I recorded a few car engine sounds and processed them to have a engine loop for Trigger.

Running the sample through a spectrum analysis, the highest peak is at 999Hz, i.e. 999 combustions per second.
Looking up the car on Wikipedia reveals that the car uses a 4 cylinder engine. Being a 4 stroke engine, a cylinder combusts every 2 revolutions. In other words, there are 4 / 2 = 2 combustions every revolution.
So the calculated speed is (999 / 2) = 249 rev/s = 7470rpm
Science, it's amazing.
This is very nice
Hello, i modified the sound to use it in a mini-game i am doing to fit a tank engine, i gave you credits, check it out if there is something wrong about the credits or if u liked.
