what mods do they do to police cars to make them fast ?
or is it just a different engine from the civilian versions ?

>>28548459 (OP)
>make them fast
they're not fast. they're actually slow as fuck. 99% of times when someone gets caught running from the cops, they're either in an even shittier slower car, have no skill and can't drive well, or there's a helicopter.

>>28548459 (OP)
Radio communications and training. Think of an angry bee hive. Once you make them mad, you're running away from all the bees.

>>28548459 (OP)
removed speed limiter
tougher suspension so they can jump curbs
steelies so they dont take damage

I'd be interested to know, too.
Here's a lineup of 2021 Michigan police cars.
As you can see the only one that goes over 140mph is the twin turbo Ford PI SUV.
I'm reading form other places their PI SUVs will go 150 and the best police Chargers will do 155.
If you can find an empty highway not going toward a town and can do 160+ you can probably get away if you're faster than backup they haven't scanned your plate.

>>28548468
they have to be fast or else people will run away from them

>what mods do they do to police cars to make them fast ?
None. You have to be going very fucking fast to outrun another car, and in most cases they will just radio ahead and pick up the chase at another point.
Unless you have actual driving skills and can do double-pacing or 2x over the speed limit through an area, you're not outrunning shit.

>>28548459 (OP)
The "fast" ones are just base model sports cars with the limiter removed. Easy to outrun if you have an actual sports car
All the rest are slow AF and rely on suspect compliance, backup vehicles that are already a few miles ahead of the suspect, and/or helicopters

>>28548459 (OP)
Ive actually researched some of this....

It depends on manufacturer and varied wildly over the years.

Sometimes is mainly support components like larger fuse box and wiring/alternator for radios and lights. Larger radiator because they sit and idle for extended periods of time. But engine, drivetrain amd suspension are the same as civilian models.

But other manufacturers offer what boils down to a completely different vehicle.
The aforementioned components plus higher output engine. Beefier transmission internals. Upgraded suspension.

>historical information:
In the 50s, police forces just ordered the cheapest cars for patrol vehicles (because they were actual public servants and not road pirates).
Fleet vehicles are white because its the cheapest paint.
But replacement body panels are black primer because it covers the easiest (this doesnt make sense if youre playing with a box of crayons but just trust me- its because many paints are semi transparent and having light reflect back through makes a completely different shade so you kill the reflection with a black base).

So you have officer Bob out on patrol on his 1958 Chrysler and his fender gets banged up.
So he takes it to the motor pool.
Mechanic has a new fender delivered from the dealer and swaps it out before lunch.
But now its a white car with a black fender.
To prep it and paint means officer Bob will be without a patrol car for a couple days. So officer Bob just heads back out on patrol and figures they can paint it later.

Now.multiply this by 10,000 police precincts across the country and you have the birth of the standard "black & white" paint scheme on cop cars.
It became so common and easily identifiable to the public that it was adopted as a standard.

It's got a cop motor, a 440 cubic inch plant, it's got cop tires, cop suspensions, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas.

Don’t forget the quick release steering wheel.

I was browsing 4chan on my phone while driving (handsfree mode on) and a cop went past in the left lane and didn't see me or didn't care but FUG it made my heart sink. Just an hour ago. I hate cops. FUCK PIGS.

>>28548486
The fact that the Exploder is the fastest thing AND quickest thing on the list both surprises me but makes sense given AWD. What surprises me more is how close the Charger hangs despite being RWD.

>>28548528
>plus higher output engine
i know Chrysler in the 60s and 70s sometimes had engine options only available for police models. usually it was just shoving a 440 into a car where a regular buyer could only pick a 383 as the biggest option. Didn't happen often though, since most of their models you could pick the 440 anyway as a civilian. One I can remember off the top of my head is the 2 door sedan Plymouth Fury - those were the base model Fury I (Fury I, II and III) but the cop versions had thicker torsion bar suspension, the steering boxes had better road feel and they'd usually have 440s in them whereas from memory the civvie base models you could only get up to a 383 engine in them, or maybe even limited to the 318 engine.
Basically like that blues brothers meme.

>>28548459 (OP)
Isn't there a V8 charger police trim with AWD?

>>28548617
Before Ford had the "Interceptor" line up they had the "Police Power Package"

>>28548617
The Oldsmobile 442 started life as a "Police Apprehender Pursuit" package. GM didn't allow makes to put anything bigger than a 400ci engine in an intermediate at the time so they stuck with the Rocket 330 but IIRC bumped it up to the 400 the next year (and 455 by the end of the decade through various nefarious means).

>>28548486
man. to think that the dodge polara would be the fastest cop car for a looong time. depending on where you look the top speed was 146-149.6 mph. There's one or two stories of retired cops that were lucky enough to try it out for themselves and they said that the speedo kept climbing past 150...

>>28548630
God, I love fuselage body Chryslers. I don't care if they rusted like cheese and were half broken from the factory half the time. Those hips are sex.

>>28548459 (OP)
Most mods are to help with all the idling they do.

>>28548630
Post the video

>>28548623
Other modifications include the ability to leave the engine on with the car locked for a long time, lock the door as you move away and not allow the car to drive when FOB is far even if the engine is running, plus a different lock mechanism that blocks the rear doors from opening from both inside and outside.


The AWD 5.7 can easily be spotted by its unique magnesium alloy wheels, which were also never sold in civilian variants.
The V6 and the RWD 5.7 come with steelies and dog dishes.


Picrel is the AWD 5.7 - note the wheels and ground clearance.

>>28548607
>still holds the record of "most cars destroyed during filming"
No it doesn't.

>>28548644
wat

>>28548459 (OP)
The crown vic interceptor had a variety of mods but most of them were more endurance oriented. In fact some of them were shared with the fleet spec they used for taxis.

They were electronically limited to a higher speed than stock. I think had a different exhaust. Had a built suspension and high density driveline components. I think also transmission cooler and maybe an oil cooler.

It was not actually more powerful than a stock CV. Just had some tuning differences and a variety of durability and cooling upgrades

https://www.ford.com/police-vehicles/hybrid-utility/
they don't up the horsepower of police vehicles anymore generally. they do mod them to be slightly more crashworthy and the engines have modifications to help them idle for long periods of time without wearing out prematurely

>>28548903
>mods for idling
Wouldn't the auto start-stop "feature" actually be incredibly useful for police cars? You'd think they wouldn't have to do any special mods now that it's become standard on so many new cars

>>28548459 (OP)
bunch of expensive durability ect like $80,000 car. upgraded everything basically

>>28548704
>different lock mechanism that blocks the rear doors from opening from both inside and outside
i wonder if this is just a modification of the child lock mechanism typically found on the back doors of cars

>>28548906
they have radios and computers sucking power in the car, so higher power draw is typical. that might work with a hybrid if the motor battery could power the 12v system though

>>28548623
can't relieve this is the first post mentioning that it's AWD
they have fast takeoff cause cops just mash the acceleration and AWD keeps everything tidy
plus being a V8 mogs 90% of normal traffic already
outside of that they're not really that fast, and Explorers are extremely slow because of all their gear
CHP recently bought some durangos to keep up with people cutting up traffic in high performance cars

Police vehicles aren't fast, they're just "as fast" as the speedier cars people buy. The ford 3.5tt cop stuff has acceleration punch and the 5.7 awd chargers have it decent from 20mph to 80.

Anything with a 12:1 weight/power (real, with driver weight and at the wheels power) and unlocked speed limiter is going to be noticeably faster. Most police vehicles are locked to the 130s if I remember right.

>>28548615
Charger is V8, is why.

>>28548528
>because they used to be public servants
until bootleggers and street racers started just running away from them, forcing them to get faster cars. by the end of the 1960s, big block Plymouths and Fords were the norm. the 1969 Polara used by multiple highway patrol units was the fastest cop car in the world for a solid 30 years, clocked at 150mph in testing.

also, only California really used the black and white. other jurisdictions used a wide variety of colors, with blue and green being fairly common. the reason media always portrays cop cars as panda cars is because most media is made in Hollywood and Los Angeles uses the panda scheme. NYC for example used to use black and green, then switched to blue with white stripes in the 70s before inverting it to white with blue stripes in the early 00s. yet nobody ever makes cop cars look like that.

What kind of impact did the prevalence of hotrod bootlegging have on the police cars at the time?

>>28549021
A cop 5.7 awd weighs in at something like 4500 pounds and puts 320 to the wheels.
This puts a base model v6 camaro at an advantage, plus its a camaro.
But you arent getting away from cops unless your plate wasnt seen and you can drive fast enough and find some random spot to hide.

We all remember the stolen hellcat who was on the highway outrunning the chopper...til he ran out of gas.

>>28549091
it made them realize how shit crown vics were for anything but croozing to the donut shop, thus opening the law enforcement market to other options

>>28548459 (OP)
they are not,unless it's a flat empty desert highway you have to be skilled and going extremely fast to outrun another car even if it is a crown vic

>>28549183
You only need to be two turns or 1 exit ahead to get away. On the highway, that's only a 10-20 mph difference in top speed depending on how rural of a road you're talking. Off the highway, all you need are good tires and the sense to not spin out when exiting a turn.
If you're being chased by a helicopter then ggs lol, not even motorcyclists can escape them unless there's a forest on the side of the road

>>28549095
Traffic camera get you plates and you'll be busted anyway. Cops chasing bad guys at 100+ mph is unnecessary.

Like Jake said, cop tires are constructed different than normal tires.

>>28549241

>>28549243

>>28549250

>>28548486
god damn those are so fuckin slow

the way euros meme on north america of taking big block high displacement engines and passing it through the shittiest gearboxes so they make 150 horsepower is irrelevant now, but the meme of taking good powertrains and putting them on obese bloatmobiles with the aerodynamics of a brick wall so they are slow as base model jap econoboxes is never going to end

>>28548468
those new explorers are genuinely pretty fast

>>28549303
considering that cop cars have to carry things like radios, computers, the barrier/cage between the suspects and the cops, and depending on the agency, steel plates inside the doors and bullet resistant glass for slightly better protection against bullets, amongst other heavy shit that the cars they're often chasing don't really have to worry about, it could be worse

>>28548704
the Pursuit AWD 5.7 does NOT have alloy wheels, those are plastic caps over 10-hole steelies. They are slightly different steelies than civvy stock, being 18 inches instead of 17, afaik you can't get steelies on a civilian LX after '14 so they are still rather exclusive. But not alloy.

the difference in wheel type is because the AWD LX cars have thicker hubs with significantly less offset, requiring an entirely different wheel than the RWD cars.
also as an aside most of those cop features can be enabled on a civvy car using AlfaOBD.

one thing you forgot is the AWD 5.7 has the old 5-speed NAG1 transmission instead of the ZF8.

>>28548459 (OP)
I saw a police chase where they couldn't catch up with a fucking 1997 corolla or something like that.

My buddy bought a 2019 PI Explorer with the AWD. After taking 200 lbs of cop shit out of it, swapping an intake and downpipe, then getting a good tune, he’s making 750hp and getting low 10s. Things a fuckin beast

almost all police cars have Goodyear Eagle RS-A tires that are junk. I've seen some with upgraded bridgestones.

Police have flashing blue lights and that gives them a massive advantage in congested traffic but where they really shine is on the interstate, if you try to run by getting on the interstate you are done. The will just radio into infinity and you will always have a dept staged and ready to take over as you cross county and state lines. The way to actually run from the police is a curvy back road that YOU know very well and has many side roads to cut down. Another consideration is that 80% of cops will NOT blow thru stop signs and red lights in congested areas they will slow down to 10-20mph for those.

>>28549876
I had those tires, they are the slip and slide special. Milpitas PD also uses those shit tier RS-A tires on their Tahoes KEK.

>>28549876
people try to use the highway to get away just because speeeed but it's controlled access. they know every on and off ramp ahead. best thing to do is gtfo at the first or second exit after breaking line of sight then going into the back streets etc.

>>28549893
Is that not common knowledge at this point? Literally every video of swim cars running from cops has them jump on the highway for an exit or two, then jump off after the sirens go away and disappear behind a gas station or random alleyway

>>28549912
evidently not given the number of police chases on the news where people just stay on the highway
then again the news isn't going to cover ones that get away for obvious reasons

does anyone know what mods they had on 1st gen police crown vics/LTDs?

>>28550019
Cop brakes, cop transmission, cop engine, cop tires, and a cop suspension

>>28548459 (OP)
Depends on the department. My former job just bought regular cars and there were zero upgrades for performance. If anything, they were slower because of all the extra weight and drag. Spotlights, lightbars etc added extra drag. Cages and equipment add lots of weight.

This thing was slower than shit and handled terribly. I almost rolled it more than once.

>>28548475
This. It's marginal improvements all over the place, that YOU the taxpayer paid for, so that the average cop can be more fearless chasing your ass all over town. If he gets in an accident, he isn't paying the repair bill anyways, that once again falls on the taxpayer.

The Pursuit version had the 351 with the Variable Venturi carb, that was later mixture controlled with the Mixture Control Unit (VV/MCU), and had a C6. The Patrol units had whatever the going 5.0/AOD was in the Crown Vic that year. Both versions had dual exhaust and the small oil cooler that went at the base of the filter. CV Pursuits were rare to the point they're almost unheard of. If you go look up Michigan Sate Police tests you'll find the CV's were basically an also-ran compared to the Chryslers, who'd usually win, and Chevrolet, who'd usually have to go fix something about the package (frequently brake related) and retest to a suitable placement. Ford usually wouldn't do shit and keep putting the same thing out year after year.

>>28548459 (OP)
>what mods do they do to police cars to make them fast ?
None. They just buy cars that are reasonable fast to begin with and then add in weight in the form of gear they need so if anything they are slightly slower. Most cops aren't going to chase extremely high speeders, easier to just tag and wait or have a heli track them.

>>28550294
What about in terms of shocks and stuff? I need to replace the shocks on mine and I see they still have the heavy duty ones for sale, is that worth doing?

>>28550324
Those aren't things that you can look at and know for the most part, so I don't. At the time I just made the assumption that the cars would have had a heavy duty suspension like the GM's and Chryslers but time has taught me about assumptions like that. Ford was lazy about police offerings, in the 80's this was referred to as Special Service Vehicles, from around 1960 to 1997 when the last B-bodies went away and Ford was the only one left offering a full size bof sedan.

Anyway you'll need to get information on exactly how your car was outfitted by Ford. First place to start with something like that would be a Marti Report (1967-2020) though SSV cars may not necessarily be available that way. You'll have to ask.

>>28548459 (OP)
90% of cop cars arent even the performance trim level. everyone got mad our state troopers have mustangs but they're literally v6 mustangs. very rarely have i seen a v8 charger, the fastest common vehicles in the fleet are probably the tahoes. coordination and air support will get you faster than any single car.

>>28548876
people on cv forums asking top dollar for original unflashed police pcms beleiving they can get the full 260hp out of a 2v give me a good chuckle

>>28550505
>the fastest common vehicles in the fleet are probably the tahoes
A friend worked for Kingsville (TX) PD a few years back. His primary patrol vehicle was a Crown Vic that was sick and didn't run right yet he still vastly preferred it over the backup Tahoe that was way slower. His preferred spot for traffic enforcement was just over an overpass on Highway 77 northbound and the Tahoe was so slow it would pull him like a half mile beyond the "good" place for a stop in that section that he could get with the CV. There were a couple Chargers that ran rough, like collapsed engine mounts, but were also broke most of the time because lolnoparts

steelies are meant to take damage and not lose the bead, hitting a curb at 40 would shatter an alloy wheel with modern sidewall ratios, its all designed survivability. its why dirt track and other low buck racing typically run em they can get damaged and quickly replaced after hitting something instead of a whole corner of the car being destroyed like when an alloy or forged wheel grenades

>>28550324
>What about in terms of shocks and stuff?
Most likely nothing OEM is available. Most aftermarket stuff is so generic that unless you know who the oem supplier was, and even then, you still won't get a factory spec part. For shocks just get Bilsteins, they are bullet proof and are a proper damper, none of that 'twintube' bullshit.

>>28548876
>They were electronically limited to a higher speed than stock. I think had a different exhaust.

Owned 93 CVLX fag here.
Non tow aero packaged cars had single exhaust. Interceptors had dual. Easy junkyard swap since the 'Y' pipe on a single exhaust could be unbolted and replaced with an Interceptor 'H' pipe. The. you would only need to add the driver side muffler/tailpipe. Catalysts were in the head piping separate from the mid Y or H pipe.
Later HPP cars had dual exhaust but had resonators(glass packs) in the tailpipes. Interceptors did not.

Most civilian LXs had AL hoods and AL crash bars(bumpers) under the bumper covers. Interceptors(base model L)used steel.

P71(Vin for interceptors) had a lot of HD stuff but the car was already heavier than a normal LX. Spring/load rates were higher because the car was a pig.
Best to start with the lighter LX. Find a P71 PCM and Speedo from a junkyard. Put on dual exhaust and whala. Engine goes from 190 HP to 210HP along with eliminated speed limiter. Stock mufflers on all interceptors were YUGE suitcase type things. Ditch those to save weight.
For better acceleration ditch the 2.73:1 FD for 3.08 or 3.27s. I drove a lot on I5, kept the 2.73s for those sweet mpgs, it would easily get 30mpg doing 80.
Jmod the trans for better shifting.
Dunno about 98 up formal roof cars.

Don't expect 260HP out of the early 4.6.
Weight weenie it and have fun throwing it around. Always wanted to put the AL 4.6 block in to get the weight down.

>>28552060
yeah, I saw the bilstein shocks on rockauto, I'll probably get those when the time comes.

You wouldn't happen to know how to revive the rear air ride suspension, would you? I tried manually filling it up using an access valve next to the rear license plate slot but nothing happened.

>>28550531
>primary patrol vehicle was a Crown Vic that was sick and didn't run right yet he still vastly preferred it over the backup Tahoe that was way slower.

Ex 07 Tahoe PPV owner.
I picked up a low mileage unmolested non patrol 'Hoe.
Always heard these were 'slow'. I suspect one of three things.
The patrol units were heavily laden with equipment, more so than the CVs.
Or.
Officers were not trained or paid attention to what gear they were in.
Or.
Officers actually had the Tahoe SSV(park ranger mobile), which was just a stripped down Tahoe with the police package electrical ancillaries but not the power train goodness/speed capabilities.

6spd automatic shift points sucked. It always wanted to upshift and stayed in a higher gear.
Using the +/- button on the shifter stalk would get the PPV moving pretty good.
Peak torque was ~4200, peak hp was ~5500. Keep the engine within that power and, manumatically shifting, and the 'Hoe was pretty quick.
If the tires rolled after a stop it would quickly upshift to 2nd. Annoying. Slow down for a pothole doing 25, and get back on the throttle it would stay in 4th, give it some gas it would drop down to 2nd and launch, stupid.
It was really showing it's TH 700 roots.

Had to run the Goodyear RS-A tires anything else was trash.
Open road only ever got it to 137, supposedly 140 capable.
Surprisingly very steady at that speed for a brick.
CVs were pretty floaty past 125, it got interesting.

>>28552134
>You wouldn't happen to know how to revive the rear air ride suspension, would you?

Sorryanon, I specifically avoided the air ride cars because of their issues.

Bags were usually fine, it was usually the controller or a line would break/leak, which then the compressor would kill itself trying to fill a void.
Check the height sensors, bleed off solenoids and orings.
Unless you plan on towing or hauling a lot of cargo, just replace the bags with springs. Can't recall if the older wagon springs would work, if you need cargo capacity.

>>28552162
I may replace them with springs but I think the air ride thing is pretty cool so I'm going to see if I can figure it out.

I've already used the car to move houses, the trunk is so big I was able to smash a queen size mattress into it kek. I didn't even need to rent a uhaul this time
