The WWII numbers for many engines are not as defined as books indicate. You can pull a lot more out of the engines -- until they blow up.

Preventing the "mixture" to freeze at high altitude, pure water will, the "mixture" won't (within limits).

Too answer the question, yes I'm putting together the gold race video now and will add the cockpit footage to it as well.

Jason, for the past couple of days, after work I've spent an hour or so watching videos from your YouTube channel. This means I kinda know what to expect from the in-cockpit stuff, and I'm very excited! :drink3:

Thanks!! I'm just about finished with the video and will have it uploaded in the next couple of days.
Jason

Furthermore, using U.S.-produced 115/145 grade fuel, the VII Fighter Command P-51s on Iwo Jima also ran 80" MP WEP. The V-1650-9 Merlin, as installed on the P-51H, could run 90" MP WEP, on water-injection.


Interesting, I didn't know that the P-51H was equipped for water injection. Was methanol/water an alternative or "antifreeze" was never needed?

The water injection was sprayed into the induction system to prevent detonation in the engine at high power settings.

Yes, I know how it works. Even the fuel being injected into the supercharger acts as an anti-detonant (is there such a word). Injecting the fuel directly into the cylinders does not have a cooling effect.
