Ok so when I drive my car really hard the engine squeals, LOUD and like a pig. Its horrible. Its only when the car is on the road. Not a lift. And its only when the car is warmed. When it is off of a cold start the noise isn't there. The squeal only occurs from 5,000 rpm and above. And it only happens when i'm hammering down on it. Any idea?

Have you check the drive belts and tensioner?

Especially look for any contaminants, like oil or coolant, if you see any, clean all the pulleys with brake clean, let dry and find source of contamination.

Also have someone rev engine while you observe drive pulleys, look for any wobble in the pulleys.

If pulleys are OK, then try this:

Raise car, put on stands. Grasp tire and push/pull both horizontally and vertically, if any movement then possible wheel bearing, ball joint, tie rod, control arm bushing.

Check CV boots for any signs of leakage or cuts/rips in rubber boot.

It may be a bearing that is causing the squeal. If you find any movement after doing the above, then a bearing may be running dry.
