how much wood could a woodchuck chuck if a woodchuck could chuck wood?
as much as is needed to avoid knock. safe? probably around 4, 5 degrees? depends on temp and a few other conditions. make sure your muffler bearing is well greased though...

On some of the stuff below, maybe 12* advanced or more. Just be sure to remove your cat first. Truthfully, there are too many variables. We need more info about your setup. But if you're going to run that much boost on even good pump gas, it would be dumb not to have a Bipes (at a minimum) to control timing. For $175, you can set your base to 14* to keep all your low end power, and pull out as much as you need up top.

If you're interested in adding some good fuel for a trackday or a dyno day, just call your local speed-shop and they should be able to tell you where the local hot-pumps are. If you've got a track nearby, guaranteed a gas-station close-by will sell the good stuff.
And yup, the Sunoco 110 stuff is leaded, which will eat the ceramics(or whatever) out of your cat.
If I remember correctly, the only reason for the lead was as an anti-knock agent. Now that refining techniques have made better gas cheaper, lead is out. I might be talking out my *** about that though.

yeah, the lead basically makes the gas burn slower. the lead greatly reduces its likeliness to ping. back in the day the lead was in the fuel because the octane was lower (i believe) and lead basically can take the place of octane to a point, and older cars didnt have hardened valve seats. newer cars do of course, so the leaded fuel isn't needed anymore. unless you're boosting the crap out of your car.

as juhanis implied, lead is also a lubricant. So between that and the anti-knock properties it's pretty good stuff.
Apart from the potential for lead poisoning, that is
