One of the most impressive, talked about, and buzz worthy things at the 2017 PRI show was the awesome engine you see before you. This is the all-billet Duramax style engine that deployed both twin turbochargers and a PSI screw blower. We gawked at the thing like everyone else because it was so big, so awesome, and so imposing you really had no choice. The mill has a presence about it because of the flash of all the billet parts and the inclusion of the craziest compound induction system we have ever seen.
This video shows us the engine hooked to the dyno and running. We do not get any power numbers out of it here. These very early and fairly light pulls are designed to let the builders survey any potential issues that could arise wit an engine and to let them get in there and make the necessary tweaks before the engine i rally puller in anger.
Expectations for this mill are high. Wagner is expecting a few thousand horsepower and prodigious torque output and when they get down to brass tacks and really start pulling on this thing at the pump we’re sure the numbers will be headline news. Unfortunately we do not have the ability to send someone up there to camp outside of the dyno shop owner’s office and pepper them with output questions until they break but we’re going to keep an eye on this thing.
Few things look neater than a V8 with a PSI screw blower on top and a pair of turbos plumbed in as well. Add to that equation the fact that this is a diesel and we’re looking at something really really, special here.
How does that intake system work? Are the carbs and blower BOTH blowing into the same plenum?
The tubular sections that the turbos feed are valves that keep the turbos separate from the intake. When the turbo boost is high enough, they open the valves, allowing them to feed below the blower. Having both types of superchargers feeding one intake introduces all sorts of challenges. I’m excited to see if they can overcome those issues in time for the Ultimate Callout Challenge!
