chambers, trimmed guards, clip ons and rear sets. Solo seat and air suspension. Great race bike, but I commuted on it as well. Cost me more in fines than it did to build...It was!! The ear splitting sound of a 750cc two stroke and the smell of Bel-Ray oil is not easily forgotten
