Here's what the plan is I need a dyno for a new engine development program. small displacement engines, 50cc some day up to 200cc+. I need comparative data engine to engine, tuning, proto components, etc..
this is all diy budget stuff please keep this in mind. I come from automotive and race engine background so i might know enough electrical stuff to be dangerous, so that's what i need to most help with. I've been searching for more info for awhile and not getting what info i really need.
I do NOT want to run a inertia, nor a water brake. I really need steady state data. I really like the idea of a motoring dyno, edddy current, AC dyno, which ever you may call it. I've been through some other posts:

Now I've read very little about using a AC motor and varying voltage into it to change the load, and I could drive or "motor" the engine and measure the engine mechanical resistance/friction (test piston ring design, or spin-tron) that's about all i could find about that, please let me know if i understood that correctly, and how to go about it.
I need help pointing me toward some info, and i really would like your ideas too. I have a cnc machine shop at hand, and trying to teach myself electronics so if you have some good resources please let me know!
There is a lot more on the details of the project but didn't want to get anymore long winded than it already is.
