the key to attacking cornering is weight transfer, especially with AWD. when you enter an apex, lift off the throttle or jab the brake to induce an oversteer, then power out of it to keep control. if you are powering into an apex you will understeer or turn all wide like some grandma backing her buick out of a parking spot.
if you oversteer too much power out of it, because if you slow down more or brake then you spin out.
if you are a little more sideways than you want to be, be aware of you countersteering. little steering input is better than too much. otherwise if you are steering too much, by the time the car straightens out, you are steered the opposite direction and you endup with a snap oversteer.
BUT, snap oversteer can be an advantage when transitioning from consecutive opposite turns, so long as you are doing it on purpose.
you cannot force the car sideways with the throttle alone without some sort of weight transition to the front using throttle lift off or quick jabs of the brake. its simple physics. put down the video games and get on the track, if you really want to learn how a car actually handles.
i have never been to an auto-x, but i drive a car every day. these techniques work just fine for me
how well your braking and steering is will determine your times more so than how much power your car has or your rpm. unless you want to be making laps in 1st gear all day because you can't keep the car moving around corners. keep the car moving and you wont have to shift to an impossible first gear or lug around in 2nd because first is impossible
