Current CVPI's come with a 200 amp alternator and an "idle meter" feature which monitors the battery voltage. If it drops below a certain level while parked and idling, such as on a traffic stop or on the scene of an accident for an extended period of time with all the emergency lights on, the computer automatically bumps the idle up to around 1200rpm to work on charging the battery back up. With the equipment in these cars now-a-days and the high amp loads being demanded, Ford came up with this idea and it seems to be working.

I work on police vehicles for a living and prior to the idle meter feature, we had departments coming in all the time needing new batteries & alternators. Since then, batteries haven't been an in-demand item.

the car and truck engines use different intake manifolds. otherwise, they are the same engine.. if you put a car intake engine in a truck, it will be a dog with no bottom end power.

I have a 2004 Ford Explorer XLT with a 4.6 V8 and I would like to put a better motor in it as far as a 4.6 goes what are my options for more horsepower and torque

Lots of misinformation in this thread. Start by searching P71 Crown Victoria and reading what Wikipedia has to say.

Highlignts:
Different tune than a normal crown vic
No PATS (chip key)
Higher ride height (stiffer springs)
Dual 2” Exhaust
Heavy front antisway bar
Light rear sway bar (unique to the P71)
200 A alternator and power points for Police equipment
Oil - Water engine oil cooler mounted behind rad in lower rad hose
Front bucket seats (cloth)
Vinyl rear seat
Rubber floor mat
Optional fire suppression
Steel in back of front seats
Trunk cargo divider
Diffferent interior lights in middle of roof
Calibrated speedo
Hour meter on newer cars
17” wheels
3.27 or 3.55 gears
Plain Jane black plastic dash and door panels
Manual heater controls (*****)
Marauder air intake with 80mm MAF sensor

The engine is otherwise a regular car SOHC 4.6. It is 260HP and 300ft-lbs.
