93 Z28 v.s 99 Cobra

My buddy just got a 99 Cobra, 5 speed, We went on the highway last night went from a roll at 55. We where all over the road it was pretty wet still from rain. He started to pull on me a little but not as nearly as much as I thought he would....I just need to get my LS1 already so he shuts up about thinking he can beat me. We need to run it at the track, when it is dry....

Hmmm, shoulda beat him, the 99s are notorious for being slow.

Actually there was a recall on those cars to fix em. Most owners returned their cars to get the claimed 320hp.

If it was a fixed car it should have beat you. Good run none the less.

Those 99's after the fix running pretty hard, yea id imagine he'd pull you fairly easy high end. Yeap the LS1 should even things up...good runs

So we raced again today since it was not wet. The first run was at 50 to about 110 I had him by about a car and a half. The next one he got the jump on me and had me about 2 cars. Then the last one he took me again.

Just gives me more push to getting a M6 LS1...Then ill show him ;)

they were close races for the most part. we probably shouldnt have raced when it was wet out cause he spun bad, but i left my traction control on for that reason, and i left it in 3rd i was afraid to go to 2, cause i coulda lost it. the 3 races we had today were good races except we ran out of room on the highway, stupid traffic. then this mercedes caught back up to us after the first run and he kept riding our bumpers then we raced again and left him in the dust. guess it couldnt keep up.
oh well, it was fun.

Ive seen a properly driven new edge cobra pull a auto LS1 ss pretty hard from a roll. Id imagine it wouldnt have much problem w/ a auto Lt1 w/ cai and light exhaust work.

Yea it should be faster than your auto. LT1. Plus you have 113K W/only a CAI. But think about it like this. His car is 6 years newer and your hangin close behind him. Not bad!

Or you can be smart, save ass loads of money and just toss on a set of headers.

WOW so you guys raced in the rain, while in traffic? Not smart guys. Next time save it for 2am on a dry road, street racing gets it bad rap from people doin stupid things like racing a on wet road in traffic.

You guys should both feel lucky that you guys didnt kill anybody.

No rain....Just a little "damp"....It was at 11pm no traffic....

The second time we raced it was dry and there was traffic.

the new generation mustang cobra or the 99-04 generation? if its not the newer generation cobra then i call that out. it would not walk a ss from a roll if they were both stock

He said New Edge Cobra, which means it's a 99 or 01 Cobra. A stock automatic 2.73 geared LS1 can be pretty pitiful from a roll - so bad in fact that a N/A Cobra could walk it.

Only if you find the 273 geared car at the wrond mph. Those gears shine up top, especially from a 70+ mph roll on :D

It was a 323 ss car and i was in the ss so call out whatever you want. 40 mph roll the new edge put 2 cars instantly on the ss and it stayed that way til shut down...autos arent good from roll. Then then went from a dig and it was neck and neck...both cars being stock. I personally made one pass in the SS first time driving the car ever and ran a 13.6 @ Englishtown. This was on a scorching summer day. The SS was easily capable of a 13.2-4 on a cool day. That just shows you how strong the new edge's run in the right hands.

I said an ss, ss's dont come w/ 273's

Where did you hear that? I have a 1998 Camaro brochure, and it makes no mention of the G92 performance axle ratio being a necessary selection for the SS package. The SS package description also makes no mention of either 2.73 or 3.23 gearing.

Nice kill, but racing from a roll is dumb.

That just shows you how strong the new edge's run in the right hands. 2.73 and 3.23 is not that large of a jump, 40mph is still a terrable place. When I had my gears in if I floored it at 35-40 it would downshift to like 2300rpms or something and barely move.

Not sure what brochure that is but the SS only comes in 323's for autos

I hope whatever GM worker that printed that up no longer works there.

What happened to racing from a dig? 50+ mph starts? WTF? :eek::eek:

WTF indeed...:confused:...

We where gonna but it was kinda wet/damp out so we wouldn't of hooked up like at all! So we where gonna wait til it was dry out and race from a dig but I ended up selling my car.

:rolleyes:why is racing from a roll dumb?......... some cars are faster 50 mph to 100+ while others are better at 1/4 mile. i like to do both if you really want to prove ur faster.

For instance my friend had a Civic hatch with a H22a swap, from a dig he always lost to f-body's and cobra's, but on the highway from a 50 mph roll ive seen him rape Camaro's,350z's and Stangs all the time

unless all u guys care about is 1/4 mile......................

if youre testing the cars setup then dig races are fine... but if you want to test whose car is sheerly more powerful a roll race where traction is not a factor is the way to do it

Ive seen a properly driven new edge cobra pull a auto LS1 ss pretty hard from a roll. Id imagine it wouldnt have much problem w/ a auto Lt1 w/ cai and light exhaust work.

You're sure it wasn't an '03 or '04 supercharged model?

But then again this requires both cars to be in their power bands. Many times the roll will put one car at an advantage that may not be able to be offset by sheer power alone.

Traction is as much a part of racing as hp and tq.

I live my life a 1/4 mile at a time. :D

oh no i understand this, gearing isnt the same for everyone... but usually approaching speeds of 120+ you kinda figure out who has the faster car because one car will usually start to pull.. even if the other car gets the jump off the start, if youre car is truly faster then you will stop their pull and begin to pull on them, now if they let off before you pass them you still know whos car would really win but obviously this is a topend competition...

around here we usually just go til you realize youre not gonna pull him or you pulled the **** out of him

i usually start roll races' if i do them from about 15mph... Roll race's for a A4 are asking for a ass whippin'.. esp if you have the right converter in it.. they just don't go nowhere up top.. . although i do run some other folk's from about 50mph to 180 or so.. but that usually end's up bad for them. unless they have about 750rwhp.. :D then it's close...

You're sure it wasn't an '03 or '04 supercharged model?

Seeing that it was in 2001 yea im sure...

Or you can be smart, save ass loads of money and just toss on a set of headers.

Yeah....Headers will give you the win :eek::eek:

Not sure that will help him much...If the Cobra can drive (launch properly) then it would be a no contest every hit against a lightly modded LT1.

Later

Ummmm, no..... Long tube headers on an LT1 is probably one of the single most significant mods you can do. The factory exhaust on an LT1 is garbage. It isn't uncommon for LT1's to pick up 25-30 RWHP with a good set of long tubes and catback.

Those 99's after the fix running pretty hard, yea id imagine he'd pull you fairly easy high end. Yeap the LS1 should even things up...good runs

Even things up? LS1=far superior.

Unless its a terminator Cobra.

Are we talking about a manual Cobra vs a auto SS from a roll? 9 times out of 10 this wont happen. Manual vs manual there is no way.Especially when you say pull hard. Once the LS1 wound out it would reel in the cobra with the quickness.

Seeing that it was in 2001 yea im sure...

:lol: You failed to mention that. :)

It is common knowledge that the "fixed" 99s and 01 Cobras are mid to low 13 second cars. They are limited in the 1/4 only by it being very difficult to launch with a IRS. Yes they can fight a LS1 all day. 4v heads flow well and the cars like the ls1 scream up top.

I wouldn't say it's common knowledge.... I have yet to see it on any kind of regular basis. Most of the '99 and '01 Cobra people that I know that are running low 13's are running 4.30 or 4.56 gears and a host of supporting mods. To say they are all mid to low 13 second cars stock is misleading.

2v GTs with mods and gears are low 13 second cars. With 2 more valves per cylinder, better flowing heads and a starting point of 60 more hp I would think they could hit mid to low 13s.

I am not saying most cars are running 13.1 and 13.2. I am saying that it is not the norm for them to run high 13s to low 14s as that is stock 5speed GT territory.

I have seen plenty run decent times and have seen many more timeslips over on modular depot and the corral.

If I remember correctly the best stock time ive seen posted for a 01 was 13.2@106 over on the corral and thats mechanical identical to a fix'd 99. 4.30/4.56 plus some light exhaust work should be good for higher 12's w/ traction...It doesnt take much more (if anything else at all) other then gears and traction to hit 12's in a 4V.

Dont be a smart ass. Keep the fighting words to your self. Your alwas trying to piss someone off with a dickiheaded comment.

There was no need for this comment except you felt like being an ass as always. There was no indication that I did not comprehend the topic. the question was a way of expressing doubt.

So you where the one who miscomprehended acting as if the qestion was written in a literal since.

Propaganda. Hp vs weight you would need nearly 340 HP for these kind of numbers. Does a nearly stock 4 v put down 340 HP?

I guess so because thats what kind of numbers they turn.

I guess so because thats what kind of numbers they turn.

And yet, the answer is NO. A stock, naturally aspirated 4V 4.6 doesn't make anywhere near 340rwhp.

No No, your right. The mustang is magic. It weighs nearly the same an an LS1 car and makes 75+ less HP and what may be an even bigger torque gap but can run nearly identical times. Give me a ****ing break.

No it sure dont but it as fairy dust in the gas tank. The Mustang is not held bye the same laws of physics that applys to that of an LS1/lt1 car.

As much as I like mustangs its unrealistic comments like these that piss me off. Its just like us saying " Oh, the LS1 runs nearly the same as a SC 03 Cobra" There is a bigger gap between a Gt and an LS car then there is an LS1 car and a SC cobra.

I hate comments that lack logic.

I once street-raced a guy with a KB-supercharged 99-04 GT in my lid+catback '02 Z28. I had a 250+lb passenger in the car with me; he was alone.

I won. :D

Sure.... All the drivers i've seen and know have no idea what they are doing. All of the good Cobra drivers must all live where you're from. :nuts:

Whatever man....:no:
