Im pretty sure CHEF's old ED was on 14 psi on a completely stock engine.

20psi+ with the right compression and good tune.

Pyroay wasn't comfortable running his any higher than 16psi with standard bottom end and got just over 300rwkw off that

Not for long with a completely standard bottom end... And you would want a far from standard head to deal with that boost

im not saying its the ringt thing to do, but it will take it.
thats if u can get the comp low enough with stock pistons. there is also a supercharged el xr6 here in perth that has around 440rwkw and runs 10.1's down the 1/4 witch still has the stock bottom end. just remember that ford pistons are already high silicon cast, witch is what most of these guys are running eg tufed6 460rwkw 21psi

think this is almost an impossible question to answer
by stock bottom end do you mean stock CR or are you going to decompress (cut into chambers or thick gaskets)? how long do you want it to last for? what sort of engine management will you have (state of tune makes a big difference). Boost is a measure of restriction, so the more efficient your engine is (intake, head, cam, exhaust) the less boost you can safely run.
