Bear with me, I've never owned a supercharged engine. Before pulling the engine I tested the compression using my Snap On tester, and got all at 100 psi after 3 cranks except for the one bad cylinder at 125 (I assume the water was sealing the rings better) and one cylinder at 90 PSI.
Are these acceptable numbers? I haven't found them in JTIS, so I'm not sure.

Here's a video of the poor cylinder test.

Hi,
Just seen thread, I had problem with holed piston (NO8) so no reading on that one but had 120-125 on all others (at least if i remember correctly and yes i have Nikasil bores)
As it turned out the piston was holed between top and second ring but good old Nikasil there was NO damage to the bore so 1 new piston and alls good.
regards
