Does any have a set of turbo compressor maps for various popular turbos, ideally with the max airflow and pressure ratio for the rev ranges of various engine displacements? The maps seem very hard to get hold of.
Thanks,

Best off asking on romraider.com i would think

 

How about here: http://www.not2fast.com/turbo/maps/all.html

 

Brilliant thank you both very much. All I need now is the airflow information from different engine displacements at different rpm to overlay on top. I think I can get this from my OBD reader for my 2.5.

Thanks again

 

all that info is purely a guide though -different engine configs and setups have very different reactions to different turbos,,much much better to use turbos that are proven with similar setups -new turbos are too expensive to have to buy twice
