The accompanying graphs show the results of dyno tests on a 366-cubic-inch Banks prototype Twin-Turbo engine. The tests were conducted with and without intercooling on 91- and 100-octane gasoline. As the tests show, you can run higher boost when proper intercooling is installed, thus achieving higher horsepower and torque. To reach power levels above 1000 hp, turbocharger boost increased to just over 20 psi, and larger fuel injectors had to be installed along with an equivalent fuel pump. The fuel injection and engine management system was recalibrated for the octane of the gasoline being used. These graphs indicated just how flexible the Banks Twin-Turbo packages can be to meet your performance needs.
