this diag depict Merlin without s/c (test on grd) and a DB with SC!

But it is true that Merlin had a superior TBO although I am not sure what the value were for the BoB period

So what figures do you propose for HP?

240 hrs was the BofB TBO figure for the Merlin. It was raised progressively to about 350 hrs by 1945, for combat aircraft.

Everywhere I look it's a 1150/75 value ON the Spitfire. What ever we think logic would ask for a lower value than the latter XX that is well documented (see my post for the Merlin XX on the Hurri)
