Turbo compressor maps

Postby rowly747 » Wed Jun 12, 2013 2:41 pm

Hello I have this excel spreadsheet which will help you plot a compressor graph on the compressor map for a Garret VNT1749V turbo but unsure how to use properly.

Where does the AFR come from, smoke map or turbo map?
How do we estimate the efficeincy?

Thanks

Hello

I think AFR is "target AFR".

But, should be related desired boost pressure with MAF?

Could be useful to add "compressor efficiency" in the calculations.
