Injecting prior to turbo comp' impellers

If they are pushed way out of their efficiency islands then I'd start precomp injection a bit before they start getting outside the manufacturer's max boost intentions. But all this is experimental you see, we are all learning from our own (and those of others) mistakes. Hopefully.

This will be a single 50-trim Garrett/Mitsu hybrid turbo (Forced Performance "Green").

At higher boost levels on a 2.3L the compressor will definitely start moving out of its efficiency range. Looks like I'll inject with the post-intercooler nozzle first, and then at higher boost levels I'll kick on the pre-compressor nozzle to move back into a more efficient island on the compressor map. God, I love this stuff! :lol:
