A more cost efficient use (cheap) is to cool the turbo with water/alcohol
>>  injection into the turbo inlet. The turbo really atomizes the liquid,
>>  causing it to evaporate rapidly, absorbing a lot of heat and volume,
thus
>>  reducing boost, which the turbo promptly replaces. This is very
efficient
>>  for street thrillers that don't need more than 10 seconds worth of WOT.

A SECOND I WOULDN"T DO THAT.    The cetrifical force blows it
to the walls anyway.  Use lots of pressure downstream of the the turbo.
