A bit of data is always good, beats the Facebook experts with their opinions
Although the kWs aren't anywhere near what you are after, it should give you a good indication.
I have Bosch 1480cc injectors, often called 1650cc (only when run at 4bar). I run mine at 3bar base so I don't thrash the fuel system.
Up top, making 437kW with boost dropping, injector duty is at 69% on E80 (might have had some residual 98RON in there)
