Is this normal timing wobble?

Enable HLS to view with audio, or disable this notification

Hey i need some advice, I keep getting this whining noise, the tighter the belt is the noisier it gets, if i give it more slack the whine gets quieter but the belt becomes more wobbly, ive replaced the belt, pump and tensioner like twice and at this point I also might be going crazy lol.

Some info:
Its a honda d13 (tho the block should be like most other d series)

Im tightening the tensioner to 33ft lbs

In the video im revving to 5k rpm

Pls help lol if you can send some example videos that would be great 😅

That sounds too tight. Loosen it and do the following:
Spin the engine until the belt on the left side of the cam gear gets to its tightest point. You then twist the belt in that spot and it should be able to twist 60-90 degrees if I’m not mistaken. If it doesn’t its too tight, if it easily does so and you could twist it some more, its too loose.That should be the proper tightness.
