So if you multiply torque (in pound-feet) by engine speed (in RPM) and divide the product by 5,252, RPM is converted to radians per second and you can get from torque to horsepower -- from pound-feet to foot-pounds per second..
Did it explode? Nope! You can still see it flying. Then what was that sound? It was a sonic boom. A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.
It is engine RPM which causes exhaust gas pulses at a certain frequency, exhaust gas flow speed, size of the exhaust pipe and length of the exhaust pipe etc etc etc. . . . . If the right conditions occur so does resonance and the sound booms. So the purpose of the resonator is to prevent resonance from happening.Specically, the resonator does this by momentarily storing exhaust pressure in the exhaust pipe. This occurs when a pressure pulse moves down the pipe. During the lull period before the next pressure pulse this pressure gets released rapidly.t is engine RPM which causes exhaust gas pulses at a certain frequency, exhaust gas flow speed, size of the exhaust pipe and length of the exhaust pipe etc etc etc. . . . .
