The Jetfire’s Unique Turbo
Oldsmobile produced this revolutionary fluid-injected turbocharged aluminum V8 providing one horsepower per cubic inch in this sporty, compact high performance car two years before the advent of the Ford Mustang and the Pontiac GTO.
The addition of the fluid injection feature to enhance the performance of the turbocharger introduced a degree of complexity. This resulted in extensive service problems, which caused the life of the Jetfire to end after two years of production. Few Jetfires still have operational turbos. Many have been converted to four-barrel carburetors.
