Is this where I renew my membership in the Flat Earth Society? lol!
C'mon, Shiv already posted the numbers. If you want to verify the flow capacity of this pump there's plenty of other platforms that have pushed the limits of this pump.
It's no secret that running two pumps inline will boost the capacty beyond the range of a single pump. That's why the stock BMW fuel system runs two pumps inline. The first pump raises the pressure so the second pump doesn't have to work as hard. Here's some good data showing how various pumps gain flow when combined in parallel and series configurations;
