    Most of the Spitfire V Merlin 45 data has maximum boost is 9 lb. or 16 lb. What date was the 9 lb. boost increased to 16 lb., or 12 lb.? :?:

    My favorite Spitfire site Spitfire Performance Testing

    Boost (lb/sq.in.)

    (i) Max. for climbing (normal rating)(1 hr. limit) +9
    (ii) Max. for all-out level flight (normal rating)(5 minute limit) +9
    (iii) Max. for all-out level in special emergency (prior to increase to +16) +12
    (iv) Max. for climb and level flight (combat rating)(3 min. limit) +16


    Whan date was special emergency +12 boost used?


    Thank you!

    Have a look at "Merlin 40 series performance" on page 3, there's quite a lot of info on this subject there.
