No doubt you're reaching those flow rates on high hp custom ITB motors. I should perhaps predicate that I was referring to injectors sufficient for the single plenum setups on both the single flap and VRAM Motronic manifolds, which is what I think the OP is referring to, which make max power around 6200 rpm and rev limit max at around 7000-7200. The data accumulated here is from years of dyno tuning 3.8 motors built and tested, some of which go into track cars or cars like the Singers, which were also dyno tuned and tested on Superflow engine dynos at Aasco's or Ed Pink Racing, and/or Dynojet chassis dynos, including all the Motronic 3.8s your shop has built and sent over the dyno data for custom programming. It could be that none of these 3.8s I've seen ever exceeded 340 hp, but so far I've never run into a Motronic 3.8 with 993 injectors where I've run out of injector flow to achieve target fuel AFRs while still leaving sufficient headroom.
