  • Q7
    What is the purpose of a performance camshaft in an automotive engine?
    To increase power output and improve engine performance at high speeds
    To enhance interior comfort and reduce noise levels
    To generate more engine coolant for temperature regulation
    To decrease fuel consumption and improve fuel efficiency
    30s
  • Q8
    What is a camshaft made of in most automotive engines?
    Steel or cast iron
    Copper or bronze
    Plastic or rubber
    Aluminum or carbon fiber

  • Q9
    How does a performance camshaft differ from a stock camshaft in an automotive engine?
    A performance camshaft has more aggressive profiles for increased lift and duration
    A performance camshaft has fewer lobes for simpler valve control
    A performance camshaft is made of plastic for weight reduction
    A performance camshaft is designed for slower engine operation
