well take it for what's it's worth since I'm not a class racer but to Joe's point, it can be and is done with fast cars.
My MPR built Super Stock GT Firebird by all accounts IS a very good working nine second car that now has a 900+HP BBC under the hood, backed by a stock gear set turbo400. I'll go so far as to say it's the best working 9 second car in Division 1 running brackets, posting a best 60 foot of 1.17 and typical 60 foots are between 1.19 and 1.22 depending on weather and track and .09 slower when breaking the 60 foot clocks with the back tires.
FYI, back in October I decided to deep stage my Firebird mainly to see if I could.
Well after 3 hits, lowering my stage RPM and adjusting my front shocks for more wheelie, my reaction times were between -.004 and .022 launching at 2400 RPM. Will continue this exercise next season.
