Best acceleration has the horsepower before the shift the same as the horsepower after the shift. So this will require shifting well past peak HP with a street car wide ratio gearbox.
For an example that comes to mind, early RX-7s made peak power at 6000, mostly made noise over 7000rpm... but best acceleration involved shifting at 7700, waaaaay past the engine's powerband.
This is why you want redline to be about 2000rpm higher than peak horsepower.

They also were raced in the AWD version for rally as well. Those ran to 10.5k rpms

Historic club racing video on R-comps looks maybe a hair slower than crapcan racing on DOT street tires these days.
