Facelift To Maximize wheel power transfer

[Kery]

Anyone know the optimal upshifting RPM to maximize wheel power?
Up shfting at 6krpm(redzone) always maximize wheel power?

I think you're referring to torque. For example the maximum torque for the FL S3 is found between 1850 and 5300 RPM so in theory you're best shifting at 5300 and not 6000 RPM so you stay in the maximum torque band.

Higher gear ratio decrease torque transmitted to the wheel..
And also, the higher ratio the lower transmission efficiency.
But unlikes to Engines without turbo, the max torque appears in mid rpm range..
Im not sure when to change gear for tfsi..

Is thete any dynamo result of each gear ratio?

Try racing another S3 where you shift manually at 5300rpm and the other shifts at around 6.500rpm - you will not win that race

But @Kery doesn't mention if he has a diesel or petrol car. Below is with a S3 petrol car in mind.

Maximum engine power = maximum horsepower = maximum wheel power. It might be easier to understand if you convert horsepower to watt, 1hp = 746W. Our S3 is rated at 228kW 5800-6500rpm so to get the maximum power output you'll have to keep the rpm in that range.

Maximum torque is where the engine is most efficient and describes what you could call the "pulling-ability". In other words where each stroke of the engine is most efficient. But many inefficient strokes may be more powerfull than fewer efficient strokes which kind of describes the torque/horse power relation.
