turbocharger compared to supercharger
Turbochargers are more difficult to control due to the high temperatures they generate and the way they produce a dramatic rise in air pressure, resulting in large horsepower increases. Although this may sound ideal it usually results in uncontrollable wheel spin and loss of handling to the point of making driving dangerous, forcing the driver to back off and losing the benefits of all this power. All these problems of a turbocharger can be tamed to a certain extent but it involves much extra technology and cost. Apart from this drivability problem the other downside is that this sudden rise in pressure, means very careful engine management adjustments to set the fueling and ignition correctly to avoid engine blow ups. Several Saxo turbo's that we have heard of produced reasonable power but destroyed themselves and the installer then rebuilt them with lower boost to preserve the engine. This did cure the reliability but then power was way down.. Another downside of turbo's due to the very rapid increase in power, is the effect on the transmission components, all turbo's wear out clutches and gearboxes more quickly. These components like gradual torque increases not sudden violent increases.

You didn't say much about superchargers. What exactly is the difference between the two?
