Car "A" 2100lbs 600hp @ 8500rpms Car "B" 2100lbs 600hp @ 6500rpms Both cars have identical transmissions. Both cars are geared to do precisely 200mph. Both cars are identical in EVERY way other than motor and the rear end necessary to hit 200mph. Assume bother cars have a fairly wide powerband (Turbo cars), just that Car "A" will have it shifted upwards as a side effect from the drastically higher rev limit. Which car hits 200mph in a shorter amount of time? Yes, i realize that it's hard to tell without a fully dyno graph, but too bad. Neither car actually exists, so i don't have graphs.
