Although I don't understand what is the negative of dropping a gear at highway speed for passing. I thought it was the fun part.
It's not. But there is large appeal to having a wave of tq without the need to downshift.

It might not be so simple.

Ok, so power may fall off faster in an N20. But what if the N20 has enough of a power advantage over the N52 that it's fall off at redline equals the N52 at it's peak/

Basically if you study both cars on the same dyno at the same day, you may find that between 0-7000rpms, at NO point does an N52 make more power than an N20.

I am not SURE that's the case, but before we get caughtup in power fall-off, it's something to consider.
