BoB Spitfire 100 Octane fuel

Good that you started a new thread (instead of the mellee I see in the Friday Update thread)

It gives me the opportunity to ask the question I always wanted to, but never dared:

How many octanes does the fuel the SpitII flies with, has?


~S~

According to the boost guage, 87 Octane, it does not appear to have had the modification that allows 100 octane and its +12lbs boost.

It (Spit II) does have 100/+12 performance specs though, regardless what the boost gauges show. Effectively its the same thing as Spit I with 100 octane, there was no meaningful difference between the two in performance at high boost.

I concur! So the Ia with 100 octane should have the same performance as the Spit II in the game.

But the game's Ia with CSP currently doesn't even match up to the real Ia's performance with 87 octane (source, Alfred Price - The Spitfire Story). So there's something amiss with the Ia FM that isn't simply down to fuel octane.

Also, in your opinion, is the Rotol Hurri in the game performing at 100 octane levels, as is the Spit IIa?

I'm not arguing here, by the way. I'd like to know!

Where do I find that spec data for the SpitII in CoD?
I do understand that at +12lb/100 octane the Merlin III and Merlin XII have the same boost available and probably the same output.

OK guys,

IF you tell me that the SpitII today runs with 87 octane fuel
and it flies like an overmodelled F-16,

what do you expect its performance will be if 1C hears your comments and grants you 100 octane fuel?

I can't really comment on the SpitII except to say that when I did some test runs it didn't achieve the max speeds I found on the web. It was quite close but slightly under but it was close enough for me to be happy. Its probably the most accurately modelled a/c in there.

I wouldn't say it performs like an F16 but if you are comparing it with the 109s you don't, as I understand it, have an accurate 109 to compare it with (yet).

Klem my friend, we agree to disagree

The SpitII is the second most accurately modelled TIE fighter!
(The first one being the infamous LA5-FN Oleg gave us after a patch - which could perform continous loopings until it ran out of fuel).

Easy check: With a SpitII (Immelmann manouver): Full speed level, switch to vertical (3-5g), climb 200-400 meters, switch to level (3-5g) and roll back (head up). Check your speed.

Repeat this with a SpitI

The good news for the devs ought to be that having a number of tests with different weights and engine outputs, but the same airframe ought to make the fms more accurate.

When in steady state flight like a speed test, the drag cancels the thrust and the lift cancels the weight. Obvious I know, but it makes it hard for the devs to know which bits are right, or whether errors are canceling.

If they match all the tests, they know they have a good model.

Sadly, I don't reckon this will happen in the next patch. Ilya mentioned something about FUTURE fm development as if the staff had left or were working on other things.

@Grathos - as Talisman says, we want accurate fms, not improvements for one side, and- yes- the 109s are too slow.

Oh besides, Blacksix already posted an answer I think:

This "octane fuel" saga is becoming marvelous and I am struggling to grasp the meaning of trying to convince yourselves (first) and others (later), that a change of fuel will solve the bugs in the flight model which are the reason why your Spits get mercilessly kicked...


Just to be clear:
I am convinced that you are getting kicked in the SpitIs (and you rule in SpitIIs) because of the bad flight model bugs.
However I am not convinced that the reason lies in 13 octanes (the difference between 100 and 87 octane fuel).
