Re: Injecting prior to turbo comp' impellers
Yes, this is an intercooled setup. True - I've been more than happy with my intake temps when injecting only post-IC, so hardly any gains here.
It's still puzzling for me that no gains in aiflow are seen due to expected backpressure drop. I follow your logics above re. minimized engine losses, so probably there are gains in power output even despite unchanged air consumption, but I still would expect at least some (probably faint, but still) air consumption increase if there is any change in engine flow characteristics when injecting pre-turbo.
Anyway, I have now my car back from the workshop, so more testing in the next days. The photos of the compressor wheel have been made also to see if there will be any wear. I will also have my car custom mapped by the end of the month so will see if any gains are seen on the dyno.
