    Anyone every go up against a cobalt SS?

    You picked a good day to race. The weather conditions definitely helped your Stang to produce more power than it would have on a hot, humid day. It appears that you're hooked.

    That shows 243 whp on a Dynojet dyno, which is nowhere near 260 real world whp.

    Anyone every go up against a cobalt SS?

    You know what they say about opinions. I'll believe your claim when you post a few dyno graphs that show stock turbo Cobalt SS's producing 260 fwhp.

    Anyone every go up against a cobalt SS?

    Awesome run for your 1st time at the track! And your 60' time is even more amazing when considering you ran with 4.10's on stock tires! Just wondering, what was the weather like, and was the track well prepped?

    Anyone every go up against a cobalt SS?

    Yep. The stock turbo SS does 0-60 in 5.5 sec. and the 1/4 in 14.2. The stock SC version does is slightly slower at 5.9 and 14.4. However, one would think that the SC SS would be a lot slower than the turbo, since its hp rating is much lower(205 vs. 260). Perhaps the SC gives it more...

    Anyone every go up against a cobalt SS?

    The stock 09 Cobalt SS has 260 hp at the crank, not at the front wheels. The FWHP is nominally 10-15% less than the crank hp for a manual, and 15-20% for an auto.

    Looking for a little more power...

    Great suggestions from the others. Here's one more for your consideration. If you had to shift into 4th gear before crossing the finish line in order to prevent hitting the rev limiter, then you can raise your rev limit to 7000 rpm, and shift at 6500 rpm. Depending on your drag radials'...

    Anyone every go up against a cobalt SS?

    Agree with fallenauthority. 20 lbs. of extra rolling inertia per wheel will put a big dent in your car's acceleration rate. Also, do a search for auto launch methods if you have any questions regarding that. There should be a ton of info on it.

    Anyone every go up against a cobalt SS?

    +1 on what the others said. Your S197 GT should beat your friend's Cobalt SS by at least 0.5 sec. in the 1/4 mile. However, that assumes a good driver mod for both cars, a decent D/A(moderate ambient temperature, low humidity, low elevation), and a well prepped track. Since you cannot do...

    Water Leak! (please help)

    Totally agree that accessing the interior of the firewall from the upper side is the recommended method if an 05-09 GT had been subjected to debris accumulation for almost 5 years, and it had not been routinely cleaned out during that time.

    Water Leak! (please help)

    Nice job on solving your leakage problem. Also, I'm sure that you eventually realized that it's much easier to pull them out from the bottom of the firewall inside the engine compartment, instead of accessing them by removing the windshield wiper cowl. And for everyone's reference, there is...

    Cold Air Induction

    +1 on getting a tune. Not only will it give your car more power as mentioned by others, but it will also make the throttle response a lot crisper.

    tire suggestions and how many miles did you pirrelli's last?

    If you're measuring 1/32" to the bottom of the tread(not to the wear bars), then recommend that you do not drive at higher speeds on wet roads.

    tire suggestions and how many miles did you pirrelli's last?

    +1 Driving habits and tire pressure(plus alignment/balancing as mentioned by bronco78) are huge factors that affect tire life. My stock Pirelli's have 25.5K miles, and should last another few thousand miles. They were frequently pressure checked, balanced, rotated, and aligned, but...

    0-60 times

    Many variables affect acceleration times, like traction(burning rubber in 3 gears is not helping your times as previously mentioned), altitude(high elevation slows accel.), ambient temperature(hot air slows accel.), relative humidity(juicy air slows accel.), manufacturing and assembly...

    AC/Engine...not sure...

    It will resolve itself within 20 miles or so of driving. Also, there's a procedure in the battery maintenance section of the owner's manual that facilitates the PCM in re-learning the idle strategy. And FWIW, strongly recommend that you do not allow your roommate to mess with your valuable set...

    Please Help!!

    Does the voltage at the battery terminals read approx. 12.6 V with the engine turned off, 9-10 V with the engine cranking, and 13.5-14.5 V with the engine running? Also, was the electrical system checked for excessive current draw?

    Cold Air Intakes

    Suggest making sure that the tune supplier has a tune for the CAI that you buy. The JLT is well known, and will not be a problem. But better check on the R2C CAI.

    Returned to stock / throwing codes

    Just curious. Why?

    Ok guys, convince me to get a tuner for my car

    A tune can cause emission inspection problems because it normally eliminates a lot of the PCM's readiness tests. The work around is to either install an emissions tune, or revert back to the stock tune and stock air intake.
