Help with compressor map data.
 

Here is a spreadsheet that I drew up a few years back to help with various car related calculations.

Pretty crude as it was my first and only spreadsheet, regardless I'm looking for people with experience with various sized turbos on a 1.6 Miata: boost onset rpm, rpm at which atmospheric pressure is reached, and rpm for maximum boost, etc. to help me get an accurate data set for plotting turbos. Any educated guesses or empirical data relating to VE at different rpm points would be a HUGE help, as would BSFC.

Thanks

in for answer.

oh, and brg crew > *

there was a post a while back from andy floyd. something like end all debate on turbo spool or something like that. we all posted our rpm specific boost levels and spool rates and junk, might help you out.

I use .55-.6 for BSFC calcs.
