[net.auto] Turbo Advantages

dcn@ihuxl.UUCP (Dave Newkirk) (02/22/84)

I own a turbocharged car and like it very much.  A turbo is simply a way to
get more horsepower from an engine.  It uses the exhaust gas pressure to
drive a small turbine, compressing the intake air before it reaches the cylinder.
More air + more gas => bigger bang!  This is an alternative to trying to
stuff a larger engine into a car.  Its advantages are:

	+ same gas mileage as non-turbo engine when turbo is idle

	+ same power as a larger engine

	+ little additional weight or space used for turbo

The disadvantages already mentioned in a previous article are mostly
engineering problems that have been solved.  The only significant one is
the turbo lag, which varies from car to car.  The newest designs use small
turbos which can 'spin-up' very fast, and better engine technology to improve
the non-turbo performance (initial acceleration from a standing start).
Just ask Ford, GM, Chrysler, VW, Audi, Volvo, Saab, Lotus, Maserati, Nissan
or Mitsubishi about turbos.
