I don't know any answers to anything. I don't even know how a car works. There's something about combustion chamber, and the mixture of gas and air does something to rotate the crank. I know there's an exhaust and intake and the headers and the latter are made in a way that there's an equal distance from each cylinder or something. I know that Ross' ride is rice and slow and I know that my tach with a shift light is essential for my car's performance
