Tech talk with Fred Simpson the "Great Engine Debate"

There's been a lot of noise lately about engine performance, dyno numbers, and expectations—and instead of adding to the speculation, I brought in someone who actually lives this stuff. This week, I sit down with Fred Simpson for a good conversation on cylinder head technology, porting and polishing, and how all of it really translates into horsepower. Fred breaks down engine combinations, airflow calculations, and what kind of power you can realistically expect from different motor setups—while also being honest about the limitations he's run into over the years. We also get into camshaft technology and ask the big question: has cam design kept pace with modern cylinder head development? To round it out, Fred shares his unfiltered take on exhaust systems—what works, what doesn't, and which designs he says flat-out choke an engine. If you're into engine theory, real-world results, and no-BS technical insight, this is one of those episodes you won't want to miss. www.vwtrendsmagazine.com www.rosswulf.com use LTD10 for a discount   www.letstalkdubs.com    

I made it a whole two weeks into the new year without buying a new project… and then I blew it 😆. This episode kicks off with the story of how I ended up with "Pookie's Dream," the iconic VW Trends August 1991 cover car. We touch on what that car meant to the hobby back then and why it still matters today. But the real heart of this episode is The Great Engine Debate. A recent dyno session sparked a massive discussion after comments posted by Ross Wolf revealed an engine that didn't deliver the expected results. What followed was an explosion of opinions—over 65 comments deep—covering engine specs, dyno expectations, real-world performance, and long-standing air-cooled engine-building philosophies. We get deep into the weeds on what numbers really matter, why expectations don't always match results, and how different builders approach power, reliability, and intent. To balance the conversation, we bring in feedback from both sides, including insight from Jared Winton and a direct take from Pat Downs Performance on the topic. This is one of those discussions that never really ends in the VW world—but that's what makes it so good. Grab a drink, settle in, and enjoy another episode of Let's Talk Dubs, where history, opinion, and air-cooled passion collide.

San Leandro, California—an industrial Bay Area city shaped by its Portuguese community and a deep-rooted Volkswagen culture—holds a story few outside the neighborhood ever knew. Tucked away behind an unassuming fence was a Volkswagen collection unlike anything else in the region. For years, local kids would stop, peer through the slats, and take it all in: early Beetles, split windows, rare convertibles, stacks of glass, and parts that hinted at decades of careful accumulation. It was a forgotten archive of Volkswagen history—silent, untouched, and unexplained. Then came the revelation. The cars belonged to Stuart Alexander, the owner of the Sausage King facility and the man later convicted in one of San Leandro's most infamous criminal cases—the murder of health inspectors at his warehouse. A crime that shocked the community also cast a long shadow over what had once seemed like a harmless automotive mystery. In the years that followed, the Volkswagen hoard was quietly dismantled. With the help of a volunteer assisting the family, the cars were sold off—often at fair, reasonable prices—and released back into the Volkswagen world. One by one, these forgotten cars reentered the scene, restored, driven, shown, and enjoyed, largely disconnected from the dark chapter that once surrounded them. In this episode, we Me & John Limnios explore the intersection of true crime and Volkswagen history—how a legendary Bay Area VW stash came to be, how it disappeared, and where those cars may be today. Many of them are still out there, living new lives, their origins unknown to their current owners. If you own one of these cars, recognize the story, or have information about the San Leandro VW hoard, we invite you to reach out. This is more than a crime story—it's an unfinished chapter of Volkswagen history, and together, we may be able to trace it back to where it began.   www.letstalkdubs.com www.vwtrendsmagazine.com www.rosswulf.com use code LTD10 for 10% off

What if the Volkswagen you built as a teenager never really left you? In this episode, we get into the incredible full-circle story of David Lawler and his 1971 Volkswagen Beetle from Southeast England. David bought his very first VW at just 14 years old, poured years into building it, and saw that dream rewarded when the car landed in a Volkswagen magazine in 1995. But life changes. Priorities shift. The unthinkable happens—and the car is sold. Watching your first show-winning Volkswagen drive away is a regret that never fully fades. For decades, the Beetle would resurface in David's life, always just out of reach. Nearly 30 years later, he finally gets the chance to buy it back—only to discover it's far worse than he imagined. Rather than restore what was lost, David makes a bold decision: start over and build something entirely new. The result is a radically re-imagined 1971 VW Beetle—a modern, hot-rod-inspired machine that stands completely apart from anything else in the Volkswagen world. From extensive paint and bodywork, to chop-top modifications, a full roof conversion, and a cartoon-style window treatment, this build rewrites the rulebook. The hot-rod-meets-custom interior seals the deal as a true one-off. That risk paid off in a big way. The car was selected Top Five at the VolksWorld Show and went on to land the cover of the November 2025 Volkswagen magazine. This episode covers the emotional journey, the design decisions, the fabrication challenges, and what it means to let go of the past—only to build something even better. If you love custom Volkswagen Beetles, VW show cars, chop-top VWs, and real stories from the global air-cooled scene, this one is a must-listen.   www.letstalkdubs.com www.vwtrendsmagazine.com www.rosswulf.com use code LTD10 for 10% off of your order www.ssaircooled.com ICON pistons here

The East Coast of Canada is cold, and the car season is short — usually May through October. New Brunswick isn't known as a hotbed for the air-cooled Volkswagen scene, but when the VW bug bites you out there, you're all in. Terry grew up in a drag-racing family, and everything changed the day his father gifted him a convertible Karmann Ghia. That single car sparked a lifelong obsession with all things air-cooled VW. From flat-towing a '67 Beetle over 2,000 miles from Alabama, to drag-racing a Herbie-themed bug, to eventually owning the legendary Save-A-Bugcampaigned by Jack Shacettie — Terry's passion has taken him across the continent. His vacations? They weren't for relaxing — they were spent in Southern California, wrenching in work clothes at Jack's shop just to be part of the action. Now retired from a career in insurance, Terry finally opened a small but official shop in New Brunswick. Not for business — but to help keep his cars and his friends' cars on the road. Terry's collection tells the story of a life dedicated to Volkswagens: "Cinco," his all-original 1955 Beetle, bought with just 25,000 miles. A 1955 Kombi running an SO-42 interior setup. And his driver — a 1950 split window, restored by Dr. Dick Christiansen, which he puts real miles on. So many cars, so many stories, and a lifetime of air-cooled passion from one of Canada's most dedicated VW enthusiasts.
