Clocking more than 267 mph, Banks Twin-Turbo Trans Am breaks Banks’ own 1981 record for World’s Fastest Passenger Car
1986 Banks Pontiac Trans Am World Record 260.212 mph. Clocking more than 267 mph (one-way), Banks Twin-Turbo Trans Am breaks Banks’ own 1981 record for World’s Fastest Passenger Car
Powered by a Gale Banks 1,400 horsepowered, twin-turbocharged 456 ci big block engine, and using Banks reverse deflector turbo pistons, camshaft and turbo valves, the Trans Am recorded an average speed of 260.212 mph. Still sporting stock power windows, tilt steering and functioning stereo, the Trans Am recorded a one-way blast of more than 267 mph – approaching an incredible 390 feet per second. The Banks Trans Am was the world’s fastest, stock-bodied passenger car on gasoline, eclipsing the 1968 Kehoe-McKinney-Banks Sundowner Corvette record by nearly 20 mph.
The Studebaker era ended for good at Bonneville with the Banks Firebird’s stunning 267 mph clocking. This is the first brutally fast passenger car record at the salt and the third in a row for Banks’ team.

Cummins Grid Heater Bolt Fix: Banks Monster-Ram
On all 6.7L Cummins, the factory grid-heater bolt is a known risk: if it breaks loose and reaches cylinder #6, engines are replaced—not repaired—an outcome costing north of $30,000.
