Another thing to remember-
The Germans needed water methonol because by the time the G14 arrived (in extremely limited number six) they were reduced to 85 octane fuel due to allied air strikes.
Not sure if that should impact WB numbers but sometimes we find our source data assumes perfect conditions. Sometimes the test data is from factory tests and sometimes even comes from original performance requirements:
I saw one TAIC report on the Ki84 with data based on estimates based on combat reports from Yank pilots.

I have never been a fan of reducing performance based on 'supply' of fuel.

Yes, its an Axis bias opinion, but the opposite can be said, too.

One thing that made the S3s so much fun is that sometimes the Bad Guys won. And we loved it.

I believe the numbers should be based on performance with best fuel divisors, same as we have perfect weather divisor. If you want to simulate lower octane, then develop a logistics game. The bomber dudes will then have other options than to just close a field, ad nauseam.

The only reason the Germans didn't have higher octane fuel is because the Allies bombed the chit out of production. That outcome should NOT, repeat, NOT be inserted permanently into a flight model. That skews the outcome for our sim, when it should be in-game results limiting fuel.

Ok, then... we need 150 octane performance for the spits and mustangs.

Same argument. ignore the teething problems and the shortened lifespan of engines.

Sauce for the goose? How about some for the Gander.


Actually, I think the 87 octane gas is the REASON they added methanol injection- and that allowed it performance that I think is pretty much spot on modelled by the FM gang.
It's the performance that matters. And it's really close in the game I think. (tho' the G14 might be a tad fast at sea level.) I'm a battle of Britain aficianado, so my favorite rides are always the Spitfire and 109. Lots of fun in WB these days.

I've always approached it as " if I parachuted into 19**, what would be typical condition of a service a/c in squadron use"

The P51-D is modelled with 150 grade fuel (ETO variant)

It just makes the engine and plane more usable on the Spit 14.
The climb rate at BST1 is not all that impressive so BST2 offers something in between which is actually "default" full power (on std fuel).
Push through the gate for BST3 emergency war power +21lbs if needed.

Hmm, why not try it out for the next update and see if it's a good addition or not.

I'll build the engine this week. The question is what would be the logical temperature rise? The Pilot Handbook states both +18 and +21 lbs as 5 min limit, with +9 lbs for 60 min. However if it takes 5 min to overheat the engine at +21 lbs, then using logic it should be a slower degree/seconds rise at +18 lbs. I'd estimate around 10 min for overheat at +18 lbs, sounds fair? +18 lbs is ~91% the BHP of +21 lbs. The P-51D's 61" Hg boost is also ~91% the BHP of 72" Hg. These boosts have a 15 min and 5 min limit, so a 10 min limit would hopefully be on the safe side for +18 lbs.


Regarding the 109G-14 it enters the arena at the same time as the 109K-4. The G-14 is pretty much a poor man's K-4, having the same handling as the K-4 but inferior speed and can't use the 30 mm cannon. I can't say the G-14 is to good to have in the game since the K-4 is better. Against the Spitfire IXe the 109G-14 is faster, but the Spit XIe turns better, have superior firepower, and doesn't suffer from the elevator becoming heavy at high speeds. I'd say the Spitfire IXe is quite on par with the G-14 and K-4, depending on the pilot's fighting style. I'd definitely rate the Spitfire XIV as overall superior to all Bf 109's if flown to it's strengths and altitude. Don't fight the Bf 109's at the deck in the Spitfire XIV, fight them at 10k or higher. The Bf 109G-14 and K-4 have great engine power right at the deck but suffers at mid and very high altitudes compared to the Allied two stage superchargers.

die sonder notleistung darf höchstens 10 minuten entnommen werden. Bis zur nachsten entnahme ist eine pause mit geringerer motoleistung von mindesterns 5 minuten einzuschalten.

"the emergency use may not be more than 10 minutes. Until the next use, a break with a lesser power of at least 5 minutes is required."

This is what I come up with from the handbook of MW usage in the G-14. - https://drive.google.com/open?id=0B-ehX ... 3ZCdldDNWs

I can't find data to support a speed above 352mph at SL for the 109G14.
Doesn't mean it isn't there, just that I can't find it.
finn

You can program the PPM to have a forced wait time in between uses. (instead of just temp limited)

perhaps you have a point finn. This translates to 348 mph Level speeds in 109G with DB605 AS (MW50)
