If you’re a diesel performance enthusiast, you’re probably already familiar with what a single turbo is, what compounds are, and even how variable-geometry turbos work.

But the times, they are a changing. The ’11-to-current 6.7L Ford has a unique turbo that employs two compressor wheels and one exhaust wheel, which doesn’t really fit into any of the above categories cleanly. It still has a variable exhaust side for quick boosting, and when it comes under boost it arguably hits harder than any of the other trucks on the market today. The idea was to package the flexible and quick-spooling nature of parallel twin turbochargers (one turbo for each engine bank) into an easy-to-package and cost-effective combination.
