how to make 97 gt fast(er)

Ryan441 · Feb 26, 2008

my mustang is slowwww. i got an o/r h pipe injectors, cam and intake and its just as fast as it was in the first place, i know theres more stuff todo but how do i get the stuff i have to work for now

SilverBullet00 · Feb 26, 2008

What all do you have done now... in more detail? You shouldnt need injectors. The best thing you can do is the PI head / intake swap, if you havent done so already. After that, its time for a blower.

98COBRA281 · Feb 26, 2008

GEARS 373s or 410s

riph22a · Feb 26, 2008

cam? what kind ?

rugster · Feb 26, 2008

PI cams are probably the cheapest route, see sig...

Ryan441 · Feb 27, 2008

i have herd alot that pi heads will make power but raise the compression to much for a charger. its a .495 .495 lift by .232 .232 duration, 23lbs injectors, no cats, air box takin off

Ryan441 · Feb 27, 2008

i just talked to a machine shop and they said to make the heads as badass as they could be it would be $550 and i would have to buy my own valve train, guy said that "alot of ppl do it the pi swap, thats good for about 40hp, the way im gonna do these heads, they be good for about 130hp, about the equalivalent of patriot stage 3s" idk whats true and not but sounds like the answer to my problem. what other parts besides the heads, intake manifold and i have a head replacing kit witch has dipstick tube, head gaskets, exhaust manifold gaskets, and head stud bolts

that doesnt sound like much of a cam a stock pi cam is .531/.504 242/252

97speedster · Feb 27, 2008

I gained almost a full second in the 1/4 mile by adding UDP's and an Aluminium flywheel.

are you sure ist not .431 cause mine sounds cammed out so that doesnt make sense.

how much of a difference does the fly wheel make. i herd the udp's add like 15hp

Flywheel made a huge difference the motors revs extremely fast and of course the huge weight difference.

Ryan441 · Feb 27, 2008

maybe ill do the pullies fly wheel sounds like a big job, how much does the stock one weigh

i think thats what the cam is advertised as

97speedster · Feb 27, 2008

I am unsure on the weight of the stock flywheel but my Fidanza weighs 12 lbs.

fobra559 · Feb 28, 2008

Get 4.10's! Pulleys and flywheel are not a bad idea either.

COramprat · Feb 28, 2008

Do you have it tuned? I didn't get the full effect of my mods until I had a dyno tune.

Not sure if you were asking me but no I have not gotten a tune yet waiting until I do my gears and aluminum driveline which will be as soon as my tax return gets here

bhuff30 · Feb 28, 2008

Define really slow? Have you run it in the 1/4 yet?

I've got a 97GT as well. Bone stock, it ran 14.67 at 94mph. I've only added an offroad H-pipe, and that made a nice difference taking me to 14.46@96mph. It has 145k miles, and a paper filter even. That's not painfully slow. You might want to look into regular maitence things, like cleaning/replacing the airfilter, changing the spark plugs, plug wires, fuel filter, and cleaning the MAF. These cars are kinda bad about getting the MAF dirty and causing issues. And of course get a custom tune so the AFs are steady from tip in to your highest shift point.

Ryan441 · Feb 28, 2008

maybe i just suck at driving lol, i ran 14.6 w/mine on bald tires. maybe i should take the cam out and put it back to stock but i think that the injectors will food it out so idk what todo,

oh and 3.73s or 4.10s?

btw sometimes i just cant keep it running at a light if im not playing w/ the trottle the whole time it will die and other times it idles fine

bhuff30 · Feb 28, 2008

Just make it run right with the parts you already have! How did you compensate for the bigger injectors? You should have either re-tuned the computer or gotten a matching larger MAF. If it won't even run right at idle, then you have major air-fuel ratio problems. You really just need to get this streighted out by getting it tuned!
