hey there, i have a quick boost question,

i have a 93 fd,

i have

intake
hi flo cat
intercooler
catback
downpipe
255lph fuel pump
99 spec seq. turbos
and a mild street port.

i just bought a power fc and wanted to know what would a good yet safe amount of psi to boost.

i was thinking maybe 12-13? i dont know i'v seen people boost 15 lbs on stock twins and stock motors with only bolt ons and that seems a little too high in my opinion. just wanted to gather thoughts.

 

Take it to a good rotary tuner and they will tune it and tell you how much is safe to boost. Off the top of my head I doubt you'll hit 15psi on stock injectors. 12-13 sounds more realistic.

As dgeesaman said 12-13 psi would be my recommendation too.

 

take it to a good tuner like the others said.

 

a "good tuner" is hard to find... good luck with that be very cautious and ask a lot of questions and do a lot of research on the tuner you choose.

i would guesstimate that you'd be OK up to 12 PSI but you are essentially limited to how much fuel you can safely flow.
