What is the best you can get out of a 1600 x flow

Standard cc

just over 100 bhp per litre, so your talking about 135 from a 1300 and perhaps 170 from a 1600,

maybe an absolute no expense spared ultimate spec engine might get a bit more

think i saw an article about a 1750 crosser with about 198bhp

[push rod]

Probably from the good old days when every crossflow was 1760cc when they are only +090 (1688cc) and they all had 140 bhp and twin 40's..
