most compression with boost? (success stories?)
I'd shoot for 10.5:1-11.0:1 in an all out race application that will see 25+psi on race gas. Higher on Alky.
As superdave said the installed centerline and intake duration will play a big part in what you can and can't run timing and boost wise.

Alky is a wonderful thing.
A friend who races in Outlaw275 has a 94mm G-trim that he pushes 38psi through a 10.5:1 compression SBC. He runs M5, and could of gone higher if he wanted.

Bringing this one back up.
I have an 11.3:1 416 cu in engine and trying to see if I ran pump 93 with meth injection on top of it will I be ok or will I have to go to something like 110 fuel or c16 with meth?

I would say that's kinda high for pump 93 even with methanol injection.
Depends on the dynamic, but it's going to take a big ol' cam to bring it down enough to be considered safe on pump gas.
For pump and meth I'd want it around 10.5:1 maximum if the dynamic is right.

It has a cam for nitrous in it right now. It was spec'd by Geoff@EPS for L92 heads and a 300 shot. The specs on it are 240/251 .640/.637 on a 114. I would most likely change it for something more boost friendly if that looks like it wouldn't work.

Verdad Gallardo Even though that is a pretty big cam, unless you're going to run a blower like a centrifugal or a roots it's not going to work well with a turbo unless the turbo you're going to use has a 111mm or bigger turbine(which is what you should use on a 418) and even then it's slightly bigger than what I would use.
