Pre turbo injection during off boost theory.

[Revhead]

Im made to understand that spray pre-turbo can be beneficial as it increases the turbocharger's compressor efficiency.

Now, in most cases, water is only injected when on-boost.

I was thinking, what if water sprayed from the water injection's jet escapes to a nearby recirculating blow off valve, which blows the excess air back to the turbo's inlet during off boost..Will be there any effect or benefits?


Cheers.
