BTW, for racing, the engine with the most power is not usually the winner.
The one with the best chassis setup and driving skill usually is.
That's where I'd spend the R&D time.
I realize that, but I am not a racer. Isn't geting the most out of your engie part of having a good setup? I just like to know what my engines are cabale of. But if you are a racer wouldn't you like to be able to match the load your buggy or truggy put on an engine then be able to try different setup to see how your engines respond? with a setup like this I will be able to test different pipes and fuels ect. to see what give the engine its best performance. I'm not a racer but if I was this would be a great tool to help me with my setup.

You will still not gain anything buy running props on the engines then compairing them to each other. Some have different porting, carb sizes and so on. one with high timing but low transfers may turn a prop the best but suck on the top end and vise versa.
The work has already been done for you. just look at see what the local car guys are running in their fast cars and then get that engine.
Also if you are going to run a prop then you will need add more oil to regular car fuel which is in the 10-14% range for revabilty. props are more of a steady stae running which regular car oil will not be enough.
but again your stuff have fun and good luck.
Right now I know how many rpm's my engines turn in a my MBX5T with stock gearing(Werks B6 does 38250 RPM) for example.once I get it all set up I will be able to get a prop to match those RPM numbers and then i can use that same setuo on different engnes and see how they compare. then I can use a larger prop to put evn more load to estimate which of the engines has more torque.
As far as fuel that is part of the reason for doing this. I mix my own and I can play with different mixtures to see which one perform the best.
