it’s good to have goals and everything but... what will be the weak link that breaks at 600-650 hp on a 5700 pound 4x4?
This is something that is overlooked often.
Ford engineers along with their quality assurance team builds the truck with a redundancy and a reliability factor that exceeds operating margins for a wide range of uses.
When you start upping the ante by pressing the horsepower numbers.... there is no question you are using up those reliability margins.
The more you press the power... the more likely it will break... and the more likely it will have a shorter operation life.
I won't lie... I have a tune... intake... and soon an exhaust.... I've pushed the power totals for sure...
But I'll stop there.... I've made the mistake of pushing the power limits too far in the past and what you end up with is something you can't enjoy because you're always fixing it.
