Sorry, but You didn't get what does cornering speed mean. Cornering speed doesn't depend on power (unless the car needs power slide to turn but let's say it behaves perfectly neutral) and it doesn't depend on traction either. The thing Lundefaret speaks about is lateral acceleration which the car can take in the corner. That depends on many factors, mainly weight of the car, center of gravity position, lateral tyre grip level (depending also on tyre sidewall stiffness), suspension setup (mainly rollbars) etc.Quote:

cornering speed depends on how much all of the above "blah blah blah look at me how shiny i am" you posted can the tyre take before is starts sliding...Quote:

For the part of a turn after the apex, when the driver applies throttle to accelerate away, you can have two situations. Either traction limited or power limited. For sure for certain corners more power will result to higher corner exit speed (i.e. faster overall corner speed), but in other corners it will have no influence.Quote:

Therefore even if You have the very same corner and the very same tyres never two different cars can reach absolutely same speed (even if they have same weight).
Cornering speed is not a corner exit speed. Imagine that as a speed on a fixed diameter circle.Quote:

I know, but this it the theoretical ideal situation that never happens in reality.Quote:

You're talking about tarmac stages on Cyprus kind of show, aren't You? Well, I prefer fast tarmac cars anyway, but that's only me.
