My friends 2004 GT has BBK Shorty Headers, BBK Off Road H, Flowmaster Catback, 3:73 Gears, Hurst Billet Plus Shifter, BBK Cold Air Intake, 75mm BBK Throttle Body/Plenum, and UD pulleys.


My 2002 ws6 has a c-force clutch, Z06 flywheel, long tube headers, 85mm throttle body, smooth bellow slp, with k&n filter, and a computer chip, torch arm bar and pan handling bars, all polyurethane bushings, tranny mount and motor mounts.

We both have Nitto drag radials. We argue all the time but we both just got our cars and arent used to driving them, let alone racing them hard. Be honest with me, lol. We'll findout soon

 

You should be able to beat the mustang. Get some practice time!

 

he has no chance if u can drive

 

If you were stock Id still give you the edge from a roll! Just dont miss a gear or eat a taco between shifts and ur good

 

u will bust his ***!

 

I'm gonna feel bad for your buddy. Make sure u film it. Everyone here wants to see this

 

Yeah you should have him but practice your launch and take it to the track if possible. Not worth the ticket or the crap you will get from everyone else on here for racing on the street.

 

you'll eat that mustang..
my buddy had an 04 GT, bassani off road x, slp lm2, 315's with nt555r, k&n filter, 3.73's, p&p heads, and cams (dont remember specs), and dyno tuned.

I still beat him with a volant intake and magnaflow catback on 275's.

 

YOu'll beat him. (unless you're horrible at driving).


BTW - he really should get a custom tune (not a box tune). At the very least he should get his A/F checked out. I'd imagine he's running lean on the stock tune with those mods.

 

You'll win whether it's from a dig or roll. In either scenario, he may hang for a couple seconds, but then you'll pull on him hard.

 

my friend had almost identical setup on his mustang and it only trapped 100 on street tires. barely in 13s. after talking with a better tuner he said the shorty headers are worthless. you should trap like 107 or so. easy.

 

No need for any tune with his BS mods, those shorty headers weren't worth the trouble they where to put on, shorties on a 2v car add about 5-10rwhp long tubes add 15-20 and the car wakes up on the higher rpms like mad. The stock ECU will compensate for his mods you won't ever see one running very lean. His A/F ratio I bet it probably 12-13 range. That is what most run with those mods, the only time you need a tune on the stangs is if you want to run anything higher then a 125 shot, or you switch out cams. The computer is insanely forgiving. I used to work for Dallas Mustang, anything pre 04 picked up maybe 10-15rwhp(being generous) for anything with less then ported heads,cams and blower. The new 05 and up cars, you have no choice but to tune, if the computer sees anymore torque it starts going to fail safe mode,with a tune and the help eliminating the lag from the drive by wire those cars respond well to a tune, I have seen gains as high as 35-40rwhp from CAI and a tune, catback doesn't add anymore power.

 

We obviously have different opinions. I'm no stranger to stangs either and I'm well aware of the Shorties being worthless. I just didnt' want to get into the intricacies of the stang's setup as it isn't the OP's. neither of us can personally uarantee the stang in question will be fine on the A/F. Until that car is hooked up to a sniffer or a wideband no one will know and not all cars are the same. Do you really believe NE stangs only get 10-15rwhp full bolt on? Maybe I'm misunderstanding you. No offense, but you're not really telling me anything I don't already know regarding S197s. This certainly isn't my first rodeo.

I will say most of my experience is in 4V's, but my only point to getting a custom tune was to help wake up the car/mods. A fair amount of gains on stangs is in the tune, combined with the mods.

 

These cars should trap ~100mph stock. If your friend was nearly full bolt-on (~265rwhp) he should definitely be trapping more than 100mph.
A tune definitely helps bolt-on 2Vs. They will go lean without one.

 

And you don't have a "chip". You have a PCM and maybe it is tuned...... Anyway with a launch all he will see is your tailights getting smaller and smaller.......

 

a 2v trapping 100mph bone stock? i doubt that.

 

My 03 with a tune picked up 3rwhp..... I worked at DMP for quite a few years. 2v cars gain no real hp from a tune. My a/f was 12.5-12.1 throughout the band, with offroad x pipe, magnaflow catback, trick flow plenum and cold air, that was untuned. My experience in them was on the dyno, 4v cars do pick up quite a bit more power from a tune.

MPH I have seen alot of 2v cars stock trap 100mph, My friends 02gt trapped 99mph bone stock with 4500 miles at ennis. Again these cars on the dyno and at the track are about as consistant as a hooker on blow.

One of the stupids gains I have seen on mod motor cars is degreeing the stock cams, some of them come retarded as much as 3deg, some advanced a deg or so. Mine was retarded 2 deg, setting it to zero my car picked up 15rwhp untuned from stock cam!!!!!!!!!

 

The bolts ons he has, shorties, x pipe, cold air. Don't gain but 10-15, long tubes, cams, throttle body, plenum or intake swap you can make close to 300rwhp NA. Again I have yet to see a single N/A bolt on car come close to running lean with a wideband on the dyno and I watched hundreds. I am sure that some could run lean, but seeing it first hand and watching hundreds dynoed I havn't seen it. So yes I guess it could be possible to run lean with bolt ons with a 2v, that be said My other fox 91lx coupe with gt-40 iron heads, f cam, gt-40 intake, S trim with 10psi on a cold day with 36lb injectors with a **** maf on the a/f is at 12.2, this is a stock A9p, my car lays down 447hp and 459tq.

No disrespect to you, this is just my experience with them. I am 31yrs old and have owned and driven mustangs since i was 16. I know alot but damn sure don't know everything.

 

the ws6 will win easily even if the stang has every bolt-on. cam will even it up only asgainst a totally stock ls-1.


a 2001-2004 will trap 100 every time in a decent da. it isnt a new thing. it still loses like a turd.

 

my advice is to take it to the track and race yourself. stop worrying about your buddy's stang. who cares if you can/can't beat it?
