"The Banks unit is a cast-aluminum heat-treated piece, and you can put 300 pounds of boost into it. So, now we have really good air distribution to all the cylinders and equal air distribution of air to each cylinder. Each cylinder runs the same EGT or very close to it, unlike a stock cylinder head where you're limited by the EGT in the hottest hole. Here, the holes are pretty equal."
So what this means is that by using standard Banks products such as the Big Hoss bundle and modifying the cylinder head to increase airflow, Banks was able to get 535 continuous horsepower through a motor that will never, under any circumstances, show EGTs above 1,300 degrees. And all this was done with no smoke because the airflow was perfectly balanced with the fuel delivery. That is how to make race-winning power from a diesel engine.
