Boost what can run without IC

As I assume many of you don't have ICs.

With me running 92/93 octane gas what is the maximum boost I could run. I don't want to experiment without asking and confirming

On the stock fuel system , 10-12 psi should be perfectly harmless.

it won't get hot....

I'm going to run 10 PSI for now and it's just now starting to get a tad cooler in the mornings and afternoons. Once "southern winter" comes around I'm gonna boost 12. Then back to 10 in the summer

Everybody in the tuning world says 8 is the max that is safe without an intercooler (that you can be run all the time). Of course I believe this too but nobody on this site listens to me. You can get away with maybe 10psi in the cooler months with no issues but other then that I wouldn't suggest running 8psi for more then a short duration.

But once you look at it in the big picture how often will you actually be running peak boost in normal driving
