However police Interceptors are juiced. Suspension is beefed by the factory frame is lightened, Transition shift points altered to get the most rev out of the motor before shift. They take out the rev limiter and throttle limiter. Now for the motor most if they are crown vic's start with a 250 hp v8 well you add the interceptor chip (that they take out before they took them auctions). The chip alters fuel to air ratio, timing delay, valve adjustment and so on) so with a lighter car and those mods you looking at say 400 hp. But its the rear end it the hat trick in 6th gear the rear end has a 1:3 ratio that means that for every one time the drive axle turns the wheels turn 3 times. In a normal car last gear is normally 1:1....get the idea.
