How much boost does Steve Coppock's Weiand 174 Flathead setup make?

The display engine has a Holley four-barrel on a Weiand 174 supercharger. With its pulley ratio Steve says it makes about 5 to 7 pounds of boost, which is modest by modern standards but about what a Flathead likes, because the engine is still limited by how well it breathes.
