I'm trying to get hold of the compressor map for a Rotomaster T04B turbo (need it for megasquirt right?) but I can't find one anywhere. Don't really know what to do about it either! Turbos have .70 A/R compressor, but no markings (as far as I can tell) on the turbine, but it's noticeably smaller than the compressor.

Can I use an analogue if I get the right measurements from the turbo? Anyone point me in the right direction?

cheers

On the single turbo thread a guy has put a link for turbo calculator, if you scroll down it has compressor maps.
