A richer mixture also cools the intake more. Heat energy is absorbed to vaporize the gas.

ideally an engine should add the heat before expansion, not during
expanding the heated gas is how an engine works (turning into work some of the gas's internal energy that was produced by heat)
there should be no problem adding the heat before (much) expansion with this engine rpm (unlike eg 2013)

I have heard that MrE is fed up with New Jersey and plans for a US Grand Prix East at nearby Pocono in Pennsylvania,
with a one-off 48 g/sec fuel flow, good enough for 1000+ Hp without the gizmos, as there's full boost and very little
braking all around there, all in order to smash Marco Andretti's lap-record of 221 mph to kingdom come!

One-off refueling for the race as well of course!

I stand prepared to be corrected, but i think you still misread what i was trying to write.
I'm sorry, that was some overly-layered language on my part. What i was trying to say is that since a powerstroke lasts a very short while and the exhaust gas is expelled in a very short space of time, especially at over 10k RPM, it seems to me like there is the chance that not all of the charge in the combustion chamber is combusted by the time it is expelled, especially in the case where there is a saturation of fuel in the air.

It will be better off for Bernie to book memorial day weekend at IMS and set a 250 mph avg

Pocono Raceway would be great - my sister works all the races there, and could surely get me in! I just don't believe that they have the money to update the track to Bernie's standard (aka Tilke).

IIRC somewhere in the big 2014 engine thread there is a link to a paper on Ferrari N/A F1 tests including 18000 rpm
IIRC this clearly states that rich mixture benefits power significantly by improving consistency of combustion
which otherwise affects some cylinders (more than others) at these very high rpm

One of the Mercedes v6 on the dyno suffered a fire. The local fire brigade tweeted about it.

Did the 700 horses survive the fire?

Lol I don't think so. Those horses are crisped.

I was under the impression they were producing a lot more than 700hp?

Nice of them to be specific about which bit of the engine failed!

Would a test room like that would have built in fire suppression? I guess a system like that would automatically call the fire brigade?

Would you believe 701hp?

Yes, it -should- have a built in system. I'm sure that is fit in regulations somewhere that the British government forces on the masses. There are stringent regulations for buildings here in the US. And even if there aren't, I'd expect insurance companies to force installation of a system in order to supply insurance.
