A kid at my school has just bought 89 mustang. All stock expect for exhuast and 4.10 gears. Its a 5spd. I think I can take him in a quarter because he tops out at 85 mph with those huge gears.
anyway, he will be reading these responses so be very helpful with your comments please. Thanks.

brodyscamaro

need specifics on your heads, but im guessing you got him beat

406TA

You list an '89 Mustang GT as one of your kills. Have you raced him before or is this a different car?

Ian_F

He shouldn't top out at 85, he should be able to run to at least 100. Oh well, sucks for him. Yeah, I don't see why you shouldn't be able to upset the little ford boy a bit. Go for it.

25THRSS

yeah, he shouldn't top out at 85. It should be much higher than that, especially in 5th gear. I say you will win. Those gears are probably actually hurting him more than helping.

Nic

He should have a legit high 13 second car if he can drive at all. Those gears are perfect for him, should have him going through the traps right past peak hp. Also, depending on how tall of a tire he's running, he should be topping out in the neighborhood of 115 mph in 4th gear. Where'd you get that he tops out at 85?

MdFormula350

i say you should win also. good luck.

Stangaholic

Nic, you seriously think he is going to run a high 13 with just gears and flowmasters? Come on now man! I have a 92' 5.0 and with Flows and a new king cobra clutch I ran 14.92. I dont see how 4.10s are gonna knock off a whole second especially since he probably cant drive his new car, and he will probably spin more from the 4.10s and it doesnt mention him having drag radials.

BadBowtie88

I'd say he's yours. Friend of mine had an '88 with 4.10's and went 15.3... He couldn't drive it worth a crap, but, Stangaholic went 14.92. Who knows.

Nic

14.92? I went 14.70's with an aod 'vert with just exhaust and 3.73's. Either your car is way out of tune or you can't drive. The only reason he shouldn't be in the high 13's/low 14's is if he can't drive. Hell, my dad's went 14.70's in his bone stock aod hatchback.

I didn't say he'd win, but like I did say "he has a legit 13 second car if he can drive at all."

Black363IROCZ

nope, he'll smoke you, unless it's like a 4 cylinder or something. Look I dislike stanks as much as the next f-body guy, BUT, the 87 IROC 350 wasn't as powerful as the 89- models, and the stang is much lighter. 4.10s will help alot, a stang isn't limited like a TPI, it will pull to 6200 rpm easily. he won't top out at 85 MPH, lol,where'd you get that from? He could pull low 14s on you with that setup, you'll be running a 14.9 at best with the 87. do some free mods, get an HSR or mini-ram and run him again, it'll be a better race, you'd probably take him if not beat him with that then. they make less power, but they weigh less, why do you think a civic is even capable of 17s lol, cause it weighs like 2400 lbs.

25THRSS

I think you need to read what mods he has. He's got the stang I think. If all he has is gears and catback exhaust then there is no way in hell the stang will run 13's. He says he beat a 2001 GT, and if that is true then he's got the stang in my book seeing as the 2001 GT prolly runs low 14's.

Well given the mods in your sig, I would think you would be able to run at least high 13's with good traction and driving. I think you can take the 'Stang but the potential to be a good race is there.

5.0mustang

As far as high 13s for the Mustang, with 3.55s, cat-back, and pulleys I have seen a 1991 Mustang run 13.6 with tires. On street tires it was a high 13 second car, so Nic is right there!

As far as hitting only 85 that is a joke because in 4th if he runs right near the rev limiter he could hit a little over 110.

As far as pulling till 6200, I dont think so. On the dyno my car peaked at a little under 5000 and we shut down well before 6200 and the power was pathetic.

Nic

Yea, you're going to start floating valves at about 5700 - 5800. Most guys I know running good times in their stock/near stock 5.0's are shifting at 5500.

Black363IROCZ

not if you have proper valve spring pressure. All my buddies wth 5.0s run it straight to 6 grand before shifting, stock or not.

Nic

Hope they're still running stock valve springs

Black363IROCZ

I wish I knew more about their car *NOT a ford guy* lol. They say that timing issues or some other blah blah **** kept them from shifting at 4500 rpm and they ran high 14s, then they "fixed" it, started running mid to low 14s and revving to 6200 and shifting? I always thought the 5.0 made peak power at the same rpm the TPI motors did, and they don't have crappy intakes that restrict airflow past 4500 rpm . I'm guessing by fixed he meant advanced timing lol but I'd think he'd just be spinning the motor, but it pulls past 5800 rpm hard when I was in it.

25THRSS

I think i'm gonna take the word of a 5.0 owner on this one. Pulling to 5800, right.

Nic

They make peak power right around 4800 stock. My friend that runs 14.0's with just a K&N and drag radials is shifting at 5500...he's also a hell of a driver.

5.0mustang

I shift at about 5200-5300, and my car makes peak power a little under 5000. If they are ruuning up to 6200 they are killing their times. Tell them to shift near 5400-5500 and they will be 13s!

Black363IROCZ

hmm, perhaps he had an aftermarket cam and didn't know about it. he was shifting at 6200 every since he got it cept for that timing issue lol. I dunno, I've heard 5.0 factory freaks exist. it's a vert, they are much heavier than the coupes.

5.0mustang

I dont think there are too many freaks, just cars that have been taken care of better. My car has 130,000 miles on it which is why it runs bad times, and my dads has 70,000 miles on it and runs killer times. His was always garaged and never seen rain, and mine was daily driven and kept outside for nearly all its life. Either way you aint making power to 6200 no matter what.

BORLAZ06

i really doubt he'll top out at 85.

assuming both cars run good. id say he gots you. but you never know. jus go out there and run him and drive it like you stole it...haha.

Black363IROCZ

oh yeah, I agree totally, it's just some of the stankers (that's what I call 'em ) round here seem to say they need to shift at 6200 rpm for some reason , I shift my engine at 7000, but it's a solid roller and I'm making peak at 6500 rpm, 7100 is where I set my rev limiter. I guess they're just taking full advantage of the forged internals

super83Z

back on topic, I definatly think you got that mustang beat.

BadBowtie88

Agreed.

f-crazy

id lay my $$ on the roc

87irocz350

Yo, guys I'm sorry I havent responded. Buy ya know, I'm busy alot know that Ive moved from michigan to Kentucky.
Any way, the kid with the car told me he tops out at 85MPH. That not coming from me.
I think it should be a good race. He can smoke those mothers through 3rd easily. That will be his demise

5.0mustang

A Stang with gears can roast the tires pretty good but it can also be regulated to your advantage. A good driver makes a world of difference.

I would say drivers race, and 85 mph is a joke.

Nic

lmao...I just figured it out...that kid is a frickin dumbass...his speedometer only goes up to 85. Please shoot him and remove him from the gene pool immediately.

BORLAZ06

85...BUAHAHAAHAHAAAAAAAA!!!

5.0mustang

OMG Nic your right. I never even realized that till you said it.

I guess he has never gone past 85 because when you do the needle just keeps going. I have seen them almost straight down before. This kid isnt too bright if he thinks the speedometer is what holds the car back.

I change my mind, the Iroc wins this one because of the driver!

5.0mustang

Wait one second, if he does have an 89 he has a 140mph speedo. It was 87-88 that had 85 mph speedos. Maybe he really has an 88? Does he have mass air or speed density?

Black363IROCZ

hey man, a Grand Nationals speedo only goes to 85 mph lol.

BORLAZ06

i was referring to that kid who said he tops out at 85....which aint true even with 4:10s. i just laughed bout it.

Black363IROCZ

ohhhh d'oh, my bad lol!

12sMustang

My 1989 mustang got its best times when shifted right at 6000 rpm........on the stock tach. That is what I think the problem is, here.
