What's your opinion of how the whistle sound effect is implemented? Can you hear a whistle sound with closed oil/intercooler flaps at 200 kts in the real thing? If not, at what flap condition/speed can you hear the whistling sound? I've yet to find a source that doesn't 100% disagree with how M3 has chosen to implement the effect so far. thx.

Thx GT. You'll also note above that there was an only 2 knots diff between auto lean and auto rich with all else being equal in my speed runs. I think the overarching point is that M3 is in the ballpark, same as what you found with your great F4U Corsair Real-Time Engine Diagnostics Data script, which folks can find here: https://www.digitalcombatsimulator.com/en/files/3346516/ One easy way to know is that when you start hearing the roller coaster clickety clack sound due to high MAP induced engine knock, engaging the water injection will stop the knocking within a few seconds.

Did it again with Auto Lean and MAP showed at 57" in the F2 view. You'll notice my velocity increased by 2 kts - almost got to M3's 306. null

I did some more testing and it's actually very close now (4 kts slower than expected) - at 1000 feet @ 11,142 lbs, no wind, auto rich and WEP engaged. I used the performance data for weight as the M3 chart does not include that parameter. Once the whistle effect is implemented with historical accuracy, we'll be just about there. nullimage.png

They reduced the F4U’s speed by about 7 knots in the latest update. Hopefully, this is just one step in a longer process to fine-tune its performance. I'm also hoping we see a credible Zero AI soon—especially since the real Zero was significantly slower than even the slightly slowed Corsair we have now.

My apologies. I'm sure you're not common.

I'm just curious @-Rudel-, has the decision been made to keep the whistling effect as is or have the devs just not gotten around to fixing or at least looking into it yet? Thx.

The link you provided is a legitimate webpage hosted by ibiblio.org, a well-known digital library and archive run by the University of North Carolina at Chapel Hill. The site is a reputable source for historical documents, particularly those related to military history. Great find! Edit: This link confirms authenticity - https://catalog.archives.gov/id/78294169

Looks great! Thx for your efforts.

The current implementation of the "enable water injection" key command does not affect MAP. At 1,000 feet and full throttle, MAP remains at 57", regardless of whether the key command is activated.

Thanks, never used that one before.

Go into F2 view and you'll see exact RPM and speed. I have it mapped for when I do tests like this that need exact values.

The key command is currently acting as the throttle detent's micro-switch. The broken wire graphic suggests this is a temporary implementation. I don't think "some guys" are getting extra knots - either everyone is, or no one is. Would be nice if M3 weighed in and explained what we're all seeing.

Yes, I do see an increase in speed. The issue is that the increase in power should be primarily the result of the expected increase in manifold pressure, which doesn't happen. It stays the same whether I "enable" the ADI system or not. Aside from the MP, all the other values are pretty much dead on. null

Are you referring to "Enable Water Injection"? If so, I have verified the mapping and when I press it, the manifold pressure doesn't change. That's not to say it's not working, just that that keystroke does nothing. From the real flight handbook:
