Danny Foerster has spent years working in the automotive industry, specializing in fuel injection, tuning, and programming. As an air-cooled Volkswagen enthusiast, he saw the need for an EFI system that was reliable, easy to install, and truly designed for the everyday VW owner. The result is the Forster Performance plug-and-play fuel-injection system. In this episode, Danny explains how he developed one of the most comprehensive EFI conversions available for a stock Volkswagen engine. The goal was simple: create a true “set it and forget it” system that works right out of the box. No more...

Back in June at the Luft Zeigen show I had an opportunity to sit down with Danny a a.k.a. Danny Alvarez one of the old-school lettering guys that let a lot of cars back in the 80s cars like red alert, bad temper, bad temper too and many more. We sit down with Danny talk about what it took to get into the business with lettering and how that all started and some of his history short interview it's pretty good. Also, William Nera fresh out of death row, and now on the path to make things better he's got a new book out where he works with trying to help solve murder cases. Good to see him trying...

This week we put one more piece together with the bakersfield crew V-Dubs LTD. October 1987 was the month the "Chamange Notch" graced the cover of VW Trends Magazine. It was a really cool notchback sitting on some cookie cutters with a 1904cc engine. Dave showed that car for a while until the fatal run with California Highway Patrol changed the future for that car. Some say the car ended up in Japan some say the car is here who really knows but it's a wild story. We talk about starting from the bottom as an employee at Barth parts. Being overlooked in the succession plan and as fate would have...

First came the “Bug Eye” Baja kit, pioneered by Miller-Havens and helping launch a whole new look for off-road Volkswagens. But the evolution of the Baja Bug was just getting started. After finding success with the Sandwinder dune buggy, Don Rountree and R&H Fiberglass turned their attention to fiberglass bodywork for the Volkswagen Beetle. Around 1972, Sandwinder introduced what would become one of the most recognizable Baja Bug designs of the era—the “Wide Eye” Baja kit. Instead of mounting the headlights close together in the nose like the earlier Bug Eye kits, the Wide Eye...

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...

From the day he was brought home from the hospital in his father's split-window Beetle, it seemed Danny Allan was destined for a life surrounded by Volkswagens. As they say, he was born with the "VW Bug." For decades, Danny has been a familiar and highly respected name in the UK Volkswagen community. Many enthusiasts first discovered him more than 35 years ago when the Mk1 GTI he built himself earned magazine cover status, establishing his reputation as a talented builder with an incredible eye for detail. Since then, he's become one of Britain's most recognized air-cooled Volkswagen...

For over 40 years, Mark Prosser has been proving that you don't have to build a split-window Bus to create something truly unforgettable. While most enthusiasts chase the iconic early buses, Mark has dedicated his career to transforming 1968-and-later Bay Window Buses into some of the coolest, most performance-oriented Volkswagens on the road. Think slammed stance, serious horsepower, perfectly dialed suspension, and a no-compromise attitude. Mark takes what many people once overlooked and turns it into something that stops people in their tracks. One look at one of his builds, and you may...

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 under actual driving conditions.
Rather than relying on opinions or bench racing, Jake set out to answer the questions that Volkswagen enthusiasts have argued about for generations—with data.
In this episode, we take a look into:
-
The evolution of VW cooling system design.
-
The strengths and weaknesses of the various fan shrouds and cooling kits available today.
-
Why some cooling systems outperform others in real-world driving.
-
The relationship between engine displacement, compression ratio, ignition timing, and operating temperatures.
-
How cylinder head design dramatically affects engine longevity and cooling.
-
The impact of modern ethanol-blended fuels on air-cooled engines.
-
Common misconceptions about engine temperature and reliability.
-
The testing methods Jake developed to remove guesswork from engine building.
Whether you're assembling a mild street engine, building a powerful Type 4, or simply trying to keep your classic Volkswagen running cooler and more reliably, this episode is packed with decades of hard-earned knowledge backed by real-world testing and engineering.
If you've ever wondered what really keeps an air-cooled Volkswagen alive—and what actually works versus what has simply become accepted folklore—this is an episode you won't want to miss.
