One of the few good things to happen this year was Porsche perfectionists Singer teamed up with William Advanced Engineering (yes, the Formula One Williams) to make a new air-cooled, naturally-aspirated, 9,000 RPM, 500-horsepower 4.0-liter flat six. Finally, we can hear it yarp.


“British summer testing,” Singer posted today. “Four valve, air cooled Porsche flat six. Restored and modified by Singer and Williams.”

The yowl. Too good.
