I know most everyone here uses there cars for street duty and thus wants to run off pump gas. However, with the amount of time I run my car I don't car to buy the 110. My question is how much boost can I run on 110 without an intercooler, with say 10.5-1 comp?

For 10.5:1 on pump gas you're talking probably about 8psi, and they say every 2 points of octane is 1psi of boost. That would make me say you could do 16-18psi. I ran 10psi on 10:1 compression and a slightly larger cam last year just fine, and would've likely held up to the 16psi I run now if I had either pulled some timing or run race gas.
