I was searching online for some different variations of forced induction used in autosports. I am familiar with the almighty turbocharger and superchargers, but was wondering if any one has seen a turbocharger that feeds the turbine using hydraulic pressure, say, from tapping into powersteering pump lines, rather than using exhaust gases. I am really just looking to see all the ideas that people have come up with over the years. I am also looking at the benefits that may come with a more compact turbo unit that could be mounted somewhere other than right between the two biggest heat sinks in the engine compartment. Anybody with links or info on where or who to look for? Thanks in advance.
