Cars
Fast cars slow cars
Old cars new cars
Diesel powered
Gasoline powered
They have crankshafts
That powers the piston
The camshaft powers the valves
They have many cylinders
One to thirty cylinders
I like how they sound
Each engine sounds different
Which means each engine is unique
Like a Mazda 787B could have a nice rumble
Could also have a high pitch scream
A truck could have a nice rumble
Then you get the turbo spools
Same with a Toyota Supra
Twin turbo or
Single turbo could have a
Supercharger with a bug catcher
They can be built or bought
I would build my dream car
Not buy it
