That was me... :-)

We have done this for years,on all sorts of different set ups with no 
problems.By spraying onto the centre nut that holds the compressor wheel 
on,(usually a multi point nut),this stops the spray directly impinging on 
the compressor blades.Any thermal shock the shaft assembly suffers it seems 
able to cope with with impunity.

No,we spray a fairly large amount of water,or water / alcohol mix.The 
compressor never seems to mind.... ;-)
