Is the performance benefit offset by the cost associated with an Eaton supercharger?
In comparing a supercharged 3.8 liter, 2-valve/cylinder V6 engine with a non-supercharged 4.0 liter, 4-valve/cylinder V8, the supercharged vehicle will provide better power [torque], and at a lower overall cost, than the non-supercharged vehicle. This is due to complexity and tooling associated with the more complex 4-valve/cylinder engine.
