Do lighter racecars go faster?  Does mass even matter?  Should a mass target be a key design goal?  Low mass is often taken to be a virtue in FSAE/FS racecars, and often chosen as a design strategy for improvement in performance.  But does low mass really pay off? 

• Energy consumption * time

• (Throttle history, rpm history) * (BSFC -or- cumulative EV efficiency maps)

• Add up fuel injector duration

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 restrictor limits the amount of air an engine can use. The intake plenum smooths out the intake pulses, and makes it possible for other engines to compete with 4-cylinders. Asides on turbocharging.

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.

Stopwatches, garage beams, thermometers, cameras, chalk, zip ties, yarn, and smartphones.

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

This is a logic path for understanding the performance of your car in straight line acceleration. Understand the impact of gearing and power and torque curves.
