Hi guys, I just bought a cobalt SS 2.4l with an automatic transmission. I want to do at least 15.5 on the 1/4 mile and I don't want to break my warranty. Can someone tells me the parts I can put on it and it'll not break any warranty.I know that GMPP don't break the warranty. Can you give me the adress of the site please(gmpp). Tanks.

there you go ;)

intake/tune and you're golden.

buy GMPP CAI and exhaust, drop weight out of the car and run low 15's

Even if my car is auto?

well you should run sub 15.5. I'd hope. Go look at the Offical 1/4 mile thread to see times and mods

yesterday at maple there was an auto 2.4 ss and it ran 15.7s

our auto is not THAT slow ;), pretty frisky with a tune actually

forgot about B&M shiftplus.

That's the cheapest easiet mod on Earth for the Auto guys.

Can you give me a link where I can buy one because on the B&M site it doesn't work...!

Tanks !

if your looking to keep your warranty the b$m is not the way to go.

search buddy.. dont be lazy

my best with an auto, full bolt-ons, and a tune was 15.2

that's crazy. I can't believe the auto does that much. I'm hoping to be below 15.5 in my LS with fully bolted and a tune. Possibly low 15's if i can figure out how to launch.

I ran a 15.8 stock.

my best with an auto, full bolt-ons, and a tune was 15.2

thats pretty good

15.8 stock...How did you did that? It is supposed to ran 16.2(automatic)

And I know for the B&M but when I'll go to the garage can I removed it and i'll not appear?

there was a 2.4 balt that I tuned with full bolt on's. He ran a 15.1

the tune is going to be the biggest help, and you can really feel it on the auto's.

15.8 stock...How did you did that? It is supposed to ran 16.2(automatic)

And I know for the B&M but when I'll go to the garage can I removed it and i'll not appear?

:lol: no!!! where the hell did you get those numbers? lol like i said i saw it for my own eyes yesterday ran at 15.78 stock

Damm! that's pretty good numbers! Glad to know that my SS auto do 15.8 on the 1/4 mile! :) it's time to put some money in it! I think i'll begin with I/E/T and after 2 years maybe hahn turbo kit!! :)

yeah and im proud to say i finally got a 2.30 60 foot lol on them damn pirellis

stock i went to englishtown and ran 15.7..track prep blew..it was 30* out..my 60' was 2.28, cant wait for the track this summer with full bolt ons and a tune..hopin for low 15s if not high 14's..ill be happy

when you say full bolt ons...what bolt ons do you have?

injen intake, ca header, ca downpipe, gmpp exhaust, upgraded injectors(ss/sc), permacooled trans cooler, and hp tuned

yo illmatic i still have the ss/sc injectors in my trunk? im not sure if its safe to put them on

best is to get a base tune to work off and u can see if u need them just yet..

yo illmatic i still have the ss/sc injectors in my trunk? im not sure if its safe to put them onLog you car the way it sits now. See what the IDC's are and play with the stock tune to try and bring them down. If you still think you need the larger injectors (IMO you dont) You will need to tune for them!

Ask questions if you need help thats why the forum is here.

or pm me..hahaha.

stock i went to englishtown and ran 15.7..track prep blew..it was 30* out..my 60' was 2.28, cant wait for the track this summer with full bolt ons and a tune..hopin for low 15s if not high 14's..ill be happy

So do you think once I get my typhoon intake installed on my auto g5 gt i'll be able to run about 15.6 or so?

its possible..

take your seats out and what not

u can def run that time..if i can run stock 15.7..u can run that...i wish the track was nice that day..but ive got summer to see how this thing runs.

im curious what i can do if i get a good as tune with my mods..but i never been to track before so i prob wouldn't react fast enough

Were all headed to the track in a few weeks so I'll let you know how I run...

if u get a good launch anything can happen..i mean my tune is solid. it opened the car up a lot

im curious what i can do if i get a good as tune with my mods..but i never been to track before so i prob wouldn't react fast enough

Your reaction time will have no effect on your time. The time clock starts when you break the beam, not when the green light turns on.

im curious what i can do if i get a good as tune with my mods..but i never been to track before so i prob wouldn't react fast enough

yeah come with my jimmy next time.. i can run your car for you.. ive been racing since i was 14.. at high school drag i was running .02 reaction times with 2.1-2.2 60's :twothumbs

yeah come with my jimmy next time.. i can run your car for you.. ive been racing since i was 14.. at high school drag i was running .02 reaction times with 2.1-2.2 60's :twothumbs

Good luck pulling a 2.2 60 ft
I cant pull one for the life of me lol

you DO NOT need the SS/SC injectors, unless you are going turbo/supercharged...I've been told that on here many times and by a few mechanics...lol

full bolt-ons and a tune are you're all set...maybe even without a tune, you'll be there.

yeah and im proud to say i finally got a 2.30 60 foot lol on them damn pirellis

how the hell do you do that, I always get 2.5

Let off the gas a little... lol! Our stock tires aren't the best for the track either, I can't wait til I wear mine out so I can get summer tires.

Good luck pulling a 2.2 60 ft
I cant pull one for the life of me lol

lol umm i have.. i just said i did lol i have 8 slips to prove it haha

how the hell do you do that, I always get 2.5

i had brand new pirellis.. 3 days old.. (i dunno if that makes a huge difference) i had one hell of a warm up burn out.. yankeed the ebreak did a burn out for a good 5 seconds until i saw smoke from my wheels above my hood slowly let it out and kept it goin to the tires got sticky.. deep staged launched at 1,500 rpms pedalled the clutch( first day i tried this first 2 times didnt work to well i dumped the clutch but got used to it) and then when i picked up my slip i had one of these :-D:#one::twothumbs

but mine is manual.. not auto..

if ur gonna keep it in "D"..rev it up to around 1500-1800..hold that brake down..light turns go for it.

if ur gonna keep it in "D"..rev it up to around 1500-1800..hold that brake down..light turns go for it.

well u want ur TC off for a decent lauch... put it in L or add a TC switch... and u can go all the way to 2500RPM rite before green then let the brake go.

yeah t/c off in my car..haha bad idea at the track..wheelhops too much.

nooo if you have t/c on.. your car will go slower because the moment your car spins it bogs your engine down.. my boy in his 350Z ran a 14.3 without traction control and a 14.9 with it.. take it off just learn to ease of the gas.. racing isnt just who smashed the gas to the floor the fastest

QFT! heres how i launch, rite before green i go ALL THE WAY to 2500, it wont hurt ur car, thts the max it can go. then just ease off a bit to get traction. then practice over and over and over again lol

i can leave mine in drive with no t/c thanks to my tuner

well hmm so can i..hahahah..if i really wanted to..LOL

Virtually every performance mod (bolt on) will NOT void your warranty. However a turbokit/supercharger/nos will as they add additional load to your engine.

But exhaust, header, intake, downpipe will be just fine..regardless the company (doesnt have to be GMPP)

Are you sure ''Turbo06sedan''? because everybody here said that it WILL void your warranty...

it will not void your warranty unless they can prove that whatever broke was because of your mod

lol umm i have.. i just said i did lol i have 8 slips to prove it haha
I was not saying it is not possable, Im just saying that I cant pull a 2.2 60 ft

I gots the Injen CAI and I had a MAF sensor go bad and they said no warranty.

I was not saying it is not possable, Im just saying that I cant pull a 2.2 60 ft

And I'm trying to get some money up for a tune sometime this summer...waiting for that incentive check. :cssNET:

A buddy of mine had the same problem. So IMO just keep it stock or if you really feel the need to mod you car use GMPP and have the dealership install them for you so if a problem should occur there won't be any issues with the warranty. :)

DO NOT DO THAT^^^^^^^^^^^^^^^^^^^ :nono: you will pay pretty much double.. which wont get you anywhere because if that part goes back u could have fixed it for half the price anyways..

let me know when your ready, and I'll buy the credits.

i ran a 15.5 this year with my mods in my sig.

With alittle more tuning I hope to be at 15.1

i want to get down to the track soon...hoping for low 15 and or breaking into the 14's. when i was stock my 60' was 2.2...just after that there was not much power..not that my car is fully modded with bolt ons and tune..i want to get it there..and ill be happy

Is it possible to hit the 14.9 with full bolt ons and a good tune?

i dunno..im hoping too

Remove weight from the car and do it.

Is it possible to hit the 14.9 with full bolt ons and a good tune?

it hasnt been done.. the fastest was 15.1... and that was actually with a 4 door 2.4

me and my buddies have ran 15.2

A tune alone will get you the 15.5 that you want. I tuned a sedan with intake headers and exhaust for 15.1

As I said before, has anyone dropped the 150lbs out of their car and tried it.

Spare jack and other seats.

alright tanks alot guys!

As I said before, has anyone dropped the 150lbs out of their car and tried it.

Spare jack and other seats.

i have and ran a 15.2 but i just have intake and exhuast

so fourteens are pretty easy. Fully bolted, tune and weight reduction will put even an auto into that range.

So that puts my 2.2 in the low 15 range with the same setup and a manual.

Is it possible to hit the 14.9 with full bolt ons and a good tune?

Yes it is. Flytrap another modded and tuned 2.4 ran a 14.9

Here is a link to his garage, where you can see his 1/4 mile passes anda pic of the time slip

ill let u guys know how i do when i get to the track this summer when its nice out

lol u guys dont get it.. with faster more hp cars.. its easier to run 1/4 times with auto..

Says he's running spray, so was it timed with the spray or no?

I got a 2.29 60ft. on my 2.4 auto

Says he's running spray, so was it timed with the spray or no?
Yep his 14.9 was before the bottle was installed.

Yep his 14.9 was before the bottle was installed.

yeah but he has more mods goin on than just your standard bolt ons..

Well see tomorrow night what times I get, k&n sri +b&m shiftplus. Haven't been to a track but should be fun.

Yep his 14.9 was before the bottle was installed.

Ok, just wondering. And like fbaero said, what other mods? Like internal mods?

nah bro...i think if u have a good driver with a good launch with full bolt ons..its possible...rite!?!

Should, I've had some awesome launches in my car and stomped some faster cars, then again some bad one's and my car just takes a shit and makes me look bad.

It's been done with just bolt on's, so I would have to say yes it is possable :lol:

it's nice to know:guns:

so i cant wait till i get to the trackthen

so i cant wait till i get to the trackthen

You and me both, I'm going next Friday so I can get some numbers with my mods then I will be talking with Mike (REDFOCZ) about a tune, then run it again and compare.

Gah, first and best was 16.09@88.10mph. Mind you the elevation here is 2200ft, so I'm guessing that would make some difference.

plus, you have the canada mod, in florida, even at sea level, you can basically plan on adding a half second to your times.

Man...that's *&^%^$ Up! I just get owned by my friend's cavalier 2001 Z22 :S

I need to put some money in my slowbalt hehe!! :P

u def got ownd...moddin time foru..lol

never tought that a freaking cavalier would stomp me :S

how in the hell did you lose to a 2.2l Cavalier??? I used to have one of those and they were slow as hell!!!

my stock 2.4 beat a fully modded 2.2 by bus lengths.

my stock 2.4 beat a fully modded 2.2 by bus lengths.

I call BS

I walk all over stock 2.4s

i dunno, it's hard to say. if it's just a 2.2 with an intake and exhaust kit, yeah, i don't think it would be close to a 2.4. my 2.4 can get down when she's in a good mood, lol.

^^^ i agree

stock 2.4s are in the low 15s we have slips to prove it.

umm ask any of my LI guys...it was a 05 2.2 with intake full exhaust, body kit, lowered...he used to chill wit us..we went from a dig..had like 4 cars on him..roll pulled real good on him...

I've beaten my friends 2.4 on many ocations.

Just because my car has "only" and intake and exhaust doesn't mean thats the only thing thats making power. you forgot the piggy back ecu I have as well as the fact that I'm ligher than you by at least 100lbs.

Yeah I walk all over 2.4s

Theres one of the reasons it's slow.

Body kits add weight and massive drag.

i'm not saying that you're not faster than i am. my point is, every car is alittle different. for example, i've left SC's looking at my round tail lights, but that doesn't mean that i "walk all over SC's"

yeah ive pulled on my friends stock 05 ss/sc..am i saying i can beat them all..hell no..can i beat my good friend paul turbo 2.0 pushin over 400whp..im sayin a 2.4 cobalt shud def beat a 2.2 cavi...the 2.2 ecotec in the cobalt is a better motor than the cav..i can tell u stock vs stock.. 2.4 will beat a 2.2....i used to own a 2.2 until some dude hit me at 70mph in a 30(long story)..it will be a close race..but modded vs modded..2.4 will win if they can drive.

i'm not saying that you're not faster than i am. my point is, every car is alittle different. for example, i've left SC's looking at my round tail lights, but that doesn't mean that i "walk all over SC's"

I did say stock 2.4's

Modded one's beat me of course.

Only when they are stock will I beat them. Thats all :)

this is true..ur are quite modded as i can see in the sig..hows that intake manifold going for u? ur auto im guessin..wut does that thing run the 1/4mile in

My last attempt at the strip was 15.9 at 89 mph.

That was before the 2.4 intake and header and dp though.

I dunno where I'm at now but I will say that on a dry day if I leave it in first (auto) and stop on it when I'm around 4500rpm I am at the limit of traction for my tires, they will start to break loose.

Yes I lost VS a 2.2 ecotec. I'm stock and he's stock. He was manual and and i'm auto. we start from 20 km/h and went to 100 km/h. I know that he was a little bit in front of me in the end of his second gear. My car is very slow when I floor at 20km/h. He have a BIGGGG lag. That sucks!

I've searched on www.dragtimes.com and all Auto coby 2.4 are in the low 16 or high 15 and I thing stock cavalier 2001 2.2 are doing 15.9.

my best time stock was 15.7 this was 35* at nite in good ol englishtown, nj...track prep sucked too..lol

sorry but you wouldn't take me at least :twothumbs but was the 2.4 you were racing an auto? then sure it would be a good race. or the guy can't really drive all that well, or you drive that well and can get every bit of speed out of it. but either way cobalts FTW and just for the record i am not call you BSer or what not.

Yep he was auto and had a Rebel Auto Works CAI installed. Other than that he was stock.

It was a good race.

I bet I would be in mid 15 second range with my latest mods. With traction of course, because thats now becomming a concern with my crappy 205's

yeah i wouldn't doubt you being able to high mid 15s yeah grab some new tires and start getting on my bumper :thumb:

new tires will def help..those pirelli's blow

new tires will def help..those pirelli's blow

i always thought they were an okay tire. def better than most stock rubber on cars of the cobalts class.

that said, when mine wore out, i purchased Sumitomo HTR Z tires from tirerack. so far, for $55 a pop, they outgrip the stock pirellis by a wide margin and don't break loose nearly as easily.

alright! Injen CAI and B&M shiftplus on the way:cool:

Maybe not by todays standards and compared to the SS/SC but these 2.4s are pretty quick. In the mid to high 15s we are faster than my old 88 Monte Carlo SS with a 305, and that was considered somewhat quick at the time at 15.9 in the quarter, and faster than my 89 Z24 with a 2.8 V6 which i thought was fast as hell at the time compared to what else was on the road back then.

My feeling is, is it a hot rod like an SS/SC? no but the 2.4 is pretty neat in its own right, for what it is.

oh yeah, a mid 15 is better than 90% of the muscle cars ever made

Yeah isn't that funny its amazing what they can do with a little four banger now. Could use a little more torque but with the gas going up im very happy with this car, its a pretty good compromise in every way. Its quick, handles great, good brakes, decent ride, good mpg, looks good, decent factory stereo, best car I've ever had at any price.
