Problem/bug with french Super Mystere B2 acceleration?

It take 3 seconds to just start moving after reaching 110% and then ~8sec to reach 10 km/h.
To compare with the basic 7.0 Me262 which reach 10km/h in 3-4 seconds.
262 has 1.8 tons of thrust, while Super Mystere has 4 tons with after burner.

Only got the compressor modification but it definitely won’t make a huge difference.

not really a bug, french engines are just really bad lmao (dont forget that super mystere is literally 50’s technology)


you can check thrust and such using WTRTI

Each engine has a different idle thrust and different speeds of gaining thrust from idle.
Super Mystere just takes longer to get to full thrust.

On the video you can clearly see the AB is fully ON when 110% are reached.

That’s not how engines work…
You don’t get instant thrust just cause you set the throttle.
The throttle is a power management tool, and the engine responds to its setting at its own pace, and that pace is set by the engineers of the engine.

But that doesn’t correlate with how much thrust it’s producing. WTRTI is a good tool that shows that.

Some engines (mostly early ones) take forever to spool up and begin to produce thrust. You see this very clearly on the A/Q-5s/Mig-19s, where they are very powerful engines that take 20+ seconds to produce max power when throttling up from idle.

It’s just a consequence of older tech.

The fire effect of the afterburner is purely visual.

Early supersonics accelerate slow

To be fair, the Me262 also was known to have quite slow throttle response IRL.

Also this reminds me of the bug from the past with the Napier Sabre engine where it literally took 10+ seconds to start making power from a stop in game.
