h/e?

headers/exhaust

Coblt ss super

no no he was talking to me, and h/e is heat exchanger

Hmmm..learn something new everyday. Like LSJ said, expecting super good numbers from a GTO is just like the 14.0 times coming from the Cobalts. The potential is there, but there are few people that know how to harness it

exactly what i mean

Coblt ss super

that is true, but i doubt a first time driver can run even 13.5 with a stock ls2 gto

Problematic

talk to sk360, his first pass in an auto gto was a 13.52, first time on a drag strip

the GTO's rear end suspension is a lot like a Corvette's in the sense that it is setup to handle vs hook up.

So they do receive massive amounts of wheel hop when launched hard. Another issue with them is, they have a Torque Management setting that is quite aggressive from the factory, so hard shifting is not allowed. the computer basically sets a hesitation in between shifts to save the transmission from being beat on.

Another issue is heat soak. They put out IAT sensor near the radiator, and it is quite slow to update. We can pull upwards of 16 degrees of timing if our IATs read above 140F, we begin pulling timing at 83F.

So a quick tune to remove the IAT issue and TM settings, a relocation of the sensor to the airbox, and replacement of a faster sensor ($50), you've basically unlocked all computer limitations of the GTO. The C6 Corvette is the same way, although its TM settings are not as limiting.

true but only way to find out if i can take this kid is to do it and have a video camera around so i cna show u guys wat the outcome was

An auto, yes...The manual versions of the GTO takes a bit getting used to. I drove a couple and they were much much different then the Cobalts

So basically your saying if you take someone who has never driven a GTO before they would run worse than a 13.5, just like all of the 15 second SS/SC's out there then?

I love how you say that list of 12 second GTO's is because the are just short of NASCAR driving experience. Sorry dude it's called being a car guy after drivnig your vehicle for a while you learn **** like where the front and rear end are for parking, ground clearances, shift points and HOW TO DRIVE IT.

It's almost funny that some of you think a 270whp SS/SC can beat a GTO yet you didn't even know they could run 12's.

Most of you will glady state that a 375whp 03/04 Cobra can run mid 12's but are dumbfounded when we tell you a 355whp GTO can run high 12's.

Some of you are really going to be astounded when I tell you that stock LS1 F-Bodies have also dipped into the 12's.

Coblt ss super

yeah this kids is manual and he cant drive for nothing

Problematic

Just to give you guys a heads up, a tune and $600 headers have put GTO's into the mid-low 12's on average. Like I stated above, theyre limited badly by their stock computers.

Headers-$600
Cam-$400
Heads-$1300
Pushrods-$130
Pedders Backhalf Suspension-$550
H pipe/mufflers-$300
Drag Radials-$500

Now I'm aware this is a budget build, but thats what i like to go after

Low 11 second quarter mile times - priceless Not saying the SS/SC is a bad car, it definitely is not, but I just wanted to open some of your eyes on what moves a GTO.

for every stock gto that runs in the 12's, theres an ss/sc that runs a low 14

codyss

Thats why the first mode to may car was a tuner. It wasn't for the 20HP but for the removal of Torque Reduction/Torque Management and the change to IAT tables that won't retard until 104 degrees.

And the IAT is mounted in the MAF meter it is general engine heat that is causing the problem not the radiator.

jester

The manual is ALOT different than ours, but think about it, fwd to rwd. but now that I have had the car about 2 weeks I can go through the gears well and dont miss any shifts. When I first got it I couldnt hit third for the life of me... now I can bark the tires through 4th

rob fast06ss ran the 12.86 with 272 whp and around the same tq. Don't gto's dyno closer to 340 stock?

Problematic

it's the radiator, theres a reason why people relocate it away from it

it depends. some do low 340s, some hit high 350s

Theres also something called power:weight ratio. Did fast06ss run on drag tires? (I dont know a lot about cobalts, we got a local guy here who runs 13.40s with about the same power, but he is traction limited)

What I find dumb about this arguement is though, what are the chances youre going to run into another performance enthusiast with a stock car?

I love cars, my car is no longer stock, so you're not going to catch some off guard inexperienced driver in a stock car here

I certainly wouldnt post about beating a "stock" vehicle that is typically faster than mine, modded vs modded.

jester

Didnt he have DR's?

lsjwannabe

iTrader: (1)

yes hooiser qtp's to be exact

Problematic

so what if the gto had hoosier qtp's?

jester

So put those drag radials on the gto and your gonna see about a 3-4 tenth difference in that time

1gmfanatik

DR's on just about any car that has decent power will drop the quarter times at least a couple tenths

Problematic

I know that, what I'm saying is, that it doesnt put that 12.8 cobalt in the ballpark with one of the faster stock gto's

the dr's/qtps on a gto would put them into the mid to low 12s

jester

except the cobalt, then it drops like .6 maybe more haha

dude over here ran 13.1's on stock tire

jester

ok, so theres 1 driver probably pretty heavily modded and ran a 13.1 @10x.xx
there is 4 or 5 gto's that ran in the 12's bone stock. 108-109.x

I have the rest of my cooling mods comin by the end of the month. Once I get axles, I will let ya'll know what mines capable of with minor bolt-ons. I don't want to drop the hammer at the local track an snap an axle right yet, don't have the loot for em. Atco raceway is known for being prepped really well too
