Thank You. > -Chris The sole function of the turbocharger is to get more fuel/air mixture into the cylinders so that the engine can develop more power. When the throttle is closed, very little fuel/air mix gets into the engine. As a result, very little power is generated. As the throttle is opened, more fuel/air enters and more power is produced. In a normaly aspirated (non-turbo) engine, you hit a limit when the throttle is fully open and the engine is breathing in as much fuel/air as it possibly can. At this point, the engine is producing as much power as it can. What a turbocharger does is use the exhaust gasses to spin a turbine that is connected to a compressor. The compressor forces more air past the throttle than would normally flow. With this increased air flow (and the fuel that gets mixed with it), it's almost like the throttle is opened "farther than fully open", if you catch my meaning. The upshot is, the turbo forces more fuel/air into the engine than a normally aspirated engine could breath and, therefore, produces more power than a normally aspirated engine could. I hope this makes it clearer to you. John
