"Suction testing is one of the most exciting phases of any engine development program since we intentionally drive the pumps to the onset of cavitation. It’s important to know where that limit is, but cavitation can very quickly lead to RUD. Happy to report awesome results with better than expected margin, including this test which drove the engine all over the operating box. Go team - huge respect!"
