I have a log of my car doing 4.54 60-100, which isn't too bad. Others have been able to pull 4 flats but they have better gearing.

SRT-4. Completely worked over. No idea on HP as this is the initial get it running and making power alright phase. Before this rebuild was 414 hp. Brother's goal is 700 hp w/o nitrous.

And he could only get 4.5 60-100? Cobalt SSs are doing ~4 seconds on the stock turbo.

Not yet tuned. A/F ratio is bottomed out at the limits of the O2 sensor. When it actually makes it to the dyno I'll update this thread. This is only on 20 psig of boost as well. The efficiency range of the turbo is in the ~30-35 psig range.

Which turbo? I'm debating GT30/GT35.
