I just bought a 1996 crown vic pi. It was a detective car. It has around 127,000 miles on it.

What can I do to make the car accelerate faster off the line?

There's a cold-air article someplace here that really goes over what can and can't be done to these cars.

Usually changing the rear-end up to a 3.55 ratio won't effect the computer and gives you a kick in the butt acceleration. Mileage suffers a little, but talk about surprise a Ponycar when a CV burns rubber.

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.

1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.

13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane

I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter

.PLANS:: engine upgrade, 5.4L 2v stroker, rebuild interior in leather w/ buckets, thinking about turbos

I thought recent CVPIs came with 3.55s. If not, and you really want acceleration, put in some .3.73s.
I put a K&N filter in my 2006, and it seems a bit better. A good cat-back exhaust will help also.
Good luck.
