That depends on how much boost you want. Spinning at crank speed it will pump roughly 2.1 times the engine displacement in. The boost pressure will depend on eficiency of the compressor and any intercooling. Intercooling will reduce temp and pressure giving more power for the same pulley ratio. Without intercooling I'd guess at about 18 psi boost. Probably fine with e85. With intercooling it would be closer to maybe 16psi boost and you may get away with PULP fuel with good tuning.

You'd never use it's full range though, you could happily use that charger on a 3-4 L engine.

Take this with a grain of salt as it's a bit of a thumb rule based guess.
