Just looking at the Davies Craig pump again.
Can someone check my analysis of these 2 different graphs?

Supposing we have 5 psi of head pressure (Wild guessing there so obviously it is a variable...) then the EBP40 will flow ~25 l/minute or 1500 lph.

The Bosch will flow 1000 lph at ~350 hectopascal which is 5psi. So at 5 psi the Davies Craig will flow 50% more? Am I looking at this correctly?

At ~6.5 psi the Bosch flows ~600 lph while the Davies Craig flows ~1320 lph? Here it flows 2x than the Bosch?

So the DC will really outflow the Bosch at higher pressures if I am looking at this right. Any way to measure or guess the head pressure? I know I have a LOT!!!! of 90 degree elbows unfortunately.

By the way I'm also working on logging pre-intercooler IAT with this device

I believe I can log directly to an 05+ ECU's rear O2 sensor circuit.

And finally, changing out a couple of double 90s for formed hoses.
