Message: <blockquote data-quote="dolly" data-source="post: 366452" data-attributes="member: 1372">find the airflow ur engine will be pumping out at a certain rpm for a given engine displacement. just search at google, lots of online calculatorsthen for example you want to run at 1 bar of boost. so take ur calculated airflow (in cfm for the compressor map above) then multiply it by 2 (1 bar boost, effectively means you doubled the air)with this figure, plot it on the compressor map, follow the 1 bar y axis (2.0 pressure ratio) move along the x-axis (cfm) till you get the calculated airflow (after factoring in boost)this is best case scenario, ideally there would be some sort of losses but forget that first.Now that you have plotted ur airflow right, notice which efficiency area it falls in (higher is better)so for ex, for this map, at 1 bar boost, for peak efficiency, ur engine should pump around 400-450cfm (after factoring in 1bar boos and the rpm)do this for all rpms and see where they all fall, ideally you wouldn't want too many points to fall too far on the left or right, cause it'll just shorten ur turbo life ^^;. i could be wrong, so please correct me ya</blockquote>
