compressor map (stock turbo)

[heelhooker]

Does anyone know where a compressor map for the stock turbo can be found?

I"m designing a water injection system. I need to know what efficiency the compressor is operating at to determine a suitable h2o flow rate.

yep in a search.

(just did a search on compressor map, the first two links I posted will be the most relevant).

cool. Thanks for the links.

With a compressor efficiency of .7, inlet temp of 27 C, and a pressure ratio of 2, I get a temperature increase of about 94 C...lots of room for improvement here.
