Make you own engines with this simple engine sim. I wouldn't recommend turbo mode as it makes the engines extremely load and annoying. You can make infinite Cylinders (Up to scratch's clone limit) but the sound may break around 360 because of the way its programmed. More engine types will be added soon! Press The key button to turn on the engine, drag the slider to control the pitch, and press "New Engine" to make a different engine.
