I was wondering what it would take to be able to take on some 03-04cobras and the new Z06's theres a couple of them calling me out. I know I cant take them stock, all i have is a lid. So what would i need to be able to run with these or beat them?

heads, cam all bolt ons, and forced induction like nos, s/c or turbo.. i would like to also know what kind of setup will it take to run with 2003-04 cobras on the street also..

My buddy has traped 119mph in the 1/4 mile with basic bolt ons on his 03 cobra.

anyone else have some imput? Im trying to figure out what i need to do.

I'll take a shot at all 3 questions. TXZ28LS1: Heads, cam, bolt ons, and forced induction??? Are you telling me it takes all this to keep up with a cobra? Are you high? I've heard/read of camaros with just a lid and catback being able to run with some cobras. PLucas: 03-04 Cobras can gain alot of power with your basic bolt ons. Trapping 119 is right on par with what I've seen them do at the track. Also I believe that most cobras dyno around 360-370 hp to the wheels (stock). For any camaro it would take a full exhaust, intake, and a tune to reach those numbers.

The Butcher

Well, ssmaro my buddy (ba98ta) and I were out pony-pounding the other night and met up with a guy who had an 03 cobra. We raced him from about a 30mph roll and pulled on him. Not like an *** whooping but thing is the trans am is an auto, and the cobra was downshifted ready to roll. The trans am just had a lid, exhuast, and a k&n at the time. I have heard 360 at the crank stock, but I don't believe they make even 300 to the ground. As far as your list of mods TXz28LS1, seems a bit much don't ya think?

cobras are underrated from the factory. a good healthy cobra will put down around 370. to keep up/beat one you need all the typical bolt ons with heads/cam or some other route like N2O or FI

00454sscamaro

the cobras not the faster of the ones he mentioned though , ive seen vidoes of some nasty camaro's get there *** handed to them by the new z06. dont know exactly what it would take but, youd hafto have alot of hp(guessing atleast 500rwhp on a street matchup) in the quarter you could probly be pretty shy of the 500 mark if you had better start, grip, gears- etc.

300bhp/ton

Ok, I'll try and answer some of these questions as well as correct some of the miss-information already given in this thread.

1. A stock Fbody makes about 320-350bhp SAE Net, depending on year and model. This means ~300rwhp SAE on a Mustang Dyno for M6 cars and ~280rwhp for auto's. Higher dyno numbers are from Dynojets which dervie HP differently and don't compsre easily to SAE Net numbers, the really high dyno numbers are also not corrected so are pretty pointless for comparison sake.

2. The Terminator is not really underatted, at least by no more than 10HP. A Typical 03/4 Dyno corrected to SAE on a Mustang Dyno is 340-355rwhp. Any higher numbers are again from Dynojets and not corrected. So the 370rwhp cars are still only making in the region of 390-400bhp SAE Net.

3. You will not get a Fbody to produce 360-370rwhp with a full exhaust and tune. In fact with ALL the bolt on's you will be lucky to see 360rwhp even on a Dynojet and 340-350rwhp on a Mustang Dyno corrected to SAE.

4. Performance:

Stock vehicles, assuming a competent driver.

A4 Fbody 13.2-13.7 @ 102-106mph
M6 Fbody 12.9-13.2 @ 106-109mph
Terminator 12.6-13.1 @ 111-112mph
C5 Z06 11.9-12.5 @ 115-118mph
C6 Z06 high 10's/low 11's @ 122-126mph

5. What are the cars you intend to race?

Are they modified?

Which "modern Z06" do you mean, C5 or C6?

Also is your car auto or manual?

7. What type of racing?

1/8th
1/4
roll racing
stop light to stop light
from a dig
at a track
on the street

8. To stand a chance of winning you need to have as good power to weight and some means of deploying it. From then on its all down to the driver.

If your an auto, or a good driver, then going from a dig is an advantage. As many people can't launch very well. Cobra's are notorious for wheel hop in standard trim, so out of the hole they can be a handful. Use this to your advantage.

9. How much money do you want to spend?

An easy HP upgrade is nitrous. A 150 shot will automatically give you more than enough to handle even lightly modded Cobra's and you might even scare a C6 Z06, although they will still have a hefty weight advantage.

Normal mods go along the lines of induction and exhaust mods. These allow the motor to breath better and produce more HP. From here on you are looking at cam only or h/c setups. There are some wild cams and in a M6 car can see as good as 430rwhp on a Dynojet (400-410rwhp on a Mustang Dyno). This is usually enough to play ball with quite a few cars out there.

h/c setups can generally see 440-480rwhp on a Dynojet with all the bolt ons. An auto tranny car will dyno less but the engine is still just as powerful.

You can add nitrous onto an cam only or h/c setup and run at 500-600rwhp. This should be quite a good street setup. But remember nitrous is not operational all of the time.

The next step up is larger displacement motors and FI (super or turbocharging). But it gets very expensive very quickly. An FI setup can deliver 500-550rwhp on stock internals as a rule. If you want more HP then a built motor is required. 600, 700 and even 900rwhp are all then possible.

To deploy the power you'll need to upgrade the rest of the car, this even applies for cam only setups making 400+rwhp.

Better brakes are a must for street racing. Different final drive ratio is required for a cam usually. Auto's will want a stall. Then there are chassis/suspension upgrades like subframe connectors and lower control arms.

If you're serious about racing from a dig then a bodt mounted torque arm would work wonders along with some sticky tyres such as MT drag radials. These however might brake your rear end, so a new rear like a 12 bolt or 9" would be sensible.

To get an ultimate setup cost a lot of time and money.

However a pretty badass setup can be had for sensible outlay, you just have to be realistic on your goals and aims.

Hope this helps

The only thing I see that looks off is the C5 Z06 1/4 mile estimate...seems pretty optimistic.

4. Performance:

Stock vehicles, assuming a competent driver.

M6 Fbody 12.9-13.2 @ 106-109mph
Terminator 12.6-13.1 @ 111-112mph
C5 Z06 11.9-12.5 @ 115-118mph
C6 Z06 high 10's/low 11's @ 122-126mph

ya a full bolt on trans am should beat a stock 03/04 cobra. but to beat a new z06 will be tough very tough i would say full bolt ons with the heads and cam and some NOS to help. i would say maybe a 150 shot.

300bhp/ton

Low 12's should be quite acceptable on a good day with a good driver in a stock 02+ C5 Z06. The 11.9 @ 118mph was from a magazine test, but I think it was done off a 2.1 60' or something stupid. I have the article somewhere. But there's several guys who have duplicated it and I think a few who have gone faster.

However when are things ever equal, so yeah I bet there's plenty in the mid/high 12's.

Hmmmm, so would I be able to hang with a Cobra?

Mods are in my sig, and I have 410's also(car was dynotuned...putting down 349 HP and 357 ft/lbs of torque) ...I think if I ever run into a stock cobra it would be a solid race

300bhp/ton

In theory it would be a drivers race against a stock 03/4 Cobra. But it would be advantage Cobra, because they still have a HP advantage.

I bet that your 349rwhp was from a Dynojet. Which means it would be nearer 326rwhp on a Mustang Dyno. A stock Terminator should be making 340-350rwhp on a Mustang Dyno.

But remember racing is an odd ball thiing, espcially from a dig. I mean, how many times have you just wheel spun a little too much, let the car bog down or been a little slow on shifting?

Most people most of the time do not achieve the cars potential when racing. And probably more often on the street. I mean if you wheel spin a little too much back off then get back on the throttle you can easily loose a second. So your potentailly high 12 second car will probably achieve a low 14 second run. Although the trap speed should remain more constant.

Roll racing is much more about who has the more powerful and faster car.

So to look at it another way, assuming an "average Jo Public" driver. You may be able to win 3-4 out of every 10 races against a stock Terminator.

300bhp/ton

Here's the artical: http://www.gmhightechperformance.com...vette_feature/

It was a 1.90 60' and 11.97 1/4, stil not bad for a stock C5 Z06

Allow me to be blunt...

Your fucked!

All you have is a lid? You could slap on a turbo kit with a T-76 and still not have
enough to beat a new Z06 or a modded Cobra.

Im just goin to throw in my knowledge here, I was with my buddy when we dynoed his 03 cobra, it made 417hp and 411tq all he had was k&n intake, magnaflow exh and running with the devil tune, and that car smoked the **** out of me on our way home and I had lid,k&n,slp loumouth,slp maf,Free ram air mods, short throw, however my car only dynoed at 280hp at the time, now hes got ax x-pipe, and few other things, even with my new found power in my sig im still not expecting to beat him.

People say a 350hp f-body can keep up with a 390-400hp cobra just cause of the weight difference.

Heads/cam/bolt ons can put you in the 430+rwhp range. If that doesn't do it, a little 100shot of squeeze on top will do it for sure...ask me how I know.

Damn unit, you are going to make the poor kid cry lol. although you are right.
