Got bit...boy did it hurt!!

[rajiv1998]

The other day i was approaching a light on mountain ave and i see a black cobra sitting at the light. I slowly approach him and he revs it a few times, and i rev back letting him know its on. Well i put maybe 2 cars on him by second, but once i was going into third i heard this loud ass whiiiiiinnnnneeee, it sounded like a fucking fire engine and he blew by me as if i were standing still litterally. By far my worst death ever, that blower was SSCCCCRREEEAMING and the exhaust sounded nice as hell. All i saw after 3rd gear was his taillights, "COBRA" written on the bumper and huge rear tires (prolly 295's or so) He was defenatley just playing with me and allowing me to boost up my confidence. Man that hurt, which is why i wanna sell my car even faster to get one. Hopefully everything should work out and ill have one next year by this time. My car is like 90% stock, and he def had to have a pulley and exhaust and god knows what else was under the hood.

[ss~zoso~ss]

eh, get heads and a cam, and tune, and you'll be just as fast as a cobra

[Tyler_LS1]

This guy just has Full Exhaust and a 100 shot (and obviously a tune).. vs cobra

[rajiv1998]

Listen i dont wanna sound like a ... but for every one mod a cobra does and LS1 will hafta do 3. With these 4 mods (pulley, intake, exhaust, tune) even an average driver can send a cobra into the 11's. With those mods even the weakest running cobra will make over 400hp, and we al know there is no way an LS1 can do that w/o engine work. Sure a H/C can keep up with a pullied cobra and another few bolt ons, but what are you gonna do once they start porting the blower, change the intercooler and do even more mods, not to mention a KB cobra. Granatelli make coil packs for those cars and they add like 17hp, or so I saw on youtube lol. I dont wanna start a war, but thats how they came from the factory. Sure the LS1 has a more than a litre than the cobra, but the cobra makes up for that with a S/C.

[Tyler_LS1]

Nitrous is a quick fix! lol

[rajiv1998]

Nitrous is a quick fix! lol

yeah it is, but your risking blowing ur motor up everytime u use it on the stock bottom end, where as the cobra has forged internals PLUS a s/c from the factory so that motor will LOVE nitrous.

[Tyler_LS1]

its all in the tune

[MikeSomething]

I understand where you're coming from, but there's always something faster out there... Most people who have Termy's get tired of the S/C and swap em out for a turbo setup. Either way it's still money. You want something faster than an LS1, but what you don't understand is it's all about the preference of the actual car (looks etc.) you're driving man. Good luck tho!
:drivin:

[bene]

Forged internals, heads and cam, bigger cubes (LSx) and take a pick (turbo, ProCharged or nitrous)... What KB cobra?

Its all how deep is your pocket. KB kit isn't cheap for cobras so you're not going to run every cobra with KB.

[blackls1ta]

yeah it is, but your risking blowing ur motor up everytime u use it on the stock bottom end, where as the cobra has forged internals PLUS a s/c from the factory so that motor will LOVE nitrous.every one has their opinion heres mine,i like the terminators but i wud never sell my ta for one ,its your choice but i love my ta and will always stick to that,good luck on the mustang forums,lol

[adam3566]

The money your going to spend on a Cobra you can easily mod the hell out of your car or even a new motor if your tired of the ls1. New 408 with a 100 shot, what color was that cobra?

[Chris Arnold]

Honestly, you sound like a troll. Terminators are awesome cars, but so are LS1s. Modifcations are not cheap, but the initial investment in LS1s is cheap by comparison. What does it take to run with a modified Cobra? A modified LS1. Want to lose your money in depreciation or in modifications? It's your choice. It'll all work out about the same, though.

Chris

[Bigdeezs]

I was a good race for my buddy's 99GT in my Blazer with my 4.3 on squeeze but then the wiseguy had to go out and get a 03 Cobra:rant:...so I did what any normal person would do, I went LS1 with the same nitrous kit...still a good race!:zoom:

LOL and dont get me wrong LS1's are fast as hell but its not unstopable. As far as value goes, maybe the LS1 is the best bang for the buck to compete with a cobra, but that doesnt mean the LS1 is the only car in the world that will kill a cobra. Depreciation?? Automobiles depreciate the worst in value, and FYI cobras hold their value pretty well, much better than an LS1. I have yet to see a termi with about 50k miles go for anthing less than $20k.

Yeah, well if your LS1 car cost 35K new, then it would prolly have had a supercharger on it too and you would smoke 03's all day with a "pulley swap" and other Ford garbage lingo.

I don't get your argument, with money comes speed, whether initial or in mods.

03's are bad ass, but they are BAD on your wallet too. Used 03's are risky business, especially if they are already modded, which means they have prolly been beat down with hard mileage.

Anyway, go get your 03, and join a Ford forum. Till then, I will be laying down Termi's with my LS1. Then yours will be next.

[Frost]

headers and a P1 or D1 will make 550rwhp all day on a stock LS1 and is still inside of the safety margain.

I tuned a 98 SS with a only a cam, and a home made turbo kit with a 76GTS turbo and it laid down 638rwhp. STOCK BOTTOM. A lot of you will yell "it's not safe, it's not safe!!" .... well, it's been running and raced for 3 solid years at that level. The car traps 138. If you doubt it, goto the top right video on this page and see the dyno video; 3 pulls, 1 at 9psi, 1 at 10psi and the last one at 11psi. http://www.lsxtune.com/video.htm This car has crapped on many a Cobra with aftermarket blower... runs bottom 10s; has enough MPH to be in the 9s if he could get it to 60-foot better.

[180ls1]

well if you want a termi get one but you know the response you are going to get on this website. you are going to be pissed when this happens to you with your built cobra
http://www.youtube.com/watch?v=nbssfoqX9XA

and what do you want the cobra for road racing? street racing? or the strip? because for the strip a stalled geared a4 is hard to beat and they dont come in a cobra.

[MikeSomething]

heads and cam in LS1 can make over 400 to the ground :)
Wow, I can't wait to go to the track and look for some Snakes... :nana:

[Johns00Z28]

Yeah man the money you're gonna dump into a cobra, $20-25K can be invested into your car and you'll pretty much never have to worry about any cobra.

[98camaro]

You already have a T/A, just build it bigger and badder. Sure those cars are bad ass, but why not just have something different, but just as bad? The LS1 is built pretty strong..and can handle alot. My vote goes to keeping your car, and really modding the hell out of it. But whatever you decide to do, good luck.

[Cronex]

I agree with 98camaro, keep the beast and mod it. How many other ones are you really going to see on the street?...not alot, at all...least not alot that are ACTUALLY Cobra's. So you lost one...and it screwed up your pride in your car. Get over it if you truely like the T/A. I can assure you, it will be a rare occurance. If you really are that upset, but want to keep the car, there is a shitload of mods you can do to put that guy in his place, so don't be loosing faith so easily.

[LS2 KLR]

Like most of you I'm out to kill cobras as well, except in a gt. For most of us normal racers we are at a huge disadvantage. For a small investment they will run 11s all day while it will take us a bit of change. If you want a go fast street car, they are hard to beat. I looked at buying one but ended up getting a motor for mine. Its always fun being thought of as the underdog.

[2-bowties&abird]

i would never get rid of my ws6 for a cobra. if i was you and did'nt want to mod the ls1, hell go out and get a ls2 gto. they have got to be giving those cobras a run for their money.

An LS2 GTO is alil on the heavy side and the mods are on the expensive side. My friend has one w/ a cam and he can't even get a rear for it, cause it has to come directly from Australia. :(

[adam3566]

Moser makes a 12 bolt I thought for them.... HM maybe I'll have to do some research on that one.

Will u come lay my Termi down

^ Since he is set up for the track you guys should go out and see the times on the twisties then do some 1/4 runs and post the results !

You want to be the third 03 notch on my belt do ya? A glutton for punishment. :bomb:

634 rwhp?? I would still run you, and prolly put your crap in the dust b/c you can't keep the tires from going up in smoke.

[Tracker9118]

Ill give you a run for your money have a 99 Z with a LS7 thats not stock.
1/4 in 11.42 at 124mph.:sword:

[rajiv1998]

again what do you want the cobra for? road, street, strip?

Basically, all i want is a solid 11 sec car that i can use as a DD. I agree, the cobra is the fastest way to get there, but the LS1 is cheaper. I guess i will wait and see, first i gotta sell my car before i think about anything else.

[Roastem]

Ill give you a run for your money have a 99 Z with a LS7 thats not stock.

An LS7 costs about 15 grand don't it? You would have been better off building a forged stroker with a massive blower.

Still, the LS7 would be my choice of N/A engine anyday.

I got mine out of a Z06 that was assended for $6600.00.

Listen i dont wanna sound like a ... but for every one mod a cobra does and LS1 will hafta do 3.

WRONG!!! i can trow on a SC and eat them alive... one mod...

[TrickStang37]

WRONG!!! i can trow on a SC and eat them alive... one mod...

really? one mod? i didnt know the injectors and fuel pump were capable on a stock LS1, let alone the tune. or the fuel rails. or the cooling system. guess that's a pretty stout stock clutch and rear end to boot! LS1's have quite a bit of overengineering apparently!

[LS2 KLR]

The old, "I can throw a sc on my lsx and blow away a cobra." Really man, wake up. Sure and lsx will outrun a cobra with less hp, but once you crank up the power to compete, you're on borrowed time.

[hoss 2000 z-28]

OP, just drive what you want to drive. These guys make good points but we aren't driving your car! You can make just about any car run 11's, it just takes $$$. I like the interriors of the Mustangs better personally but I like the lines and torque of an F-body so much more so that's what I bought after shopping both. I've seen guys go from a Mustang to a F-body and vice-versa, it's cool. As long as you drive American muscle it's all good. Post this same thread over on mustangforum and your feedback will be different, we are biased!

Good luck

STILL NEEDS THE TUNE!
You dont need injectors or a fuel pump,fuel rails, cooling system just reset temp when they come on.
But it needs the tune, you are wright some what. My shop has told me that if i do up the pump & injectors it may up it 5-20 more hp.
But wright now im still working with my shop to find out how much more i can get out b-4 i do that. wright now it at (451 rwhp) not fine tuned yet. I have a Z06 in the camaro in the pic, that is put out an ungod of (596rwhp) but after a trany/rear end went to hell still working on finding parts.

Yeah well Trollio, we have a factory blown LSX now in the new Blue Devil, lets see how the Ford gang handles that once they start "throwing pulleys" and "porting" superchargers. :boxing:

620 HP stock ring a bell? Forged components, hmmmm....

[BlankinSShip]

Why even give the Mudstains our time of day? Who cares if they are "faster"... They have been beaten down by the LS1 for year, and needed to redeem themselves. We still have raw engine, we still have bigger blocks (balls), and we still see more women driving Mustangs than men...

So lets not worry about the details, get back to this guys thread, and remember that LS1 is the best out there...

Cheers...

you can keep all the men and their balls if you want them that bad, I'll take the women and the win.


all that aside, you cant go wrong whichever you decide. If i didnt buy the cobra, i would have went LS1. but i cant see the stock fuel system holding up
on the fbody's. maybe they do, I dont know. i know even at my power level my fuel pump is at max duty cycle and the stock injectors are going to be done once im over 500rwhp.

Be sure to reread my post and then yours. Then hopefully you will realize what a moron you are. Chevy didn't just throw a sc on that engine, it was built for it just as the cobra motor. And yes it will be sick though I doubt I'll ever see one on the road.

And troll, can't say I've ever been accused of that. I was a member back in the day long before you (joe347r6). Ironically, I also own an ls2 vehicle but thanks.

Yeah I'm a little perplexed as to why people who don't even own or plan to own LS1's come in here. I used to own a 2001 GT w/ pretty much everything you could possibly do to it. Never once did I think, hey let me go onto another car forum and talk about how my car is superior.

[adam3566]

There is ALOT of guys actually doing it. Here are just a few I quick could think of off the top of my head, http://1320video.com/ryanfeatured.php, also http://dynosport.com/ scroll to the cobra section and theres 6 or 7 in the top ten alone that are turboed. Visit a few mustang forums and you'll see more turboed than blown cobra's.

[adam3566]

My '04 Cobra did 428 rwhp on a Dyno Jet with only a FIPK and JBA mufflers.

Big difference there too, N/A vs power adder, and lets compare power bands. I can guarantee the N/A is going to be a lot better than the boosted cobra. I will say some cobras do have a nasty power band but not all.

Well I've been outta the mustang loop for the past year but from my experience I'd have to say that cobra owners generally swap blowers, like the Kenne Bell or Whipple for the stock eaton blower. I know some guys do put turbos on but I'd say that it's not a large percentage.

[thopsramair]

The poor guy just needs to go get an 03 Cobra like the one that whipped him. Do a few mods to get it into the 11's like he wants. And then when he gets whipped in that car by a LS1 then he will post the same thing on his mustang forum. Soon after, he will be back in a LS1 so there is not much to argue about.

You can't deny the crazy potential the cobras have with stock motors. Even so, I'd much rather see it lose to an underdog such as an ls1 or gt. If it were me, I would install a 408 with a healthy cam and a shot of gas. Just as the whine of a kb/whipple cobra sounds sick, so does an na car with a nasty cam.

[TrickStang37]

the N/A car will not have a better powerband then a roots/screw powered cobra. full boost pretty much straight off idle. only takes about 100-200rpms.

http://i21.photobucket.com/albums/b259/bluelightning302/dynointernet.jpg

these numbers arent anything special, plenty of cars make that power and more from imports to old schools. but i dont know of many N/A cars that will have that powerband and area under the curve with only 450rwhp.

Currently my shortblock is at the shop but hoping to get it back by the end of next week. Had it freshened up and dropped the compression to 9:1. Then I'm hoping to hang with the "big boys." It made over 400 with 3lbs so hopefully it puts up some good numbers with around 17.

what makes me feel good is the fact that I have never lst to a ford mustang, other than my 66.


1999 Pontiac Firebird- 241hp
2000 Firebird Formula-330ish? hp (full bolt on car)
2002 Pontiac Firebird-200hp
2002 Z28 Camaro- Yet to dyno- (exhaust, lid, spray, cam,etc.)


99 would beat 99-04 Gts (unmodifed-slightly modified)
00 would beat 04-07 GTs (unmodified-modified)
02 bird' never races it's a DD
02 Z28 has only raced an 04 GT turbo'd and an 03 Cobra.

beat them both :cool:

oh my 99 did lose to my 1966 Mustang w/ a 289 bored over to idk... some crap.. I didn't know about cars then my 99 was stock and I was 16, lol

My only complain with the cobra's is that yes they do have a nice tourqe curve but peak hp doesnt come in to play until your just about ready to shift.

if you've been around dyno's you would know that the higher in the RPM you start the car off, the rwtq numbers come up consistantly higher. If he were to start off at about 2000 rpm, those rwtq numbers would not be as high. I bet it would still be impressive, but not quite what is shown there. and peak hp comes on at 6000rpm or so on mine, and the engine can rev out to 7000rpm if i really wanted to take it that high.



actually, and looking at the thread, you would see that the one that "puts my blower to shame" is actually running nitrous. a comparable 450 rwhp car, as I had said, would be this one:
http://i13.photobucket.com/albums/a299/ntimid8r/DynoJet11_19_05.jpg

impressive, yes, but the area under the curve/rwtq still goes to the roots/screw cobra. it doesnt even break 400rwtq till about 4600rpm whereas the cobra is there at about 2000rpm.

[GottaHaveLS1]

Automobiles depreciate the worst in value, and FYI cobras hold their value pretty well, much better than an LS1. I have yet to see a termi with about 50k miles go for anthing less than $20k.

Not true, I've seen some cobras with decent miles (can't remember exactly) for around 18k. Some ppl see ls1 f bodies with really low miles for around $30K and everyone says they aren't worth it cuz you can get a cobra and mod it for that price. But it's because low mile ls1 f bodies are appreciating in value. In general it's really a never ending battle. Too bad ls1 f bodies didn't come with a forged crank and a stout rear end... good bye cobras.

[GottaHaveLS1]

Another thing I forgot to mention:
Pullied Cobra: ~450 rwhp/tq 11 second car
H/C LS1: ~400 rwhp/tq 11 second car

I bought my T/A for $11k and if I was rich I would have spent $3k on a h/c swap and $3k on clutch/rear. and probably another grand on a tune and misc. boltons. = ~$18K total which is about the cheapest you can get a bone stock cobra.
I think its great to have less hp (spend less $) and still be equal or faster!

I think the crank is pretty good, but the rods (specifically the rod bolts) and pistons were the weakest part of the engine. Then again, it wasn't designed for forced induction either. I have been running mine at 475 some horsepower for a year now with no problems, but I think a blower would finish off the bottom end. :(

[TrickStang37]

Another thing I forgot to mention:
Pullied Cobra: ~450 rwhp/tq 11 second car
H/C LS1: ~400 rwhp/tq 11 second car

I bought my T/A for $11k and if I was rich I would have spent $3k on a h/c swap and $3k on clutch/rear. and probably another grand on a tune and misc. boltons. = ~$18K total which is about the cheapest you can get a bone stock cobra.
I think its great to have less hp (spend less $) and still be equal or faster!

when you start talking about total spent, then that brings on too many vehicles such as a fox body etc.


also, the difference needed by the cobra is closer to about ~35rwhp at that power level. about 15rwhp for aero, 20rwhp for weight.

475 at the crank or rwhp? When I was in high school, my math teacher, who had a 98 supra (and sold it to buy a c6 zo6), told me that forced induction wouldn't be the best route for my car unless i totally rebuilt the motor. He suggested nitrous. He said to start of with a 75 shot to get used to it and then a 100 would be fine.

I've heard from many people and companies that low boost on our cars will be fine. I think the 5 (maybe 8) psi kit from sts claims 508 hp or rwhp (not sure) on a stock ls1. If the ls1 can take a little boost, i have a feeling the clutch and rear would have to be upgraded as well.

Crank HP, and on a side note, if I see another mustang dyno sheet I am gonna :Puke: all over my boots.

[Getzen_Guy]

Don't get me wrong... cobras will haul ass, andare a pretty good pirce for what you're getting.

[third_shift|studios]

Listen i dont wanna sound like a ... but for every one mod a cobra does and LS1 will hafta do 3.

i dont' believe that. Mod for mod, an ls1 would kill a cobra. Aren't they blown 4.6L? So put nitrous or a blower on your 5.7 and bye bye cobra.

mod for mod, i dont think so. to be fair, add the same blower to the cobra that your adding to the LS1. the stock blower on the Cobra is pretty crappy compared to what can be had out there. there's a reason stock cobra blowers only sell for about $300.


and then eventually, it just turns into who can spend the most.

it is always a battle of money what we are trying to convey is that he could put 7k into his car and it would handle most of the bolton pullied cobras out there which would still be less then a modded cobra depending on what he bought his car for.

They aint that bad. My friend has an 03 with a stage 4 stiegemeier and is JUST shy of 500hp. No doubt a KB or whipple with the right mods and tune can make well over 600 to the wheels, but they are also not cheap.

That's true, i guess I was thinking of the newer and nicer cars cuz you could get a foxbody for a grand or less

[180ls1]

Have you considered a Grand National? they will not go down in value and respond to more boost with open arms. That was my origional choice but i can not afford one

[TrickStang37]

ok, I just noticed that graph i posted up there was of a procharged LS1. It took me quite a while but I finally found some 450rwhp NA LS1's. It was tough, most are in the 410-430rwhp range with heads/intake/cam + full bolt-ons. Here's a supercharged LS1 to compare with a H/I/C LS1 and a Pullied Cobra.

[Shoyoas]

but even i wouldn't trade in a car (ANY CAR) with a LS1. Not a camaro, bird, or vette. Just the same if i already had a Cobra i'd not trade it for a LS1. When you reached the level of ls1 or 03-04 cobra it's all about mods and drivers so switching to the other side because you lost a race is just silly imo.

Congratulations on finding the world's lowest HP procharged LS1.

Fortunately for you guys, on a stock bottom end, I like to keep them to 550rwhp for safety. Here is a procharged SS from a few weeks ago at 9-10psi. This car has a cam and fast90 intake and is the average of all stock bottomed SC'd cars I tune :

Another example is ClemsonDave's STOCK completely stock ls6 vette with 7 psi which put down 600rwhp and has run 10.62 at 131.

i didnt go out looking for a dyno of a supercharged LS1, your little buddy posted a link to a thread and that one was in there. He was talking about how the NA LS1 will have a better powerband than a SC Cobra making the same power. I clearly showed it didnt. The SC LS1 was completely stock + supercharger (the "throw a supercharger on an LS1 blah blah" excuse) and I just threw it in there as an extra comparison, it made decent numbers but nothing crazy. The numbers youre showing are basically combining the two LS1 arguments used. There are plenty of Cobras running much more power than that without even lifting the valve covers. And im sure there's plenty of high HP fbody's as well, but with much more work needed. you missed the point entirely.

and your "fortunate for you guys" should be aimed at your customers.

[Roastem]

With the same boost pressure, the LS1 is gonna make more power. End of story. Its all about the cubes.

Put 8# on an LS7, put 21# on a Cobra, and the LS7 will lay down more any day. Sad but :true: (cue Metallica)

Yeah? So show me a stock blowered Cobra that makes over 600 to the tires... Ever seen one run mid 10s with a manual tranny and 7psi? There are plenty of high 9 low 10 second stock-bottomed LSx cars right here in my city. There are also a plethora of modded cobras (again, right here) making as much or more that can't find their way out of low 11s to high 10s. Don't think because you got a forged bottom end from the factory that you are something special, you can be dealt with on factory pistons. For that matter, our local F-body club has several low 9-second full street cars, one of which is knocking on the 8-second door with his 9.05 @ 157 through full exhaust on 17" wheels and overdrive. Moving an hr north of here will find you plenty of high 8, low 9 second f-bodies that are regularly driven on pump gas and overdrive. There are no cobras anywhere near here that run like that and actually drive on the street. You can run into the cars I'm talking about on the regular.

The first 04 Cobra I killed, I ran 3 times on the highway. Met up with the owner and he was an excuse generator! He got onto the kick of talking about his KB blower and car and started talking smack like he had forgotten what just happened, so we ended up on the highway again. I went ahead and bumped my boost controller up to 18psi (from 15) and smacked him around again twice from 35-50 MPH rolling launches. The last time, as I let off in fourth, up by more than a few lengths, he went to 5th and stayed into it and flipped on his hazards like a Honda owner. A week later I ran into him at a gas station and denied knowing or racing me and wouldn't really look at me. I asked him if he wanted to try it out again and of course he had somewhere to be...... I have since had the pleasure of slapping 3 more around. I'll save you the digging on my car, H/C forged 347, 76mm turbo, meth... made 600rwhp at 10psi (makes about 25-28rwhp per psi) and it runs the street at about 17psi now. I'm sure you can do the math here. What kinda power do you guys make at 15-17psi again?

Those high 8 second/ low 9 second engines are not running on stock parts, either. There's a lot of money invested in them. Very few people really understand what it takes to run numbers like that. I do, and I'd put my 5.4L single turboed foxbody up against cars like that without a worry. It's not a dick-measuring contest....more like a $-measuring contest. So please, stop comparing high powered LS1/LS6 engines to the '03-04 cobra engines. We all know which is superior. What happens in the aftermarket only hinges on how far you're willing to go, and how far you can afford to go.

For Cobras to have the ability to run over 1000 rwhp on the stock internals is pretty damned impressive in my book (I've read about ones that have gone almost 1200 rwhp on stock internals. Can you imagine not having to build the engine? Just the fuel system, and the right turbo/turbos, and a tune. That's about the cheapest way to get it done in aftermarket modifications for any car out there with the slightly possible exception of a supra, and the highly probable (though more expensive to begin with) GT500.

I'm not worried about LS7s either. You can't really run back to them because they're weak when on the boost. We know it, and chevy knows it. However, I do look forward to Chevy's blown 6.2L ZR1 engine. Now that's going to be some factory performance.
