ford made the openings on the front of the car as large as possible, they sealed around the rad and fmic so that as much air as possible would pass thru, they used a grill mesh that has 86% flow thru. my opinion is that this was all designed to cool the charge temps to a decent level on a racetrack at 100mph. Not on a dyno with a box fan. I think the charge temps are reaching unsafe levels (according to ford) on the dyno in one pull. if you want the car to pull consistently high numbers on the rollers you need a cooler that's designed for it. if you have never held a ford factory fmic then you just don't know what your dealing with, its a tin can compare to any aftermarket cooler out there.
A 2.3l cranking out 350hp/tq? why would that need high octane and cool charge temps? laugh out loud
