I read over and over that the FR9 motor was designed to run cooler and would have more HP. BS ! This engine is a flipping pile of crap that gets spanked at every race. Ford waisted three years developing this boat anchor of a engine and now are getting embarrassed every week. I catch hell every Monday Morning from my big mouth co workers because I was a Ford/ Roush racing fan. I bailing to the Stuck throttle racing team. Toyota racing !
