I beg to differ. My '06 Vic with 15k miles on it runs out of steam at around 125 MPH and if I remember correctly the IP package is nothing more than stiffer suspencion, bigger brakes and different gears in the transmittion. Also speeds are not correct after hitting triple digits I know because my car is equiped with GPS and the speeds differs drastically after about 115 MPH. Also you have to consider the extra weight that is carried in the car, I.E. light bar, cage, guns ( shotgun, rifle, non-leathal shotgun), paper work, flares, first aid equipment, fire extinguisher, stop-sticks, toughbook (laptop), printer, camera recoding system, riot gear, riot shield, chemical agent suits with all of the accesories and I could keep on going with more equipment that I could mention. Also the speedometer on the '06 and above PI vics only mark a top speed of 140 MPH on the dial with the red line starting at 5500 RPMs.
