Our previous build of stock blower and stock bottom end and 200 shot of nitrous; ran 8.7 at ~1500 whp and made over 100 passes on that setup and won tons of events.
Your statements are from a limited source of data and comes from a Hellcat Community and not from the larger Race Community. Hellcat Community is about 5 to 6 years behind the Racing Community. Ford and Chevy have been in the low 6's and might be into the 5's now for their late model cars. Hellcats just got into the 6's this January.
To include, your data source is coming from tuners/shop owners that never used the best ECU software on the market = FuelTech and have never been apart of the racing community.
We made tons of changes (that we're not disclosing at this time) to make this build work just like the racing community.
NOTE....These records are for stock chassis and not full blow tube chassis cars.
Quickest/Fastest Hellcat
CHARGER record is at 7.7 and we're going to break that record
Quickest/Fastest Hellcat Challenger is at 6.9

Jake Sampson built this block and strengthen it to hold 2000+ whp and we did some other things to spin the crank over 8000 rpm.
Rossler built this TH400 to hold 2400 whp but curb weight is critical on failure
Turbo Lag - we need to stop using these cookie cutter TT kits (off the shelf kits) and build custom TT builds like the racing community. Thus you are correct, from a cookie cutter kit the smaller turbos will not lag. But look at the piping and how they route the hot and cold side. Those kits don't make sense for adding more power, larger turbos = lag
See picture below on how Jack (Jack Fab Performance) built this 76mm TT: No Lag and watch the FuelTech video; turbos spoil in under 4 seconds for launching the car
76mm Harts Turbo - we selected Harts 76mm because we do not want to stress the turbos at 99% to make the power. Thus we're using larger turbos and only racing at 60% capacity of the turbo. Thus limiting parts failure and longer life.
