I have owned my Cobalt SS for a good while now and I've never really been into modding it or anything until now. One of my best friends drives a Neon srt-4 though with the MoPar stage 3r and HOM and just a few bolt ons. He goes to the track occasionaly. I know his car is faster than mine right now but I Haven't raced him yet. He wants to race me though at the dragstrip. I was wondering what it would take to beat him. I am thinking stage 3 from chevy and exhaust, maybe a few other bolt ons. Please give me some advice here.

It would prolly tak a LOT more than just Stage 3 and exhaust... Unless you used the 50 shot option that comes w/ Stage 3. Someone who has more experience with the car might be able to help a lil more.

best case for you is stage 2 and exs, intake. look around to see what everyone else has.

maybe nitrous and stage 3 if you dont care for your warrenty.

He dynoed it out yesterday and his results were 373 foot lbs of torque and 356 hp at the wheels with just the stage 3 and downpipe. His torque curve was flat as a table too, if anything I think thats what would hurt me is that torque curve. Power shouldn't be a big deal though, just lots of boost.

Yeah... with him pushin over 400hp you are gonna have a TOUGH time beating him mw/ just boost. You will more than likely need internals and spray, and probably more than a 50 shot.

THAT, my friend, is going to be one hell of a mission.

Here you go, this might let you keep up with him:

60# injectors
2.5" pulley and ported blower OR turbo swap

P&P head
upgraded pistons
Meth injection
Dualpass aftercooler
Upgraded h/e ran in-line with stocker
header
DP
3" exhaust
50 shot

Either way you should look into upgrading your internals. As long as you need to do the pistons might as well throw some eagle h-beams or something in as well... but I would either go with a twin screw setup or a turbo. Both will require a fair amount of supporting mods to run safely, but the turbo will probably go alot further than the s/c if you feel like going further.

LMAO where did you get that impss thats gold!

Do they have procharger kits for these?

Um... i would trade the cobalt in on something else . If you have the money to make 400 wheel horsepower in a cobalt then go for it , you aren't going to be able to do it with the stock blower .

A turbo or twinscrew swap would be your best bet IMO. Over on .net, there are a couple of guys with 60#'s and 2.6 w/ the best tune they can get and are pushing just shy of 300hp. And you also have to consider cooling mods and meth and whatnot. If I were you, I would go turbo and get tuning down and then you will have him surprised. Some nitrous wont hurt either, lol.:cool:

I don't think you understand the seriousness of my scenario. I've got some deep pockets and I want to do this but I need guidance. I would prefer to do it with a super or pro because thats kind of the Cobalts claim to fame Is that possible?

Not gunna happen.. buy an srt and make it faster than his.. then you will beat him.

I've been looking into my options with the neon and I think thats what I'd have to do, Do you recomend going big wheel stage 3 or 50 trim to beat him? Although I still think it would be cool to beat him with a super instead of a turbo.

What is he running in the 1/4, would give us an idea of what u are up against.

I don't know yet, I joked with him about how I can beat him stock, since hes on worn out street tires and does nothing but spin. I'll give you an update when he gets some form of traction and the drag strip opens up again. Can I get that kind of power out of a cobalt without a turbo swap?

Obviously you need boost to acomplish your goal, there are as everyone knows 3 kinds, turbo, supercharger, nitrous. You don't want turbo and I don't know of any superchargers for ecotec that can put down enough psi to equal or surpass a SRT-4, so nitrous, just don't blow your engine. Upgrade your supercharger stuff with stage kids from GM or whoever the heck makes them. Once you've maxed that out, if you need more, put on a small nitrous kit. Unless you have a 1/4 time from your friend you won't know if you can beat him until the duel day. Turbos are just too damn good compared to a small supercharger.

Aren't there larger higher flowing superchargers that can be swapped on?

I think a Centrifugal Supercharger would be the way to go. I'm guessing there is little or no aftermarket support for that?

For those Cobalts that are in the 11's what pathway have they taken?

Have you ever read the GM Performance manual that shows different steps to get a cobalt to high horsepower. I believe they use turbo eventually, even then they still tear apart the engine to strengthen it and put it different pistons. The SRT-4 has insanely low compression so it can take the 14 psi of boost, effectively doubling the natural amount of air that would be in an engine that size. I don't even think the stock cobalt engine can take 14 psi but you'd have to consult an expert that you might not find on this board. To be honest the cobalt forums have been dead lately. 2 active threads a day... OUCH, the local mustang club has more posts a day than a national cobalt forums. Maybe everyone is on the other cobalt forums??? Basically you have to put down lots of time and money if you really want this done. As for centrifical superchargers, they might get you to boost you need but you might have to make custom mounts for them and good luck with the belts. They are also really expensive, I almost Procharged my mustang but then I said screw it and bought a V8 chevrolet.

Time and moneys okay. How strong is this block?

:lol: That's funny, the stage 2 kits puts you at 15psi. My setup is at 19-20 psi depending on weather. Read my first reply, that tells you what you need. A turbo, nitrous, or a more effecient blower (Eaton TVS which is being released this spring) to beat him.

Would that have the potential to make that kind of power? Eaton TVS

At .net there is a guy with a turbo swap running over 20 psi on stock internals .

Well that answers that. Turbo it until you win or blow up.
