Inaccurate performance data for BOB fighters in COD comparing to RL data

Which is why squadrons are generally equipped with one aircraft type.

Kinda hard to keep formation if some aircraft are using 87 octane and some 100 octane...

No, at any manifold pressure and rpm setting below the knock limited performance of the fuel, the power will be the same.

Basically at any manifold pressure below +9lbs (limit for 87 Octane) in the Merlin, the power is the same for 87 Octane or 100 Octane fuels.

The problem is that people think the higher octane fuels magically give more horsepower when in reality they merely allow the engine to develop higher power at higher manifold pressures without engine knock.

This is totally true. To see every day on the street when the people buy it their car the expensive 100 octane "V-Power" fuel, though into the car 95 octane would be needed

It has been very long, interesting discussion about... FUEL and I would like to ask you guys what you propose in the next patch Flex-Fuel Spitfire or Spitfire Hybrid?

A Spit from Toyota's Burnaston plant ?

With all those big Merc and BMW engines Germany won't hve a chance there .

[Kurfürst]

Think of milage and service costs..

[Crumpp]

Do you guys ever fly?

Sometimes....

My GF took these pictures a few weeks ago.

Most cars these days, especially high performance vehicles, have engine knock sensors, which sense detonation and then automatically retard the timing to prevent pinging. Depending on the car and how its CEM is setup, higher octane fuel might give better performance.

Merlin engines were limited to 6.25lb boost when using 87 octane. At ~10,000 ft the Merlin III would produce 1310 hp at 12lb/3000rpm versus about 1000hp at 6.25lb boost. It might be possible to go past 6.25lb with 87 octane, but this leaves the engine with no safety margin since detonation is dependant on several factors, not just manifold pressure.
