They made a whole host of small changes that were almost imperceptible to the eye but aerodynamically significant. They also gave the car a nose-down rake by lowering the front suspension and raising the rear, both ever-so-slightly. All of the changes made the car significantly safer to drive at high speed. But the Ford Indigo was never going to be driven at high speeds as a show concept car – right?

There was one closely held secret design condition. It was secret because management would not want us to ‘overdesign’ the V12. The truth is, with clever engineering, planning for significant power increases adds very little weight and cost if you know what you are doing and if it is done up front.

The approach to understand what makes an engine run well is to look at the opening and closing of each valve. But whatever you want the valves to do, they’re actually doing something else, because you always have: Deflection, Inertia, and Vibration.

Steps to reduce the chances of valve-piston contact or crank bearing failure. The importance of cooling and RPM limits.
