New to pi motors

[JC316]

Change the coils. My sisters 99GT needed them and it ran about a 7.5 0-60. The Bullitt might be slow, but it shouldn't' get dusted by a Maxima, especially with gears. Might do a compression test as well.

Check the cats

You may consider your expectations. If I remember correctly, Bullitt's only had about 10-15 HP over a GT. They weren't fast cars. And if you aren't used to 4.6 motors, they don't make power down low like a 5.0.

But if there is a problem, what's been stated above are places to start looking. I'll add to check your exhaust. My buddy bought a Mach I that was a turd. He pulled the H-pipe off and found that the cat material and broken up in to chunks and blocked the exhaust tubes.

Not use to the 4.6 but it's really down on power

Just stay away from Ford 1997-2004. Everything, IMO, was junk besides terminators, marauders and Mark Viii's

That makes more sense


I was looking at off road h pipes and will they all work on the bbk headers or are they brand specific when it comes to fitting the vehicle

I'd like to think driver mod has been done a while ago

As stated before, check the cats if they are clogged it will suffer big power losses. The off road pipe should work with any set of headers, and if the price is right you'd be more happy with the sound afterwards anyways.

Do a compression test, if you have a few weak cylinders it would cause it to be a real slug.

lol @ this qoute.

Put 410 gears in it

[4king]

I think it has gears just not sure what ratio, either that or the speedometer is just always over by 10mph

I'll take a look at the cats, to my knowledge all mods were done back in 03 before he bought the car so I would not be surprised if the at cooked

Thanks for the help

[ELVIS]

god bless.

Check the plugs and fuel filter

X2 clean air filter too....

[03silversnake]

Check compression should be about 150 on all an if that checks out good try running open header to see if it runs better cause I had same problem an found out cats were clogged. If not then change fuel filter check for vaccume leaks an litfters seem to go bad a lot also.

An if at 60mph in 5th ur at 60mph then u prob have 4.10s or just pull diff cover of an find out prob could use some fresh gear oil anyway

Eh? When the speedometer reads 72mph it meas I'm actually going 60

Crawl under the car and count the revolutions of the driveshaft in relation to axle turns.

[Big Pencil]

I had a 4.6 and it was total dog. Mods didn't help much either so I dumped it. Quickest way to semi-decent power seems to be with a supercharger on the 2 valve motor.

4king,

do you work at the O'reillys on beach street? I saw a Bullitt there yesterday
