But what exactly is the weight difference between an iron Zetec and an aluminum Duratec? Anybody know?


That's just it. The engines are fairly close in weight. Even at the far range of possible weight difference you are talking maybe ~100lbs for a stripped down Zetec compared to a more well appointed Duratec.
That's .1 seconds or so at the track. (not even taking into account the fact the Duratec makes more power & has a much better powerband!)

I would sure love to see video considering this small nitrous shot took off well over 2 seconds. (which is BS just considering the physics involved in that!)
