1986 Buick Grand National


1986 saw significant changes to the Grand National that would make it truly one of the best American performance cars of the mid-1980s.  Buick added an air-to-air intercooler, adjusted the turbo, modified the upper and lower intake manifolds, and redesigned the exhaust system.  All of these changes added up to a boost in power to 235 bhp and 330 lb-ft.  Other changes included a revised front air dam with an opening in the center to allow cool air to reach the Intercooler duct and a revised grille with fine vertical bars.  Production: Grand National: 5,512.






Well you have to race it at least once.  Bone stock (well improved exhaust and a cold air kit) ran a best of 13.45.
