Yes and thanks agree, that the manufacturers chose not to use a gearbox between the 'H' and 'T', That is after all what I have been saying, and also that that means the 'H' and 'T' rotates at the same speed. As to a clutch between 'H' and 'T', at least you also came round to admit that it was permitted up to 2021 but according to your interpretations of the rules warding not from 2022. I have no prove that a clutch have ever been used, all I can say/was saying is it was permitted, If you have and can produce prove on here that it was never used I will appreciate it.
I can't prove that a clutching system was never used because I don't have direct knowledge of the power units.
The rule states that the MGUH must have a fixed speed ratio with the turbo.
Up to, and including, 2021 there was a clause that specifically allowed the MGUH to be clutched, but now there is not.
If a clutch is used, it s no longer a fixed ratio.
The problem with gearboxes and clutch systems in the turbo/MGUH is that it increases weight, rotational inertia, complexity and adds possible points of failure.
