I just blew the motor earlier this month, and a new one is going in next week. The new motor is street ported with 3mm apex seals. I'm ditching my PFS purple computer for a Haltech E6K. Other mods include PFS intercooler, Effini Y-pipe, PFS intake, PFS downpipe, Borla XR1, PFS catback, Cosmo fuel pump, Unorthodox Racing pulleys, and J&S knock sensor. What is a safe boost level and corresponding rwhp for fun street driving and track day weekends with this set up? I want to be able to drive the car hard without worrying too much about the motor going boom.

Thanks,

 

I can't tell you what to do for street driving, but I can suggest that you use 10 psi or less for track duty.
