So this argument is basically a trade off of either:
keep the inlet pressurised but take a hit in turbine rpm - a la no DV
de pressurise inlet & maintain higher turbinerpm - a la DV
Would the individual turbo not also play a big part, larger slower spooling turbo would see more benefit to maintaining its rpm, compared to a turbo which can spool quickly & might lend itself more to maintaining pressure?
What about if you are at full boost/high rpm & just close the throttle to engine brake without a DV, surely that wouldn't be good?
