What does an 87-93 fox body run? I've always heard the best those damn things run stock is 14.9-15.0 but some dufous insists they run 13.9 stock, which would make it faster than every GT until 1999. I say this moron doesn't know what he's talking about. I've raced a few fox bodies, and quite a few 5.slows and have always beaten them. My best was a 14.6. Anyone know of any proof that a stock 87-93 Fox Body runs a 13.9?

Mark A Shields

Off the showroom, no way they run a 13.9.

GT's with 5 spd are good for mid 14s, autos high 14s/low 15s.

A notchack 5 spd, I would think, could pull a low 14 with the weight advantage over the GTs.

Don't you love it when asses like that guy automatically seem to know more than the books. Another case of blind ignorance. The type that makes you think you're a total genius. I've met guys like that too many times.
Here's some info, but you can take full stock in what Mark says so maybe its unneccessary.
I have read a comparison between a certain v8 Mustang vs a v8 Camaro from 84. They were both in the 16s. I don't know all of the info. I have books, though they are not beside me now, that mention the GT and the SVO running 15s. The most I have heard a factory Mustang--from those years--putting out is 225 hp or thereabouts.
In short, I don't see 13s, not even high ones without something being done. I mean this guy means magazine test driving, right? That kind of stock? No, sorry, don't think so.
Does he happen to own one? Does he have a relative or friend that has one? Is he planning to own one? I think that will answer the question of motive here. He's starting out with a better 1/4 mile time, so that his calculations, mods and all, will look better. That's my guess.

My friends 100% stock 93GT AOD was a 14.88@96.6 DEAD STOCK. Loaded full weight GT with 17" Chrome Cobra R's. A dead stock LX 5.0 could run a 13.9 if it had slicks. BUT...depends on if you mean Stock motor...or 100% stock car. With free mods and slicks...high 13's are easy. The AOD cars are alot slower then the 5spd 5.0's. My previous best was a 14.84@96 then swapped it out for a 5spd and ran times in my sig. NO other mods...PLUS added my stereo system! My 88LX hatch 5spd was a low 14 second car dead stock with 130,000+ miles. The magazines got crap times for them. I've seen stock times listed as a 15.5 before for a 5spd! Maybe if you miss a gear...or burn all through 1st! One main reason for bad times with the 5spd 5.0's is that some mags shifted way to high since the redline is 5900. But the optimal shift point is around 5000 stock..sometimes less than that. Anymore than that is revving for nothing. Off the showroom floor....13's are not happening though....if that is the question.

5.0 Mustangs are like a box of chocolates, you never know what you're going to get. Bone stock you're looking at anywhere from 14.0's (possible, but rare) with a 5-speed LX coupe to high 15's with an AOD 'vert. With the 10-minute tuneup (ie. bump the timing, adjust the tps, pull the air silencer/air filter, disconnect the swaybar end links, adjust tire pressures) 13.9's would be very possible in a 5 speed coupe with good driving, good air, and a well prepped track. Your average 87-93 5.0 is going to be in the mid to high 14 range stock. A buddy of mine has gone 13.8 in a stock coupe with the 10 min. tune-up and drag radials.

MdFormula350

sounds like i need some drag radials, because i want to run 13s..

Mark A Shields

But, I would say 99.5% out there couldn't hit 13s , they'd have to be one good driver. So, I wouldn't believe that guy from the first post.

Nic

Oh it would definitely take ideal conditions and an excellent driver to do it. Like I said, your average 87-93 5.0 is going to be in the mid to high 14 second range stock.

BuckeyeROC

One of my best friends has a 92 5.0L GT (manual tranny) and an 02 4.6L GT (manual tranny). The 5.0L used to get beat by my IROC when I was running 14.8's, so I think his is running low 15's with just a couple mods. The 02 is a lot quicker than the 5.0L, but you have to consider the milage on the 5.0L as well.

5.0mustang

My dads LX without removing the air silencer went 14.7 at 95! With tires and all the free mods it was going low 14s at LVD! My AOD was going 15.3-15.4 bone stock. I have heard of 100% stock ones going low 14s and even high 13s with nothing done to them. Some 87-88 coupes could hit a very high 13.9, but the majority are low to mid 14s! The average one will run 14.4-15.0!

But with little mods they can be made to run fast!

zerotosixtyV8

there is an obvious bias going on here, all the mustang guys are convinced they can run high 13s, I've never seen a 5.0 run better than a 14.4 without major mods. Can you please show me some evidence of a stock or even near stock 5.0 running 13s, even if it's a lame magazine?

Mark A Shields

That's also, cause they know more than the rest of us. And these guys have proven that they don't BS to me, so I believe them, but still like even Nic and I agree, your typical guy isn't going to get a notchback to hit 13.9 . Let alone a hatchback.

CHEVY_EATER

My car is heavier than stock(3440 lbs!) and runs high 13's on street tires. It is not heavily modded by no means. Still stock TB and MAF even! I have less than $1000 in mods with stock gears. I have a nice pile of time slips too. I can post alor of time slips from my car and my friends if you would like. My friends 88LX ran a 13.68@98.6 with just removed sway bar,off road H pipe,cat-back, and pulleys. Still has stock gears. This was with slicks too of course.

Go there and look. 14.07 at 99 with nothing but replacement 15" street tires (not a mod in my book!) and a module! I have a feeling that he could have seen a 13.9 with better conditions, especially with the 99 mph trap speed!

Go ahead and call BS, but before you do, realize that this is not my car, but another Mustang racers car, so I have to go with him! Also take a look at his high 11 second bolt-on Cobra!!!

zerotosixtyV8

that is not showroom stock, it was chipped and had Mickey THompson drags on it. still not a 13.9, close to a 14.1 actually, that's almost a car length

jocww

i heard that the saleens where pretty fast in the late 80s and the 93 cobras where suppose to walk alot of things

Hot Rod Lincoln

If you could find a STOCK 5.0 Mustang, they run low to mid 14's.

5.0mustang

First off the 99 mph he ran indicates that it could have very well gone 13s. With those times he must have pulled a 2.1 or worse 60', and street tired cars have seen 1.9s (he has seen 1.9s)! And I have a feeling this is NOT the fastest Mustang 5.0 out there! This was an example, and if a 14.0 @ 99 is not close enough and shows they can, than what do you want?

I could tell you about people I have heard do it, but you will call BS, so I tried to show you, and you say he couldn't under better conditions!

93 Cobra's had crappy cams which held them back quite a bit, but they could run 13s off the showroom floor! This being the case, the 1993 Cobra is a stock 5.0 that can run 13.9s without any mods!

5.0mustang

And with the 14.6, I have a feeling the 5.slows were either not trying to hard or what, because my car stock, with 2.73s and the AOD was trapping 93!!! Most 87-93 Mustangs are running faster then that, and you have never lost!!! SURE!

92Transam

I just have one question ( nothing to do with the topic) why are you non GM people here? No offence or anything just wondering.

IROC-Z5.7TPI

I dont think the fox-body got even close to the 13 sec range at all, but this guy was probably a rice-boy just trying to diss on your ***, you know how they do it... any way its

Mark A Shields

Cuz they know their cars suck and wish they had a 3rd Gen.



keep your friends close, but keep your enemies closer.

5.0mustang

Mark is right! It is true, i know the 5.0s suck and wish I had a 305 TBI, but i just can't afford one, so I am going to have to get a Grand national, or T-type!!! LOL

IROC-Z5.7TPI, the 5.0 Mustangs and L98 Fbodies were about equal as far as performance goes, but when you talk about the coupes, the Mustangs have a huge weight advantage!

Mark A Shields

That's why I bought one, then I popped the hood, and the damn thing only had 4 cylinders.

5.0mustang

Oh Mark, it is time to put some 10 holes on that beast!!! Otherwise it would make a great donar car for a stroker motor!!! *wink wink*

CHEVY_EATER

The chip was useless as he states. He had MT street tires!! NOT DRAGS! I believe he had MT Sportsmans on it...just a bias ply street tire with full tread depth. Not like a ET Street that is a slick with grooves in order to qualify as DOT class legal. BIG difference.

5.0mustang

Exactly, MT does make a street tire, and look with those tires his best 60' was a 1.9! That car if he never touched it would have gone 13s BONE STOCK, so basically the 5.0s can do it!

Graeme'sFirebird

ill be low 14's possibly high 13's with a 6al, x-pipe, and when i can replace my busted trac lock.. im running 14.5@ 94 w/ 2.4 60' right now, my only mods are 6al, king cobra clutch, and subframes. I also have 3 of the 4 stock cats clogged and a non functioning trac lock, and a failing stock fuel pump.. (ie: top end problems) :lala:

Edit- btw, im not biased..ive owned both, and am trying to get a 92 z pretty soon if money permits.

85transamtpi

I have heard of bone stock 5.0 fox bodies going 13.9.

But then again I have heard of bigfoot, unicorns, and UFO's.

The fastest I have seen a stock 5.0 run is low/mid 14's. I've also seen some run 15.5 or slower.

Keep in mind that there arent too many bone stock mustangs left on the streets. Everyones got some kind of mods.

All I know is, I got my *** handed to me by an '88 manual. Only known mod at the time was the guy just put on a new exhaust system. A week later I started changing a few things, first being getting rid of the 2.73 gears hehe. He started doing stuff too though From a rolling start of about 5 mph, I was able to stay with him in 1st but once he shifted to 2nd, he was pulling away. Later I found out my distributor's advance wasn't working and the carb wasn't adjusted properly. Still though if those things had been right, he would of blown me away anyway lol.

zerotosixtyV8

INDY S/S are classified as drag radials usable on the street, kinda like Nitto 555Rs, the point is, they are extra sticky tire compound and are usable on the street but can dramatically lower your E/T, hell, they took .3 seconds off my friends E/T, and he drives a torque-less RSX.

5.0mustang

Than why was his 60' so bad on them? With 99 mph on street tires he could have seen 13.9! I pulled a 2.05 (I was on DRs) and many street tired cars could do that or better, and I had the same trap as him! That car could have gone 13s without mods!

12sMustang

For those of you looking for proof, I'm trying to locate an old Cars Illustrated that has an article where they took Tony Defeo's 3.08 geared 87 LX hatchback, set it to factory specs, with air silencer in place, and pulled a 13.9.

This is not very common. In fact, the only options the guy had on the car was 3.08 gears, and rear window defrost, but it was still a hatch which is slower stock for stock than a coupe. Nevertheless it is proof of the 13 second non-Cobra fox-body.

Chris

Graeme'sFirebird

Well, theres the guy on stangnet too who has the 87 coupe, no mods but an h-pipe and advanced timing and is running 13's. all it will take us to get into deep 13's is exhaust and gears (5 speeds, no autos.. they take a little more):lala:

12sMustang

I think that they're talking about bone-stock 5.0s.

Chris

Graeme'sFirebird

I think i can get some websites of BONE STOCK 13's 5.0s. Only thing we need is traction.

Since most of you have never seen a stock 5.0 Mustang (or were too young to care), a 5 speed 87 5.0 Coupe was capable of high 13s off the showroom floor. The only third gen that could consistently beat them was a TTA, and I never saw one of those on the street . Pull the front sway bar, add some slicks,lose the silencer, bump the timing, gears and exhaust, and you'll be in the high 12s with a good driver...less than $1000 in today's dollars. Fox Mustangs hook a lot better than third gens,and they're lighter.

Graeme'sFirebird

On street tires, i cant get my fox to hook for crap! Ive been through 3 different sets of tires trying to hook, but nope.. Thirdgens had a more.. advanced i guess is the word, setup in the rear LCA's, Torque arm, and Panhard Rod are the way to go.. not the crap we have.

LT1guy

iTrader: (1)

F-bodies have the setup in the rear for handling, but not hooking....my coupe hooked pretty well on a mostly stock suspension (SSM lift bars, Lakewoods 90/10s front and 50/50 rears, and Nitto Drag Radials). Disconnecting your front sway bar and relocating your battery to the rear helps, too.

Graeme'sFirebird

On a side note, ive been playing with pulling my front sway bar, did you drive your coupe no roads and such with no front sway bar? any problems? I know you cant take turns fast and it takes common sense, but im more in straight line performance than twisties. Thanks

LT1guy

iTrader: (1)

I usually kept the front swaybar on while street driving, but that was more to keep the front drag struts under control than anything else. With stock struts its not bad, just don't push the car too hard in the turns. With my 95Z and 97 SS, I drove without a front swaybar most of the time (stock struts).

Nic

I've been driving around for 3 years with 90/10's, skinnies, and no front sway bar. Never had any problems.

Graeme'sFirebird

Mines coming off now.. thanks nic and LT1 guy :hail:

5.0mustang

I still have mine, but you probably wouldn't even notice it unless you drive like a maniac! At least there is another guy here that agrees 5.0s can go 12s on the stock motor!

With tires, they are better set-up just because Fbodies were designed to take turns, and they do that better than nearly any Mustang!

12sMustang

No, you'll definitely notice a difference even going around small turns or just turning from one street to another.

Chris

Nic

After a few days you get used to it and hardly even notice that it's not there anymore.

85transamtpi

All I have to say is LS1 + drag radials - sway bar = hook like hell.

I did that on my '85 trans am and it helped a bunch with my short times (2.0)

-Doug

12sMustang

Well, I sure haven't gotten used to it, yet. The thing has as much body roll, now, as my suburban.

Chris

Graeme'sFirebird

I took mine off, i love it.. the thing rides much better to me.. but then i AM used to suburbans.. i love it. The thing comes out of the whole MUCH better too.:lala:

12sMustang

Seems more like a caddy than a mustang on the road. It does seem to ride more smoothly without it.
