[The HACK]

You have it all wrong. instead of attending a free-for-all on a go-kart track, you should look into a properly set up school like BMW CCA events with PROPER instruction rather than relying on a friend to teach you, IMO.

In a constant cornering state, adding throttle widens the radius, and easing off throttle or even braking reduces radius. Your concept of vehicle dynamics is backwards. LSD only sends power to the outside wheel when the inside wheel is slipping, and even then to get the car to rotate the LAST thing you want to do is to force the rear wheels to do the turning.

Without any of the basic skills to build speed upon you will eventually get to a point where you're going fast enough to wad up your car.

Lastly, the "line" for each corner is irrelevant. It's what your eyes tell you where you need to go. Yes there are ideal lines to go through each corner with, but if you don't already know the ideal line, whatever line you chose is probably going to be WRONG. Without training your eyes and brain to understand why you should pick a particular line through every corner, you will not achieve speed you crave. And this is where proper instruction is vital, if you don't know what the ideal line looks like, you won't know it until someone who actually knows shows it to you.
