Oil and radiator control = optimal engine performance?

490? How?

I suspect a strong feel of disbelief in your words Tom

But anyhow I convinced myself to (re)write the answer :

Increase your speed by diving slightly at 5m/s. Once your reach 500+ (usually somewhere btw 520/540) level your nose and keep your trajectory straight with the utmost of attention. Your oil&glycol rads shld be nearly fully closed (at high speed the amount of airflow would be enough to cool your eng).

And Taaada ... Th's it Your speed will stabilize at 500 and then will very slightly decrease to 480/490.

Note that with a very shallow descent (what was authorized by international authorities for high speed record) you can keep 500 IAS deck (with something like 50m/min descent (150ft/min)

I'll give it a try, Tomcat, but I'm not sure if I believe that is sustainable in truly straight n level flying.

Btw, my results came from me cruising at exactly 100m above the English Channel: damn near sea-level.

No it's not. If it was it wld not hve been called max speed but max cruising speed Heat will soon force you to open the radiotor.

Now I see what you're talking about. Yes, that's totally possible. I think Tom got mixed up because I brought up level flight first.

Ok, i understand now. Yes, the current FM keep the energy, but i thought you can reach the 500 with pure engine power
