Does anyone have a source on AM-38 / AM-38F power curve?

[Laurelix]

Been looking everywhere and can't seem to find anything.

What also doesn't help is how AM-38F also ends up being called AM-38 in a vague manner

The same source as for the M-82 graph.

AM-38
1500hp at SL at military power
1600hp at SL at take off power
Better higher alt performance

AM-38F
1500hp at SL at military power
1700hp at SL at take off power
Worse high alt performance

What's been throwing me off is the fact Mig-3 here is listed with AM-38 engine whilst showing 1665hp

But it can't be the M-38F because the mig reaches max speed at 3400m

Then again…

It is specific regards to M-71 and M-71F which would mean it's just the normal AM-38

The performance difference between M-38 and M-38F was minimal - only by TO power:

You can find the power curves for both versions at p.8 and p.178. in the original manual for the AM-38 and AM-38F.
