reading maps is a valuable skill. For those of you who know, what we looking are at, explain it to us.

hm... the garrett site does a decent job but it will take a few extra reads for me to get it totally worked out

thanks

Yeah I had to read it a couple of times to even remotely get some of the concepts LOL. That is just a basic filler though I'd still post up any questions you have after that.

I remember a while ago, someone had done up a program that plotted the compressor map and did all the math based on given standards of an SR.

EDIT: I thought I remembered a spreadsheet program being on Enthalpy's site. http://www.rs-enthalpy.com/tun...h.xls You'll need MS Excel to use it.

thanks hijacker that excel doc is loaded...

basically is pressure ratio vs lbs/min

so its total boost divided by the rate of air flow...
