TA 152: IL2 GB is really realistic?

[9./JG54_Klippel01]

LINK OF THE TEST:

5 min of test. Altitude: 11100m. Throttle: 100 per cent. Fuel: around 550l. Radiator: closed. GM-1 activated. Boost: Activated.

RESULTS: 410 KM/H. What is wrong here? "The Ta 152H-1 was among the fastest piston-engined fighters of the war, with a top speed comparable to the twin-engined Dornier Do 335. It was capable of 755 km/h (469 mph) at 13,500 m (44,300 ft) using the GM-1 nitrous oxide boost and 560 km/h (350 mph) at sea level using the MW 50 methanol-water boost.[7] It used the MW 50 system mainly for altitudes up to about 10,000 m (33,000 ft) and the GM-1 system for higher altitudes, although both systems could be engaged at the same time. Kurt Tank was flying an unarmed Ta 152H in late 1944 to a meeting at the Focke-Wulf plant in Cottbus when ground controllers warned him of two P-51 Mustangs. The enemy aircraft appeared behind Tank, but he escaped by applying full power and engaging the MW 50 boost "until they were no more than two dots on the horizon". (Souce: Wikipedia).

Ps: Not just the speed. What are the sources used to make so weak wings like this? At 750 to 800 km/h this plane starts to shake and threats to break wings at minimum effort in the joystick. It seems an early-war japanese plane. Damage of cannons are strange, a lot of shots needed, even with 30mm, to down a single enemy fighter. This game needs urgent verification of all the flight models and damage models. Moreover, the .50 caliber pierces easily the armor plate, even the 60mm glass-armor of 109s.

Note that you are reading indicated airspeed. Quite often performance is quoted as true airspeed.

Now assuming that the 410kph you're traveling at is actually calibrated (which isn't usually the case because the pressure field effects around the aircraft will affect the pitot reading, however the pitot appears to be on a wingtip boom on the ta 152 which means it sees reasonably cleanish airflow) I get a true airspeed of 725k0h at 11100m assuming a standard atmosphere.

Thank you for the explanation! Living and learning! I'm gonna edit the video, removing "broken performance" to "test performance".

In short.
1. It is possible that "3 minutes" will be like a engine modification, but I can't promise anything for now.
2. When I have time, I will look and re-check for information in the technical documentation for the this engine, but no changes have been planned yet.

Thank you,

the historical correct 3min for the DB605a would be certainly most welcomed and overdue.

FM report has already been submitted multiple times over the years with ample of sources:

 

thats been discussed now since 2018! in the FM section

Thank you Gavrick!!! And...... of course.... the biggest thanks for the_emperor for your effort to fix known bugs!!!!
