Are your HP #'s at the wheels or the crank? My 06 Charger is putting down 480 to the wheels on 5lb of boost.
Yeah, you have a 5.7L V8 and higher compression.
I have a 2.0L 4 Banger running 8.5:1
So lets see here, since we are comparing apples and oranges.
Charger 5.7: 84.21hp per liter or 60hp per Cylinder. Charger 6.1: 78.68hp per liter or 60hp per Cylinder. Eclipse: 260hp per liter or 130hp per Cylinder
