[s-cars] water injection

[Philip Mische]

I have some experience with regard to the question about whether it's ok to
put the water injection nozzle ahead of the turbo.  In my misspent youth I
worked for a shop that did a lot of turbo development work.  We designed &
manufactured a separate supplementary fuel system which we also used for
water/methanol injection.  The supplemental injectors were (gasp) ahead of
the turbo - we never saw any excess wear on impeller blades.

And don't forget that back in the very old times, before fuel injection
ruled the earth, carburetors (remember them?) were more often than not out
ahead of the turbo, drawing the fuel and air right past the impeller...
