You should be more specific. Here's a good site to learn on.

I've operated engines with turbos as bis as a VW beetle to ones that weight 10 pounds. They all have there differences depending on fuel and what the goal is.

It all depends on the T/C model, whether axial of centrifugal model, the choice of the compressor build, the turbine build, the engine and the rating it is required to run at. What power are you requiring, 50 bhp or 50,000bhp? Only the turbocharger manufacturer can help you to match the T/C to the engine application, ie constant speed for a base generator with variable load or traction with variable speeds and loads; be that either on a marine power curve, locomotive power notches or road load. I suggest that you contact several turbocharger manufacturers for their help.

The link attached is unfortunatly written in German, but if you need I can halp you to translate into English.

You may be able to glean some of this information by looking at the turbo's compressor map. A good description of how to read a compressor map can be found here, as well as links to various common turbo manufacturers:

Theres alot of other factors to consider. Ambient air temperature, atmospheric pressure, flow characteristics of the cylinder heads, intake manifold, throttle body/carb, and exhaust system, engine displacement, engine RPM, and timing.
