Hi Barry, 
I was definitely referring to compressor wheel probs..
 I agree with injection AFTER the turbo (and Intercooler).....
The thread originally mentioned injecting water/alky into
the turbo inlet... wait, I'll snip Tom S's original message:

True some indy cars made use of the squirt into the turbo inlet,
but they replaced compressor wheels often.  They were the "poster
child" example, used by turbo books, as for why you shouldn't do it.
