I will have to go on my "car" laptop & pull down a log file. IIRC the pressure differential in/out is minimal & about average for aftermarket FMIC's. The temp delta on 1/4 mile runs against a base line is significant as well as on the street in normal driving. The logs in CSV format (excel) which I posted on N54tech.com show ambient & outlet temps by time & RPM.
There are a number of units with higher capacity but with my intended horsepower gain & desire to fit the cooler without cutting the shrouds or removing the bumper the ETS 5" unit was the best compromise. Install took me about an hour.
EDIT: Delta at the end of the run was 32 degrees.
