For superchargers, most don’t go over 12 psi with 91, and the motor isn’t exactly loving that much boost on 91. For turbos, since torque comes on earlier, unless you do progressive boost, it might be best to limit boost to 8psi.
So im just gonna run it at 8 psi, I drive it a lot on the weekends and when I get time off I go to meets the whole time off so if I ever wanna boost more I’ll just get a built engine. Any kit you guys recommend?
