my friend has a 99 mustang gt, 4.6 automatic...
i have an 89 iroc with a 305tpi, and a 5 spd... 3.45 posi, dual cats, k&n's, flowmaster muffler, airfoil, few other things, but mostly stock
his mustang is COMPLETELY stock, and is a convertible,
i was going to race him last night, but my clutch is slipping BADLY, so after i get my new clutch today i will race him tonight, for some reason i think it'll be close, but i will win...
what do you guys think?

I am thinking that he will get you. It may end up being who the best driver is. Your best bet will be down low. Try and get a light or something. Before you do, make sure you get your launches down. Stall up to maybe 1500 rpm and then punch it - you may have to ease into it though. Let us know what happens! We're rootin for ya!

i have heard the automatics stangs are dogs, i think with a good launch and quick shifts you can take him. take all the extra weight out of your car like:
heavy stereo equip (subs, amps..)
back seats
tools
spare tire
jack
that should help give you more of an edge, give your car a tune up too.

Try 13.96 with nothing but welded in magnaflows and a K&N in an automatic '01 GT with 3/4 tank of gas

I think with the added weight of the 'vert and all though that 5-speed car ought to be really close to if not faster...it usually comes down to who gets the better launch on the street anyway.

I've raced the same '01 auto GT (not convt.), on three different occasions and have won all three. Wasn't even really close. My car ran 14.4's in the Spring but I've been modding all Summer so it's hard to say what it will run now. I do know for a fact that NHRA record holder Evan Smith ran a 13.91 in the Bullett which has the better intake and a 5-spd but it was in 90 degree heat. The same day he ran a 12.96 in a stock SS. At any rate it should be an interesting race none the less. I would say the fact that it's a auto and convt. should give you the nod.

everytime i have been at the track , the 4.6l stangs pull in low 15 second timeslips , i think it will be very very close you should probably be somewhere in the high 14s , but like everyone else has said , it depends on the driver , just dont miss any shifts , and i think you have a good good chance

I think its gonna be close, whoever gets the jump off the line is gonna win this one..with the added weight of the vert it'll make it more even.. just make sure you launch well

one of the guys on the boards test drove an automatic stang and said it was pretty slow, also doesnt the whole vert fact slow it down due to extra structural support stuff, and i have heard most auto stangs are slow. i think it will come down to if the camaro guy can drive a stick or not.

I pretty much have the same set up you do:
305TPI
5 speed
airfoil
3.45

anyways I've raced a few 4.6, stick and auto, and haven't been beaten yet. The sticks will be right with side by side, but the auto's, well I think my 88 Tempo could keep up.

I was at the Tasca Ford day at new england dragway the end of september and the stock newer gt's were running in the 15's all day long..Some cars made horrible showings..The only cars that put up any kind of impressive numbers were the fox body stangs,funny cars and one 1970 camaro with a ford 460 that ran a 7.7 at 177mph..In every class there was not one newer stang that made it to the last 3 races in it's class. From the numbers I saw I don't think you should have too much trouble taking out the stang..

The AOD/AODE stangs are pretty slow with the 2.40 first gear. The newer 99+ 4R70W Stangs have a 2.84 first gear from the factory which really helps out with these cars. The race weight in my father's GT was around 3580 with him, so I'd guess the 'vert is probably pushing around 3800...that'll definitely slow anything down.

Anything can happen in a "street race", but the '99 GT makes 240 rear wheel hp. '99 was a bad year for the Cobra, but a good year for the GT. Good luck, but I have personally seen a stock '99 GT run a 13.91 e.t. this summer.

A friend of mine has a 1999 GT convertable with an automatic. Her mods were, at the time, 3.73s, Exhaust, and drag radials. At Lebanon Valley Dragaway the car went consistant 14.2s and I think she actually won the Wednesday street series. On one occasion we saw her run at New England Dragaway and she layed down a 13.9 witht the same mods. Now the car has some tranny work, better tires and a Procharger running 12.0s.

This is true but the 5 speed in the Camaro has a 2.95 first gears which is lower and combined with the 4 other gears will probably help it to beat the mustang. The new mustangs and camaros are all overweight however and need to go on a diet so I think the Iroc has a slight advantage because the horspower difference is probably not that significant considering the camaro has a few mods and he started out with 230 hp and the mustang has 260hp.

PS Where did all these mustang guys come from?

Who cares..? We love fast american muscle cars. They love fast american muscle cars..I think that's all that really matters. When the ricers start coming then I think there will be something to worry about.

We come in peace. The point I'm trying to get across is that this GT convertible isn't a 15 second car unless the driver either leaves the traction control on or spins all the way through 1st gear.

by the way, i haven't run my car at the track yet, what do you think my 1/4 time would be?
...i'm THINKING anywhere from 14.5-14.8's

my mods are in my original post, i have a few other small mods, but i can't think of them now
thanks guyss...

btw what kind of improvement should i see after i get my exhaust this weekend...?(replacing dual cats with dual hi flow cats, and a hooker cat back)

I dont know why you are worried. The 01 mustang with an auto runs a 15.1. I saw two brand new ones at the track together, both hard tops, both 15.1x. Id imagine the convertable is even slower.
peace
p.s. I know one of the guys...no trac controll, no spinning

I would say it will be close, but the Stang should have the advantage. Now, if it were one of the 98's or earler(I think) then you would probably win, because I hear those things are high 14 cars at the very best.

I have seen the camaro's with the 305's run in the mid 15's with similar mods. The mustang 4.6's are dogs. At SIR last year there were a few of them 2000's and a 2001 and all 4 of them ran 16's. I think they were runing in the 16.2's. If you have never dragraced, I mean taking it to the track, it's hard to say who would win because a good driver can shave a good 1.0 sec. off his 1/4 mi times. When launching, bring the tires to the point of almost breaking traction...Almost. Good luck!

forgot to add, the guys that were running the mustangs at SIR. They could have been new drivers and not know what they were doing? I think one guy got into the 15.8's? I cant remember? I do rember racing a cobra,not sure what year? He ran a 14.4, almost 2 seconds behind me Hope he took a good look at the front end of my car because the only view he will ever see is the Tail Lights!

are you sure they weren't V6s. A while back in the Ford magazine they even got a brand new v6 5-speed to run a 14.9 at E-town. If a GT can't beat that, than the driver must be an import owner.

I watched an '01 Stang GT auto run 14.92 at the track, but, the guy had no idea how to drive. The next week I saw a different GT run 14.42. It all depends on who is driving. I have also watched an '01 Z28 run a 14.27 on slicks?!?! I would say it definitley depends on the driver.

It definatley depends upon the driver, 60 ft times, and even barometric pressure. I was not paying too much attention to them obviously. But 14.4 is kind of impressive for such a small engine.

14.4 sounds about right for a bone stock '01 GT w/auto trans. That's what ours was running in the early summer before the K&N and mufflers.

The '01 has a slightly higher CR than the '99-'00 model, which explains why they are running slightly faster.

i think the gt will win for real....my friend has a 99 auto gt and two of us were in the car and this guy with a modded up LT1 wanted to race...my friend shifted the tranny and we obliderated the LT1...no joke
i almost added a 89 fox body to my car list after that race....i was impressed
btw his 99 gt is auto, k&n, two flomaster mufflers and air silencer removed

Another factor in these Mustangs that seem to affect them is the temperature. I've seen 10+ horsepower gains just by cooling the one for 1 hour. For some reason these newer 4.6s are affected by heat badly.

I am a regular at the track and I have never seen a 01 Mustang pull high 13's with the mods Nic said. I know four people with 00 and 01 Mustangs. One of my friends has a supercharged 01 GT, along with a bunch of other mods, and he runs high 11's. My other friend has a stock GT aside from an exhaust, and his BEST time with something like a .700 r/t and a 2.0 60 ft is a 14.4. I don't remember the other times of the other 00 and 01 Stang, but they don't run 13's, and they have several modifications too. I've seen them race my friend's 1994 Trans Am and lose every single time. Oh, and I believe all the Stangs are stick.

Not knocking Stangs, but the new ones are damned slow as compared to the new F-Bodies...and even to the LT1's.

Oh, and Nic, I'm not trying to be a bastard, it's just I don't see how you get some of the times you do, and if you did, they have to be flukes, like that 12.96 in a stock SS. :P

The 12.96 in the stock SS was ran by Evan Smith. He races one of the index classes in either NHRA or IHRA along with being a writer for Muscle Mustangs and Fast Fords and yes, he's a damn good driver and provides an excellent example of what the LS1 is CAPABLE of. I doubt a writer for a Mustang magazine would need to embelish a timeslip on a competitor's vehicle. Take a trip over to LS1.com as there are a few others that have hit the 12 second mark straight off the showroom floor as well. By no means is that an indication that all of them will run 12's, just that there are a few that will.

The 13.96 in the '01 GT was ran by my father. I saw this run with my own 2 eyes. There's also a white '00 GT around here that has ran a 13.95 with a K&N and welded in flowmasters. Again, this is no indication that they will all run high 13's with these mods, but there's no excuse for a stock 99+ GT with an auto to run slower than a 14.60. I'm sure these 2 GT's I've mentioned are on the faster end of the spectrum for their mods, but again...this shows what these cars are CAPABLE of, not what they'll all do.

I don't mind you questioning me, but I've got no reason to lie or make anything up. None of these cars belong to me, so quite frankly if you go out and race them and beat them I don't car. Anytime you've got a ? feel free to ask me for a source.
