est. 1/4 mile, what other mods do i need???
 

as some of you know, im looking to buy an ss.
i found this LSJ, super clean, with a couple mods.
i would call this mildly modded, correct me if im wrong.
its an 06 and it has the following perf mods:
stage 2 supercharger kit, magna flow cat back exhaust, headers and down pipe, an aftermarket intense pcm, a hurst shortshifter, k&n air filter, eibach springs, new tires.
the guy told me the pulley was a 2.9". and dont remember what headers or down pipe
they are.
if i buy this i would later on want to put a 2.8" in it.
what other mods is this missing for me to be safely run a 2.8" pulley, also any
mods you would reccomend adding (including different tune),
and lastly, whats 1/4 times do you think this car can do like this?

bump

Should run high 13s but theres only one way to find out lol

This ^^^. Too many variables come in to play to say "it will do XX.XX in the quarter". Good traction with a good driver you will be in the 13's.

you'll need at least 60's to pulley down.

just out of curiosity what color is the car?????

^^^^^^^^exactly my same question!

Tune would be your first thing to do. intense has a history of blowing up pullied setups.

Yea I would definitely get a custom HPTUNERS tune

cooling mods also if u pulley down anymore.

With just a 2.9,DP,Intake and a tune 13.5 and below is possible.

If this is a yellow one with an eibach sticker in the rear quarter window then be warned. Last update was low compression on all 4 cylinders.

this is the car. Has a theft recovered title and not the original drivetrain
2006 Cobalt SS Supercharged!



also as someone else said intense is known to run lean so a retune is a must. With 42lb injectors and a 2.8 you will be ok but get cooling mods and a retune at least for knock


I am running a 2.8 and 42lb aka gm stage 2 injectors. My injectors are maxxed but afr is still in check. I run my car hard too in south florida .

I had an intense tune for a couple years with no problem.
People keep saying this yet, Ive never seen anywhere a
"Blew my engine up because of an intense tune" thread.

Ive seen engine blew for other reason threads but never
because of an intense tune. Everyone says other peoples
engines blew from intense, but no one has said it was their
engine. This is starting to me to sound more like just hearsay
and stuff that people keep saying rather then something that
is true.

The Dyno results I have posted here are all on INtense Tunes.
You can see that im running 11.5 AFR at WOT, and my cruise LTFTs were in the -10 reigion,
That is NOT lean.

I dont know who said what or where all this intense tune stuff is comming from,
but I'm going by personal experiance, never had an issue with it.

yeah congratulations. you still went a half second slower than i did completely stock. even with your Intake, Pulley, Injectors, INTENSE Tune, Header, downpipe, Heat Exchanger, Torque Dampener, and Hurst Shortthrow Shifter

A Tune to be on the safe side.

WOW Congradulations on beating a rookie on his first time down the 1/4 mile :cssNET:

Im a rookie and I ran 14.4 at 98 with just an intake.. a custom hp tune over the intense crap would do wonders

twas mine as well.

Ok I suck happy?

But my point is: My intense tune has not damaged my engine, and is not running lean

but it sucks

YOU asked what other mods u needed?? Custom Tune /Thread

but its probably still not at its full potential
