Well, my idea involved using the ps pump to drive the turbine, because I was planning on disconnecting the ps anyways when I start racing my car. My idea would use the oem ps pump, and then just use extended ps lines to wherever the the turbo would be mounted, and then just add fuel management to the car, like any other fi setup. I just figure, why not use existing FACTORY equipment. I can't imagine the ps pump not being up to the task. It pushes enough fluid to power the steering rack. I have the math background and would do the design myself. If I DO decide to try and engineer it myself, I'll probably modify the turbine housing of a popular model of air turbocharger, like a t4 or something, to accept hydraulic lines, so that it would be cost effective to mass produce if it worked
. The only thing that would have to be researched would be the area ratio of the turbine, the trim of the wheel, and the wastegate pressure, since I will obviously be using an internal wastgate setup (don't want hydraulic fluid going all over the place
). The math is nothing a little thermo and fluid dynamics homework can't handle. I'll also probably be taking a turbomachinery class in the winter on top of my air-breathing propulsion class, so I might even be able to engineer a turbine wheel myself. I know it has probably been done before, I'm just looking for a project, maybe even a senior project coming up later this year, since I'll be graduating in june. (hell yeah.)
