But we'll end up getting smoked by the end of the 1/4 with that 103 trap. It seems that car is putting a bit more to the ground than the Solstice but the FWD hinders its launch.
Doubt it, since the cobalt probably has more traction issues then we do, this loss of traction would increase its trap speed at the end. I hit a 1.9sec 60 footer at the track, i'd like to see a fwd do the same on stock tires.

Are you use they were running the gmpp kit or the same tune gm ran at topeka with 425lbs/ft of torque?

Thats a good observation that I didnt make myself. I would like to add though that these guys seem to be complaining about the cars as crunch time approaches. These are not the best drivers and they know if they screw up theyre out. Its a lot easier to blame the car for your slowness. Aside from the guys that spin out they seem to stay together pretty well and these problems only seem to show up after they spin.
The stock tune can have problems stalling and restarting after a spin. This is not specific to the Kappa. Other cars have this issue as well. It can be as easy as fuel getting away from the pickup point to not getting on the clutch quick enough and allowing tires/drivetrain/engine rotate in reverse momentarily amoung other things.

ya, I took that into consideration but they were definately going into limp mode, you saw it on a few drivers that couldn't get power and had to use their skilz to stay competitive, I believe one in the lead went to limp mode, no turbo and still stayed comepetitive
this was indeed an ecu problem as far as I can see

These drivers and pit crews knew something- if they were willing to go so far as to use brake pads with missing material, I wouldn't put it past them if they were using the Stage II, and doing the wastegate rod mod, and blowing the stock hose clamps right off. That'll result in no boost. I think one of them also cracked their intercooler. Racing puts significantly more stress on the car than daily driving, even if you get on it. Hitting the rumblestrips at speed, other cars etc.
Heck, stock we're running into issues with the hose clamps not holding. Imagine more boost. Then if you're leaking boost and reading it in the MAF- you're gonna run extremely rich.

I don't think you can race in limp mode, no bad how mad your skillz are!

Off topic: Through out the entire show (the course of a month for filming) people were blowing hoses, loosing power, and other issues which have shown up after the Stage II kits as well.
I've talked (e-mailed I guess) to three of the drivers now and neither of them had any issues with the kit, except that there was more power and it caused traction issues, excessive speed issues, etc. None of them have indicated any issues in performance, lack of performance, or any negative changes to the car with the Stage II kits vs. without the Stage II kits.
I will continue to seek information from the only people that can talk about the kits... the drivers on Setup II. So far, nothing indicated problems with the kits, and all who have spoke up have said positive things.

The Stage II kits would do well to include T-Bolt style clamps for all the hoses including the throttle body ... are you listening GMPP?

The GM person(s) specifically said the reason we have not brought it out yet is because we want to make sure it last. It is easily making 312 BHP (Flywheel) and with this type of increase it has to meet our requirements for durability.
They were not only addressing the Solstice/SKY community but also the new Cobalt SS and the HHR SS, since it is the same engine on all the cars.
Another thing he mentioned was a display (Cobalt SS) that they are working on that would give a lot of information about the engine.
The new Cobalt SS coming out has a boost gauge on the pilar and he said that it was not enough and the display would take the place of the boost gauge.
There was also a GXP that GM supports that is pretty much stock as far as the engine components other than a special tune been use for drifting.
Is making around 330 BHP, using ALL the stock parts such as IC pipes and intercooler, same hoses and clamps. The suspension of course is upgraded but that is expected since it is a drift car. The tires in the back are 245x45x18 and the fronts are 245x40x18 Cooper's (They are an sponsor), it also has Norm's side fenders and rear diffuser.
The calipers are the same as ours, do not know what type of pads it is using.
On the rear brakes they added a second set of calipers that is control by a hydraulic e-brake, looks a strange seen to sets of calipers in the rear.
Just for the record the Drift car you are speaking of is making 335 HP on 110 RACE GAS, it is making over 400 ft /lbs of torque and totally not a streetable car. I have talked with Nubbs (Dan ) a good bit he is local to me, been trying to get a look at the car. It also does not have a stock intercooler it has a Hahn, they are a sponsor. The numbers that Nubbs posted are from GMPP, that is what they made at the factory on the engine dyno. The other team Drifting a Solstice posted the same numbers. Both Nubbs and the other team Gardella Racing, also drag race Cobalts. Gardella Racing Thread

I don't think you can race in limp mode, no bad how mad your skillz are!
You couldnt be more right.
Limp mode = no go.
Trust me, I know it well.
It isnt just the loss of boost, but locking the throttle possition in place (35% if I remember correct), clamps down on timing, and just about anything else it can grab on to.
Remember it is designed to get you to a dealership/service garage just short of grenading... there is NO GO when you are LIMP....
Depending on the reason for limp mode, you can bring things back online by simply cycling the key to off and then restarting (while rolling for those that like that sort of thing).
Sometimes you are there for good until you remedy the problem and/or reset the ecm.
I actually think you can get better performance out of a car that has blown off an intake hose than one that is in limp... least that is my experience. Either way, you are SOL.

I also talked to Nubbs while at NOPI and the GXP did not have the Hahn intercooler on.
I was there and saw the car and talked to him and the driver many times.
The Hahn intercooler will be going in at a later time. I never said anything about been streetable, all I was pointing out was the car having basically ALL OEM parts as they come from the factory and generating all that power from the race GM tune.
What is remarkable is how ALL the OEM parts can handle that type of power.
So if and when the GMPP stage kit comes out with what is probably about 315 BHP on 93 octane ALL my OEM parts can stay. I rather save my money for parts that actually improve the performance vs their cost. Those will be suspension pieces as oppose to IC pipes, CAI's and an IC. I may consider the later after the GMPP stage kit is on the car.
The Hahn intercooler is need it because the OEM IC is at it's limit for what GM race tune can deliver.

Actually just looking at the description of the LNF leads me to that one. The bottom end of the engine is very solid...maybe the cast piston sheds some doubt. I'd only wonder about the
