I had the opportunity to drive an 06' Common Rail with an S300/S400 compound turbo set-up on it this past weekend. Truck dynos right at 600hp in it's current stage. The chargers worked awesome on there, instant spool-up and no need for a pyrometer.
Knowing next to nothing about compound set-ups is there any reason those wouldn't work on a 7.3L? I would think that with a larger displacement engine they would work even better on the Powerstroke. But like I said, I don't know much, thats why I'm asking.
The S300 has mutliple set-up options (i.e inducer, comp wheel, turbine options) and the same goes for the S400. Either can be upgraded pretty easily to flow just about any amount of air. Plus the chargers are cheap in comparison to others on the market. I'm just curious is all.
