86IROC350NY

Hey,
What would you need to mod a 5 speed 86 iroc with in order to be able to beat a Mustang Cobra? There's a guy at my college who has one and all he does is rev his engine all around campus. I just got an 86 IROC and the guy i bought it from said he only lost one race (and that the car was his money maker...needed to sell since he had a daily and needed cash for school). I want to know what i can do to my car to be able to take him. I am running with Dunlops, the tread is really good, but I am thinking of getting the new eagle "NASCAR" from goodyear...or the Eagle HP tires. Tell me what will hook well for a 5 speed with low gears.

Depends on what year the Cobra is. If it's a fox body Cobra, it probably runs low 14's to high 13's. If it's a 94-98 Cobra, it probably runs low 14's at best. If it's a 99+, then it could possbly run high to mid 13's, and is a pretty quick car. Either way, youre gonna need some extensive mods to keep up.

EDIT: Okay I didnt even look at your sig. I was assuming you had a 305 TPI. I'd say a good cam and intake could possibly get you into the low 14's. Heads would really bring your car to life, I hear the iron Vortec heads are really good--especially for the price($450-ish) but you need to buy a Vortec intake to match the heads... I think they run about $200-250 bucks, not sure, but if you got the heads and intake, you could in all likelyhood wax him, if he's stock that is... you gotta watch out for those damned fox bodies, if that's what it is.

Maybe a 95, but it looks kinda like a 5.0 with COBRA written on the back bumper instead of MUSTANG. I was thinking of a sneaky pete NOS system for a little kick, albeit a small kick, but an extra 3MPH and .2 off the quarter may be worth it...for now.

! can't wait till i win the lottery. All i want is that 383 Pro Street from beck Racing engines, along with a new tranny and an auburn posi rear...yeah a blower would be good too.
A good 13 grand right there...and a long time without a car.

I saw a receipt in the console for 600 dollars to rebuild the heads. looks like some porting or something, I can't make out the writing. i also think he owed money from a last mod because the work done to the heads was only 250.00 and the bill came to 600.00.
I was thinking of getting vortecs but i just want to see what i got before i get new heads.

Its probably 1 of the slower 1's. You've never ran your car??

86IROC350NY

I just bought it a month ago. and until last week I drove it about 3 times since it wasn't at my school yet. His cobra doesn't sound that mean...mine is more "throaty" but that may be his stock sound over my modded sound.

Mark A Shields

Your sig, says rebuilt 350, what kind of cam/heads do you have. What rear gears do you have as well?

86IROC350NY

I haven't had the time. I am going to bring my friend to check out the car this week. I Don't know the cam or head specs. That's what I really need to find out. i think he said there was a hotcam in the engine. It wasn't a rebuilt 350, it is a "new" engine (15,000 mi)..I made a mistake.

If you have that cam, you should know. You'll have a really lopey idle, and it will be loud on acceleration.

86IROC350NY

The idle is lopey. The car is VERY loud on acceleration, but that can be because of the exhaust system. I can hear a lot coming from the engine though.

Mustang5L5

If he's having head work done then it can't be one of the 4.6L DOHC Cobras, it haas to be a 94-95 5.0L Cobra. They say MUSTANG on the rear bumper and have the horizontal taillights and the regular GT hood. They come with 240HP stock, but like any 5.0 they can be built up pretty easily and cheaply. They come with GT-40 heads and a Cobra Intake manifold stock, but they could be improved. A Cam and some headwork and the other easy mods could put that car around 300HP easy. I've seen 5.0 Cobras run high 13's with good drivers but low to mid 14's is the norm stock. But the car is just as easy to make fast as any Fox body 5.0.

And also, the 96-98 DOHC 4.6L Cobras can run 13's. My buddy went 13.8 in his stock 97 Cobra. Those DOHC motors love high gears. They come with 3.27's but they should have come with at least 4.10's. I've seen .5 come off with just gears on those cars

Does the hood look like this:



or this:



You stand a better chance if it looks like the one on the bottom.

There are many stock 99+ GTs running in the 13s at www.corral.net

Cobras can do somewhat better than that stock. And with only gears, they wake right up.

Mustang5L5

No, but my rims do! (Shameless plug for my latest mod)



Does that add HP?

Nic

I love the way your car looks. I say we put my drivetrain into your body and share

Mustang5L5

I'm all for that!

5.0mustang

Looks good Mustang5L5, I've only seen one other car with those rims parked at our local golf course, and I immediately thought they were unique and really nice looking.

Especially with your black!!!

Monkie

The fox body cobra is slow. The 94-95 can be fast I guess. And the 96-98 are fast. And the 99+ is faster. I am running low 13s to high 12s with just a couple bolt ons. Good luck man I dont really know how fast the IROC are.

12sMustang

FWIW, I drove 86IROC350NY's car today. How "lopey" would this hotcam be? If he has any cam, it has to be a very mild one. The idle seems pretty smooth to me, and there is no problem with bucking while cruising at low speed, like there was with 2 seperate cams I had in the 5.0, though his tach doesn't work quite right and is reading rpm much higher than they actually are (sending unit?). I told Dan, that I'm pretty sure there is no cam, but that is based on my limited experience with aftermarket cams. I'd appreciate any info pertaining to how streetable a "hotcam" is. Driveability seems stock to me.

Thanks,

Chris

Nic

How is the '93 slow but the 94-95's can be fast when they have the exact same motor and the 93 is lighter? Also, do you have any timeslips showing you run high 12's/low 13's?

vortecfcar

Dont ask for anything from monkie.......He beat a C4 from a roll and Im sure he walks LS1s all the time. Once he gets 8.5mm plug wires he'll be in the 11s for sure

mean 5.7

:lala: :lala: yeah wires are everthing

12sMustang

Does anyone have any insight in the question I asked about hotcams?

Thanks,

Chris

vortecfcar

the hotcam is a pretty aggresive roller cam that would have a noticeable change in idle, will pull strong up to 6200 RPM at least and is not generally put in factory replacement engines just for the hell of it.

the guy who sold the car to you probably just meant that it had a hotter cam.....not the "HOTCAM". Thats my analysis of the situation at least.

12sMustang

Yeah, if the "hotcam" is a hell of a cam, then it's definitely not what the car has. The car has a nice exhaust sound, but no noticable lope to it. Thanks,

Chris

Monkie

You fu(king smart *** I don't even have plug wires. BUT I will tell you what...how about I buy a set just for ***** and giggles and I can give them to you to shove up your a$$? Sounds good to me. :lala:

914Mula

If you don't have plug wires how does your engime work?

Nic

They have 8 seperate coil packs.

Monkie, I'm still waiting for timeslips.

Monkie

Then you're gonna have to wait until this weekend.

1991tealRSt-topGuy

this isnt the same monkie that claimed his V6 camaro could run 15's and then took it to the track and ran a 17.4

is it?

Monkie

lol ummmmm no. I knew my old RS couldn't run 15s. The only time I ever took it to the track was a 1/8th and I ran a 10.2 if memory is correct.

vortecfcar

no way in hell a V6 ran 10.2, that equates to about a 15.7 in the quarter. I suppose your cobra can run 7s in the 8th mile then huh. I want a video of your car running 12s or a timeslip and some verification that the slip came from your car to actually believe it.

Its a never ending battle on this board to fight the BS.

z28onTweenkies

mustang 5LS, how did you go from four lugs to five? a buddy of mine has the cobra wheels in those pics and he will sell them to me for 100 bucks in great shape. my other friend has an 86 5.0 and he just rear ended someone and does not know what he is going to do with the car. this is giving me ideas, id love to own a fox body to go along with my z.

1991tealRSt-topGuy

oh really?

EVERYONE LOOK AT THIS:

OOps, Monkie was proven wrong! Now he will try and say it was a dofferent Monkie with an SVT under his name!!

"Low 13's/high 12's"

I'll go along with Nic here...SHOW ME THE SLIP. Did you go to the track this weekend...cuz its monday and were waiting to see.

Did you ever read the story about the boy who cried wolf?

I've always wondered why people lie to car enthusiasts. They can always discren the truth.

tpivette89

Greenville SC, where the 99' Cobras run 12s, and the BS flows like wine

Monkie

So I am throwing BS now? Teal do you care to show me or anyone else here where I claimed my V6 could run a 15? Looks to me like Im not the one but you are. I never said I could run 15s. And why would I give a **** if I could get someone that lives in Delaware or Jersey to believe me over the net? To me you guys are a screen name. So get over it, if I can run a 11 or a 19 in a Cobra...how does it matter? Teal you have never been one to do much of anything on this board so try not to start BS wars.

1991tealRSt-topGuy

thanx to vortecfcar's equation you just did claim to have run a 15

you also claimed to have beaten 305's


look i'm not trying to **** YOU off

i'm trying to let everyone else here know about your horrible exageration

it seems you have a bad habit of it

Camaro_hunter_d

LOL GOOD ONE:sillylol: :sillylol: :sillylol: :sillylol: :sillylol: :sillylol: :sillylol: There still has to be a wire to connect the coil pack to the spark plug!

Monkie

First off my engime doesn't work. Second off show me a set of replacement plug wires.

cort351w

My ***, some of you need to learn about the newer cars! Monkie's car, as well as all 99+ 4.6L motors (2v and 4v) do not use plug wires. They use a coil-on-plug ignition--the spark goes directly from the coil to the plug. Very efficient. The LS1's and Gen III truck motors use a coil-near-plug design. They use plug wires, but they are only about 6" long. Both the Ford and GM designs use 8 seperate coils.

89camaroRSV6

so what can a 99 cobra run stock in the 1/4 and with his mods what should he run??

Monkie

a bone stock 99 Cobra with good traction and the "fix" should run a mid 13. With the mods I have (especially the 4.10s) I should be close to a low 13 or a high 12. AND I could give a **** less what some guys on a message board think I should and shouldn't run.

89camaroRSV6

wuts teh "fix"

vortecfcar

a large shot of nitrous and 300cc's of "run your mouth"


Monkie, time and time again you've called out and been called out...seriously, when are you gonna learn to stop the controversial posts.


I think Ill drive to SC and shake your hand on the first post I read of yours that comes close to believable.

Dont get technical and try to turn this whole thing around over a set of plug wires- everyone knew what was meant by that post

Monkie

Yes....as I said I can run a low 13 to high 12. How is that not believable?

914Mula

No need to get defensive but, I do appreciate you answering my question.
