Been trying to find the quickest way to get to 100mph in the FR.
At what RPMs should I change gears for optimum acceleration?

Sport mode overrevs like crazy going up to 7000/7500rpm on each gear from 3rd upwards. The car is listed as 148bhp@5800rpm.
But you need to go above the peak power otherwise the upshift will leave you too far down the rev range and therefore no longer in the power band?
The power band is not necessarily at the very top of the rev range. I had a Mazda 6 MPS which could easily go up to 7200rpm but the power band was at 6500rpm. So letting it go up those extra 700rpm was a waste of precious split-seconds.
I agree that bouncing off the rev limiter is rarely a good idea, but if those extra 700rpm means that you're higher up the power band after the shift, then you will have more power available overall.
Let me try and explain this better. Imagine a car with the following power;
50bhp at 1000rpm.
60bhp at 2000rpm.
70bhp at 3000rpm.
80bhp at 4000rpm. (Peak power)
70bhp at 5000rpm.
And a gear shift loses 2000 rpm. So shifting at peak power (80bhp) drops you down to 60bhp. If you shift at 5000rpm, you don't drop down so much in power (you drop to 70bhp rather than 60).
It's a rough example, and it would depend on what your car does after peak power. But most cars at least hold on to a decent percentage for a short time after peak.
Edit: I should also mention that it's probably the torque curve rather than the BHP curve that should be used in this way, but it's easier to explain power.

Frs Rev to 6500 anyway and not 7200 like cuprasdont they? ?
Sport mode or D are the same when WOT just sport will leave it sitting In Higher rpms so rpm. Heres a video of my mapped cupra doing 30-101mph changing Lol before redline, seems to work well for me.
