Even in North Africa the DB-601 on later F-models had to be downgraded to 87 octane as 96 was so scarce. There was a reason why the Germans were ahead of the curve when it came to MW and Nitrous Oxide boost, and you are trying to tell me they had no octane issues? These tricks gave back the power but at a cost. You actually believe the Germans had a "distinct advantage here" ? We'll just have to disagree.

[bellator11]

I said they had a distinct advantage in terms of how long their engines could handle emergency boost, that's it. You claimed that the fuel they had was garbage, which is completely untrue, it was the same 87 octane fuel as always. Just because you bomb som refineries doesn't mean that what the rest are producing magically becomes garbage, can you hear yourself ?? And regarding C3, I have no clue what you're trying to get across, I said it was rare throughout the war, you then repeat me?!

[rampking1]

@bellator11

Quite obviously they went to 87 octane as a neccessity, not because they wanted to.

The GM1 and MW boost was a bandaid to try to compensate for it.

Btw, show me exactly any fact in my previous comment not correct.

Are you wanting books, authors, page numbers?

Btw, the DB-605ASCM could reach 2000hp emergency with C3, no boost at all, no 25g tank , no changing plugs. No repeating, right from the book.

"Garbage" is a relative term, it will run but you won't get all the power.

[bellator11]

@rampking1 The Germans were using 87 octane B4 fuel since before the war started, simply because it was cheaper & faster to produce than the 96 octane C3. As for the ASCM version, it needed MW50 to reach 2,000 hp, same as the DC version. Running on C3 without MW50 engaged and 1800 hp could be achieved.

And again, the fuel they had was not garbage, it was either 87 octane B4 or 96 octane C3, and there was no difference between that produced in 1939 or that produced in 1945.

[rampking1]

@bellator11 Your exact words: " The Bf-109 used 87 octane synthetic fuel like every other German a/c of the war"

How many contrary examples do want or are you going to delete this?

[bellator11]

@rampking1 What? Contrary how and to what? The Bf-109 DID use 87 octane B4 fuel, just like every other German piston engined aircraft of the war! 96 octane C3 was used to increase power when available. Is this really so hard to understand ?? Only the jet aircraft used a different type of fuel, the coal derived J2..

[bellator11]

@rampking1 Lets see what you've claimed so far:

1) Germans used natural fuel = FALSE

2) The DB605 ASCM achieved 2000 hp without use of MW50 = FALSE

3) The Germans had no high octane fuel after 43 = FALSE

4) The fuel they had left was garbage = FALSE

Are we really going to continue this pointless discussion ??

[bellator11]

@Dreadnought5001 Actually British fighters outnumbered German fighters greatly over Britain. It was only in bombers that the Germans had a higher number of a/c in the sky. And despite the disparity in numbers and the fact that the Me109 couldn't hang around for long before having to head for home, it did manage to acquire itself a roughly 2:1 kill/loss ratio over the RAF fighters.

[bellator11]

@hiperformancestore Why do you keep repeating the same false information again and again? The Bf-109 used 87 octane synthetic fuel like every other German a/c of the war, whilst Allied a/c used 100 octane natural fuel. And finally neither a/c are run at max manifold pressure these days anyways. In short: it has zero effect on these comparisons, its all about the aerodynamics.

[rampking1]

@bellator11 Yes, you are correct, lets end it.

I am willing to listen but when you misquote me you are going to another dimension.

Show me where in any previous comment that: "Germans used natural fuel"

I only said : "natural and synthetic refineries were being bombed" in regards to the war situation and shortages. A bit of a leap on your part ? Can't defend myself for something never said.

Btw, I suggest you add a caption pointing out that Skip is the second man interviewed.

[rampking1]

@bellator11 Yes, cheaper and faster, the best thing about it.

It's not garbage when it is about the only thing available.

So Daimler-Benz was just happy designing engines with an 87 octane minimum requirement, good..thanks. That B4 must be good stuff.

Btw, the Bf-109 F1-2 and the Bf-109 E w/DB-601N engine all used C3, higher compression, more power.

Also the DB605 achieved the 2000Hp with C3, at special emer. power , no mention of MW or GM1 boost.

That is right out of the book.

[bellator11]

@rampking1 The Germans didn't use natural fuel, it was all synthetic. Furthermore the fuel that was left wasn't garbage, it was still the same 87 octane fuel. C3 was rare, sure, but that was the case throughout the war thanks to the longer production time. C3 was 96 octane and it was used even in 1945, but again in very limited quantity.
