FAQ for the last Day

  • Is turbo or blower better?
  • A supercharger is also known as a blower. It is generally less efficient than a turbo and you can usually get less power out of an engine with it than you would if it had a turbo.Blowers typically have much heavier moving parts (especially roots type) and more bearings, and added friction from belts. The turbo is (IMHO) a far more sophisticated means of forced induction. The only real benefits I s...

  • How does a blower work?
  • Blowers increase the pressure of the absorbed gas by a series of vortex motions formed by the centrifugal movement of the impeller. When the impeller is rotating, the channels in the impeller push the air forward by the centrifugal movement and a helical movement occurs.How does a air blower work? Air blowers work like reverse windmills. They have a bunch of blades attached to a rotor, which is ca...

  • Will a supercharger hurt my engine?
  • Assuming a properly tuned system, proper oil change and engine maintenance, and similar driving, supercharging generally will not shorten the life of an engine, just as is the case with OEM turbocharging (with proper cooldown for turbochargers. A cooldown period after driving is not necessary with supercharging).What is the main disadvantage of a supercharger? Less efficient: the biggest disadvant...
