What's the difference between a Spit VB and a Spit LFVB besides supercharger?
At 240 kph, Spit VB = 13.5 -- Spit LFVB = 17.3 --- 128%
At 320 kph, Spit VB = 10.5 -- Spit LFVB = 15.5 --- 148%
At 400 kph, Spit VB = 3.8 -- Spit LFVB = 9.9 ------ 260%
At 430 kph, Spit VB = 0 -- Spit LFVB = 7 ----------- PWNED!
What % longer will the Spit VB take to reach 440 kph in level flight? If 50% longer is insane then what is forever?

Depends on the flavor of Mk Vb we're talking about; the early ('41) version has a bit less 'oomph' over all, the late ('42) version is essentially the same as the '43 clipped wing version with slightly less wing loading, and the Merlin 46 type has a different engine which is (I assume) optimized for high-medium alts.
Minor variations may be ascribed to my faults as a test pilot, or arbitrary decisions about averaging out the results of the four runs for a given type.
