Turbo gain level

처리 내용

Do you have any idea about potential power level of 132 kW (180 HP), 700 Nm MAN truck (TGL) 4.5 litre engine with damaged (not working) turbo? As a rule of thumb, for every atmosphere's worth of boost, you'll double the amount of power the amount the engine puts out naturally aspirated. For instance, if an engine puts out 100hp naturally aspirated, the same engine should be able to put out 200hp if you boosted it to ~14psi (air pressure at sea level is somewhere around 14.7 psi ). NOTE: This is considered a rule of thumb and does not equate exactly to the real world. You also have to figure in parasitical drains and other factors when computing these numbers. With this in mind, if you lost the turbo on such a truck engine, you can assume the engine is losing major amounts of power/torque due to the loss of turbo pressure. Production diesel engines usually run in the neighborhood of 15 to 30 psi of boost, though I cannot find an advertised amount for this engine. Even at 15 psi, you can
