Lets Talk Dubs

Air-cooling a Volkswagen engine has always been as much science as it is art. For decades, enthusiasts have debated which fan shroud cools the best, what compression ratio is ideal, which cylinder heads run the coolest, and how today's fuels affect engine temperatures. This week on Let's Talk Dubs, we're joined by one of the most respected names in air-cooled Volkswagen engine development—Jake Raby. Jake shares the incredible story behind the extensive cooling research that changed the way many enthusiasts think about building reliable, high-performance air-cooled engines. Beginning in 2006, Jake embarked on an ambitious cross-country journey in his famous blue "BluebonicPlague" Beetle, outfitted with more than 20 sensors strategically placed throughout the engine. Every mile of the trip generated an enormous amount of real-world data, with over two gigabytes of information recorded to analyze everything from cylinder head temperatures and oil temperatures to airflow characteristics and cooling efficiency und
