Uprated Cams - BHP Gains?

Fact 2 - Handling is about chassis rigidity, geometry and suspension setup. Remember: A Ferrari 599 weighs 30% more than my 1100kg 306V6. But they handle well, don't they?

The thing you haven't taken into account though is the position of that weight. The XU engine sits at a 30 ( i think) degree angle shifting the weight back towards the middle of the car. The V6 when fitted to the 306 sits upright meaning the weight is all sitting right over the front. This does make a fairly big difference to the handling of a car!
