To
capitalize on its recent manufacturer's cup win in Nascar's Grand
National Series, Buick decided to build a special car in 1982. A handful
of those early Grand Nationals packed a 175-hp turbocharged 3.8-liter
V-6. The original Buick Grand National wasn't quite the fire-breather of
the later cars, but realize that this V-6 made more power than the
5.0-liter "high-output" V-8 in the 1982 Ford Mustang.
Soon, fuel injection, an intercooler for the turbo, and more boost increased the Grand National's performance. In fact, power went up just about every year until the last year, 1987, when the car hit 245 hp in standard trim and 276 hp in the limited edition GNX trim. The GNX was one of the quickest cars on the planet at that time, and these mean black Buick Grand Nationals have long enjoyed cult status among casual enthusiasts and drag racers. The robust 3.8-liter V-6s can withstand very high levels of turbo boost. So these cars are tremendous platforms for racing. And the quickest street-legal modified cars can routinely run in the 9-second bracket in the quarter-mile. That's a full 2 seconds quicker than the quickest modern exotics.
