I can cruise all out at 170MPH here in Germany, with motor roaring full tilt on the A bahn. Wouldn't you think highspeed driving on the A-bahn would affect Power steering, if you suspect excess heat from the headers. Just my 2 cents.
I would imagine a track with shorter straights would create less heat. Because you are on the accelator full throttle at every exit, downshifting and pushing the engine towards redline.

Aren'y you maintaining a somewhat constant level of throttle if you are cruising at 170mph.
