Hi all

not heard much in the way of this so bear with me if it has been discussed, i just haven't came across it.

When I hit 5k rpm, I get, what I would call an extra kick of power. I can only describe it as a turbo which is set to boost at 5k rpm; a lot more mild but its there. So what my question is, what happens around 5k RPM to have this extra kick of power?

I have a 2019 A10 GT.

Most modern engines have variable valve timing so valve opening is optimised to engine speed, at 5000 rpm the valve opening will advance allowing the fuel/air mixture and exhaust gasses to be inducted and expelled at the fastest possible speed

wait till you put a supercharger on, then its REALLY noticeable with good fuel and a good damper.
