I know this thread is a little old but I was still hoping to get some info.
Lets say my goal was to hit 400awhp with a Ford Flex while running only 91/93 octane pump gas. Would that be doable?
Other then upgrading the turbos, exhaust, intake, what else would I need? Will I need to upgrade the fuel system? How would I go about doing this when the stock EcoBoost motor uses a mechanical fuel pump?
If there is a way to upgrade the fuel system, and lets say I do it, what would be the maximum I could now aim for on 91/93 octane?
I'm looking at picking up a Ford Flex EcoBoost and was trying to set aside a budget on mods after I buy it (Budget for vehicle is $30k CAD used, current budget for mod is $5k-$7k CAD, or roughly $5600 USD)
