ok guys was on ************* and no one knows anything there but then again it took a week for me to post but its in the past

ok picked up a 07 ss/sc cobalt with 43000 miles for 7550 clean tittle too honestly its alot slower then i thought it would be however all these youtube vids are showing it stomping the crap out of former asain tuners ive had with just stage 2. i have 4 friends and i have always had the fastest car but now my friend got a pos 98 mustang gt and it beats me. so i was wondering wat all to do to upgrade it. the gt only has prolly 240hp/310tq

now i got TONS OF QUESTIONS THAT I CANT FIND ANSWERS TOO SO HERE GOES

ok i am looking at custom stages and maybe an intense pcm so i dont have to get it tuned and i can install everything my self

whats the safest pulley size that doesnt need a heat exchanger and what injectors to run

does the gm smaller belt work for all smaller pulleys?

is a heat exchanger hard to install and or manage

is there really a lot of difference between 2.7 to 2.9 or 3.0



problems im having with the car currently

getting really poor gas when supercharger is being used like 15-16

also my check engine light is on cause i dont have a cat how can i shut it off for good

got 2.5 full megan exhaust and it sounds really fart cany

my exhaust rattles pretty bad i dont know what to do about it

i got a cold air intake and the maf is really close the the intake filter and it is messing up my take off i think

also when i launch it i get a lot of tire spin which is what craps my launchs at instense there is a 50% reduced boost in first to get a good launch is that worth it?



ummm im prolly missing something but its 1am and im eating cheese yum yum

thanks for your answers guys hoping people here know something

well first off i didnt read the whole thing but i can awnser a couple question.
first with the gas mileage thats normal .

for a stage kit i would recommend ott's stage one its a 2.8 and it comes with 60's i would also recommend a few cooling mods
the gm stage 2 belt works up to a 2.8 pulley.

the cel if i remeber right you can tune out with hp tuners

ottp stage 1 > all. Intense pcms SUCK, you WILL blow your motor on there pcm's.

ShortStack

Do not use intense.. please... Because then we will have to post explaining what a blown engine sounds like later on down the road for you.

I used a 2.8 pulley with no h/e... **** there was someone who ran the 2.5 with no heat exchanger... The GM belt will work down to a 2.7 or so... although some people have trouble running the stage 2 pulley... which is just weird..

Winkdogydog101

how do you install a heat exchanger i think if i knew how that would elminate some of my fears of cooling mods is the heat exchanger all i need? for a 2.8 pulley and i hear there isnt a great difference from 2.8 2.9 and 3.0

looking at the ottp stages cant find info or their home page i hear good things? any bad? better then intesnse

its just ottperformance.com

Winkdogydog101

i dont see where to get pcm tuned on that website the pcm is kinda my biggest concern and that it runs flawlessly

well first off. if you can get a custom dyno tune, or street tune....do that.


http://www.ottperformance.com/Cobalt...duct_info.html
theres the link for the tune. but like i said. if you can get a custom dyno tune or street tune. do that first. mail in tune should be your last option.

Winkdogydog101

ok really looking for a good tuner for pcm is it worth private tuned? or is it better just to get a canned one now intense isnt saying canned ott is i dont really like the way the describe it cause oii is also running 60lbs

is 60lbs better then 42's i know there is more fuel but with the pcm tune will 60s run as smoth as 42's with just a 2.9 or stage 2 pulley? also whats the going rate on some 60's

also i have 225/40 and 245/45 and i wanted to put the 245's in the front do you think the width will rub? has anyone done this also the meat of the tire is a little more will that throw off the car at all really want to know if that will give me a bit better launch and speed gains

also as a add thank your exsoccer you have been helping me out a ton

Dr.Balt407

just get the ott stage 1 and there h/e and get your exhaust fixed and you will fall in love i got my car november 08 and im still learning about these cars but i chill with a good group of guys and i try to learn as much as possible.... now if you need answers (which we are all giving you) call josh from ottp (number is on the website) he will tell you exactly what you need to do.... look at my signature, get that all your complaints are GONE!

Winkdogydog101

well hows it working for you whats your track time? and did you do the install your self? also it isnt just 350 its more like 500 for all the stuff i want i just wanted there pcm but maybe but i like finding good deals and saving money

also is there somewhere that shows how to install a heat exchanger

also how much hp does ott stage 1 add its like everyone elses stage 3-4 i find that funny

ShortStack

Intense is still a canned tune...

60s will give you more head room to work with if you decide to add more power... They do not Add power themselves, they just allow you to make more power... get the 60s...

The idle can be funny when u start using larger injectors.. nothing unbearable though..

And for your cars sake, dont use intense.

daythecountrydied21

as said before. intense = no. responsible for the majority of pop pops.
ottp if you're going canned for sure.

rnjmur

Getting a custom tune will always be better than a canned tune.

The size of the injectors won't make any difference on idle or driveablility as long as the car is tuned for them. If you are going smaller than a 2.9 pulley you will probably need 60s.

245 width tires will rub when turning, not to mention 245/45 will be way too tall and you will bottom out. Some people have gone as big as a 235/40 and even they will rub occasionally.



7550 for an 07 is pretty cheap... how did you manage to get it as such a low price?

A 98 Mustang GT against a stock cobalt should be pretty close. From a dig the mustang would probably jump you, but from a roll it would probably be a driver's race. I never ran one stock, I did run a 98 GT when I was just stage 2 from a dig and took him by about 6 car lengths, maybe more.

rcorona8

same here, i have a GM stage 2 with 2.9 pulley! but i really want to go down to 2.7. what extras do i need for this setup to work, besides larger injectors and cooling mods?

daythecountrydied21

lol stock 98 gt vs stock balt should be balt by a few cars, gms2 should be even more.
they're hogs until recently now it's about even with the stang edging out your basic stock or st2 car..

Dr.Balt407

Man the ole' saying is YOU GOTTA PAY TO PLAY The ottp stage kit is running good and its reliable (since i dont have a wideband or intercepter) untill you get a wideband and a intercepter its the best route for you because without those two things you dont want anyone to custome tune your car.... do expect mid to high 13's at the track depending on driver....

Winkdogydog101

well we dont have really got tune shops we have them but there not that great and i really dont want to drive down to phoneix for a tune and im pretty good when i know what to do i had no idea a h/e was a mini radiator

it works by taking out hot fluid to the h/e and the h/e gets more wind flow so it cools faster.

also i think ill get the ott canned tune but everything else i can get cheaper here

with the 60lbs with a good tune should it get ok mpg? or no

also i got that intense tune is trash i was just wondering if they where considered a canned tune as well.

i really wanna hit 300 hp with meth

ShortStack

A canned tune is any tune that is sent to you, NOT one that you get at a dyno, or one done using your car. A canned tune includes sending in your computer and having them adjust it...

60s will get same gas as any other injectors. It all depends how much fueling is used in your tune.

Winkdogydog101

also just an added problem i live in az and max ac is number 4 what it shoots out is equal to like low on any other car ive owned is there a way to fix this its summer in AZ and 100+ degrees would really like super cold ac

know **** huh mid 13 i like that i wanna hit high 12s cause i think it would be really funny to beat vets camaros sti evos none of which are that fast down here. ithere you buy cheap and poor a tone of upgrades in or buy expensive cars and no upgrades lol
