suspension and ignition setup need help

[Alan Roehrich]

Another engine builder, who is a friend of mine, and responsible for some historic performance, told me "it isn't so much that we know what makes the car go fast, it's that we know so much about what doesn't make it go fast, or even makes it go slower". All of that comes from testing, relentless, exhaustive, tedious testing. Unfortunately, there is no known substitute.
