Well, it looks like one of my SCP prayers have been answered!
Ran test, Results:

Top left two show the change in glow/spec stuff, top one is before, lower one is the test .exe.
Pair on right show a simular thing, with the lower one being the test .exe again.
Turrets did not fire though hull:D:yes:, but it seemed the number of turrets that can fire at one target has been reduced


Did sort a slight bug I've had with the new weapon effects, where the effect would be overlaid over the firing ship even when it should be (far bottom left). This is with existing .exe.
Also I recently used Lightspeeds Kasyer effect for these turrets, but the particles seemed to be produced off-centre. The new .exe fixed that.
New .exe did produce strange clipping of turret subobjects when over certain textures (bottom centre).
system specs:
1.1 ghz
128mb RAM
32bit Geforce 5200 pci card
Launcher v3.3
Now just get the number of turrets that can fire at a single target up (original was ~4), to about 8-10, sort out the issuses above, and I will be a very happy man...
