500whpSTI

so yea he got a 05 cobalt SS with a injen intake and i guess they welded a flow master Axle back on it. i drove it for a short period of time and it hit a little over 10psi in 1st i'd say about 12 not 100% sure. it has 16,000 miles about. i talked the guy down from 18,999 to 16,999 since the rim was curbed and the hood had a few rock chip's and a few other minor flaw's. i just wanted to drop in and see what you guy's think about the deal ill have pictures posted up soon of mine and his car and my 97 Z28. and i was going to tell him to get the stage 2 kit for the S/C what tuning software should he buy? or can it be done open source? Pm's or even reply's will be a great help. and if anyone's in the NY upstate area maybe we can all cruz thanks take care!

everyone uses HP tuners for tuning... or goes to a shop....
and, flow master Axle?

effex80

ehhhhh,

Its not a bad deal, but its not great.

18,999 is a bit high....

I got mine brand new 06 for 17,999. had like 700 miles.

If your friend is going to tune with HPT then there is no real reason to get the stage 2 from GM. Get the injectors, belt and a smaller pulley and just tune it. There are a few guys who do the tuning stuff in NY and I am sure they will chime in.
Welcome to the forum.

Axle-back exhaust..


like a Cat-back...... only his aftermarket exhaust is from the rear "axles" back to the tip

KillerBee

If he was hitting 10-12 psi it should have the stage 2 already

cincybalt

why? i am stock and i hit 10

zay52790

its a decent deal, i got mine brand new for 18500 fully loaded, 91 miles. also, i had like 2500 in gm card points so it ended up bieng about 16000 for it new.

KillerBee

Becuase stock they are at 8 psi of boost and you probably think you hit 10 psi cause 8 and 10 psi are like really close to each other

Smarty Art

Stock boost is 12psi after break in at a decent elevation. I could only see getting 8 psi if you live in really high elevation. I have stage 2 and I see about 15psi.

cincybalt

x2!.. im at 10ish maybe 11 right now

sealy

no offense, but what are you smoking?


technically stock boost should be 12.5psi. stage 2 takes it to 15psi.

KillerBee

Thats right i was thinking of something else i have stage 2 so yeah sorry guys i am not in my right mind today

yellowcobaltss05

stock is 12psi

Shortbus

crack kills! stock is 12

06SSousa

i can only get mine to 10 psi

500whpSTI

yea i herd they run 12 psi also. just from searching google. anyhow thanks for the info on the HP tuning ill let him know im going to try and talk him into doing at least injectors and a tune sin he allready has mod's do you think the injen CAI will hurt anything with no tune on this car? i've never looked into supercharged car's as i own a turbo car my dad own a dale jr edition monte SS witch is pretty sweet.

also what do these things usually put down to the wheel's before stuff starts to brake like axles and tranny's or anything in the drivetrain thanks ttyl

i dont know where you guys are getting 8 psi stock, i was seeing 12 stock, and 15 when i was stage 2 with no aftermarket exhaust

500whpSTI

also one more thing whats the cheapest why to get to stage 2? buy used stuff? i would have the injectors cleaned if so. the gm stage 2 kit is like 649 witch is kinda expensive for a chevy dont u think. i can get discount's from GM since im a dealer. but what im really asking stage 2 and a tune how much is he looking to spend? and is the tuning open source or does he need to buy like a reflash programmer like for my sti i have a Cobb Access port

the tuning comes with stage 2...

KillerBee

You can get stage 2 for 550 or so

500whpSTI

sweet does the dealer do that for 550? how does the tuning come with stage 2? i don't understand if the stage 2 only consist of a pulley belt and injectors The ECU will need to be Re Mapped in someway for these mod's

Tell your friend congrats on the new ride and to join up here! There are alot of really smart guys that can lend him some usefull information! I think all your questions haven been answered so I wont repete anyone!

Mike

The stage 2 kit is 550 from crateenginedepot.com then you have to pay for install also. Shouldnt cost more than 250$. Stage 2 does come with a new pcm program so tuning willl be covered. Stage 2 includes a code that you give to the dealer that is installing it. They then call GM and get a code to put into their tuner and it reprograms the PCM

500whpSTI

he doesnt have a computer lol so im doing the searches for him he doesnt want to have to much hp where it brakes axles and all so far i found out pretty much all i need to know except

the GM program i'm sure it's a very safe map correct? and a pro tuner could possibly get more power? i guess 250whp is the limit to where this car can handle well keep it very reliable that is whats the limit? 280? 300? i'm sure a good responsible driver can run 300whp with no issues.

So how do i get the PCM programmed if we are installing the part's are self? or does GM need to do this? I'm going to check the car out more tomorrow and measure the pulley for all i know it could be stage 2 i felt like more then 200whp it felt faster then my LT1 Z28 comaro.

just a few picture of my project soon to be done on July 28th

07 SS/SC

Very cool pics man!

The S2 tune does need to be done by a GM dealer. Also installing the S2 parts yourself will only give you a 12 month parts warrenty, no labor. If you have GM install the parts he will retain his 100,000 mile warrenty!
