Those twins can support a lot, but you won't have the fuel to fully take advantage of them, that's assuming you have the HO pump and stock injectors. The amount of boost will mostly be dependent on the amount of fuel and the way the turbos are tuned, you might see up to 40 or 45 psi.
35-40 psi should be seen with the Super B, I ran an S256 on my old VP44 truck and saw 43 psi, but that was with an SO VP44. I actually just installed a Super B today to replace the HX40 in the compound set on my 12V, it's a decent little guy.
