i think there is more to it than the cfm flow of the 2 different turbos.
air temperature and turbine size have a large effect on power output.
true, there are many variables to determine the efficiency of a turbo.
what really makes a difference is the
DENSITY RATIO.
a turbo can shove only so much air into a cubic inch before the ratio of compression becomes inefficient and causes air temperatures to rise. the hot air tends to expand more outwards after this point and needs to work harder to reach its goal.
different turbos have variable density ratios.
the variable between
1. pressure ratio,
atmospheric pressure 14.7 + boost pressure or psi = pressure ratio.
running 10 psi is a pressure ratio of 24.7 dawg
2. density ratio as i stated above.
3. airflow rate,
CFM
put all these together and you have your compressor efficiency map.
remember these can all vary depending on the motor, tunning, and altitude.
