Napier Power Heritage has this to say, which is I think given the complete void in the engineering files about this power rating the most likely explanation:
They say the E.122 (which is marked on a projected power curve elsewhere on this thread at 3500ho) was the Sabre Mk8 - which never existed and as you can see below is a very different engine. It needed in principle +25lbs boost to get that figure it appears, I have never found a figure above +17.5lbs for any Sabre that ever existed under any conditions
with any form of water injection or anything else.
From Napier Power Heritage Trust website itself:
"The Sabre VIII (E122) Series engine of higher boost with 2 stage 3 speed Supercharger, contra rotating propellers and fan drive engine capable of 3,350 BHP was proposed but never built."
"The latest developments which include water / methanol injection have brought the maximum power output of the Series VII up to 3,055 BHP."

Happy now ? or are Napier Power Heritage Trust full of anti sleeve conspiracy theorists too ?![Man facepalming :man_facepalming: 🤦♂️](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f926-2642.png)

Sabre Engines with Bulk Injection carburettors
Sabre Engines with Bulk Injection carburettors The later Series IV Sabre engine was fitted with bulk injection carburettors. It had a single entry supercharger with strengthened supercharger and reduction gear drives to withstand the higher gross powers which result from the use of higher boost...
