THE EPIC STORY OF THE BUICK TURBO V6

摘要

Buick started playing with turbochargers in 1976 when it paced the Indianapolis 500 with a Century equipped with a special turbocharged 3.8L V6. The actual pace car needed the boost cranked up to 22 psi to keep pace with the field. It produced 300 hp while the commemorative edition only had a V8 with 165 hp. A turbocharged 3.8L didn't go into production until 1978 when Buick developed a 165 hp that had an electronic spark control or a "turbo control center." The system used engine knock sensors to detect preignition in order to retard ignition timing of the HEI distributor. Unfortunately, the turbo had to suck through a two- or four-barrel carburetor and blow through a restrictive catalytic converter.
