supercharging · FF-0281

How much boost did the supercharged Flathead make on its first dyno pull?

On the first short pass, without leaning on it, the engine was at about 6.2 pounds of boost, which Steve says is almost exactly what his software predicted. The mixture was a little rich, which is the safe side, at about 11 to 1; the comment at the dyno is that these engines seem to run best at about 11 to 11.5.
