VQ30DE - turbo compressor sizing

I was calculating some compressor maps for a member here who is planning on boosting a VQ and use the Excel document based on the VG from this site: http://www.mygen.com/users/dbruce/my...sor%20Maps.htm

I changed a few things around to try matching up with what the VQ should be close to like for instance 182.34 ci for the 2988 cc displacement and I put in a VE of 90% instead of the 80% used in the VG setup. I'm sure that's probably on the low side at some points in the rev range but I figured would be pretty close.

Basically I was just wanting to post this on here for some of you VQ gurus to kind of look over and possibly fix any mistakes I might have in there as I don't really know a whole lot about the VQ plus it might also help out some of the newer guys when trying to match up a good compressor.

Don't mind the names of the tabs and graphs and such. Some say VG30ET and other parts say VH45 from another graph I was working on. All of the numbers should be right for the VQ basing off of the parameters I used.
