' Tests of the Fw 190 A1/U1 with the improved BMW 801 D-2 engine displayed very good flying qualities, and series production of the Fw 190A-3 followed in the spring of 1942 at all factories. The Fiesler factory in Kassel was also included in this project. A power increase to 1700HP with the BMW 801 D-2 had been achieved by raising the compression ratio in the cylinders and increasing the low and high revs of the two-speed compressor. The higher supercharging ratio and pressure forced the use of 96 octane C3 fuel instead of the 87 Octane B4.'

This is interesting as it shows that the higher ATA BMW 801 was introduced from Spring 42 onwards and that the Focke wulf the RAF captured and tested against the Spit VB was the higher boost variant not the lower Boost Fw 190 A4 we have in game.

So once again please can we have an early Fw with boost levels accurate as far as the Channel front is concerned?

Blue is already dominating, haven't you read that thread? http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

This sim doesn't claim to cover the Channel Front.

Aha, did U ever have a look in the skin folder?? There's tons of Spits, Hurries, Ponies and T-Bolts which met the A-4. Not to forget the AEP-Pack, dealing with the western front. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

at least in VOW2 the Fw190A4 owned the Spitfire Mk.Vb - it was a massacre.

He is just pre-postin g2 years in advance.. to cover any BoB gaps.

than ok, having A-1 , A-2 and A-3 in future BoB adons with different performing BMW801 would be nice, indeed http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Fw A4 owns spit Vb - thats not even debatable. It did however own it even more than it does in game. Fw was the first Uber plane of the war ( 30 mph faster than nearest equivalent )

Our A4 is not even as good as an A3

Western Front yes - Channel Front no. We have the Normandy & a "Med" map but not a true Channel map.

Manual PP - 90% constant and it'll fly just
fine.

The BMW801D was always bench tested at 1.42ata@2700rpm 3 minute maximum power. In the field, some of the A3s ran rough at that boost level and suffered problems with the exhaust system. This led to many Fw190s being derated, or limited to 30 minute power at 1.35ata@2400rpm.

The A4s, which didn't enter production until June 1942, would have benifited from improved fuel mixture and plated exhaust systems that would have allowed full power. In the difficult operating conditions on the Ostfront it is very possible that many Jabo would have been limited to the 30 minute rating to improve engine life.

One thing that is relavent to PF, is that the current 2400 rpm maximum that the A4 runs at is a 30 minute rating. With radiator open, the Fw190A4 should be able to run at 110% throttle with auto PP for 30 munites without overheating.

So, your theory is that an Fw190A3 or A4 running at 1.42ata@2700rpm only operated on the Channel Front?

If Oleg is addamant that Fw A4 had 1.32 ATA on Eastern front then I definitely propose on Western front it commonly utilised 1.42 ATA give the same timescales.

Simple fact is - right or wrong - Luftwaffe respected the RAF way more than it did VVS

Same thing goes for the D-9 '44 and '45. After the SonderAktion-1900 1600 PS @ 3000 RPM was cleared for continuous use and 1780 PS @ 3250 RPM was cleared for 30 minutes use. Right now the only way to reach 3000 RPM on auto-pitch is at 110% throttle and you over heat way before 30 minutes. And the only way to reach 3250 RPM is with WEP (erhohte notleistung on the '44 Dora and MW-50 on the '45 Dora).

All that being said at 110% throttle and with WEP the '44 and '45 speeds at SL and FTH are close. I don't trust the gauges when it comes to ata and RPM. I think in FB they don't represent what the FM can do at a given throttle %.
