How much boost can I run on pump gas?

You better sleve the block and change the compression at least 9 to 1.. Get bigger injectors at least 550cc and a good tuner..But hey what do i know..
Getting an Alaniz short block build which includes sleeving the block, new rods and lower compression pistons at 9-1. I have 750cc injectors, so I should be covered there.

I've seen turbo car run 15-17psi on pump gas with 9:1 compression. Your limitation will be keeping the blower belt on above 15psi. As the pulley gets smaller, you loose surface area for the belt to drive the blower, as well as increasing blower RPM.
The Alaniz ported head will also have lower boost than a stock head with the same pulley, do to being more efficient.

Did you order 9:1 pistons for a stock head or did you give the chamber volumes on the head as well?
