Thanks for that link. Had some good info in it.
Well I've been doing some calculations on my own. I set up some graphs of the flow rate my engine needs at different boost levels. I used 80% VE and ambient temp of 85, and a comp. eff. of 74% just for a good average.
There are 6 graphs, one for 7, 15, 20, 22, and 25 psi.
I also put some lines on compressor maps of the 60-1, 62-1, to4e-46, and to4e-60. The colors represent different boost levels:
violet: 7psi
blue: 10psi
green: 15psi
yellow: 20psi
orange: 22psi
red: 25psi
The first vertical line of each color is the flow rate at 3000rpm, and the second is at 6000rpm.
What do you think? My motor is stock for now so I don't think I could get away with running much more than 15psi, but I have another motor just like it that I'll rebuild w/ forged lower compression ratio pistons once I figure out how low I need to make it. The stock ratio is 9:1. Which compressor would be a good match? The 46 has better low pressure/low speed eff., but the 60 has better high pressure/high speed. The 60-1 and 62-1 don't seem to be good matches since everything is to the left of the middle island.

Thanks.
