What mature Napier Sabre plans could give prewar Britain

A mature Sabre design and production instructions could accelerate powerful British fighters before the Second World War.

Question

How would mature Napier Sabre plans sent to prewar Britain affect the coming war?

Short answer

They could produce more powerful British fighters earlier, including improved land and naval aircraft.

Notes

A mature Napier Sabre and detailed construction instructions could give Britain much more powerful fighters by 1940. A Sabre-powered Fulmar might appear, or Firefly development could move forward. A Spitfire designed around the engine is another possibility. The hypothetical engine is a developed version whose early problems have been resolved.
