I went to the track again with my cobalt and I am so disappointed that I have decided to trade it in on a truck. Idont understand it, I can out run my girls 02 camaro ss on the streets, my friends 04 mustang GT that has several mods, but when I go to the track my car always runs shitty and embarasses me. there cars run mid 13's and low 14's for the mustang and I can't get mine in the 14's for ****. something about the track pisses the car of and it just doesn't want to run. We have two drag cars and I have been racing everything from go carts to cars since I was little and I can drive the **** out of the car, but something about the track with this car that I just cant understand.

Thats strange because I have no problems getting into the mid 13s. Thats on street tires, without mounts, without downpipe high flow cat, without clutch/flywheel, and alot of other mods I have now. Practice makes perfect man, something is not right. What mods do you have? You may make out better selling the balt and no tradeing.

sounds like you just need more track time. but thats just my opinion. what rpm are your launching your car at?

an0malous

can you show us a slip or two?
maybe we can see where your losing your time.
any modding? what altitude are you at? what temperatures on your track days?
these things can really alter a cars time.
the average stock ss/sc with a new driver runs mid 15s where im at. but thats nothing to be ashamed of at 3000ft with usually poor air quality, and a new owner behind the wheel.

the amount of people with "x years" experience driving, who make similar comments is quite alot....these cars are not by any means easy to drive.
and they are truely a handful to launch at a track well.
regardless of what youve driven in the past.
it took me about 8 months before i was able to cut anything better than 2.3 60fts.

^ Very well said.

ALOT of people lose their time in the 60' mark, but you already knew that =), driver mod man

GordyD

I have the AEM CAI
Ingalls Stiffy
MagnaFlow Exhaust

Im launching at about two grand, it spins just a little then hooks up, when the rpms get high it will start to slightly spin again but nothing to slow the car down, just barely does it. I have two friends with cobalts that have less done to thiers, just intake and stiffy, and they both run mid 14's like they are nothing. I outrun them everytime on the road but something about the track the car just doesn't run right. I even had one of them take it down one pass and they ran worse than I do. we cant figure it out.

DaREDss

all I wanna know is you 60 ft

07 SS/SC

What are your 60" times like? Racing at the track is much different than racing on the streets. Post up a slip to see if we can help you out.

R&C_rallySS

What track do you go to? Were all trying to figure out whats going on here. It could be a combo of track prep, hot weather, and high altitude. With those mods here in PA you could run a 13.9-14.1 @ 99-102mph. Did you let some tire pressure out of the front tires?

fballman1987

that pretty much can make or break your quarter, we do normally tend to see higher trap speed and the time doesnt justify your speed.

GordyD

60' 2.121
330 6.186
1/8 9.895 at 74.06 mph
1000' 12.750
1/4 15.131 at 95.24 mph

This was at Atlanta Dragway in Commerce Georgia

DaREDss

do you loose boost at high rpm?

an0malous

are you powershifting?

that launch looks to be pretty good.

GordyD

nope the higher the rpm the more boost. after about 4800rpms I stay around 12 for the rest of the range

R&C_rallySS

Hmm, I'm going to go pull some of my stock time slips out to compare. Hold on a sec.

an0malous

hmmmm are you hotlapping and heatsoaking?
I assume your shutting the car down, and have at least 20 minutes or more between runs?

running 91oct or better?

joeworkstoohard

maybe something is pulling timing out?

GordyD

The only way I know to explain it and I know it sounds like an excuse but when Im at the track, it is like the power isn't thier. the car doesnb't pull like it normally does. I was stationed at FT. Huachuca Arizona where the altitude is 5,ooo ft and I would only get 8 psi and when I came back to georgia the car was running awesome. when I went to the track it felt like I was back out in arizona and it was like imediately after leaving the track the car was running like a champ. I was so pissed. I just dont know how to explain it.



I run 93oct and I shut the car down between runs and I also use ice to cool the supercharger between runs. I park it for a while just for me to cool down because im usually pretty pissed between runs.

eurochevy

thats like my time slip but bone stock haha somethings wrong with ur car or ur letting off the gas????????

DaREDss

that would really slow you down.

R&C_rallySS

With a 2.121 60" on your mods should yeild high 13 second 1/4th mile times. Lets see whats going on here.
Some of my Stock Time:
60' 2.382 2.238 2.282
330 6.275 6.140 6.203
1/8 9.401 9.273 9.334
MPH 78.42 78.15 78.44
1000 12.093 11.979 12.020
1/4th 14.345 14.241 14.266
MPH 100.04 100.06 100.02

It honestly looks like you may of left off the gas right before the 1/4th was over. Is that possible that happened? That does not make sense though either because your 330" time is real close to my best ones where I ran 14.2s. Do you keep her in 3erd gear or are you shifting into 4th? It seems like once your past the 330 mark the car just does not pull as hard. Thats not good because that is exactly where our cars should shine. After the 330 mark is where most of the SS/SC cars shine. Either way I have to give you major props because you can launch your car better then most people. +rep

DaREDss

def should be in 3rd unless you are trapping at 115 or higher

Hows your second to third gear shift because everything seem right untill then...

dude's car is falling on its face on the top end. either you are getting heatsoak, pulling timing due to knock, track has an uphill grade in the last 1/8th, or you dont know where the 1/4 mile ends and you let off too soon.

By His Slips It Looks To Me Like His Clutch Is Acually Starting To Clip At The Higher Rpms, Are You Driving It To The Track? How Hard Do You Drive It Before You Race? What Rpm Are You Shifting At?
