I logged 37lb/min at 15-17psi (couldn't tell exactly, was driving and forgot to log bewsts), on 92 octane, with duty cycle under 65% on 1000cc delphis... The big difference between the 3586 & my turbo is that mine is old school and laggier. both are 75lb/min turbos.
The fact that virtually no tune at all other than "this seems like it'll be safe until I get a chance to do some tuning" seems to be working, at worst it's far more airflow than 260whp /ubbthreads/images/graemlins/wink.gif
Next weekend when I get a chance to play with the car I'll see if I can go log some runs for you /ubbthreads/images/graemlins/devil.gif
