I'm hoping I can squeeze 300-325 range with the tuning, but around here it'll be the fastest 2v for sure...

Me too, but I am more interested in the 1/4 mile ET and the 1/2 mile top speed and the 1 mile speed. I have been at this long enough to know it is way faster on my stretch of test road than the day I bought it 2 1/2 months ago.
Dual cone a CAI
78 MM Throttle Body and Intake plenum, could tell a huge difference as soon as I got it on the road!
Off Road X-Pipe
Magnaflow 40'mufflers
Heavy Duty Plug wires, don't remember the size, and spark plugs.
Bama 93% Race Tune
Change to 3:73 Gears, Automatic trans.
I know it doesn't add HP but suspension work that there is no wheel hop
This is all on a 2004 GT that I think weighs 3270 lbs.
Thanks

Without head work you probably won't reach the 320 mark.

Most full bolt on and cammed 2v cars make around 300

I have drag raced maybe twenty different cars over the last thirty years and have been real active the last three years with a high .13 second to a low .12 second one and I might be wrong but I swear my Mustang with the bolt ons and the rear gear change I believe that it will run a 12.5 to 12.80 right as it sits right now, is that possible?
The thing I enjoy the most is top end speed, I hold six Landspeed records and I plan on ruining in three 1/2 mile events and make 4 or 5 runs at each event. I really need to or want to run 130-135 in the half mile and then next fall after I add a supercharger maybe 150-155 Mph. Am I way off base or am I close?
Thanks

lol good luck with that 1/2 mile stuff in a 5 speed. You aren't even supposed to go wot in 5th gear. And you would be lucky to get 300rwhp without heads. I think you might dyno 280ish.

And 1/4 mile. Maybe with really good tires and a damn good driver to get mid 12s in the 1/4 with bolt ons.

EBay Bluetooth obd and torque software for android if you enter ur specs properly i.e. everyone underestimate their weight then ull get accurate 1/4 1/8 60ft 0-60 0-100 GeForce late hp/tq. Results between the software and my local chassis dyno were only 7hp off with the software being low

I weighed it on scales at a steel plant that are calibrated twice per year and it was actually 3230 w/o me in it. The manufacturers specs is where 3270 lbs. comes from and I understand in 2005 the weight went up quite a bit.
Farther up on a post someone said he didn't know about running the 1/2 and 1 mile events, if I understood him correctly you shouldn't run a Mustang at wot in 5th gear. I have a 95 Corvette that will run aa day at wot in 5th or 6th gear. Why did they put overdrive manual transmissions in a GT Mustang if you couldn't use it but I don't know where that came from because mine is an automatic transmission anyway. I won't run my first laps at the Dragstrip until the end of next month and I will run the 1st half mile event at the end of May but on the strip of road that I use to test on it doesn't shift into 3rd until after it crosses the 1/2 mile line.
I can't begin to guess how many passes I have made down the 1/4 mile and now 1/8th mile but I could safely say well over 1500 and mostly in 4-speed cars. People would buy a new RoadRunner or Camaro etc. and want me to make a few runs to see what it would do and I ran an 11 second car in the very early 70's for a Dodge and Plymouth dealership at four different tracks.
This has been a great forum since I bought my Mustang and started on it and everyone has been helpful but looks like I went to the wrong spot when I came to this one and asked for some help.,evidently there are only a few people capable of having and driving a fast Mustang.
I withdraw my question!:

no most people don't ever grasp what a truly 'fast' car really is. They point to times and hp and all this noise. I was reading one thread about gears where the guy was giving the quarter mile times in the 13+ second rage with 111+mph. That is low 12's all day long. I've actually held a nhra competition license in the 90's because my mustang(junkyard refugee*mm&ff sept 96 page72* and JRII) went 9.99 and 9.98 at the 96 97 and 98 true street events. I am not sure about the whole not running in high gear thing myself i've done it my whole life as well especially in my cars running with 4:10 and 4:56 gears its just a higher than 1:1 ratio is all.

I am suprised you car is really only 3300lbs from my experience they always underestimate them. I guess thats not the case with these. I stand by my statement though torque is a great piece of software, has track recorders with video recording gps overlay, heads up display capability as well as full obd code control and clearing

I agree and a lot of people that have never gone down the track much will think there car is really faster than it really is. I have raved a 400 HP 409ci. Impala and a 427/390hp Impala with factory 4:11 rear gear and 4-speed, 360 hp 4-speedCorvettes and they wer all 13.8 to 14.4 cars and then the Dodge Dealership car, 440 magnum, radical cam, fender headers, 4:10 rear gear automatic and eventually 2-4barrels on tunnel wedge intake that I am not sure the lowest it ever ran but my Brother says that I beat Raymond Beadle in the Blue Max Mustang probably one year or maybe two before he went to Funny Cars and always was one of the fastest in the country. I think he died a few months ago. Oh, I forgot my Brother thought I was in the low 11'S maybe a 11.3.
I also hold six landspeed racing records, I was mentioned several times and the very first few sentences were about me in HotRod Magazine three years ago in July and earlier a publication that a lot of people don't get The Bonneville News did a two page article about me.
I certainly don't know everything about Hotrodding and fast cars ans especially not a Mustangs that why I am here but I have been around the block before and one more thing I ran 60laps around Atlanta Motor Speedway with the last ten avg. around 172 MPH. Was probably 180 or better down the straights.

My 01 weighed 3335 on the scale. That's also with a bunch of added suspension parts, probably 70ish pounds worth. Subframe connectors, Panhard bar, Torque Arm alone is probably half of the gain, harness bar inside, and a half tank.

I'm expecting to cut out around 80-100 pounds over summer also.
