When I had the stock rev limiter I would show an indicated 145mph. I am sure with the S/C and a 7600RPM limiter I can hit 155MPH. Anyone that would go over 150mph or so in a 'Tour is asking for trouble. The car is very well designed aerodynamically, but the ante-up is quite higher at those speeds. The air beneath the car becomes crucial and can cause more lift than the car has downforce. Your suspension loses some load and steering is affected. I don't know about you, but I would rather not lose steering at 150mph. I drive WAY TOO FAST most of the time, but I am very cautious not to exceed 120MPH (On a closed track, with an ambulance and fire truck on stand-by
).
BTW- I doubt any 'Tour, regardless of mods, can reach 180MPH. I do not think that the aerodynamics would allow, unless in a vaccuum.
