Jay Gillotti on the Porsche 936’s Turbocharged Dominance at Le Mans

The hosts are referring to Porsche chassis/production codes that identify specific cars and their generation/variant. In Porsche circles, these codes are often used instead of (or alongside) model names because they map to the car’s exact history and configuration.

Pirelli is the tire brand sponsoring the show segment. The sponsor message emphasizes tire performance traits like grip and noise reduction, which are especially important for racing and high-speed road use.

VIN stands for Vehicle Identification Number, a unique 17-character code assigned to a specific car. It’s used for registration, history checks, and identifying the exact vehicle when joining clubs or verifying ownership.

The Porsche 917 is an iconic Porsche endurance race car from the late 1960s/early 1970s. Here it’s used as a size and design reference point for the Porsche 936, including wheelbase and overall construction similarities.

The Porsche 914 is a smaller Porsche sports car mentioned as a visual comparison in the discussion of how the 917 and 936 look in size. The host contrasts the 914’s “tiny” appearance with the larger proportions of the 917 and the compact look of the 936.

A homologation car is a production-based model that a manufacturer must build in minimum numbers so it can be eligible for certain racing classes. The idea is to ensure the race car is derived from a real, sellable car rather than a completely custom prototype.

The FIA (Fédération Internationale de l’Automobile) is the international governing body that sets motorsport rules and regulations. Here, it’s referenced in the context of how Porsche anticipated rule changes that affected what cars they needed to build for racing eligibility.

A homologation platform refers to the specific production car (or closely related base) that meets the rulebook’s minimum-build requirement. Once Porsche had enough 911 Turbos built, it could develop racing variants for the next classes.

Group 4 and Group 5 were FIA racing categories used in that era to classify different types of race cars. The segment explains that once Porsche met homologation requirements, it could build modified cars to compete in those groups.

“Silhouette racers” were cars built under rules that required the exterior body shape to resemble the production model, even if the internal engineering was largely race-specific. This let manufacturers pursue aerodynamic and mechanical improvements without fully abandoning the recognizable street-car form.

The “World Championship of MAKES” was an FIA series focused on manufacturers (“makes”) rather than individual drivers. In this segment, it’s the series where Group 4 and Group 5 cars were eligible, shaping Porsche’s strategic concerns.

The “World Sports Car Championship” was a major FIA endurance racing series. In the segment, it’s described as the venue for Group 6 prototypes, which could potentially win overall races and overshadow class winners.

To “homologate” means to formally certify a car for a racing category by meeting the rules—typically including production or specification requirements. The segment contrasts Group 6 prototypes, which “don’t have to homologate at all,” meaning teams could build more freely for racing.

“Group 6 prototypes” were FIA prototype race cars built under rules that were less constrained by production requirements. The segment highlights the strategic fear that these prototypes could dominate overall results, making class wins less memorable.

“9-35” is described as another Porsche program number associated with a specific FIA class (Group 5) in the segment’s explanation of Porsche’s numbering logic. It’s mentioned alongside 9-11 and 9-34 as the expected focus before the Group 6 concern.

“9-34” is presented as a Porsche program number tied to a racing class (Group 4) in the speaker’s explanation of how Porsche’s internal numbering mapped to FIA categories. It’s part of the logic behind the later “9-35” and “9-36” naming.

In the segment, Porsche’s project to build a Group 6-ready car is described as becoming the “9-36,” which is the internal program name that ultimately corresponds to the Porsche 936. The numbering is explained as being tied to the intended racing class (Group 4/5/6).

The segment mentions an unusual early designation, “9-17 stroke 50,” which the speaker says doesn’t make sense because it wasn’t actually a “9-17.” This is part of the story about how Porsche’s internal naming evolved before settling on the later number scheme.

“9-26” is described as the next internal designation after the earlier “9-17 stroke 50” label. The speaker then says Porsche later aligned the numbers, tying them back to the intended FIA class structure.

Can-Am (short for “Canadian-American Challenge Cup”) was a major sports car racing series known for powerful, purpose-built cars. The speaker is using it as a reference point for which Porsche components and design approaches were carried over.

In this context, “transmission” means the gearbox and related drivetrain components that send power from the engine to the drive wheels. The speaker notes the Porsche 936 used the transmission from the 9-17 Can-Am car, showing how Porsche reused proven hardware.

“Steering gear” is the mechanical system that converts the driver’s steering input into movement of the wheels (through linkages and the steering mechanism). The speaker groups it with other reusable components from the 9-17 program.

Wheel hubs are the mounting points at each wheel where the axle and wheel connect. They’re critical for locating the wheel correctly and integrating with bearings and braking components in a race car.

A tubular aluminum space frame is a lightweight chassis made from many small aluminum tubes welded into a rigid “3D” structure. It’s designed to be strong while keeping weight down, which is crucial for endurance racing cars like the ones being discussed.

“Plastic porches” is a nickname for lightweight Porsche race cars that used plastic bodywork over a tubular frame. The term highlights the shift toward saving weight and speeding up fabrication for competition.

“Six cylinder” refers to an engine with six combustion cylinders. The number of cylinders affects engine length and packaging, which is why the speaker connects it to needing a spacer between the engine and gearbox.

A “gearbox” is the gearbox that contains the gears used to select ratios for different speeds and conditions. The speaker says Porsche had to create a spacer between the gearbox and engine because of packaging constraints.

Renault is discussed as Porsche’s primary competition in the era, with the speaker emphasizing Renault’s state-backed resources. The segment frames Renault’s involvement as both sports car racing and a parallel push toward Formula One.

“911 RSR Turbo” refers to a turbocharged 911-based race car Porsche had already run before the 936 era. The key point here is that Porsche had real-world turbo development data from an earlier 911 turbo program, even though it wasn’t homologated and had to run as a prototype.

Turbocharged means the engine uses a turbocharger to force more air into the cylinders, which allows more power from a smaller engine. In endurance racing, turbocharging also changes how the car makes power and how it manages heat and fuel consumption over long stints.

A flat-six is an engine layout where six cylinders sit horizontally in two banks, creating a “boxer” style configuration. Porsche’s flat engines are a big part of their racing identity, and the segment highlights a 2.1-liter flat-six turbo used in the earlier 911 program.

Normally aspirated means the engine draws air in naturally without a forced-induction device like a turbocharger or supercharger. In Group 6, the rules allowed normally aspirated engines of a certain size, which is contrasted with Porsche’s smaller turbocharged option.

Force induction is the general idea of using a device (like a turbocharger) to force more air into the engine than it would get naturally. The segment uses it to describe the turbocharged route Porsche could take within Group 6 rules.

The ACO (Automobile Club de l’Ouest) is the organization that runs the 24 Hours of Le Mans. In the segment, it’s contrasted with the FIA over rule-making authority during the mid-70s.

“Group” refers to FIA race car categories used in the 1970s to classify cars by design and eligibility. Saying Porsche ran Group 4, 5, and 6 means multiple car types/entries from Porsche were competing under different category rules on the same track.

A “sprint” in endurance racing is a shorter race distance than a full 24-hour event, but it’s still long enough to stress tires, brakes, fuel, and driver stamina. Here it frames the Nürburgring event length for the Porsche 936’s season opener.

Qualifying determines the starting order for the race based on lap times. “Qualified second” means the car was the second-fastest in the qualifying session, giving it a strong starting position.

This phrase is describing track conditions—rain leading to low grip and reduced traction. In racing, wet conditions can dramatically increase the likelihood of loss of control, especially at corners.

A throttle cable is the mechanical linkage that opens the throttle to control engine airflow. If it “sticks,” it can prevent the driver from reducing throttle smoothly, forcing unusual workarounds during braking/slowdown.

Using the ignition key to shut the engine off is an emergency workaround when normal throttle control isn’t available. The segment describes how the driver had to turn the engine off to slow down, then restart it to continue.

“Customer” here refers to Porsche’s privateer or non-factory racing customers—teams that bought and raced Porsche machinery. The segment highlights Reinhold Yoast as a customer who won the race, showing Porsche’s reach beyond factory entries.

Cylinder wall temperature refers to how hot the inside surfaces of the engine’s cylinders get during operation. Excess heat can contribute to problems like reduced efficiency, accelerated wear, and in extreme cases engine damage—especially in turbocharged engines where heat loads are higher.

A “two-liter V6 turbo” describes an engine with a 2.0-liter displacement, arranged as a V6 (six cylinders in a V shape), and using turbocharging. In this segment, it’s used to explain Renault’s approach and the heat-management difficulties that came with it.

The Saab 900 Turbo is a classic turbocharged compact from Saab’s lineup, widely discussed among enthusiasts for its character and for the era’s turbo technology. The host mentions it as an example of how turbo cars could be loved but also raised reliability concerns in the 1980s.

“Active development racing laboratory” refers to the idea that racing programs are used to test and refine technologies under extreme conditions, then carry lessons back to production cars. The host is asking whether the Porsche 936’s turbo and heat-management learnings eventually influenced what Porsche built for customers.

This describes Porsche’s “racing-to-road” development philosophy: using lessons from competition to inform production car engineering, and vice versa. The segment frames it as a long-term strategy that helped turbocharging become central to Porsche’s modern street-car lineup.

The Porsche 91710 is referenced here as the first turbocharged Porsche racing car. It’s part of Porsche’s development lineage showing how turbocharging moved from race success into later street-car technology.

The Porsche 91730 is mentioned as the next step in Porsche’s turbocharged racing evolution after the 91710. In the discussion, it supports the idea that Porsche’s racing experiments directly influenced later turbocharged designs.

The Porsche 911 Turbo is cited as Porsche’s street-car counterpart to its race cars. The hosts use it to illustrate Porsche’s strategy of learning from both competition and road use when refining turbocharged engine technology.

In motorsport, “privateers” are teams or individuals that compete without being part of the manufacturer’s official works program. The segment asks whether the 936 later appeared in privateer hands, and then explains how Porsche limited factory builds and enabled certain customer-style efforts.

“Blueprints” are detailed engineering drawings used to build or reproduce a design. In this segment, the Kramer brothers built additional 936s based on factory blueprints, which is why their cars could closely match the original concept.

The Porsche 934 is listed among other Porsche racing cars the speaker says they learned about or cared about. In this segment it functions as part of a “greatest hits” list that makes the 936 stand out as comparatively under-discussed.

The Buick Century is a mid-size car from Buick, typically associated with mainstream comfort and everyday usability rather than purpose-built racing. In the podcast excerpt, it’s brought up in the context of claims about being “the greatest racing car of the 20th century,” suggesting the conversation is addressing how certain cars are remembered or marketed. That makes it relevant to a discussion about racing history and how people describe achievements.

The Porsche 962 is mentioned alongside the 956 as a car that “absolutely dominated in the 1980s.” It’s part of the comparison that positions the Porsche 936 as historically important but less widely known.

The Porsche 956 is cited as the younger/other side of the 936’s “middle child” reputation. The segment notes that the 956 “dominated in the 1980s,” helping explain why the 936 is less talked about.

Le Mans refers to the 24 Hours of Le Mans, one of the world’s most famous endurance races held in France. Because it’s a 24-hour event, teams focus heavily on reliability, pit strategy, and sustained speed rather than just short-burst performance.

Formula One (F1) is the top tier of single-seater open-wheel racing, with teams competing in a points-based championship across many countries. In the segment, Renault is described as shifting focus from sports car racing to Formula One after winning at Le Mans.

Sports car racing is a category of endurance and sprint events featuring production-based or prototype sports cars, often emphasizing reliability over long stints. The segment contrasts this world with Peter Schutts’ background, noting that sports car racing was relatively new to him as CEO.

Mechanical failures are breakdowns of key components (engine, gearbox, cooling, etc.) that prevent a race car from continuing. Here, both cars are said to have mechanical failures at Le Mans in 1979, which explains why they didn’t finish.

The Porsche 935 is another Porsche endurance/racing prototype from the same era, and it’s mentioned here as the car that wins Le Mans in 1979. The key point in the segment is that while the 936 campaign had issues and didn’t finish, the 935 still delivered a win.

Sebring refers to the 12 Hours of Sebring, an endurance race in Florida that’s a major stop on the sports car racing calendar. The segment uses it as Peter Schutts’ first race as CEO, setting up how quickly he gets pulled into the sport.

The Porsche 924 Turbo is a turbocharged version of the 924 used here as part of a development program. The speaker frames it as a stepping-stone effort while Porsche worked on the 944 program.

The Porsche 944 is a front-engine Porsche sports car that’s referenced as the target of a development program. In this segment, the 924 Turbo racing effort is described as supporting work toward the 944.

Boost is the extra pressure a turbocharger (or supercharger) provides to force more air into the engine. In racing, boost rules can strongly affect power and competitiveness, which is why USAC’s ruling mattered for the Indy 500 engine.

Methanol is a type of fuel used in some racing series. The segment says the Indy 500 engine was originally set up for methanol, and the team considered converting it to run on gasoline for Le Mans.

A chassis dyno is a test stand that measures engine and drivetrain output while the car is strapped down and the wheels are driven by rollers. The speaker notes that the team’s main testing was on the chassis dyno, with limited additional track testing before Le Mans.

“Lifted the tail” refers to changing throttle/braking inputs in a way that causes the rear of the car to rotate or become unstable. In racing terms, not lifting the throttle suggests the driver maintained consistent balance and traction through the corners for the entire stint.

A single-turbo setup uses one turbocharger to pressurize the engine’s intake air. Compared with twin-turbo systems, it can have different boost response characteristics, especially at lower engine speeds.

Twin-turbo means the engine uses two turbochargers instead of one. Using smaller turbos can reduce turbo lag (the delay before boost arrives), improving throttle response—an important goal for endurance racing.

“Spool up” describes how quickly a turbocharger reaches the speed needed to generate boost. Faster spool-up reduces turbo lag, making the engine feel more responsive when the driver demands power.

Water-cooled cylinder heads use coolant flowing through passages in the head to carry away heat. Moving from air-cooled to water-cooled heads lets engineers manage higher thermal loads and enable more advanced combustion hardware like multi-valve designs.

In racing, aerodynamics refers to how the car’s shape manages airflow to create downforce and reduce drag. Changes to aero are often aimed at improving top speed on straights while maintaining stability in corners.

A four-valve-per-cylinder design uses two intake and two exhaust valves to improve airflow into and out of the engine. Better breathing can increase power, but it can be difficult to package on an air-cooled head at the required heat levels.

This refers to the introduction of a cooled intercooler package on the car. The “hood scoop” and ducting described nearby are part of how the car gets enough airflow to keep the intercooler effective at Le Mans speeds.

The air box is a ducting/reservoir structure that manages airflow to key engine systems. In the 936’s case, the episode describes it as a signature component that feeds air to the intercooler, the cooling fan, and the engine intake.

IMSA refers to the International Motor Sports Association, which organizes major sports car racing in North America. The speaker mentions adapting the 936 concept for IMSA rules/competition to stay competitive.

Wind tunnel testing is a method for measuring aerodynamic forces and airflow behavior using a scaled model or full-size vehicle in a controlled wind environment. Here, Porsche used it to optimize air box/intake shapes for both intake efficiency and reduced drag.

Drag is the aerodynamic resistance a car experiences as it moves through air. Large external intake/air-box structures can increase drag, so race teams balance airflow benefits against aerodynamic penalties.

“Archival material” refers to content intended to be preserved for long-term historical record—like documents, recordings, or other records that can be revisited later. In this segment, they’re contrasting traditional pre-digital records with today’s digital media.

The Porsche 356 is referenced as an example of a classic model that might have been discussed as being “for sale” in a conversation from the 1960s or 1970s. The 356 is one of Porsche’s earliest production models and is a major historical reference point for the brand.

Oral history is collecting firsthand stories from people who were there, usually through interviews. In a car club context, it helps preserve details about events, cars, and culture that might not be documented in books or photos.

This segment is about the Meekum auction held at Indianapolis (Indy) and how the schedule is organized by price tiers and which cars are highlighted on later days.

The Porsche 959 is a late-1980s supercar known for advanced engineering and rarity. In this segment, the host calls out a specific “Comfort” edition, contrasting it with the more performance-focused “Sport” version and highlighting its low mileage and original condition.

The Ferrari 288 GTO is a homologation special from Ferrari’s Group B era, built to meet racing rules. The host brings it up as a value competitor to the Porsche 959, noting how Group B-related cars have been fetching extremely high prices.

“Group B homologation” refers to the process of building a limited number of road cars so a manufacturer could race a car in the FIA Group B category. Because these cars were tied to a specific racing rule set, many homologation models are rare and highly valued today.

“Tour de force” means an impressive achievement that showcases exceptional skill or capability. In this context, the speaker is praising the Porsche 935-era technology as being unusually advanced for its time.

Wrensport is a motorsport event/venue where rare cars are shown and discussed, often with a focus on track heritage and collector cars. The host says the 2019 Porsche 935 debuted there, anchoring when and where the car was introduced.

A “museum piece” is a vehicle preserved mainly for display rather than regular use. The speaker says this Porsche 935 was effectively treated that way—bought as an investment and kept rather than driven or raced.

Track days are events where owners drive their own cars on a closed circuit for practice and fun, usually with coaching and safety rules. The host is asking whether cars like this Porsche 935 are actually taken to track days or kept as collectibles.

“Street legal” means a vehicle is approved for public-road use under local regulations (e.g., emissions, lighting, and safety requirements). The host notes the car was never street legal at the beginning, which helps explain why it would be difficult to take to a track.

The Porsche 911 Speedster is a limited-production, open-top 911 variant focused on a lightweight, driver-oriented feel. In this segment, the hosts highlight a 2019 example with the heritage package and extremely low mileage, positioning it as a special auction “museum piece.”

A heritage package is an appearance-and-trim option that applies classic design cues to a modern car, often with period-correct colors, badges, and interior details. Here, it’s used to describe the look of the 2019 911 Speedster.

An odometer measures how many miles (or kilometers) a vehicle has been driven. Collectors often treat very low odometer readings as a sign the car has been lightly used, which can strongly affect auction and resale value.

A “livery” is the visual design on a car—paint, graphics, and decals. When people say “racing liveries,” they mean the look inspired by motorsport cars, often associated with specific teams or eras. The “quasi” part suggests a partial or toned-down version of that race look on a street car.

“Race-inspired livery” refers to street-car graphics that are designed to resemble what you’d see on a competition car. The speaker is expressing a preference for not having that motorsport look on a car meant for everyday use.

In Porsche racing culture, the “meatball” is the round sponsor/identity patch (often with a number) placed on the car’s front. It’s a visual shorthand for the car’s livery and race identity, so missing or mismatching it can feel “off” to enthusiasts.

“Not of the factory” here means the car’s appearance (the meatball/number setup) isn’t original or period-correct from the manufacturer or race team. In enthusiast circles, authenticity matters because it affects how accurately the car represents its intended history.

The Porsche 911 is the brand’s iconic rear-engine sports car, and it’s instantly recognizable by its silhouette and branding details. In this segment, the speaker is reacting to the “Porsche” script placement on a 911 and how it affects the car’s visual identity.

The Porsche 908 was a dominant prototype race car in the late 1960s, especially in endurance racing. In this segment, it’s referenced as the first time Porsche used the “Porsche” script on the car’s livery, tied to branding decisions during racing.

“Golf” refers to the Volkswagen Golf brand, which is famously associated with Porsche’s racing sponsorship and livery themes. In this segment, “Golf 917s” and “Golf Blue” describe a specific Porsche race-car color/sponsorship identity rather than a mechanical feature.

“Beetle” refers to the Volkswagen Beetle, a long-running model known for its distinctive shape and air-cooled heritage in earlier years. The host is talking about a light-blue Beetle from the early 1970s they drove in college, using it as a personal reference for color and nostalgia.

“M3” refers to BMW’s M3 performance model line. In this context, the speaker is comparing reactions to the idea of an M3 being offered as a convertible, treating it as a departure from what some enthusiasts expect from the M3.

“Exhaust note” is the character of the sound coming from the exhaust—its pitch, volume, and how it changes with throttle. When the host mentions hearing it without a top, they’re describing how an open-top setup lets the engine and exhaust sound come through more directly.

“Five-bolt wheels” refers to a wheel bolt pattern with five mounting bolts around the hub. It’s a common layout on many cars, and the speaker is contrasting it with center-lock wheel hardware.

Center-lock wheels are wheels secured with a single central hub nut/fastener rather than multiple lug nuts. They’re common on performance cars because they can speed up wheel changes and reduce unsprung/rotational complexity.

The Porsche Cayenne is Porsche’s SUV line. In this discussion, it’s brought up as a turning point in Porsche’s history and how the brand broadened beyond traditional sports cars.

Fender stripes are decorative graphics or paint stripes placed on the front fenders. In performance-car culture, stripe placement is often tied to a specific livery style and can affect how the car’s proportions and heritage cues are perceived.

The Chevrolet Corvette Grand Sport is a performance-focused Corvette variant. Here it’s mentioned as a visual/style reference point when discussing what “came out” first—likely comparing livery or stripe design cues.

The hosts are discussing how race-inspired styling elements—like stripes—can carry over from track cars to street cars. This is a design philosophy topic: whether it looks good, feels authentic, or distracts from the car’s intended identity.

The speaker references the Dodge Challenger as another visual reference for the stripe “vibe.” This is a design comparison rather than a discussion of a specific Challenger technical spec.

A “parade” at a car event is a slow, organized drive where participants show their cars to spectators. It’s a common setting for photographers and fans to capture details like paint, decals, and styling choices.

Decals are stickers or graphic transfers applied to a car’s body or windows, often used to show club membership, sponsorships, or personal styling. In enthusiast circles, decals can be part of the car’s “identity” and can also reference racing history or specific events.

In endurance racing, the pits are the service area where teams stop the car to refuel, change tires, and make adjustments. Because multiple cars may run for the same team, teams use visual cues so drivers and crew can quickly identify which car is coming in.

The nose panel is a bodywork section at the front of the car, often including aerodynamic surfaces. In racing, changing the color of the nose panel can act as a fast visual identifier for different cars in the same team.

This refers to the event location for a Porsche Club of America (PCA) gathering mentioned in the episode. It’s a social and motorsports-adjacent calendar item rather than a technical automotive topic.

PCA.org is the website for the Porsche Club of America, which organizes events for Porsche owners and enthusiasts. The episode directs listeners there for registration and event details.
