Engine boost at what rpm?

[Subafury]

4-5PSI @ 2000RPM is with the boost tap closed (max boost 7PSI)

11.5PSI @ 2000RPM is with the boost top open
(Unrestricted waste gate action till 11.5PSI)

Big difference between 'factory' & 'Open'

ooo this up pipe gets more tempting each time i hear of it. (....hmmm group buy...)

what do ya reckon is the most amount of boost an ea82t could handle before she starts blowin things?
im running 10 atm but wondering how much more she'd handle

With an IC 14psi then you will need to pull the heads off to put some decent head gaskets in before going higher
