Re: Building a 10,000 rpm NA engine.
How about having an engine dyno set up to do instrumented runs once you've got a "mule" to ride? This would be worked with the ECU selection task, as the ECU selected will integrate into the engine dyno.
Using a chassis dyno really isn't going to be realistic, given the thought out roadmap that will guide progress.
I agree with YT's comment on needing to look closely at the oil passages (especially in light of Bob's input on repeated failures of the crank at 9.5k rpms!!)
