Gale Banks is joined by PPEI Custom Tuning’s Kory Willis. The two discuss how they’re going to push the engine harder than ever before and spool.

Losing a Gasket

Gale and Kory discuss how the ways in which they don’t want to kill the Duramax. They don’t want to do it via an avoidable oversight. They do want to kill it after getting every bit of data out of it and make it an informed failure.

Measuring Intercooler Efficiency

There isn’t one intercooler manufacturer that measures and publishes the intercooler’s efficiency. Gale Banks currently has two patents for the tools he has developed to measure it. Spoiler: it’s the iDash.

iDash CSV file structure

The iDash is cost-efficient and gives all the data you need in a CSV file. The customers are going to be more intelligent than the people developing the products.

Getting air density to the cylinders

Gale explains the importance of air to fuel ratio and how it affects getting air density to the cylinders.

Intelligently increasing the swirl

Intelligent porting and spool is discussed.

The crankshaft is your powerbroker

The power stroke is the only stroke that puts horsepower into the crankshaft.

Density path through the engine

The density path is often overlooked.
