also IMO the 350 small blocks like ls1 or ls6 are among the best engines out there the only egine i would take over it is the 345 hemi wich is more expensive.

And for a good damn reason. :D

ok and you are back and attcking redneck this time. Please watch your language pal redneck's post was disagreing with you but he not disrespectful so if you want to make your point please be polite about it.

he got what he deserved for flying off the handle---just to ignite the issue. As most guys do in this forum--they pick one idea out of so many---and spring board into a rant and rave about something that was never challenged to begin with!

Why not make the Cobra not weigh as much as a damn truck? It isn't Chevy's fault that Ford can't make the Mustang light.

Also, back off, you are getting close a personal attack there.

Hey redneck, nice use of my car in your example, I think that helped out alot:hehehe:

Now a Camaro SS with its 330hp LS1, runs a 13.7 in the 1/4 mile with its 3400+lbs

What confuses me about these cars is if thats around what they run, how the hell did some Ford website that svt5.0 posted (03 Cobra vs 35th Camaro) managed a 13.1 in the SS? It's not like it was some plain jane Camaro SS either it was one of the 35th Anniversary Editions, red with stripes and all that, so it was probably fully loaded.

01 and 02 Z28's and SS's have LS6 intake plenums and whatever exhaust was ordered with them, so they're more free flowing. If someone knows how to drive them, it's not hard for them to be low 13 cars...

My times are 13.5's, so you know I have practice to do :D

hey guys, i hear "ls1" an all that stuff...i mean, i'm a lil familiar w/ 305's 350's etc etc...but wut exactly are most of the stats of the new motors (ls1's etc...) is it basically like honda's "b16...b18..." etc..?

Whats the difference in a b16 and a b18? They might be something similar but I don't have a clue about Honda engines.

well...b16' is found in a bunch of cars...was found in earli gen civics (not in the states tho), then del sols (yes i kno its still a considered a civic) an all the way up to the 99-00 si's. b18's are found in 3rd gen teg's. from 94-01 they were used an are now replaced by the k series motors in the rsx. so its jus names basically...is that wut "ls1" an things like that are?

An LS1 is a 5.7L(350cu) V8 engine found in 97+ Camaro's and Firebirds.
It's 305hp or 320hp depending on the trim and 325ft-lbs of torque if I remember right.

A 13.7 quarter in an LS1 is INCREDIBLY SLOW. If anyone drives that in their LS1 they need a new car(b/c they got a lemon) and they need driving lessons. Even you BlkCamaroSS, heheh, need to get back to the track and pull a better time:D They run in the low 13s easily, straight from the factory. Seen it done too many times to count, and done it myself in an LS1 vehicle.

... haha Vortech... If I offended you somehow sorry man... I'd love to see what you said to me, but apparently I wasn't online in time to see your post. Maybe you can PM me your 'thoughts'?


I just want to see some hard evidence on the Z06, honestly If they were that bad you'd think more people would trade them in or you'd read about factory recalls. I know I haven't seen any but if you can point me in the general direction I'd love to read some stuff on it.


But believe me, I think the new Cobra is a sweet car... It gives you mustang owners something to be happy for... you can finally pass that SS on the freeway now!:silly2:

Seriously though, its a cool car. If I was some rich dude and had a stable of cars I'd probably have one...

Yup, I know this, I'll be back there this spring, after I get some new rubber:D .

As for your stats, LS1's have been in F-bodies since 98, not 97:p . Vettes had them in 97. Also, the 02 Firehawks and SS's could come with up to 345 flywheel hp:D

Yes, they've been in since 98. I meant they'd been around since 97, should have made that clear. Man, I didn't know you could purchase an SS with 345hp. THe Firehawk I knew, but didn't know also in the SS.

Yup, depended on all of the options you wanted. You could get SS's in 98-2000 with just 325 hp. In 2001, they added exhaust which they rated them at 335hp (could still get it with just 325), and in 2002, they added an airlid for a grand total of 345 hp (again, could get it in whatever options you wanted for 325, 335, or 345hp, just depended on what was ordered with the car). Same thing went for Firehawks:D

Mine was a 335hp SS in 2001.

thx for the information...

what mister self forgets is the altitude and the temperature. You come over here in utah at 4000 feet and do low 13 with and NA ls1.;)

so yeah in perfect conditions is easy to get low 13 but that is rare.

hahah, yea that's true. But that's not the fault of the car. It's still capable of a low low 13 second pass:p

LOL, thanks for the enthusiasm, but at 4k feet, I think I'd take that bet against myself, hahah:D

heres a Z06 with conversion kit ,eliminated cats, true 3"exhaust, cold air intake, bigger injectors before and after my adjustment. This is the best Z06 I've run on the dyno out of about 60. I think its sad based on the 4000 dollars the owner spent extra besides the car. And as far as the ss numbers I've honestly never seen those kind of dyno numbers on them they usually pull around 275 until the idiot owners modify them in the wrong way and they tend to pull around 250. Sorry buts it's what i see and make money off of every day.

Thank you for some proof to your arguement...

Now allow me to do some ricer math:D

Not exactly accurate but... it shows kinda what I'm saying.

Ok, we'll use that top dyno run of 370rwhp from that Z06.

405bhp to 370rwhp equals an approximate 9% powertrain loss. I know the Z06 has some trick stuff but i dont think its that trick.

Now going off the common guestimate that the T56/Driveshaft/Rearend suck up around 15% of the total output of power...

But If you add 15% to the 370, thats 425bhp from the Z06.

Granted this is a modified Z06... maybe it wasnt tuned correctly so it wasnt making its full potiential.. or maybe it was? I cant say i'm not an expert.

As for the SS numbers, BlkCamaroSS's car is making some nice numbers for a more or less stock LS1. Not to sound like a dick cause I'm not trying to be... but any comments on that? He's only got a few SLP products... I doubt they'd help him that much from what you say you've seen on the dyno.

Check out http://www.camaroz28.com . I'm a senior member over there, and I can tell you that there are over 100 guys on there who pulled over 300rwhp in their stock LS1 Z28 and Trans Ams. And that site doesn't even have many LS1 owners(as opposed to http://www.ls1.com). These cars are pretty much my life, I've seen more dyno runs than I could ever even begin to count, and more track passes than John Force himself:D If you have an LS1 and it isn't pulling over 300rwhp, you have a lemon, and if you have a Z06 and it isn't pulling over 350rwhp, you have a lemon.

Below are numerous examples from buddies of mine on camaroz28.com and ls1.com about the stock or very-near stock power output of the LS1 engine found in 98+ Camaro's and Firebirds. Take a peek through them and I think you'll find out that the LS1 is a very strong and very underrated motor. AND in addition to that, here is the link to an entire thread entitled "underrated ls1" that's over on camaroz28.com. A thread dedicated to this very topic.

'02 LS6 cam dyno results within'
My car is a 2002 A4 Camaro SS with the SLP "345 HP package". It has SLP's lid (which was shown to be a POS) and the centermount exhaust. I dyno'd it bone stock with 722 miles on it and it put down 311.8/320.8. I switched just the lid (from SLP to a direct flo) and it put down 319.9/329.4. That was 7 days ago. Since then, the only mod done was the '02 LS6 cam swap. I finished it this morning and took it over to the dyno this afternoon. Air temp was almost identical and the Barom. pressure for the stock runs were 30.32, and today they were 29.92.

It put down 352.6RWHP at 6200 RPM and was still climbing slightly (stock rev limiter), and 343.7 RWTQ at 4800 RPM. So with just adding the '02 LS6 cam, I gained 32.7 RWHP and 14.3 RWTQ.

This is through an automatic, stock manifolds and stock cats, my 18" HRE's, and no dyno tricks. Tomorrow I'm having an off road y-pipe made and I'll be putting my TR ported TB on and re-dynoing tomorrow afternoon. I will post the dyno graphs in a few days (when I have a friend do it for me).

So, my car sounds dead stock, looks dead stock and makes 350+ RWHP through an automatic I am very pleased with the results! Not too bad for $350 total.

Yeah, it's a highly agreed upon "fact" (or belief?! ) that the F-body LS1's are way under-rated compared to the 'Vettes. The proof is when guys dyno their stock F-bodies, and they put over 300HP to the wheels. For a car that's only rated at 305-310HP at the crank, it's amazing that often times ~310+ HP goes to the wheels?!

I think Its great you guys are pulling numbers on the dyno better than this Z06, honestly i think gm would notice that and change it. Thats why the vette is their top of the line sports car. But as to redneck the Z06 gained 50 rwhp with the illegal upgraded exhaust:)
The problem is everything you do to those things is either custom fabrication, or very expensive bolt ons. The camaros are much more economical and great hp numbers can be achieved with alot less money I'm just saying I've never seen those kind of stock or semi stock numbers. I'd just like to see some dyno sheets thats all. I'll start with one from my car so you guys at least know I do Know how to build a car:)

Great sheet, especially on the torque side of things. What's the huge drop about though? And also, what size cam are you running?

I'm not sure, but if you've never seen an LS1 Camaro/Firebird pull numbers of at least mine or higher on your dyno, and the Z06's dyno'd there are coming up sluggish, I'd say your dyno needs to be looked at. Something may be calibrated wrong on it. And the benefit of this thinking would be, your cars are even stronger than you thought since they've been dyno'd at the same place:D ...

hey self. The cam is a custom from lunati 510/276 510/290. The real power came from Mcclure racing in texas what he does with trick flow heads is amazing. They're already great heads but some how you send him a pair and he gets 40 to 50hp more out of them. If anyone ever wants a strong engine thats reliable I recommend them. He warranties the motor for 12 months 12k miles. I couldn't even find anyone where i live that would warranty a performance motor after you picked it up. The drop on the dyno is a rev limiter and recovery curve.

Hey ss thats a good point I kinda hope the dyno is wrong that would make my numbers sky rocket:))) I'll let you guys know what the 03 cobra does on the dyno. Hopefully not to good I wouldn't want my wife beating all you GM guys:) She wouldn't settle for the GT or even the mach 1, had to be the Cobra, I hope she can't keep up with me:(. But if i let her maybe i'll get some extra attention:) Any one running nitrous on the ls1 motor? I'm curious to how it does.

I've never run nitrous on an LS1 motor, nor do I know many guys here doing it either. I know a guy that's shipped off to Iraq that was gonna put a nitrous system on his Corvette, but I don't think he got that accomplished before he was shipped out...:(

My friend Carson runs a 150hp wet shot on his 98 Z28. Besides the nitrous he has an intake, longtube headers, and Borla exhaust. His hp was pegged right at 483rwhp I think it was. I might have his dyno sheet somewhere on my comp, I'll try and find it.

Can you get any more RPMs out of that? Looks to me like the peak HP is coming right at about 5500 or so. No more power left in it after that with that cam?

Damn, can't find a pic of the dyno sheet, but I have a couple pics of his setup and of his car on the dyno...

http://filebox.vt.edu/users/mself/forumspics/carsonz283.jpg

Thats a goodlooking nitrous set up. alot of people make the mistake of putting the nitrous too close to the intake and the mixture usually is too strong or weak for one side of the motor. He's got the perfect placing.

Hey SS, I have rev limitersfor that rpm only because of block life:) especially when i use the nitrous. My rpm range is about 7000 but the motor peaks at 6200. I just try to get as much life out of it as i can. Not just cost but the vette motor is a bitch of a motor to change, the whole drivetrain has to come out:(

I'll dig up a pic of the setup i have and load it in to show you guys.

Self was the one asking about the cam stuff, I'm just along for the ride now cause I don't know dick about nitrous...

Nitrous is safe and fun if used properly. And it will not effect your engine if it's set up properly. here's a pic as another example. On mine, each side of the air box is 2 solenoids small for first stage and large for second. this is the best way so your motor doesn't get the initial bang from the juice. If set up right the power will be so smooth you'll think the car is running natural hp.

What size jets, fuel and nitrous are you running?

All kinds of good and bad information here, I've read all 15 pages of this thing.

That being said, I'll stick to what I know.

15% drivetrain loss is pretty slick. T-5 Mustang about 17%, C-4 Auto 19%, AOD 22%. 2003 Cobra, about 19%

The average 03 Cobra puts down about 360rwhp bone stock, or right about 440hp at the crank.

The Z06 will have significantly more than 15% power loss due to the T-56, and the fact it has IRS. IRS isn't as efficient as a solid axle setup, and it'll usually cost you 2% or so in dynoing.

405hp at the crank would probably ring up to about 330rwhp. Stock LS1's dynoing at over 300rwhp, who knows? I've seen a lot of data supporting it, but then again, I've seen a LOT of faulty dyno numbers too. The trap speed will verify rwhp. An LS1 Fbody will weigh in about 3400lbs, and most run 106-108mph traps with a good driver, correct me if anybody feels I'm wrong here. If a Z06 puts down 330rwhp, and the LS1 F body makes 300rwhp, you're actually seeing a difference of nearly 40hp. The fact is, the F body doesn't make 300rwhp on paper. Not even close. The trap speeds simply do not support it. Even a very strong 108mph trap would tell me the F body is making over 40hp less than the weakest Z06. I can't say they do or don't to be honest. Just that it's always bugged me a great deal that the trap speed doesn't add up to the paper horsepower.

The Z06 is closer to 115-118mph, and the Cobra picks it up in the 111-114 range. The Z06 is a low/mid 12 second car. The 2003 Cobra is a mid 12second car. Car for car, the Z06 is quicker than the 2003 Cobra, and weight is the ONLY factor for this being true. The 3650lb Cobra gives up 500lbs to a Z06, and you're talking several tenths just because of that.

The 87-92 Mustang 5.0 simply owned the F-body. TPI or not, the F body weighed about 300lbs more than the 5.0, which is most certainly NOT a 15second car as quoted. Anybody worth their salt can pull a mid 14 from a tuned 87-93 5.0, stock. The 350 TPI cars don't impress me, to be honest. Everybody talks about it's torque/hp, but they don't bother looking at the powerband. The 350 dies FAST because of restrictive components so you wind up short shifting, and horsepower advantage is largely nullified.

With all the people talking about how poorly the Mustang handles, I can only assume they've never driven one. The 99GT beat the Integra Type R solidly on a road race course when driven by Sport Compact Magazine. They intentionally wanted the R to win, and basically proved they couldn't drive the GT. To be fair, the Type R won by something like a tenth of a second on their ultra tight course.

To the S2000 owner who thinks he's got torque, heh. A flat torque curve doesn't mean you've got around town torque. My FZR 600 sportbike and even the newer R6's have a flat torque curve. They just simply have an itty bitty number that it stays at. Simply put, the S2000 will get beat by the average Civic, both shifted at the same RPM. You do have the beat the heck of the S2000 to get it to go.

The Mustang Cobra is currently so heavy because Ford decided to use a cast iron block and all forged internals for the engine. That adds a ton of weight on what was an aluminum block. The 4.6L isn't a lightweight, even in the aluminum block Cobra's, you're talking 530lbs or so. You can figure the 03 Cobra's engine weighs at least 650-700.

The real true bottom line is that ANY car can be made fast, and be made to do it in the way you prefer; however, most people have a limited budget on what they can do it on, and they need the car to perform a number of different functions while they own it.

The 2003 Cobra is probably the best car at providing utility, performance, and cost of any of the cars listed here. More than 400hp, room for 4 (in a pinch), under $35,000, a semi-functional trunk, and more suspension/drivetrain enhancements than any other significant production Ford Mustang in history.

For what it's worth, I think I'd take a 2003 Cobra in Sonic Blue over any of the cars listed here in appearance as well.

What components are restricting the L98 350 from beating a 5.0L Ford? I never heard of a case that the 5.0 was faster than it. The only thing I've heard is Chevy's 305 constantly losing to the 302.

Also, Was the Mustang 5.0L capable of beating the 89 Turbo Trans Am? No. What about the Pontiac Firehawk putting over 350 hp in the early 90's? Doubt it.

Late to thread.
Here's proof mechanic69 that LS1s put down over 300rwhp. The car is bone stock down to the paper filter. It's an '02 with the SLP Y2Y 335HP exhaust package. I'm keeping it stock till I get some baseline runs at the strip. The '02s break into the 12s with sub 2.0 sec 60 ft times and good air at 107-108mph(A4) or 109-110(M6).

Take a look at the automatic ONLY L98 350, which was available in automatic ONLY. That combination made peak power 240hp@4400rpm, and peak torque 345lb/ft@3200rpm. The TPI 305 was sitting at 230@4400rpm, and 300lb/ft@3200rpm.

The 5.0 Mustang was 225hp@4200rpm, and 300lb/ft@3200rpm. They all have exactly the same ratings, but if you look at the power band of the 350, it dies fast after making it's peak power.

http://chuckb.1le.net/archive/past_cars/87_formula_350/formula_350_dyno1.html

That's a lightly modded L98 to show. It drops over 50hp at the crank between 4200rpm and 5200rpm. That's with the intake being helped out by porting, etc. On top of the quick falling powerband, you contend with a lot of extra weight. The F body weighed 300lbs more than the Ford apples to apples. Throw the L98 into the equation, and now you have an automatic that will add another 50lbs, easily. The automatic also has wider gear ratios which hurts the L98 especially hard due to it's narrow power band.

In short, the speed density 87-88 (non California) Mustang 5.0s were high 13 cars with free mods, and an excellent driver. An average driver would see low 14's with freebies.

The Turbo Trans Am was a 1500 car production run, limited edition, annivarsary edition. It was faster than the fox body Mustangs of the era. Basically, it was a Grand National engine stuffed under the hood of a T/A.

If they're seeing 110mph traps, bone stock, then I'd be willing to believe the claim they have 300rwhp.

What has GM done to the cars to extract the additional 20-25rwhp the 98 LS1's had?

I think somebody mentioned the LS6 intake, and you just mentioned the SLP exhaust package.

2000 - redesigned exhaust manifolds (+5 rwhp)
2001 - LS6 intake (+15 rwhp)

Thats a pretty interesting graph. I've never come into a race with a Mustang 5.0 with the Firebird, stock or modified. I'd really like to see what the 350 does against one now. I still have my doubts that the Mustang 5.0L was faster though, I mean do you have any other charts from maybe a Iroc-Z28 with the 350? I remember someone saying the Camaros were a bit faster then the 3rdGen Firebird. I just need to find a damn stock Mustang 5.0.

As far as being impressed with that L98, I ask you what the hell was impressive about the 80's anyways? The 80's pretty much sucked all the way from the music, clothes, hairstyles (mullet :rolleyes: ), and of course cars. Just about every motor from the 80's was horrible, hooray for 230 hp V8's :o

A guy that lives next door has a bone stock 92 GT that with just a short belt and advanced timming ran a 13.65 in the 1/4. I think thats pretty impressive for an 11 year old car.

And all this for less than $36,000. this my friends can not be beat.
i got something that would kill it

all for around $22,000. i think it runs 9's on street tires.

:devil:

edit: here's the dyno slip. keep in mind this is 2600 lbs.

Since I've been the owner of an 87GT and an 88GT, my friend had an 87 LX 5.0, and another friend had an 87GT with T Tops, I've seen my fare share of races with the 5.0s. For what it's worth, we were all very lightly modded. Like K&N and a catback in most cases as there was simply no need to add more to whoop up on most unsuspecting opponents. I have never had an IROC, even with the TPI 305 come even close to giving me a run. It was an annihilation every time. My 87GT with 161k, and an ultra tall 2.95:1 first with the 2.73s in back killed my 02GT by 3 cars from 0-80, and pulled it on the freeway. Now I'm the first one to admit the 87-88 SD cars are stronger than the MAF cars, but my 02 is no slouch. It took my friend's 87 T-Top in a race pretty good out of the hole, and then pulled it on the freeway a little too. The T-Top car has 280,000 miles btw, and 140,000 on the rebuild.

Bottom line my kills on the street with my 87 include

3 LS1s: 1 SS vert, 1 WS6 hard top, 1 Z28 (Z28 from street start, WS6 from a stop, SS on the highway)
1 LT1: Z28 hard top
1 3000GTVR4
2 Grand Nationals
2 Fox Mustang 5.0s
1 70 340 Cuda with heads/intake/cam/carb/gears/drag radials that the owner thought would do 10s :bloated:
1 69 Charger with a built 383 (barely, though his crappy auto/tall gears made him easy killing from a stop :) )
1 93 FZR 600 (the bike's mine now, heh)

Good driving means just about everything on the street, and quite frankly with the nearest tracks (3 all about the same distance) all being 200 miles away charging anywhere from $80-140 to run so long as an event isn't scheduled, it's pretty tough for me to justify track running here.

That being said, my friends have also killed 96-98 Modular Cobra's, TPI 305 and 350 Camaro's, LT-1 Vette's, 3000GT's. My T-Top friend got beat by an LS1 by 1 car from 0-100mph. I've only been beaten 1 time in my 87. Against an LT-1 Vette in AZ. Scenario wasn't too good for me, but I still lost.

With minor mods the fox Mustang 5.0s can be killers, but in all honesty, I see way more people getting owned in their 5.0 or running 15's and they are just unable to break into the 14s. I have no idea why this is. :grey:

3 LS1s:
1 SS vert,
1 WS6 hard top,
1 Z28 (Z28 from street start, WS6 from a stop, SS on the highway)
1 3000GTVR4

With just a few minor things like a catback exhaust and you beat all these cars? How exactly did you do that? Missing a gear is one thing but Grand Nationals are automatic, it ain't hard to just mash the gas down to the floor and go. Thats quite an accomplishment.

The Ford Windsor 5.0 is a strong motor, and just a little work can get alot of power out of them. Still, as V8s go, it's kinda small ;)

With nitrous or forced induction, the 5.0 is a very powerful motor though... Billy Glidden runs mid 7 seconds 1/4s consistenly in his nitrous powered 5.0 based Mustang, and that's on a 10" tire.

The Grand National isn't some monster in bone stock form. Could be I ran across a couple stockers which more than likely would have been in the low 14s.

Turn up the boost, and get some exhaust on them, and they should have left me, though.

As far as the SS, it was a vert, the WS6 I killed off the line, and the Z28, well, just drove him probably.

Saying my 5.0 would have taken LS1s car vs car is ridiculous. I just can't see any way for it to do it. The fastest 5.0 like mine out there might have run 102mph through the traps. It simply didn't have the power to beat the LS1s. Doesn't mean I don't drive better or in the case if it killing my 02 GT, maybe there was a little work done to the heads I didn't know about or something. It's been a theory for a while that my "freak" 87 might have been the receipient of a little hidden help, lol. It was custom ordered with power window/lock/mirro/remote trunk release delete options.... strange...

I mean there's more to a quick time than weight and hp, so I know it's possible, I'm just wondering...

WHAT?!?!?! The Cobra is mid 12's 390 hp (underrated) with a six speed, an LSD, and 3.55's.

How does a 240hp S2K run a 13.2.... Last I heard they couldnt even break into the 13's....

Most don't. You have to constantly work with those finicky S2000's to get them to hook right for a low time. Most daily drivers on the street will never see a 13.2 run...

Who said anything about a 13.2??? They run a solid 14.2, definitely never seen a low 13 from a stock or near stock S2k. And I have yet to see an 03 Cobra run anything better than a 12.88. Which is fast, but definitely not Z06 territory in the least:)
Oh, and I SERIOUSLY doubt that 390hp is underrated. Why do you think it is? The traps and times don't say it's underrated at all, from what I've seen.

The 390 hp is underrated... Just look at the Dyno numbers. Let not forget that this Cobra wieghs over 3600 lbs. That explains why Z06's with similiar power numbers are running faster.

I haven't seen a cobra put down less that 340Rwhp... There are a couple that have put down OVER 370. Needless to say teh average numbers are between 340-370 RWHP. Just take a trip over to www.SVTperformance.com , We'll be happy to show you slips/dyno's/vids of PLENTY of Cobras going faster than 12.88... Hell MM&FF ran a 12.5 in theirs.

And the 13.2 was quoted from someone else in the thread... Which is impossible.

Oh yeah. THere are some guys with STOCK Z06's running in the 11's.

But let me ask you this. How easy do you think it is to get 500hp in a z06? How much will you spend? Now, how much do you think it will take for an 03 Cobra to get to that same power number? You dont even have to replace internals for it on the cobra. It is silly how many guys are running 425-275 RWHP on simple, simple, simple, bolt-ons!

Have fun!

Yeah I've seen that posted on a corvette website before as well, and I don't believe it at all. When I think stock I think right from the dealership nothing removed or changed (including exhaust cat-backs and headers) from the car with the exception of the spare tire. But then again other people have different definitions of stock, like stock engine but everything else is stripped down or modified. I have yet to see much proof of these Z06's making it into 11's either.

How easy do you think it is to get 500hp in a z06? How much will you spend? Now, how much do you think it will take for an 03 Cobra to get to that same power number
Flat out its most likely going to cost less with the Cobra. From what I saw in the Camaro SS vs 03 Cobra that Muscle Mustang & Fast Fords ran a 12.8 or .7 with the 03 Cobra not a 12.5. Thing is though regardless of how easy its going to be for you to get power out of that Cobra people are still going to have to dump a lot of cash into the car to make it a drag vehicle.

I've never really believed that underrated stuff either, even a lot of F-body owners claim their new cars are underrated. I just think its a lot of hype and fanatic bs from Ford and Chevy owners.

perhaps people are lieing about their mods of their cars, but I've seen many dyno graphs of 03 cobra's as well as LS1 F-bodies proving that thier advertised HP is underrated.

man Im tired of all this bull shit like the corvette is so much better than a cobra the stock cobra and stock corvette tie in the quarter mile and from everyone i have heard the cobra is faster in 0 to 60. I mean the cobra deserves way more credit then people give it. I got 415 rwhp just from cat back and mid pipe and i can take any corvette from 2002 and down im not tryin to start any fights but im tired of this shit the cobra cant touch the corvette thats such bull. i mean the corvette has way more status but were i live the cobra is way more exclusive.

the Cobra isn't a bad car its just no match for a Z06 corvette.
