By 1989, Banks turbo systems were running on over 30,000 Ford and General Motors non-turbocharged trucks, literally breathing new life into these trucks. The Dodge Ram equipped with the Cummins 5.9-liter B-Series was the new kid on the block and the first factory-turbo diesel when introduced that same year. Even though it had a factory leg up over the Ford and GM to Banks… there is ALWAYS room for improvement, and with that in mind, they came up with a system of components designed to give the engine an extra dose of performance.
These performance parts were sold in stages and included such upgrades as a free-flowing filter with a performance exhaust, a new turbine housing and wastegate that improved response and usable power range, and an intercooler with intake elbow. Altogether the combined parts added 80 horsepower to the stock 159 hp level. Even though that is hardly the power that customers are used to today, the improvements were gargantuan. Power came on sooner, was more usable, fuel mileage increased, and towing became enjoyable instead of danger.
