Diesel injector sizing can get confusing fast. Percent over, hole size, liters per minute (LPM)—what do these ratings actually tell you, and how do you know which injectors are right for your build?

Lenny Reed from Dynomite Diesel Products joins us to break down the different ways diesel injectors are rated and why comparing injectors isn't always as straightforward as the numbers make it seem. We talk about what “percent over” actually means, flow ratings, injector sizing, and why choosing the right injector needs to match the horsepower goals and overall setup of your truck.

Whether you're building a Cummins, Duramax, or Power Stroke, understanding injector sizing can help you make better decisions before spending money on your fuel system.

We discuss corrosion and contaminants that can build up over time, how coolant condition can affect heat transfer, best practices when changing coolant, and why maintaining the cooling system is so important on modern Cummins, Duramax, and Power Stroke engines.
