hmmm, well a true overrev would blow your engine pretty much apart, its hard to say what damage you could have done, maybe nothing at all. the only advice i can really give you is to keep a good eye out for any other engine related problems tha may arrise in the next while, but i have a feeling your gonna be ok.

I dont think you really hurt your engine. Were you alreayd starting the turn ? How was the road surface? Were you already beginnign to break?

There is no way you could have over-revved if you were only doing 40mph and went from 4th to 2nd... You can do 15mph faster in 2nd.... unless you slammed on the gas...

I'f you let the clutch out a little too fast... with the higher rpms and the car did not have enough time to be slowed by the engine.

i think the chirp actually was a sign that you saved the car from certain damage

and no ive never gotten a chirp on a downshift, however im lucky enough not to miss a shift (knock on wood) or driven that hard to that extent

4th gear to 2nd at 40MPH will do no harm to your engine. I do it all the time around turns to spin tires around the corner, its fun .

Yep, the chirp is just your tires slowing to engine speed (braking your car). 40 in 2nd is like 4-5k rpm. Should do no noticeable damage.
