It's difficult to give you an exact hp number because different dynos are calibrated differently. Additionally, time of day, air density, air temps, etc, all play a role. Finally, different types of dynos will result in different numbers. Dynojet are well known for producing higher numbers than a Mustang dyno.
This is my dyno... 2005, PC3, full akr ti race exhaust. Tuned. Sea level.
