I just don't get it, we lined up on the highway going around 60 he gunned it before I did, I stayed at his side mirror until we hit about 90 and then I started to pull on him. He let off around 110 but by then the front of his car was at my side view.
Shouldn't he have taken me easy? I am no fan of rustangs but seems to me he should have had me.

Yes, technically he should have. They will trap much higher in the 1/4 than your car. Could have been driver error, poor running car, badged 6, who knows. Anything can happen on the street.
So lets not have a bashing thread how someones friends brothers uncle has a stock GT that ran 12's. Or how the mustang should have lost because someone beat one in their Grand Am.

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
Yes, I am sure my car is stock 
The only reason I know it was a 01 and that it wasn't a badged 6 was because after the race he rolled down his window(which was tinted heavy black) and it was one of my friends brother. I had to call my buddy to ask the specs on it.
I was I had two passengers other than myself btw.
What are the gear ratios is there any way I just had him in the top end?

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
i dont think, even with crappy gears, he should have you outpowered by a good bit...and those cars arent heavy. if anything, his topend should have pulled on you and you should have him down on the low end from a dig

I still don't really understand it, the only thing is that there are so many factors that can play a part in a race like that; from weight to engine/tranny problems to rear ends. Who knows...

I tried to run my buddies 1989 Mustang GT...yeah I got pwn3d by 1.5 Car lengths. We were even at the start but for some reason that 5.0 HO seems to wake up at higher RPM's...either that or the 5speed his is sporting was definately working to his advantage.

I ran my mine against a friends modified 96 gt going at about 60 and he just straigh up pulled, I didnt gas it all the way and he started a bit before me, but he still would have took me, im not sure about 98's but i know 98's where some of the slower models

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
If you're losing to 96 - 97 Mustangs by that much your car needs some help. Even the 98 Mustangs with the better heads (not PI yet but better than the 96 and 7 heads) with 3.73's, CAI, full exhaust with X pipe, and PI intake could barely break into the mid 14's. Be it traction limited it still wasn't very impressive for the ammount of mods it had. We shot this car with a 125hp dry shot of spray through the MAF however and it would click off 13.5's with the same traction issues. God I wish he still had that car, the nitrous was hid very well and people knew those 96 through 98 cars sucked. Not many people realized that the 98 had better heads and that the PI intake swap woke them up immensly. To put this in perspective a local kid has a 1985 IROC z with the TPI 305 in it. We've done a few free mods and just tuned the car up and he could've put a serious spanking on that Mustang. The TPI cars have to be cared for properly to hold their own and the same goes for the Mustangs. It sounds to me like you just caught this kid on the right time and the right day. If he tuned that car up and threw a few mods at it you would probably be in some trouble, but that's not how it happened and the win belongs to you. If the kid's an intelligent sportsman he'll make his car faster and come back for the rematch, you should be working to match his bet with some mods of your own. In any event congrats on the win and have fun with any future races.

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
Gutted air box, porting, 3in exhaust. The first 2 mods are basically free minus the grinding bits and the gaskets you'll need to replace. You can also bump your timing up and do small stuff like wire the fans to run on a switch. The free mods take these cars quite a ways. After that I would consider headers and a good Y pipe to go with the 3in exhaust. The exhaust will cost you some coin but be worth every penny. The ultimate college student mod, the one that kept me winning all through college is a nitrous kit but that depends if you want to get serious about racing or just make your car a bit faster.

They did a few weird things to the 94 and 5 Mustangs, most importantly they stuck the Thunderbird intake on it. They also had a TINY MAF and the TB is more restricted than the earlier ones I've seen.

I'm still convinced my 84 el Camino was faster to 80 then my camaro! Then again the elky was straight motor and i rebuilt the rear end with a 3.42. which was cool until i was going 65 at 3,000 rpm. wish i had a 700r4 back then . lol.

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
There are several lightly modded guys over on corral knockin down mid-low 14s in the 96-98 stick cars. Lightly modded as in radials, shifter, gears, exhaust, cold air type of stuff nothing major.
But if you were at just the right speed that his trans wouldn't downshift to 2nd gear, that would explain it. The 4.6s are not known for their low-end, and the Auto cars are significantly slower than their stick counterparts...
As for the 94 being slower than the 93, yeah it gained a hundred or so pounds and got a crappy intake. the 99+ cars are a bit heavier as well. I think curb weight for your average 01GT auto hardtop will be around 3400ish...

They had larger MAFs in the 94-95 cars, which make the same power if not slightly more than a fox.

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
If they hard larger MAF's then the 80's and early 90's mafs must've been tiny. I've pulled 2 MAF computers and sensors from the junkyard and the passage in them is very small. Is it possible these aren't stock MAFs or did the earlier cars have even smaller ones? If the 94 and 5 cars make more power than the earlier cars does this mean the Tbird style intake isn't bad? I do very little Ford stuff, mostly for other people but I get asked about this quite often.

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
The more power is so slight it really isn't much if anything to write home about. The MAFs on the fox bodies were slightly smaller and an SN95 MAF is an upgrade some people do. Yes both are small in size though, and aftermarket stuff is much better.
Re: stock 87 iroc 305 vs 01 stang gt...and I won???
Well, you ask what kind of mods, your a colledge student. Well, if you are a colledge student, NONE. Wait a couple of years and after you get out of colledge and get a hell of a job, build yourself a real racer. Sorry guys, but some things are more important then having the fastest car, especially if you are in colledge.

I've raced a few with my car it has a 305 with an edelbrock carb and some bolt ons and I've beaten any that are stock and some that have had some bolt ons ,for some reason those cars don't seem very consistent but that's like our cars I've seen some TPI 350 cars that just don't go for one reason or another and some 305 TBI cars that are actually pretty quick.

Re: stock 87 iroc 305 vs 01 stang gt...and I won???
Yeah, it seems around here that the F-Bodies are the inconsistent ones. Everyone that has a Mustang save for a very very few seems to have pretty consistent power for what they are, on the other hand there is a 94 Z28 vert that spanks *** and beats all kinds of cars it shouldn't, and theres a 97 Z28 M6 T-Top car that gets eaten alive by stock 5.0s.... I saw a very mildly modded 94 GT take this car one night. It has nothing obvious wrong with it, less than 100K... And it's been driven by several different people in races so its probably not just driver error.

Thats why I said college budget, I do have cash set aside for frivolous things. It is all about keeping it balanced; I don't do movies or go out to eat very often, my friends and I usually stay on campus. Let me have my fun

from what i understand, the fox mustangs were light, but from 94' and up, they got pretty portly. isnt that why the 94's were much slower than the 93's even though the motor was exactly the same?
