What can a 1989 Mustang 5.0 automatic do in the 1/4 mile? typical 60' times? I know they have 225hp and 300 ft/lb of torque but I don't know how quick they really are. Anybody have some specs or seen them at the track?

I'm talking about the automatic not manual.

oh and sorry bout the ot subject.

mid 14s is my guess.

but you rarely see stock ones at the track and those cars react real well to mods.

My guess would be about 15-flat.

That's a good guess. Most I've seen do anywhere from 14.9-15.2 stock. Then 5spds aren't that much faster in the same year. Mid 14s stock. Of course it takes a very good driver to get anything better than mid 14s in a 5spd.

John had one at broadway performance for repair last week. Random shut off problems.

Fast no, but it sure does sound mean hahahahahaha
Paul stop racing sports cars, you should race me since we both have familiy sedans. Loser pays for the Donuts

Ant

TheMax95

wait who said anything about a race? I was just curious. lol

Your Vr4 vs my Max. hmmmmm I dunno Ant my Max weighs close to nothing. lol My guess is you'll have about 40-45 cars on me by the 1/4 mile. But I still have a feeling. hahahaha

Stock, the 5.0's are nothing special. However, you all know its soooo easy to modify those into beasts. I had a run with a modified 5.0 once and he just blew me away. It was from a roll too, so he didnt even have the torque advantage. Definatly can be mean cars. But they're ugly

I agree. As i grew up, my buddies all had 5.0's. With intake,headers and exhaust they reacted pretty good. Then they would swap the gears larger throttle bodies and cams. Those cars can be hooked up fairly easy and can get pretty fast.

dude your car has a more unique look than many MAXs ive seen on here. i EVEN like your tailights!!! thats only the second Max I have conceded to liking altezzas on. other one being brotherdelos' max.

I LIKE IT!

you've made it to the rank of one of my cardomain "friends"....a bunch of MAXs I think are really sweet.

you ever 1/4 mi your car? should be low 14s............

TheMax95

what about just intake and gutted cats with straight pipes? Would that be a huge difference over stock? Would it hang with say a 96 5speed max with i/y?

According to Car and Driver, a stock 1989 Mustang GT runs 15.2@92 in the 1/4mi. That's 5spd though. I'd make sure the car is stock though. You never know with Mustangs. There's a guy out here who races in an old LX body but has a cobra engine. Total sleeper.

Thanks. I havent ran the 1/4 yet. Waiting till it gets a little cooler down here in Texas.

TheMax95, I dont really think those mods would effect it much. Its the header replacements and full exhaust that really wake that motor up. If you've ever seen stock 5.0 shorty headers, there pretty puny.
A Gutted cat doesnt really make any big horse power. Ive even heard it can take away some being that the exhaust is not as free flowing due to it bouncing around the hollowed out cat before it exits.

TheMax95

In 1989, the gt and the 5.0 lx were not the same. The gt did run low 15s but the 5.0 ran mid-14s manual. I'm asking about the 5.0 auto.

If you're 100% sure he's stock. At Englishtown, NJ, he can probably run 15.2 in the winter. But if he does weight reduction, timing advance, gears, cams, or anything else that's hidden, then he'll run MUCH faster.

But on street tires and not slicks, he will run only low 15s at best.

my friend who has a 90 5.0 automatic with intake and H pipe did 15.8 at the track, I did 15.6 the same night with just an intake. There dogs off the line, but pull nice in 3rd gear/highway. The 5spds are much faster, the stock auto trannie shifts very slow and is geared very high...(1st gear redlines at like 60-65MPH)

Good info. What track did you run at? Is it sea level?

After doing a little research on stock auto 5.0s, I found out there must be a big difference between the 89,90 and the 92,93s. Cause you can check out www.car-stats.com and look up your car. Lots of manual 5.0s were doing low 15s. That must mean the autos do high 15s stock.

Isn't that wierd. All my friends in high school had 5.0s and they ALL modded them. So when I saw one run at the track on street tires, he was doing low 14s with an auto. But come to think of it, it had shift kit, gears, cams, Hpipe, intake, and flowmasters and it could only do 14 flat while spinning down the track. This is at sea level. So, if you're sure he's a stock 89 LX Auto, at best, you should see him do low 15s. That's with a few tinkering mods that they are capable of.

this was at ceical (sp?) county, MD, prob close to sea level. come to think of it, i think it's a 91 or 92, i'm really not sure, oh and it's convertable, so that will really slow it down. e claims he's hit 14's, but i don't know. If he can get 14's i can to without a slipping clutch

Aaron92SE

iTrader: (128)

If he has hit 14s, then he's not stock. He's done some weight reduction, timing advance, and many other little tinkering things you can do to a 5.0. He's not stock if he runs high 14s in a convertible auto. He might claims he's stock, but it's not in the same condition as it rolled of the show room floor. That's why you need to be extra careful in determining if it's stock or not.

Maxtank

I think he just had the intake at that point, i'm not sure, he may have just been trying to say hes faster than me? He has been having some problems with it lately tho.

Yup my buddy had a plain jane LX body 5.0 with a few mods and that thing was a monster on street slicks!!

Dave B

Most 5.0 (GT/LX) automatics had super long 2.73 gears. Team that long rear gear with the super long 1st and 2nd gears, and you'll see why these cars are a bit doggy in auto form. Simply adding a set of 4.10 gears and a higher stall torque converter will take the stock 5.0 (assuming good condition) from mid 15s to around mid 14s. Start tapping into the 5.0 and the performance is limitless.


Dave

Yeah my buddy in his 5.Slow (95, last year) has a few mods done... timing advance, shorty headers, Xpipe, dumped flowmasters, UDP and me and him are pretty neck and neck till we hit the end of 2nd gear and into third where he pulls slightly, about one car.

BTW, i only have an intake, Ypipe, exhuast, and i dont spray against him...

Once you throw in Cams and gears, it REALLY wakes those cars up...

Correct me if I'm wrong, and I very well may be, but the old Mustang LX was a 4 banger and the old Mustang GT was a 5.0 only. So there was a 4, 6, and 8 cylinder Stang. The 5.0(GT) manual could maybe break high 14's but mid 14's stock is pushing it a little. The 5.0's aren't as fast as people make it out to be. It sounds faster than it is. I'm sure the auto ran mid to high 15's.

99Maxima5sp

No, the LX i know for a fact could be had as a V-8, maybe a 4banger as well. The LX was the lighter of the 5.0stangs, while the GT was the more porky (more options) of the V-8s..

And no, the Fox Body never had a 6cylinder option, just a 2.3 (i believe) 4banger/Turbo, and a 5.0L V-8. I believe it was the SN95 stang that introduced the good ole' 3.8L pushrod V-6...

Ahhh, I see. What size was the turbo on the 4bangers?

TheMax95

a turbo stang?!? WOW, I am really clueless. I had no idea about that

iTrader: (3)

ya i heard about the 4 banger stangs... dont think there are many around, but i've heard of them

Aaron92SE

iTrader: (128)

50% of those generation Stangs are 4 bangers. One simple way to determine it is the look for a single ugly looking exhaust tip hanging downward. If it has two tips and you hear a nice rumble, you better be ready for anything. Sleeper 5.0s are everywhere. Almost like coming across a HB Civic in Vegas or SoCal.

bigdo26

iTrader: (3)

There's a sleeper 5.0 here at school - twin turbo. guess he dyno'd at around 550 hp!! Get to meet the guy and car next week

99Maxima5sp

Yeah, the SVO mustang was built from 1984-86. It was a turbo 2.3L 8vavle SOHC 4-banger pushing 14PSI (on the 84-85) and 15PSI (85.5-86 model). The 84-85 model had 175hp/210lbft compared to the normal 90hp, while the 85.5 model had 205hp/248lbft, and the 86 had 200hp/240lbft. It was a T-3 turbo. Also, dont take those stangs lightly, they can be made insanely fast...
