overflows. they said 600gph from a 1" but i proved that wrong.
That's because you used 90s and other angles! An overflow by definition is a straight pipe that runs from the dt's surface through a whole in the bottom straight into the sump. Then 600g might be possible. The more you divert the flow the bigger the diameter has to be.
You probably can't find and numbers on flow rate because there's a lot of variables to consider in a DIY project. Then people normally add a ball valve to adjust it to their needs. Get the flow right, make it silent and so on. Then it gets impossible to pass on the exact setting to any fellow DIY'ers
I know I'm not helping a lot but I do think you're doing a great job! Btw, LOVE the bike
