[quote="DazC"][quote="M1CH43L"][quote="DazC"]There is no answer!!!





The Zetec based engines will be nicer to drive off boost and round town. The only other difference between the CVH and the Zetec engine is the CVH will keep pulling all the way to the red live where as the Zetec will slowly start to tail off, usually around the 5.5k rpm point. The Zetec will produce a big surge of torque which isn't helpfull for the gearbox or traction.

I would have to say this is utter tosh. If you have ZT engine that starts to tail off at 5.5k, thats down to YOUR turbo choice, ign timing and camshaft timing/choice.

It is not a feature of the engine itself.

At the end of the day, the zetec has a better flowing head and a larger capacity so is always going to make more power with less stress.
