Message 93 octane. how much boost should my mods be able to hold? With 555s and stilled intercoolers I thought 16 to 17 was possible-safe although it will shorten turbo life if run that way. My mods are listed in my profile.

:What are you using for fuel?
:I would say no more than about 13 psi on Octane 91, 14-15 psi on Octane 93.
:As for running 17 psi, you should run race fuel or water methanol injection (with some safeties wired in to cut out your boost controller). If not, BOOM!
