We’re getting closer and closer to the installation of our Pusher Intakes high-mount compound turbo system, and a few more pieces of the puzzle are here: a CP3 pump, brand new injectors, and feed tubes fresh in from the folks at Exergy Performance.

Compound turbo systems are no joke, and when it comes to fueling, having the right components for the job plays a major part in longevity and unlocking power potential. Exergy Performance is an amazing choice, and to learn why, we reached out to the company and spoke with Rick Newbury.

“What you have with a compound turbo system is basically a lot more air, and you’re going to need to send more fuel to match it,” said Newbury. “With those 100hp injectors, a modified CP3 pump goes hand in hand. Doing one without the other leads to decreased potential. The feed tubes, meanwhile, are recommended for replacement whenever doing a set of injectors.”

Going with Exergy for our build was a great decision, and the company was recommended for its expertise, attention to detail, and versatility, not to mention its history. “Our background in OE development and manufacturing affords us a unique perspective of the high-performance world,” said Newbury. “We know what various features and specifications need to be to ensure proper function, production processes, and quality control. The verification process and equipment we use is very untypical of a standard diesel repair shop, and allows us to look at many more system performance characteristics beyond average fuel output.”

Exergy Engineering (and its division, Exergy Performance) was started from being eliminated from the Bosch Corporation in 2006, and pivoted toward providing independent R&D service to diesel applications.

These brand new, Exergy 100hp fuel injectors will support up to 750hp.

Speaking of untypical, the 2003 Cummins dually at the center of this build will be totally unlike its former self when all is said and done. Exergy is making that goal possible, starting with the 100hp injectors.

These units are capable of supporting up to 750hp, and since they’re a bit larger than what we need, they offer room to grow in the future, should we decide to go further. They also help maintain great drivability and produce little to low smoke output.

This particular Exergy CP3 pump model can handle up to 800hp, meaning the truck owner has some room to grow if he ever decides to crank things up a notch.

Next, we have the CP3 pump. This unit is actually based on the 6.7-liter Cummins pump, and can handle up to 800hp. For what we need, this is more than enough, and ties back into the injectors with permitting more room to grow in the future.

Finally, we have the 5.9-liter Cummins feed tubes. “We have seen cases in the past where an old feed tube may not seal properly with a new injector, and can cause a leak,” said Newbury. “There are also edge filters in the tubes that collect contaminants over time. If they’re not replaced when doing new injectors, you could have those contaminants pass through and damage the new injectors.”

Feed tubes like these have edge filters that collect contaminants. The old, stock feed tubes will likely be chock full of debris, so with clean ones installed with our new injectors, fuel will be able to flow freely to the injectors.

As you can see, Exergy Performance has made an important contribution to the build – not just in terms of helping the truck generate more power and torque, but also in keeping it stable and under control for whatever lies ahead.
