I hate questions like this. How much power a pump can support is a case by case deal. There are a lot of factors that can limit or extend how much power it can support. The biggest ones are altitude will show the pump maxing out early, and how much boost it takes a motor to hit X amount of power. Also diff dynos register different along with corrections factors and weather.
Absolutely!. SO many factors like BSFC, actual amount of boost ran, camshaft profile, it will spank an svt focus pump though for sure.... and (500hp with 8lbs and 500hp with 16lbs is WAY different)....
