The charge booster preferred for load vehicles for ensuring best engine performance at all speeds and road conditions especially at higher load. The arbitrary adaption of turbocharger sometimes gives negative effects like surge and chokes in charge flow to engine. Many approaches reported to match the turbocharger for the desired vehicle engine. Bull all such tasks are tedious and some may be more expensive. But perfect match gives many distinguished advantages and cost worthy. This study focuses on the match of appropriate turbocharger for TATA 497 TCIC -BS III engine and evaluate the alternative possibilities for match other turbochargers. Five turbochargers with different trims were considered they are: trim 67 (B60J67), trim 68 (B60J68), trim 70 (A58N70) trim 72 (A58N72) and 75(A58N75). The Five different road conditions like rough, highway, city drive, slope up and slope down were included for evaluation. The simulation and experimental methods used to find the turbo-match performances. The compressor map used for analysis of appropriateness of turbo-matching.
