Police cars are overall slow as hell..

The old Caprices with the LT1s were very fast, they WOULD go 140 and do a 15 second quarter mile..

All the new police cars (stock) except for Camaro are almost exactly the same performance as their civilian counterparts.

Each year the Michigan State Police does a police car evaluation for all the police forces in the country to see as a benchmark..

the results are in this pdf file:

Page 4 in this pdf has the benchmarks for all current 2003 police package vehicles.

crown vics don't go faster then 128 even with the slightly revised engine they received in 2003, and chevy wimpalas are a front wheel drive police car LOL, not much power either.

Some wacky police departments may install superchargers but most do not as there is no need for it, even extreme programming wont make much difference in performance on these cars.

 

to make room for turbo

 

So to go past 100 I need turbo?

 

As long as you don't redline in fifth (assume you have a manual) at 100 or around it.

 

You mean my third gear I got auto

 

It wouldn't hurt . Try going downhill, too, lol.

 

Well no wonder you can't hit 100. But more horsepower never hurts.

 

Well I can HIT 100 but it stays there forever and it wont go past it.

 

I guess it's time for a former police officer to step in. I'm not sure what it's like in the States but I'd image it's much the same as here in Canada with some varying degrees but police cars are not supercharged or otherwise. The supsension and other parts have been beefed up but other than that, that's about it. Many of the vehicle run on propane instead of gasoline because of better combustion and throttle response as well as cleaner emmisions. Remember too that yes, they are usually heavey with computers, perhaps a cage and there parts.


As for the govenor in the P5. A friend of mine has been modding his and found a fuse that seems to be the govenor. He pulled it and according to the reading from the GPS the car tops out at about 245km/hr (153mi/hr). I haven't pulled mine yet but she tops out a 198km/hr (123mmi/hr).

 

Ive got mine to 125 it was doing 5500 rpms it never started cutting off I JUST RAN OUT OF ROAD

 

My car cuts out at 6700 rpm... I think that would make about 130 mph on my car.

I've only taken it to 120mph and then I ran out of road.

I know it cuts off at 6700 rpm because I've actually taken it that far on 4th gear, but not 5th.

 

Our Proteges are not limited to 155mph simply because there is no need to... they can't get there.
