stock fuel system + 95oct + BT-28 + 16lbs?

[turbolarry]

For one night only I might look to up the boost. I currently have the SBR BT-28 set at 12lbs due to stock injectors, pump, ad 91oct. Is it knock or fuel issues that prevent me from raising the boost to 16lbs? Will filling up with 95 oct. let me do this or will I just be to lean? I don't have a logger so I won't know my IDC's, knock, or timing. I can monitor stock o2's and EGT's. Anyone with experiece please.

I don't think it will be enough to allow to run 16lbs. If you had at least a fuel pump, I'd say try it and watch your EGT's very closely.

Still it's not a good idea.

Raise the octane to and the boost to 14lbs. and see where it goes?
