For a long while I've been getting a weekly email from a great online magazine called Autospeed. It is an informative and results based magazine covering a host of different areas of Automotive design and modification.
I thought a recent article worth sharing on measuring performance modifications. Most can't afford regular dyno tests, but this article shows how you can get meaningful real world measurements using a simple stopwatch and all within the speed limiton public roads. A worthwhile read I reckon, and thought I'd share
