Increase RPM and power goes up? How does that happen? Unless you've extended the torque range it goes down, that's why you shift.
These engines love to rev: 0.
They love to rev like a slave loves to be whipped - makes them work harder and die sooner.
Higher RPM is for engineers who can't design cylinder heads - it's what's left when you can't do anything else.

You show total lack of knowledge when you say high rpms are for engineers who cannot design cylinder heads because high rpms is the only way to make the engine produce 120 - 125 HP/Liter of displacement. Simply put, a 4.0 Liter engine will never make 500 HP at 6000 rpm N/A no matter how you build the cylinder head. Period. Before you talk about torque, remember torque is a function of HP. HP is extrapolated from torque, The higher the torque at high rpm, the more HP it will generate.Then the gears spinning fast at those rpms multiply the torque over many times.
To give example of LFA, looking at the dyno curve even at over 9000 rpm LFA produces over 90% of its peak torque so it is the quickest when it is shifted close to the 9500 rpm rev limit. With short axle ratio (numerically higher), it can multiply torque the most at those engine speeds to get the maximum power for acceleration. Having a flat torque curve that stretches all the way to redline is what the engineers aim for in a high revving engine. It is not like the redline is chosen for show. Typically, engineers put a high redline because the car is designed to make a flat torque curve at those rpm before it starts nose diving.

Got it. When you have no factual argument and do not have a leg to stand on then mocking is the best option. It is one thing to have a personal preference for large displacement/low revving engines (or turbo engines), quite another to trash high-revving concept. I am sure all of those billions spent in R&D for high-revving engines for production cars and their racing teams by leading sports car manufacturers like Porsche should have engineers come and learn from you. .
