ok well with the new 2.0 SC Ecotec engine being a big craze right now, i was excited to see one at the local track last night. But to my dismay it wasnt all that great. It ran a 15.1!! That was really sad. Has anyone else seen the new SS and Redlines running at the track and what have you seen them run?


2006 Black Cobalt SS Supercharged G85
13.91@102.77

I am POSSIBLY running my SS on the 13th...I really can not see this car run at 15.1 it has a lot of power....but we will see won't we...MT tested the SS at 14.4 @ 99.3....Mine has the lsd so it should lock up or you know what I mean really well....

might have been bad driver....any idea what your elevation is where you live? that has a lot to do with it too...

You beat me to it I was just thinking about it and I figured i'd add that to it.....But man how's the car?

Definitely the driver, we all know the car is more than capable of a 15.1. It was probably the guy's first time at the track, so you have to cut him some slack

Watch someone who is experienced with the car take it down the track, and they should be pulling a mid 14 pretty easily - especially of they have the optional limited-slip diff.

elevation?, maybe I am wrong, but I didn't think that it mattered, being that the supercharger, compresses the air, can someone shed some light on the subject?


kyle

^^ No

Elevation has a big difference, even if you are force fed

There was a big discussion in the boost forum about this

Hotter air is thinner and you lose power
Cold air is more dense, you gain power
Reason the use for inter/aftercoolers

Goes the same for elevation
The higher up the less dense the air is, so you will lose power
Sea level is the almost the most dense you will get, you gain power


See the logic?

yess i figured that the air is less dense, but the charger would make the air more dense,
but I see that the charger does not change the density of the air, just compresses it, I understand thx. lowfire


kyle

Very true!

Chargers compress air at a certain CFM (Cubic Feet per Minute)

A cubic foot of air at a higher altitude wille have less air in it than a cubic foot a sea level

Its not just about density, its about oxygen content. Less dense air contains less oxygen. Less oxygen = less power. If there is 1 part per cubic foot at 100 feet elevation, and .5 parts per cubic feet at 1000 feet, then if a turbo charger can compress 100 cubic feet at any elevation, the higher elevation would have less oxygen, and make roughly half the power.

ive read all kinds of different numbers from these cars

a guy on the redline forums ran a 14.3 with a @!#$ty 2.3 sec 60'....and he only has an intake and exhuast

canadian driver mag tested the redline at 15.3??

this was said stated earlier but, mags are getting the cobalt at a steady mid-high 14's from what ive read

i think with a decent driver i dont see how you cannot break 14's....or maybe they are really that slow?? i duno i havent seen either run in person yet


one question tho....the ION redline and the cobalt ss s/c are identical performance wise right??? there was no change in the gearing to fix the "tall 2nd gear" or any other thing that would make one faster than the other?

SS has LSD option, Redline does not I believe

Other than weight difference, I think that is all

It could also have to do with the break in period. The governor wont unleash the full power until after a certain # of miles are put on the motor.

^ And if anything RL is lighter and has a better wheel size too for drag racing 17 vs 18s. Looking at it's ingrediants on the car, it looks to be the performer out of the 2.

As for someone mentioning the 14.4 @99.3mph sec runs that is only half the story. On that same test, they managed 15.4 to 100mph. So that is saying the real time for 1/4 mile is in 14.9-15.2 range, just by looking at their graph. But that is magazine racing and well.... blah

Here too man. At Moroso Speedway in West Palm Beach, FL. In August a couple of buddies and I saw a Redline in 4 runs average very low 15s. 15.1-15.4 range. Upper 50 degree weather and like 6 feet above sea level, hey it's FL. lol
So ya man you are not alone.

they dont do the 1/4 runs and the all out accel at the same time do they?
im asking
but if they dont
i can see how they could not do so well in the 0-120 or however high they go


and i know ga and fl are uber humid which doesnt help racing

^They do actually

They have a machine that calculates and records times every 10 mph until a preset speed i.e. 100, 110, 120 mph. Part of which the 1/4 mile is calculated in there too. But they do not do only one run, they do multiple runs. Take out the fastest and slowest and calculate the median time.

As for the humidity, it is humid, more so toward the beach. But Moroso is in the smack dab middle of FL (east-to-west). I din't know the humidity % for that night. All I know it that night was cold cuz I was wearing and we all asked each other, were even in FL anymore?

elevation is very close to sea level, im in michigan. We dont have mountains or high grounds, just alot of water. It was a cool 50F day.

Thats what the competition package is for

Just like hte performance option for hte cobalt, the competiton package offers the boost gauge, LSD, fog lights, and 17" Powdercoated rims.

Whereas the Performance Package for the Cobalt comes with the Recaro Seats and the LSD. The LSD is not standard in the cobalt SS/SC.

But a guy on redlineforums.com ran a 13.9xx with intake and exhaust.

^^^hey when is that competition package going to be avaliable??? i e-mailed saturn about it and the guy had no clue what LSD even was....

It's still not available!? I thought it was already..........that surprises me.

OMG a redline/cobalt forum and there hasnt been any bashing yet. well wait till wesman comes back and realizes that mrgoodwrench replied, it will turn into a war. but yes the cars are not very fast at all, i saw 2 RL and 1 ss run on friday night, best out of all the cars was a 14.9 and that was a RL with over 6k miles on it. the other cars didnt break the 15's.

well it could be a bad track or bad track conditions, theirs thousands of reasons.


-Borsty

seems like theres always an excuse when a SS or Redline doesnt perform as well as car and driver did in it. Hmm anyone else here think that chevy set them up with a better car to pull better numbers?


2006 Black Cobalt SS Supercharged G85
13.91@102.77

The Cobalt SS, if it weighed 2900 lbs, should be pulling about 14.8's constant (after break-in and everything).

This is the average for it. Some will be higher, some will be lower, it depends on the driver, traction, the track, humidity, tire pressure, fuel tank, hell it can be hundreds of reasons why the car didn't perform well.
