R-R did add ADI to its Griffon, for Shackleton patrol bomber - max take-off boost, but AFAIR,
Packard with the P-51H,(& P-82?) - was the only R-R V12 powered fighter to use it..
Griffon-Spits being somewhat 'over-powered' weren't cleared to use max-boost for take off anyhow, unlike Tempests..
Was that not all about the landing gear?
Yes, the Griffon did get ADI for the Shackleton, very much post war. And the Packard V-1650-9 also got ADI.
