New LS1 Owners - Newbie Tech - Any one raced An 03'-04' Cobra?

:secret: Anyone raced a 03'-04' Cobra on the street yet. Well I got my first chance last night after this guy did a fly by on me. I was driving home from dinner last night with the GF and this gut kept driving at 50mph in like third gear so i jumped on him, then we stopped at a light and talked. He said he didn't have traction(which i dont either) so i sugested a 10mph roll. He agreed and off we went! I whooped his ass from 10-120 by about 2.5-3 lengths. :devil: Couldn't have been a better night. He said he was stock, however he had atleast a catback. Damn those supercharchers really whine! :cheers:

:cheers: :burn: awsome kill....for so little mods....

What kinda car are you driving? Sounds like the dood needs some driving lessons...

i saw this new fangled mach 1 in the parking deck at work? mustang it has a plastic ram air looking thing, anyone know if they are fast or furious?

Mach 1's are quick, I've heard of some running high 12's stock. The 03-04 Cobras, Yeah, I race daily and I only have gotten beat once, and it was by an '04 Cobra, He romped my ass wide open FYI. Pulled about 3 cars on me in no time. I only dyno'd about 330 though.

Mach 1s are quick? Maybe compared to a stock civic. I know plenty of stock LS1s that have beat Mach 1s time and again.

Are you sure that was an 03-04 Cobra? From a dig you don't have a chance unless he can't drive. It gets even worse going from a roll. I would bet it was a 99+ cobra that you ran. :secret:

Damn those supercharchers really whine! :cheers:

I dont think 99 Cobras had this unless he had a bad serpentine belt. :devil:

Good kill. Haven't gotten to race a snake yet.

are you talking about the shaker? And i ran into an 03 cobra when my car was still stock. Whooped me pretty bad. All i had was a lid.......

My very first race at Jax Raceway in my truck was against an 03' cobra with less than 1000 miles on it. Granted he was still learning how to drive it, but I still beat him by half a truck length. I ran a 8.8? and he ran a 8.9?. With a good driver it would have beat me, unless i spray.

I raced an '03 Cobra last week on the highway. We started in third gear and by the end of fourth I was at least 1 1/2 cars ahead of him and still pulling. I pulled up next to him again this week and he didn't want to get beat again.

I sell Fords, the Cobras drive really well but they weigh too much. I can see how just a few mods on a Cobra would make a big difference. Mach 1's have the '99 - '01 Cobra DOHC motor with 305 HP. They are no match for any LS1.

i have a buddy with one, he has a cold air, nitto drags,short throw shifter,upgraded blower pulley (15lbs boost),true duals x pipe no cats, and a flip chip, one for his nitrous and the other for when he's not running it..The car runs like CRAP when he is on nitrous he is going to bow it up im sure. He smokes my ass daily. :whip: yes those huffers are loud but after his dual setup you cant hear it anymore it sounds like damn open headers!!! I gotta grow a serious pair and spend some cash to keep up with him.

id have to say the original poster has enough mods to edge out a stockish 03-04 cobra.nice job!


as far as mach 1s running 12s stock highly unlikely.theyre considerably slower than an m6 fbody.a4 3.23 ls1 and a mach is a good matchup.

What kinda car are you driving? Sounds like the dood needs some driving lessons...Yep, sure does. Still...as we say in the street racing forum..."a kill is a kill" and "anything can happen on the street".

...and yes, I have raced an '03 Cobra. ;) They are not invincable, but can be pretty quick. You're best bet is from a dig. Pulling a modded one from a roll is going to be difficult.

edit: The very first pass I made at the track was only a 13.6. It just happened to be the first time I raced an M6 at the track too. My two left feet were on the brake the majority of the time. The moral of the story is that cars sometimes aren't driven to their full potential. Fortunately I can drive it a tad better now. I'm looking to shave off about 3 seconds off that 13.6 this spring. ;)

Happy hunting! :)

Even if the guy was a bad driver pulled in every gear! Clutches fully engaged, petals to the floor and just holding on i pulled. By the way my most recent track time was.....
a 13.08 @113.56 a 2.314 60' and a .538 reaction. Horrible traction with the F1's.

But the MPH was pretty good??????

If you could hear the blower then that means he had a CAI or something because when there stock you can harley hear the whine from the blower.When my WS6 was stock with just a lid I walked 2 stock 03 cobras from a roll.

A guy from the cobra forums just ran a best of 12.8 @ 108 with ET streets and a CAI with an 04 cobra.Just goes to show that not all of them run mid 12s stock.

I've seen Z06's run 14.0's at the track. I wonder what J-Rod would do in it...maybe an 11.9x? I'm saying only that you should be careful with '03 Cobras. They can be a monster. A 13.08 isn't going to cut it against most stock ones even.

Definitely a nice kill though. :cheers: The guy was probably thinking WTF? :huh:

If you could hear the blower then that means he had a CAI or something because when there stock you can harley hear the whine from the blower.Not necessarily, the stock 3.65 pulley makes the blower whine loud enough to hear over a catback system at WOT...from inside or outside the car. Maybe your own exhaust drowned out the whine?

Especially when they are brand new. They get quicker after some miles get put on them...as do LS1's.

That is a great time for an almost stock M6 car. Are you leaving some mods out in your sig? Maybe I'm not reading it right :huh:

Mach 1s are quick? Maybe compared to a stock civic. I know plenty of stock LS1s that have beat Mach 1s time and again.

Sarcasm.

OCSSleeper, off topic, but do u have any sound clips of your exhaust?? if not can u tell me if it has a lot of interior noise???

My exhaust sounds awsome to me, my buddy has loud mouth which is slightly louder, but the A-Thunder screams on top end! To me it just sounds a little more crisp than the LM whicjh can sound gurgly at times. No affense to any LM owners.
oh, and sorry no sound clips. im not to good with the computer stuff. I doubt i can even post a picture if I wanted to. To get a ggod idea about what it sounds like, uncap it and its the exact same only quieter. But the Flowmaster does not change the sound just quiets it.

Get yourself a cutout. That catback does not flow well.

Haven't raced one yet but I know better. I test drove one and I was like whooaa. I think I have 4.56s in my M6 and I would have to shift to much. I wanted 4.10s put in but I think 4.56s got put in. When I drove the Cobra the traction control was on most of the test drive and I was like what is wrong with this car. Then I turned it off and man that car rocks. I am about to get Kook's LTs with a ORY. Then I'll change the gears. Then I hope I'll be close to keeping up with one. Good kill by the way.

Yeah the 03 Cobras are pretty sick, Two of my friends have them one with just exhaust and the other with chip/pulley/exhaust. I have never raced them in my LS1....yet. But ive driven both and with 470 rwhp its not hard to light them up 70mph. Thats the worst thing about the 03's is their traction. With any moded 03 you will just spin or wheel hop.

I don't understand, the 03' Cobra has like 390 HP stock. With your mods I don't see how you could beat one. Only unless the guy didn't know how to drive.

am going to throw my 2 cents here... friend has an 03 Mach 1. pretty close to stock a Z can take it (but close)

as for the 04 Cobra.... i did not race one persay, but me and this guy were playing around so to speak and he showed me what it was about. I must say, that mods need to happen to the Z or SS to take the cobra from a dig or from a roll

coker

I have raced an 04 cobra about 3 weeks ago . From a dig i killed him
to about 90 then we came up on some cars , then we whent from 60mph and he pulled on me NOT TO BAD, must be the SC.

unit213 You say that they get faster with miles?I hope so because my wife walked my cobra like it was tied to a tree. :emb:

We went from a third gear roll so there was no driver input involved.She was laghing at me so I will have a KB or a Whipple within the next couple of weeks. :jest:

Then she is going to get a big surprise :jest:

I've never raced one yet, but did see them at the track. Two of them, one with BFG drags and one with stock tires. The guy with the bfgs was running between 12.6-13.3. Very inconsistant. The guy with the stock tires was running about 13.0s. I usually run between 13.0-12.8 but thats because I lounch like a pussy with 2.0 60s. For fear of limping home. Oh I only have simple bolt-ons. I would not be afraid to race a stock 03-04 'bra, but if that thing is rour'n or wining, I'm stay'n away. My buddy has a 03 vert, keeps say'n he wants to run. I say "BRING IT". He dynoed 375rwhp, but I think I can take the heavy vert without traction.

Mach 1s are quick? Maybe compared to a stock civic. I know plenty of stock LS1s that have beat Mach 1s time and again.
hahah

The cutout is soon to be on its way(perhaps the next week or two). But thanks for the advice. Anymore? By the way every one who has raced me or riden in my car thinks I too have a freak. Im looking for a dyno in Orange County so I can get real numbers.************* OH AND YES THEY HAVE 390 HP AT THE FLY, BUT LS1 GUYS ARE PUTTING AROUND 325 TO THE GROUND, WHAT FLYWHEEL POWER DO YOU THINK THAT IS Bklynstranger! IM NOT MEANING TO BE RUDE BUT THEY ALSO WEIGH 3800 LBS. THAT IS A FAT ASS CAR!

Dude, it's not being rude. I didn't post that to start on on-line fight. I'm just surprised to hear that an LS1 could seriously take the 03' Cobra. Dude, I live in New York City; therefore, I don't often come across serious sport cars. I would love to see a serious clip of an F-Body going up against the 03' Cobra. Buy anyway, it's all good, it's about learning. I can't wait to move to Charlotte to seriously test drive an F-Body.

No I Just Didn't Want To Start A Fight Either, Its Just That Some People Unlike U And Me Take Things The Wrong Way. Its All Cool.......me And My Friend(he Has A Gn) Will Have Some Pics Or Videos Of Us Beating Up This Local Cobra In The Next Few Weeks. He Only Has Exhaust, And No $$$$ Because He Is Paying Like $500 A Month For The Car Itself. That Means No Other Money For Mods.

Thats it , I'm calling BS. NO WAY an M6 with a lid and muffler traps 113mph in the 1/4 on street tires. Then again you have an MAF...cmon now :eyes:

And kiss your stock 10 bolt goodbye with 315's. Sorry, I had a tough Monday. Good luck.

I have had 315 for two years and no problems with the ten bolt.My car has a filter ,lid and mac headers with the stock exhaust and it trapped @ 114. :drive:

OH ya full weight with no tricks. :)

OK, my turn to put my $0.02 in. Just want to say my 2000 Z28 M6, w/224 cam and alot of bolt ons ran a best 12.1@110. If i beat an 03' cobra with my truck, i know my Z would beat the sh#t out of one. Oh, by the way, that was with stock 245/50R16s. My truck ran a best ON STREET TIRES of 12.89@115(with the spray)

T-maxx, Man Just Take It What Its Worth What Do I Get Out Of Posting My Trap Of 113? In Reality I Don't Get A Damn Thing And Nobody Knows Who I Am Either. So I Would Be Lying For What? I Don't Know What To Say, Ok I Did't Trap 113, But In Reality I Really Did! Ps I Also Have A Professionally Ported Tb Open To 80 Mm, Ahpp3, And Asp Pulleys. Not Just A Lid And Catback! Sorry I Guess U Think Im Trying To Get Famous. Sorry No Hard Fellings. Oh And Yes I Have Some Suspension Mods If That Matters Too!

:funny: OCSSleeper, i dont know you but i like you already.

I know that I am new to this fourm but I believe OSCSleeper because I have a 01 SS and my best time at the track with only a LID and the FRA and gutted cats was 13.009 at 112mph and that was on the Eagle F1's. My best time on a set of Nitto's was 12.945 at 110mph. Next I have raced a 03 cobra at the track and on the streets. I have a friend with a 03 and the only mod he had then was a cat back system( I think a Bassinni) I hope I spelled that right. The first race at the track I beat him by a 1/2 a car. My friend said that he was still getting use to the car. The second race was a blow out because I didn't turn off the traction control. The 3rd race was a classic. I cut a .507 light and the cobra cut a .513. By second gear that cobra cam right by me with no problems. Third gear the cobra was a good 1-1/2 cars in front of me and at the top of 3rd it begain to even out . I must say that the car is pretty quick and if the person in it nows how to drive it it's going to be tough to beat it stock. Now this summer I will race him again. He now has the pulley,chip, full exhuast from the headers back(no cats) CAI, and he is having his S/C polished in the inside or something like that. I will have heads AS 5.3 stage2, cam 230/230, pulley, ported throttle body, 4:10 gears,kooks Lt & ORY(no cats)dyno tune and NX100 shot. Do you think I can take him or what? I think I should kick his ass but that's just my opinion.

You all can disagree with me, but I'm trying to make some conservative estimates that back his kill.

A) Say Your mods are probably giving you .3 (.1 for pulley, .2 for lid, exhaust and TB). M6's have been known to run 12.9 stock, so maybe your car is capable of 12.8. Your trap speed suggests this. Plus you had trouble launching at the track, as evidenced by your 60', 1/4 mile and trap speed, so we can't trust those 1/4 times, and your trap speed is :hail: So let's say that given traction you could run a 12.8.
C) Cobras have more hp, but they weigh 250lbs more and who knows how good of a driver this guy was and they seem to be inconsistent.
D) If they can run anywhere from 12.6-13's stock, as stated by some of the other posters, and you can probably run a 12.8 easily with traction and your mods, and you went from 10mph, thereby eliminating some of your traction problems, I don't see why you COULDN'T win.

Does it make sense that a 330hp car can beat a 390hp? Maybe, if you stop dyno racing and consider all the factors involved.

A) On the best day, with the best driver, and with great track prep an Ls1 M6 on Eagle F1's with a lid, and even some tuning might run in the high 12's..Maybe. I have never seen this only rumors.

B)= missing

C) A street race does depend on the other driver. I agree.

D) You say 12.8 easily with those mods, NO. To run a 13 and under It will take at least DR's and or headers. Weight reduction goes a long ways also.

E) Where did he run? Post a time slip please. :drive:

The 2003 Cobra puts roughly 355 to 365 to the wheels but is about 300 pounds heavier. If you go by power to weight and factor in the gained hp on the LS-1, a 325 to 330 hp car can beat a 355 hp car. I've raced 2 2003 Cobras. The first guy couldn't shift worth crap so we looked like a freaking slinky (because I was completely stock). The second 1 I pulled in every gear and I'm only running about 360 hp. The sealed ram air helped I'm guessing after about 65 but the major difference was weight. We both had traction issues. At about 115 I had about 2 or so car lengths.

The 2003 Cobra puts roughly 355 to 365 to the wheels but is about 300 pounds heavier.
Those are low numbers for a stock '03 Cobra...370-385rwhp is quite common.

Yep. Unfortunately I didn't get a before dyno. The people who worked on my car stated I was one of the stronger cars they've dynoed. In fact Heffners dyno is notoriously low.

As for the hp of the Cobra's. 2 of the car clubs I frequent here in the MD, DC area have a ton of 2003+ Cobras and the average hp stock on the dyno has been around 360.

My friends and I must've gotten lucky then. We were all in the 380's on a dynojet. There is an issue with clogged cats too. You might here of an '03 Cobra laying down 330rwhp...that's why. Just fyi...

One of the board members here (Seahawk) who's a local ran a 12.75 @ 109mph with nothing but an SLP option equipped (SLP lid, suspension and dual/dual exhaust) '01 Firehawk that had MAF ends as his only mod... this was on Firehawk SZ50s, no DRs and no weight reduction. So it is possible...

[QUOTE=ESMsilver00SS] Mach 1's have the '99 - '01 Cobra DOHC motor with 305 HP. QUOTE]

Actually ... the only thing similar about the 99-01 cobra motor and the Mach Motor is that they are both 4.6 DOHC.... they are a totally different motor ... different design block totally different heads diff. cams ... nothing is the same

well all i know is an 03 cobra with a 100 shot is fast lol. bunch of us went out racing, it was a vert, he said it was stock so we were all expecting to show him up, well only one of us beat him but his car would rape everyone else too, i was sad, need more power! my friends step dad has a cobra and SOTP feel yeah its fast but i dont think it would take me at all. then again its stock and there is a lot of potential out of these, cold air kits good for like 25-30 rwhp i have seen thats good, but boost also goest up 1 lb so you have to be careful lol

I've raced a Mach1 on the street....the guy couldn't drive very well...so we went from every speed imaginable to try and take driver skill out of the equation. I took him from every speed.....I would start to inch away as we hit 70 mph...and I had nothing but a lid on my 3.23 A4 vert.

As for newer Cobras......at the track I've seen them run 13.0-12.8 @ 110-113......heck....most stock M6 LS1's are very capable of those times....let alone slightly modded ones....and a stock A4 with a torque converter can run those times all night long.

Yes, there is the Mustang dyno which dynos lower.

In fact Heffners dyno is notoriously low.



Really? That's where I dyno'd. Can you elaborate?

What happened to B?

I wanted to make sure you guys were paying attention. :emb:

Mach 1s are quick? Maybe compared to a stock civic. I know plenty of stock LS1s that have beat Mach 1s time and again.
Agreed. Mach 1s are not anything special.

Just like LS1's, there aren't many stock '03 Cobras out there. I completely skipped 12's with minor mods.

I've raced one 03 Cobra back in October back when I had 366rwhp @ 351 rwtq. He had stock exhaust and at most a CAI as I could hear his blower whining pretty good. He was by himself and my Dad 250+ lbs was riding shotgun with me. We went from 80+ mph rolls and he pulled 1/2 car on me to the top of 4th. On the second round I did the same to him from the same speeds. We were so close it came down to who got the better jump.

PS I had all the mods in my sig when I raced minus the QTEC but the reason my power was so low was because I had a 3" Car Chemistry Baffle inside my I pipe that was choking the hell out of my engine although it did take away all the raspiness. By manually opening up my cutout I gained 33rwhp @ 34rwtq. I would have loved to have had that QTEC on at that race time as the Cobra would have been seeing my CME and that's all!

http://www.imagestation.com/picture/sraid95/pd3d0b45ffc46fd7640f2b675b517897b/fa2479a3.jpg
Red lines were my power levels when I raced the 03!

33 And 34 GAIN?! Sounds like you had a rodent trapped in there.

well just to share a little info from the other side of the fence.....i have seen a bone stock cobra go 12.50's at 112 and i have seen them run 13.30's,all in the driver.have heard of faster cobras stock but just havent seen it with my own eyes.

on the machs i can testify that bone stock with a drag radial mine went 12.97 at 106.56 and with street tires went low 13's all trhe time.a couple peaple i know went high 12's bone stock in there machs.

i have yet to loose to a stock ls1 car!!!not saying it wont happen but havent been unlucky enough to loose yet.

isnt it funny how the ls1 guys with stock or close to stock setups say they never loose to the machs and the machs say they never loose to the ls1 guys.makes you wonder who's lying. :judge:

isnt it funny how the ls1 guys with stock or close to stock setups say they never loose to the machs and the machs say they never loose to the ls1 guys.makes you wonder who's lying. :judge:
I think the majority of people with stock cars really have no idea what fast is. As a result, they feel their car is unstoppable so they talk alot of :bs:

yea that sounds about right.

also like unit was saying anything can happen on the street.i beat a car that runs 11.60's on the street but no traction took the horsepower equation out of it. :)

Just like LS1's, there aren't many stock '03 Cobras out there. I completely skipped 12's with minor mods.
exactly, with just a pulley, chip, and exhaust they go right past bolt-on LS1 territory

It seems safe to say that a full bolt-on Ls1 is a good ( close ) race for a stock 03-04 Cobra. Not an Ls1 with a lid and Flowmaster, sorry OCSSleeper. I wish it were the other way around :buttkick:

Really? That's where I dyno'd. Can you elaborate?

Some of the guys who work with Heffners were talking about this the day I dynoed and it was mentioned later on. I don't know the specifics but people were dynoing a little higher on some other dyno's.

I disagree. A FULL bolt-on LS1 will destroy...and I mean DESTROY a stock '03/'04 Cobra. Have you seen the LS1 bolt-on list? It's no joke.

Dont listen to unit213 hes never raced a 03+ Cobra. :devil:

I was speaking of Ryan02SS post. It looks like he has most of the big bolt-on's. Maybe I shouldn't have said "FULL". UNIT what did your car run in stock trim? I just can't believe that an Ls1 with a lid and other minor mod's can take an 03-04 Cobra. I have yet to see it happen on the street.

Yup, Unit is just a bench racer... :secret:
