86 GT 5.0 vs 87 IROC 5.0

In a short dash and a burn out contest The IROC should win right......well My car is lowered with out the relocation brackets, has a Cat-back TPI 5 speed(3.45 gears), and bla bla bla the engine that is in is a 8 mile 1990 truck 305.....The Gt has 160,000 miles on it....and sound like a cat-back.....He claims he can't use 5th gear because it is too high and puts him 100+ mph....hummmmm.....guess he has crappy gears.....
ahhh **** it....I know the answer..!! The F-bodies handel better then the stangs right?

Compared to an f-body the mustang handles like a garbage can on wheels. If you look up skippad numbers even the Buick Grand Nationals will out corner a mustang and the mustang you would think would be the sportier of the two.

Explain a "short dash". Straight line 0-60? It's all going to depend on the driver. If I remember right, the '86 5.0 was rated at 200 hp. The '90 305 TPI was rated at 210 hp (in the Camaro, I don't know whether the truck version was stronger or weaker). If a short dash is a straight line race, who cares how the Mustang handles? Typically, they are easier to launch than a Camaro, and therefore will have a slight edge coming off the line, which will be difficult to make up in a short dash.

Also, a burnout contest? Please. What on Earth will that prove other than the fact that you guys enjoy buying tires and clutches?

I raced my friend's 87 Gt stang 5 spd in my other friends 5.0 5 spd 91 Z and my buddy in the mustang spun for 4 seconds off the line before he took off on the other hand i launched the camaro with a slight chirp of the tires and the kid in the mustang is a MUCH better stick driver than I am. Any mustang I've ever tried to launch would usually spin for a little while before it got going unless it had stickies on the back.

I'd have to say that if he spun for 4 seconds off the line, he didn't know how to drive that car. Typically what I have seen when comparing dyno numbers and timeslips is that an F-body will take about 20-30 more hp to run an identical time as a Stang. The Stang will get a little advantage at the launch, and the F-body will have a little higher mph at the top end of the track. This leads me to the conclusion that the Stangs are a little easier to launch.

By the way, I cut 2.0 60's on street tires and a completely stock suspension (with over 120,000 miles on the original springs/struts/shocks) on my first night at the track (and my first time ever trying to launch hard) in my 89 GT. At the time, my car dyno'd 242/305. I've since been to the track one more time (after some additional mods) and cut 1.9 60's, dynoing 283/306. This was also after some suspension mods that were more auto-x oriented than dragrace oriented. Also on street tires. I recently bought some ET Streets, and hope to get my 60's down to the 1.7-1.8 level.

For comparison, my Mustang ran 13.7 at 101, compared to your 13.8 at 104, and now I'm running 13.2 at 104.5. Have you had your car dyno'd?

I'm not doubting what you're saying just in my personal experiences It seemed to me like the 5 spd stang was a little harder to launch. But then again that's why I own an automatic alot easier to launch and alot more accurate. But if you can drive a 5 speed for the most part it will always be quicker.

That day I only got one run in and it was rather bad as the times show. I've never had the car dynoed but I'm guessing if I went to the track again I should hit low 13's with little trouble at all. I'll probably never know since i've got a new setup almost done anyways which should put me in the low 12's or better.

I'll be shooting for low 12's, maybe 11's, next year as well. I'll be doing a 347 stroker, looking for close to 400 rwhp, and may add a 75-100 shot of nitrous, just in case I run into any cocky Viper owners...

My intake manifold is already set up for it. The system is completely internal, with the hook-ups for nitrous and fuel at the back of the intake near the firewall. Almost impossible to see, unless you know where to look and what to look for.

What a bunch of Crock!!

Yeah or the fact that it weighs between 200-400 pounds less!

The point is, the F-body needs the extra hp to overcome the weight disadvantage. Running equal times in the quarter mile, Stang vs. F-body, typically the Stang got a better 60, and the F-body plays catchup. Weight is just one of the factors in getting the car into motion.

Once you get into the 13 second range not many of the ricers are worth your waste of gas. My favorite target still remains punkass kids in 5.0 Mustangs with nothing but exhaust that think they've got the fastest thing on the road. I love the wide-eyed look of disbelief on their face when their invincible 5.0 with slowmasters goes down to a stock sounding coupe.

Sounds like my approach on street racing. Showing up the punks in their cars that have bone stock motors and a catback exhaust and think they're invincible. My friend is a little cocky about his car and I'd like to show him up when springtime rolls around just to teach him a lesson. He had a 87 5.0 5 spd and thought it was the best thing in the world(slowmaster exhaust and h-pipes). He then sold that and bought his cousins 87 GT mustang which last time we went to the track ran a 12.0@116 . Even though he has a fast car now he still has that ignorant attitude about cars "the mustang is always faster and better than any chevy out there". He knows little about cars at all except where the go pedal and the clutch are. The look on his face will be priceless and I'll be sure to have a camera..hehe.

Dude, did you read the posts? I'm doing a stroker motor targeting 400 rwhp with a 100 shot of nitrous. I could deal with ricers when I was stock. Now I'm hunting for big game. Here Viper Viper Viper.... SSHHHHHH, I'm hunting ZO6's....

lol.....I just think it would be funny as hell to see a race in which there was a 16 sec ***** vs a 12-11 second domestic sports car. It would be just like it was sitting there......LOL

I had a shot at a VTEC Integra at HRP a while back. We were in the staging lanes, and I was talking to him because at the time I didn't know much about them. I asked how he was running and he said he was really disappointed because he had installed a header (still can't get used to using that word in the singular) and his times had slowed from a 15.7's to 15.8's. He asked what mine ran, and I told him I'd just run a 13.2. As we got closer to the starting gates, about 4 cars back, he apparently realized that he'd be running against me which would result in a loss by 20+ car lengths, and he pulled out of line... I wound up losing to a 3rd gen. I ran a 13.4, spinning too much off the line. The 3rd gen ran 13.5, but had a much better r/t...

haha that's great..My one run at the track was against some kid in a turbo SAAB and he ran a 16.1 compared to my spinning 13.8. It did look like he was standing still. It was truely a great thing.
