I think you mean BHP. If so, the normally aspirated 4.2L engine produces 300HP @ 6,000 RPM. The supercharged version produces 420HP @ 6,250 RPM.

Technically, seeing how your car is about 10 years old now, a 10% loss wouldn't be out of the question (depending on your mileage), so you are more likely around 270-275 BHP.
