ok yesterday i finally got the chance to dyno my 04 Gt 5 spd with the mods listed in my sig...i have to say that im very happy.. i think i may have a factory freak :naka:

-Mike :icon_rr:

 

Seems a bit high, but not out of the question.

 

Yeah, I agree it's kinda high for intake/exhaust/pullies. It's a nice 30-35rwhp boost. Those numbers are about the same as the 99 Cobra made without the "fix", lol. Maybe your numbers aren't SAE corrected.

 

I believe you are right. Those are the STD numbers. No doubt still awesome man. Great job.

 

What shop around there has a dyno?

 

ive seen cars with more mods kick out 30 less hp to the wheels. congrats

 

I can definitly beleive those numbers as well. Here are mine and my mods to boot...

Mac Straight Shot w/ 85mm MAF, Accufab 75mm T/b and Elbow, Mac Prochamber and Flowpath Catback, FRPP 4.10 gear, Superchips Custom Dyno Tune, H&R Sport Springs, 2003 Cobra Front Bumper, White Face Gauges, Steeda Tri-Ax

Numbers were 273HP and 314Tq
People doubt mine as well but here is the dyno sheet too....

 

gtnumber2,
If you've seen some people kick out numbers at 228HP with more mods then those people were having some SERIOUS issues!! I have hardly ever seen any 1999 up Stang dyno under 225 BONE STOCK and I have seen a GOOD few!!

 

Hey, not to call bs, but those numbers cant be SAE corrected. Some cars with longtubes and cams dont pull those kind of numbers. Just a thought

 

the sae corrected numbers are only a fewless than the ones there..on thecomputer it said i put down 250hp and 293 torque..CORRECTED..

-Mike =)

 

honestly i think they bumped up the 04 gt without telling anybody there was an 02 there with moremods than I, had a steeda intake, x pipe with cats a diablo chip and flows cat-back..and he put down 10 less hp and 12 less torque...and Tunez is an 04 and his numbers are equally awesome..

i'm not complaining :icon_rr:

-Mike

 

Mine should be going on a Dynojet soon to double check the numbers. Mustang Dynos typically show lower numbers than Dynojets do and if that was the case, it definitly be a freak. I have run with a lightly modded LS1 camaro with no problems and outran a few. I know that many people say that should be no problem but in all honesty, those cars, are beasts. At the same time, I have seen a good few cars with numbers equally as impressive as mine are.

 

i spoke to a friend of mine at my shop who knows his stuff, he says that ford did change the GT slightly for 04 as they did they v6 (from 3.8 to 3.9) and that they didnt change the hp rating but they are making more around 275 hp CRank stock hp..who knew? :blob10:

-Mike

 

They made no changes between 00 and 04, same power. HP will vary from car to car. I made 250 rwhp through an automatic with similar mod's, mines an 02. Automatics typically makes 5% less rwhp due to drive train loss.
260 is very good for what mod's you have, you definatley got a good one from the factory. Should run real nice at the track. Low 13's with a good 60" time.

 

im really hoping to get deep into the 13's...my 14.3 run was ****ty because i couldnt take any air out of the tires..their compressor was broken and i dont think its a good idea to drive 150 miles home with 15 psi in my tires, so hopefully when i go this wensday i'll get soem good 13 sec passes, i might get my o/f x tomorrow if eveyrthing goes well

-Mike ccasion1

 

You better if you're making that much power! Good luck.

 

yeah i pretty much have the same mods plus gears. and i am only pulling a 13.5 at 103. it could be faster but i was racing with 245 45 eagle gatorbacks with 18 or 20 psi in them i forget its been a few months since i been at the track. and some guy posted his dyno numbers and the weight of his car is only 3200 lbs. when i weighed mine it was 3340 without spare tire and tank on empty and a fully gutted 99-04 mustang should be at about 3000 lbs??? ive checked my track times to my vehicle weight with me in it online and it showed that my car has about the same amount of horsepower that you are pushing.

 

Your car weighs 3240lbs?!? uhmm, sorry to dissapoint you there, but a factory freak is one thing, but uh...NO! you have like 15peak hp in mods and thats to the crank...sorry, but unless you didn't notice a 50shot that they hid in your trunk then I am calling :3some: Well, you guys dont have a "BS" smiley on this forum, but this one is freakin awesome!

 

dude, you're out numbered, there's two guys here with dyno sheets.....
-Mike :thefinger

 

I'm guessing that you are obviously lost to think that my mods will only net 15hp AT THE CRANK of all things. A simple chip or plug in programmer has netted close to 10-15 at the WHEELS alone. I have all of my listed mods and a custom dyno tune to boot. Not only that, if you want to complain and try to disprove my numbers, then tell me how I can reduce a video's size and I will post up a dyno vid for you so you can see it happening first hand. In other words, don't be angry because you weren't one of the lucky ones out of many who have hit numbers that high with similar mods, be happy for those who were that lucky....

 

LOL, omg, I'm not saying that YOU are not being truthful, I am simply saying that the results of the dyno are obviously very skewed. Mac Straight Shot w/ 85mm MAF, Accufab 75mm T/b and Elbow, Mac Prochamber and Flowpath Catback, and Superchips Custom Dyno Tune does NOT add up, im sorry, but it doesn't. I have seen hundreds of dyno's of my motor and that simply has never happened EVER and you are the SOLE exception. Does that sound like it is possible that you may have a dyno there that was a little off? Or are you so thick headed that you believe anything that you see printed and cannot except the obvious fact that something WAS wrong? How much weight reduction have you done to your car?? You have it listed at 300lbs less than my car weighs, how could you possibly strip that much weight unless you have the car completely stripped without A/C and all?? Your numbers are high because you gave them the wrong weight for your car, period.. And for you who jump in and give your $.02, I have not been disrepectful at all and the fact that you take it that way is not my problem, so talk to someone other than me.

That is some good HP #'s. With all my mods done to my car I've only gotten a pull of 244 HP to the rear. and 267 for torque. and that is SAE corrected.

 

exactly, LOL, the best engine builders out there are barely pulling 340-350rwhp out of an N/A GT without drastically changing CR.. With the "factory freaks" though, who knows what they could do. I mean geez, they could probly break 400rwhp N/A with your stock cams right I'm done with this thread though, unsubscribing I am just giving you a hard time by the way, hopefully you don't get too upset with me :angry4:
Bryan

 

what do you mean by lightly modded like k&n filter or something like my friends car. he has TA ls1 and it is sporting these mods: mac headers,mac o/r y pipe, borla exhaust, and the slp snorkle with k&n filter. his car has hit a 12.7 at 110. even if my car had a tune and drag radials i would still not even keep up with that.

 

look at the top right of the picture

 

Different cars make different amounts of power. Those are pretty good numbers for those mods. Unfortunately, you can't race a dyno or the numbers they produce. Which leaves them to be nothing more than that..numbers. I let my car prove itself at the track...that is my "dyno" :toothy10:

BTW my race weight is 3300lbs


Adam

 

nice, is that with you in it too? That is a pretty damn nice time, nothin better than breakin a new barrier. What all you have done anyways?

 

Yep...me in it. Stock 2001 heads/intake, VT Stage 1 cams, FRPP shorties, O/R x-pipe, Flows, pulleys, K/N filter <-----(most of the power comes from this) Thats pretty much it. Oh I have a PI3800 stall and 4:10's which aren't exactly "power" mods....I'd call them track mods. I don't make near the power alot of you guys do in this thread. You can dyno 500rwhp, but if you can't put it down to the ground, might as well be 100. I dynoed 247/271.

Adam

 

247hp after the cams?? wow, your cams alone should have put you there, what was your a/f? Do you have a graph, i would love to see it. Also, what were your 60's that run and MPH at the end. Also kinda tires you run? Thats cool man, I have a set of the stage II's on the way, just need to get the springs next check and they are gonna be ready to go

 

First off, I am not getting a bit mad at you. I do find it odd that the "best" engine builders are only getting 240-250 out of normally aspirated GT's. Not sure what they are doing wrong but if a factory GT dyno's 225-230 at the wheels and they can do all of the bolt ons and not produce but 15-20 HP increases, they may need to look into new jobs. I have seen numbers much closer to 260-270 time and time again with U/D pullies, timing advance, intake, T/B, plenum, headers, mid pipe, and cat back alone. Add in a custom tune and they get a bit better than that. Needless to say that the T/A is worthless with a tune though because you can do it electronically through the tune. All those are pretty easy to acheive with a non factory freak GT. Take a factory freak and the numbers have been there easily all the while, but not too often. My base line dyno before all parts was 230 hp and that is by far NOT an uncommon number. Also keeping in mind that depending on where you live and the conditions at the time can make a big difference as well. I am still going to run it on a Dynojet to get a comparison set of numbers on it as well though just to see.

Like I said before, no anger from me. I love to "debate" about this stuff......
