Will a State Trooper give me a lot of trouble if I get stopped for doing 150 mph in a 80-zone (on a freeway)?

You'll be arrested. Speeding eventually crosses a line into what is called "reckless driving." It's a criminal offense. Most speeding tickets are civil forfeitures, but only when we reach a certain line does it become criminal. I think it's usually around 25 MPH above the limit. I'm pretty sure 70MPH over the limit would do it.
