Kev, I was under the impression that the Spit 16 performed better than the Spit 9. At least that's what I understood from sifting through all those Spit posts.
Depends -
Better than our current F IX at low alts (Merlin 266/66) worse than our current F IX at high alts (20k+).
Difference between the high alt Merlin 61 fitted to the F IX and the low alt Merlin 266 fitted to the LF XVI.
Merlin 266 was just an American built Merlin 66, so it performs identically to an LF IX.
Contrary to a previous post even at 5 mins 25lbs boost it is still NOWHERE near the performance of an La7.
Mk XVI with 25lbs boost (we're only getting 18lbs) is still sub 400mph (just) at any alt straight and level.
In fact at about 10k the Seafire III we are getting (18lbs) will be a very close competitor for the XVI.
