I've been watching this video:
I don't know if you're referring to this, but even without knowledge about forced induction, I can see the problem it's not the turbo.
At minute 1:10 I can see a moderated or normal launch, I can hear the turbo spinning but the engine didn't raised the top RPM, so I assume the driver didn't pressed fully the accelerator nor fast. Call it a "Driving Miss Daisy" start.
At minute 1:36 the things change radically, hear how the turbo starts spinning, the wheels also start spinning fast and when the driver release the brake... someone stopped recording. Call it "The Fast & The Furious: Director's Cut". (Everybody knows in a director's cut edition, the best scenes are removed...)
At minute 1:46 everything goes really bad, notice the sound of the turbo and the engine trying to spinning up slowly, but something is retaining from spinning fast.
I think the most probably can be the brake by itself due a overheating or a half hooked piston in the caliper. Maybe the driver didn't disabled the TC/StabiliTrack controls or whatelse. But after watching the minute 1:36 I have no doubts about the STS turbo system is working as expected.
Consider also the asphalt and the tires, both look giving a good grip. Nobody tried to do the same with his stock (or mostly bolts-on tuned) V6 over a good asphalt with the tires warmed? I tried, and mine can't do that.
Just to mention if someone watched the Lingenfelter supercharger video for the Camaro V6 (
), look the technique used by the driver. He doesn't start accelerating with the car completely stopped. He releases the wheels a bit, then he brake & accelerate at the same time.
Obviously a supercharger it's totally different than a twin turbo, but it's not the same start accelerating with the brakes fully pressed like in the STS video, or do it like as seen on the Lingenfelter video.
Well... that's all. And please, excuse my english.
Cheers,
ducted.
