Hi, new to the forum and this is my first post. I own a 2002 Corvette, and usually have no problem handling anything I run into on the highway. I always tell my buddy that as long as I don't run into a Viper or a modded Cobra, I'll be OK. I have raced two stock '03/'04 Cobras, and by the time I hit 150mph both times they were well in my rear view. Anyway, on the way to work the other day, after 2 years of ownership and 0 losses, I finally ran into a modded Cobra. I have no way of telling waht exactly was done to it, but when I was doing 120 and he screamed past me I could definately tell it had headers/exhaust. So I'm probably sure he also had intake/chip as well. The guy didn't totally leave me behind, so he might not have modified the supercharger, but he also may have let off since he already had me beat.
Anyway, I managed to go 2 years spending minimal $$$ on mods, but after seeing/hearing the awesome sound and power of forced induction hand me my @$$, I have a serious case of mod fever and am planning to install a supercharger in a few months. What I am wondering is how much rwhp modded cobras with the stock blower ported/smaller pulleys generally make. I have heard that without paying for an aftermarket blower, porting the stock blower and doing all the bolt-ons generally peaks around 500 rwhp. Is this correct? I can install a blower only without changing anything else on my car and get to around 470-480 rwhp with conservative boost. Aerodynamics, weight, and gearing should make up for the rest at speeds between 100-160mph. I'm hoping not to have to go into the internals at this point.
Thanks for any info in advance. I'm hoping to get an '03/'04 Cobra withing the next year and a half as a daily driver, so I'll probably need some advice/help on modding it. Until then I'll be lurking. And if the owner of the maroon/dark red Cobra in Jax who flew by me earlier this week on 9A near Baymeadows Rd. is a member of this forum, congrats on a bad@$$, sweet sounding/looking ride. I was definately impressed, and If I ever get any free time between work and college, I'd like to take a closer look.
Must not be many fast cars out your way. Most pulley/bolt-on Cobra's run high 11's to bottom 12's. There is a few who've went quite a bit faster with the stock Eaton. But they're not putting down more hp. They're just lighter and every bit of their power down.
Most, with the stock Eaton, put down 460-480rwhp. That's with bolt-ons and a pulley swap.
If you get a power adder of any type, you won't have to worry about many stock Eaton Cobra's outrunning you.
I've wondered about this. I think it's just a freak coincidence that it hasn't happened before. I switched jobs 6 months ago, and now my daily commute has changed from not leaving my neighborhood to 35 minutes of mostly highway and 2 lane rd. driving, some I'm having a lot more fun lately.
Nice looking TransAm!
I just looked at SLP's site. Under $2,700 for around 500rwhp!!! Damn I wish upgrades for the'vette were that cheap.
As far as bolt-ons go, I have B&B Bullets Exhaust and Vortex Ram Air Intake. I'm going to add headers and maybe a ported throttle body or BBK 80mm TB. I want to avoid N02 b/c I want the extra power to be there all the time. I have a real addiction to speed and performance, and even when no one is around I like to open it up. That's the main reason I put up with the high $$$ of the 'vette. There's nothing like the rush of taking a broad curve at 100mph and sticking to the inside like glue. I definately respect Cobras and their power and ease of modification, and I hope to get one sometime in the near future. But it's still a car that is mainly a 6 cylinder passenger car in design, as far as height, weight, aerodynamics, suspension, handling etc. It would be cool if Ford would make performance oreinted changes to the body of the Cobras rather than mere styling subtleties. Oh well. Unforunately all of the American manufacturers are Dumb. In 20 years I could be driving a Toyota Corvette at the rate things are going.
The fastest recorded stock blower time is from a guy on svtperformance.com. He had all the bolt ons + I believe either a 50/60 shot of n20. 10.49@13x.xx.
Can't remember the exact mile or his dyno #'s but you'll get more info on that site.
You have an 02 stock vette and are beating everything around?Jees you need to come up here there are hondas that would be so far in front you wouldnt be able to see them!And I think you'll be surprised how good a 03/04 cobra handles,thats why they have IRS.

There are plenty of modded ricers around here that are quick from light to light. But once you get on the highway and play it's a different story. They just run out of power. I raced a modded, 12 1/2sec Eclipse with N02 on the highway once. He was on my tail until about 120mph. Then it just seemed like he hit a wall. With the weight, aero, and gearing of 'vettes, even in close to stock trim they can effortlessly reach 150-160mph.
Nice looking Saleen by the way!
What is the difference between a Saleen or Roush and a Cobra. Do Saleens/Roushs have changes to the engine's internals?
I love playing with Vettes, they are so much fun to beat up on, at least the ones who will actually race. I had 3 passengers on the freeway and effortlessly pulled away from one up until around 140 when I shut down. You must be facing stock Cobras all the time (which is hard to believe, they are so much fun to mod) because I have plenty of get up and go between 80 and 140 and only a 05 Viper pulled away from me at that speed.
But in any case, this message isn't to rip you (at least you said you were getting a Cobra soon), I love Vettes and the drivers are typically nicer since they are older drivers (however harder to find to race). If you really want to find out more info, someone already mentioned it, but the best place is svtperformance.com. There are guys running some sick cars there, in fact I feel slow after reading some of the posts...

id say thats pretty close, some can get up to 500. the stangs arent going to run you very well at 150mph, infact, not a lot of cars will. but 0-120, the modded w/ stock eaton cobra's are a hard car to beat. good luck in the future w/ the cobra!!! must be nice to have a 02 vette and 03/04 cobra sitting in the garage at the same time. are they hiring where you work?

I know how you feel. When I first got a 'vette, I didn't know much about cars. I had an '86 F150, and had no reason to go looking for internet car forums b/c I had no car/no $$$. When I first got a C5, I thought I was pretty damn fast. Then I discovered the world of moddding through online forums, and quickly realized just how slow my car was :(
In hindsight, I'm still happy with my purchase. It's a hell of a lot more expensive to mod than a Cobra, but I can be patient. In the meantime, it's an awesome car.

Oh yeah, nothing to be shy about with a Vette. Do you like the new body style? I'm kind of disappointed in the front end, don't really like the headlight look on a Vette, looks funny but I'm sure it will grow on me. I've got a buddy who's about to sell his C5 and get a '03 Z06 which has been modded to put down about 500 to the wheels. Now I'm gonna have to go out and get a Whipple to keep up.
I do like the new one, but not as much as the C5. My brother works at a Chevy Dealership that specializes in Corvettes, so I get to look at them a lot. The c6 does not take pictures well. It looks much better in person. It has some of the styling cues of the c5, but it also looks like a C4 in terms of size. It seems tiny next to the bloated C5. I definately the C5 Z06/FRC cars are the best looking. But I'll stick with my coupe. For the shocks and suspension parts to make the car handle just as good as a Z06, it's only $500 from GMPartsDirect. As for the extra power of the LS6 motor & drivetrain, that doesn't really matter if you plan on heavily modifying the corvette, which I hope to do. The Z06 guys will rail all day about how there is no comparison, but actaully the coupe is the better body style performance wise. At high speeds, it is much more stable with the fast-back design. That's why Lingenfelter used a coupe for their 427TT top speed run of 226mph.
Looks like I could get some good advice from all you in this thread. I just posted a new topic in SVT Talk. I am looking for opinions on the 03 Cobras. I am considering a purchase but haven't fuly decided so I wanted ot hear the pros and cons from a few owners. Thanks!
l really like the look of the new vette. thing looks mean.
Yeah, they aren't bad, but to be honest there is not much out there right now that interesdt me even in the slightest. It seems like companies are beefing up the power, but dressing down the exterior design. Examples include: GTO, Charger, Magnum, Durango. Dodge & GM need to hire new design teams to work on the exterior designs of their vehicles. Like a member on LS1Tech said ina recent thread, "About the only thing with a pulse now is Cadillac." To be honest, I agree with him. If I had to choose between a new Corvette or a Cadillac CTS-V, I think I may have to go with the Cadillac. I mean...there is only a few tenths of a second difference in speed and its a luxury car!
just the past two weeks, I've beat a Z06 vette, new GTO, Porshe 911, and a Grand National. no one else will stage up at a light except the little punks in Jap cars that think there car is the fastest in the world with that bolt on exhaust tip that make their car sound like a lawn mower. They rev up at light, I rev, light turns green, they shoot out squeeling tires, I just coast out. Tell them at next light they got me. Then I tell them I'll do it again for $$$. then it's like, well I have to be somewhere, or afraid of cops, etc.. Not saying mine is the fastest (cause it's not), but it is respectable in the area.
