SUPER-TURBO | Building A Monster Truck 10

Here’s the first look at the Banks supercharged super-turbo 7.0L Duramax race engine designed for use in a monster truck. Gale wasn’t happy with the 666 horsepower we got. When he tested the Monster Mutt, he learned you need 1200 horsepower at least to be competitive.

The first thing we look at is the Banks high-temp, cast, and ported exhaust manifolds. Comparatively, the stock manifold has very small exhaust ports. This is important because of Cylinder Fill Percentage which is the manifold air density that makes it into the cylinder. Once it’s in the cylinder and the combustion process is done, you’ve got to get it all out of the cylinder.

Afterward, we get to the super-turbo system. The turbochargers are 68-70 Precision ball-bearing turbochargers. They have a 2618 forged aluminum compressor wheel and a 713c Inconel turbine wheel. When the engine goes back to the dyno cell, it will get two of our Big Ass Air Filters and dual MAF sensors.
