There is a book out there that has a bunch of Holset compressor maps. I don't want to buy the book just for the maps, but I can't find them anywhere else. I tried to enhance the picture as much as I could. Does anyone have this picture or map that can confirm what I'm seeing? It looks like the outlines for the map on the left goes as follows: HX50, HY55V, HX50 (?), HE541, and HX60.

Good book, buy it.
 
Thanks for the help! I suppose one can't have too many books on turbos or forced induction.
 
is it this book?
