I used to have a ‘93 Porsche 911 - found that it needed to stay out of top gear (which was 6th) to get much acceleration out of it above about 110 MPH. It needed to stay in 5th to achieve top speed of (I think) 158 MPH, which put the engine at red line.
I only had it to 135 MPH - and only twice. The first time, alone in the car, I thought my heart was going to explode out of my chest.
The second time, I thought my wife was going to PULL it out of my chest.
Like I said, 200 MPH in any car is awesome - and not for the faint of heart or car.
