Hi,
Bingo!!! He has 400-500 rpm left, but he's already past peak HP (assuming the car is stock), so he's not going to make any more power with those extra spins. And, it's power, not spins, which beats the wind. Classic case really.
But don't lose sight of the fact that you cannot just continually add more power (except in theory). A Top Fuel Dragster making 6,000HP can't simply double it to go faster, there's a point where the trade-offs cease, trading off that is. More HP, stronger engine, more fuel , equals more weight, meaning even bigger engine, even more fuel, even more weight, and on and on.
There are engineering limits. These can, and have, been overcome, the Land Speed Record exceeding MACH1 for example, but these technological breakthroughs take years to solve and some never (at least to present) are...
Happy Motoring!... Jim'99
