Christopher Runge of Rünge Cars

The Porsche 911 is defined by its rear-mounted air-cooled flat-six heritage and distinctive rounded body shape. In this episode, Maurice uses it as a reference point for how coachbuilt hand-formed bodywork can still influence the newest 911’s look.

Coach building is the traditional practice of constructing a car’s body by hand or in small batches, often tailored to a specific customer. The episode frames Runge Cars’ approach as part of the old European coachbuilding culture, where metalwork and form are central to the final product.

A flat eight-cylinder engine (often called a “boxer” layout) places two banks of cylinders opposite each other, creating a low, wide engine profile. In Porsche context, this is a key part of why the brand’s engines feel distinctive and help with vehicle balance.

The Ford GT is a mid-engine supercar built to deliver high performance with a focus on track credibility. It’s mentioned here alongside coach-built classics to set the scene for the kind of enthusiast crowd and cars that drew Maurice to the Runge display.

Runge Speedsters are the custom sports cars Christopher Runge builds, positioned as a modern continuation of classic roadster styling and hand-fabricated coachbuilding methods. The episode treats them as the specific car Maurice saw at the event, and they’re central to the story of how Runge’s work caught his attention.

The Helios is a Gullwing-style coupe that’s described as “race-inspired,” meaning its design language borrows from motorsport aesthetics rather than being purely a production-car look. In this conversation it’s framed as a “future-past” concept—vintage in feel, but aiming at the kind of future design people expected decades ago.

The Mercury Monterey is a mid-size car from Mercury (a Ford brand), known for its classic styling and role as a family-oriented model. In the podcast, it’s referenced through a specific example—the “Helios” and a “Gullw…” mention—suggesting a custom or special vehicle based on the Monterey. That makes it relevant as part of a story about distinctive builds and automotive history.

A “Gullwing” coupe refers to a door design where the doors hinge upward, opening like a bird’s wings. It’s a distinctive bodywork feature often associated with iconic performance cars and is used here to emphasize the Helios’s retro-race styling.

“Unfinished business” is used here as a metaphor for promising design ideas from the 1950s and 1960s that never fully made it into production. The speaker argues that optimism and bold concepts existed, but many stayed on paper instead of becoming real cars or consumer products.

Retro-futurism is the design idea of imagining the future through the lens of an earlier era’s technology and aesthetics. Here, the speaker credits the Helios and other builds for taking that retro-futurist concept and turning it into a real, drivable car.

“Post-war German racing cars” refers to the era of German motorsport after World War II, when racing engineering rapidly evolved and produced distinctive, influential cars. The speaker says their inspiration comes from that period, implying the builds borrow engineering and styling cues from that racing lineage.

E10 and E15 are gasoline blends that contain ethanol: E10 is 10% ethanol and E15 is 15% ethanol (by volume). These blends are more sensitive to water contamination, which can contribute to phase separation and fuel quality issues.

Phase separation is when fuel components separate into different layers instead of staying mixed. With ethanol-blended gasoline (like E10 or E15), water contamination can separate from the fuel, which can reduce fuel quality and cause problems at the pump and in engines.

Octane rating is a measure of how resistant gasoline is to knocking (premature combustion) in an engine. If water contamination and phase separation push the fuel out of spec, the effective octane can drop, which can lead to drivability issues or engine protection strategies.

“Head pressure” is the pressure created by the height of a fluid column. In the episode’s context—pumping from a tank buried about 20 feet underground—it affects how hard the system must work to move contaminated liquid and how the plumbing needs to be designed. It’s a key concept in fluid-handling systems, not just a general “pressure” idea.

A “patent” is legal protection that gives an inventor exclusive rights to make, use, or sell an invention for a set period. The speaker says they didn’t even try to patent their technology, instead focusing on being first to market and selling to customers. That choice affects how they monetize the idea versus licensing it.

The Mercedes SL 500 is part of Mercedes-Benz’s SL “Sport Leicht” roadster line, known for luxury plus a V8-powered grand-touring character. In enthusiast circles, it’s often a popular used-car project because many examples are mechanically straightforward compared with more exotic classics.

The Porsche 912 is a classic Porsche model closely related to the 911 era, often seen as a more accessible version of the lineup. It’s significant because it shares the recognizable Porsche sports-car layout and look, while being part of the brand’s early history. The podcast mentions it in a personal story about finding a 1967 Porsche 912.

An English wheel is a metal-shaping tool used to form and refine sheet metal panels by gradually stretching and smoothing the metal over a set of rollers. It’s a key tool in traditional coachbuilding and custom bodywork because it helps create smooth, compound curves.

The Lotus 7 is a lightweight, minimalist sports car concept that became famous for its go-kart-like feel and focus on driver involvement. It’s also widely associated with kit-car culture, so mentioning it in a coachbuilding context signals a build philosophy centered on simplicity and weight savings.

The Chevrolet Corvair is a classic American compact car known for its rear-mounted engine layout. The podcast references it as part of a large pile of parts and projects, emphasizing how much “Corvair stuff” was involved. That context makes it relevant as a platform that supports restoration and collecting.

“Post-war German racers” refers to the racing cars and racing culture that emerged in Germany after World War II. This era is known for innovative, often small-batch engineering as manufacturers and private builders tried to compete with limited resources.

“Eigenbau” (German for “built by oneself”) describes home-built or privately constructed racing cars rather than factory production machines. Glockler’s post-war German Eigenbau racers are associated with Walter Glockler, who developed and raced unusual, experimental cars using Volkswagen-based components.

The Volkswagen engine reference here is about using VW’s air-cooled flat-four architecture as the basis for racing development. In this story, Walter Glockler is described as pushing that engine’s limits and adapting it for a mid-engine layout.

A mid-engine layout places the engine near the center of the car, typically just ahead of the driver and behind the front axle. This helps balance weight distribution and can improve handling response compared with front- or rear-engine layouts.

Formula V refers to a racing formula/class concept associated with lightweight, open-wheel-style competition. In the transcript, it’s used as a reference point for the kind of chassis Glockler’s mid-engine setup resembled, before the “formula V” name became established.

“350 sixes” refers to inline-six engines with an approximate 3.5-liter displacement (often discussed as “350” class) being pushed hard for racing. The key idea is that Glockler was extracting maximum performance from that engine family.

“Porsche parts” here means components supplied by Porsche to a privately built racing car. The story highlights how Porsche supported and collaborated with private builders early on, using their parts to improve the performance of Glockler’s machine.

The Porsche 550 is an early Porsche race car best known for its lightweight, competition-focused design and its role in establishing Porsche’s motorsport reputation. In this episode, it’s specifically tied to Porsche’s collaboration with private builders, including the early “first five fifties” produced by the same coach builder.

C.H. Feidenhausen is named as the coach builder who made the early Porsche 550s (the “first five fifties”) in the story. Coach builders were specialist firms that constructed or assembled the body/chassis for racing and specialty cars, often before modern mass production.

Herman Ramelow is credited in the transcript as the designer/engineer behind the cars associated with Glockler’s setup and the early Porsche 550 production. The mention underscores how early Porsche racing success relied on specific engineering talent rather than only factory branding.

“Private tears” appears to be a transcription error for “private teams” (or “privateers”), meaning non-factory racing efforts run by individuals or small groups. The transcript contrasts Porsche’s early reliance on privateers’ feedback with Bugatti’s similar pre-war approach.

Bugatti is referenced as another historic racing-focused automaker that, like Porsche, benefited from feedback from people running its cars. The transcript uses Bugatti as a comparison point for how early performance development was influenced by private owners and racers.

“Bespoke” means custom-built to a specific customer or purpose rather than mass-produced. In racing context, “bespoke competition cars” implies a one-off or highly tailored race car built around the driver and intended events.

Walter Glockler is presented as the key figure behind building early competition cars using Volkswagen parts. The segment also links him to the VW franchise dealership in Frankfurt, which is described as the source of access to VW components.

“VW components” means parts sourced from Volkswagen. The segment claims Walter Glockler built an early car using Volkswagen parts, tying the car’s design to what was available through his Frankfurt dealership.

A “Porsche distributor” is a regional business that handled Porsche sales and logistics for a specific market. In this segment, Max Hoffman is framed as an early distributor who helped bring Porsche-related cars into the U.S. racing and dealer ecosystem.

Johnny von Neumann is mentioned as the driver who raced the Glockler Spider at Bridgehampton. The segment also notes that he later founded competition motors in Los Angeles and became a Porsche dealer.

Bridgehampton is referenced as the venue where Johnny von Neumann raced the Glockler Spider. It’s used here as a historical anchor point for early American Porsche/competition-car activity.

Frank Lloyd Wright is referenced as the architect who designed the Hoffman Motors showroom in Manhattan. The segment connects Wright’s early career and his relationship with Hoffman to the broader Glockler/Hoffman Porsche history.

Vashik Pollak Jr. is the person the host interviewed, and he’s presented here as someone with personal ties to Max Hoffman late in Hoffman’s life. The host says Pollak Jr. and his father stayed close to Hoffman until the end, including bringing him meals and running errands.

Max Hoffman was a major American car importer/dealer who helped introduce Porsche to the U.S. market in the 1950s. In this segment, he’s credited with pushing Porsche to build the 356 Speedster as a lower-cost model for the U.S. and encouraging Mercedes-Benz to produce the 300 SL as a production car after the race cars.

The Porsche Speedster is a specific Porsche roadster-style model/derivative known for a stripped-down, lower-cost approach compared with more fully equipped variants. In this episode, the host ties Max Hoffman’s U.S. influence to Porsche building a Speedster for American buyers in the 1950s.

The Mercedes-Benz 300 SL is a landmark Mercedes sports car that became famous for turning race-car technology into a production model. The host specifically says Max Hoffman persuaded Mercedes-Benz to build the 300 SL as a production car after the race cars came out.

A “1954 beetle pan” refers to the chassis pan/underbody platform from a 1954 Volkswagen Beetle. In this segment, it’s the starting base the speaker bought with the intention of building a custom Porsche-inspired “Romesh style” car.

“Romesh style” refers to a specific custom Porsche-inspired body conversion concept built from a Volkswagen Beetle pan. In the segment, the host describes a known example: a Romesh Porsche prototype where the pan is sliced and the body proportions are shifted to change how the driver sits, including a longer nose.

“Samba” here refers to the online Volkswagen enthusiast community/forum called TheSamba.com. The host says they read a story about the Romesh-style car being unearthed “on the Samba,” meaning it was discussed by that community.

The speaker bought a “Predator Formula V,” using it as the starting point for their first build. It’s a Formula V–class race chassis they could afford on a shoestring budget, and they’re treating it as a platform for designing and fabricating a new body.

MIG welding (Metal Inert Gas) is a process that uses a continuously fed wire electrode and shielding gas to create welds. It’s popular for fabrication because it’s relatively fast and beginner-friendly, but aluminum can still be tricky without the right setup (like a spool gun).

A spool gun is a welding tool used for feeding wire—commonly aluminum—more smoothly than a standard MIG setup. Because aluminum wire is softer and more prone to feeding issues, a spool gun helps prevent jams and improves weld consistency.

Metal shaping is the craft of reshaping sheet metal into a desired form—like body panels—using tools and techniques such as hammering and careful forming. In this context, it’s about learning how metal behaves so the panel fits correctly before welding it in place.

“Super light construction” is a lightweight-building approach aimed at reducing mass by using thin, strong structures and efficient materials. In practice, it often means building a rigid frame/armature and then forming the body around it so the car stays stiff without excess weight.

“Legetta” (as the Italians call it) is described here as a thin framework/armature. The key idea is that the bodywork is supported by a lightweight structural skeleton rather than a heavy traditional body structure.

An “armature” is a structural framework that provides the shape and support for the rest of the build. In custom car bodywork, it’s the internal skeleton that the panels are laid over and then attached to.

A “wooden body buck” is a full-size form used to shape body panels. Builders use it like a mold: they form the metal over the buck so the panel matches the intended contours before it’s attached to the chassis/frame.

“Weld it, rivet it” refers to two metal-joining methods used in custom fabrication. Welding fuses metal together, while riveting mechanically fastens parts with metal pins, often used where heat or access makes welding harder.

“Fixtured” means clamped and positioned using fixtures so parts stay aligned during welding or assembly. It’s a shop process term that helps ensure repeatable fitment and reduces distortion.

“Running gear” is the car’s functional mechanical package—typically the drivetrain and the components that let it move (like suspension and axles). In a rebody project, it’s what you keep so the car still drives normally even after changing the body.

The Viper is Dodge’s performance sports car line, and the podcast notes the name’s meaning (“poison or venom”) while describing it as an SRT-10 Viper chassis and running gear with a custom, bespoke body and interior. That’s why it’s discussed here: it’s not just the production car, but a modified build using Viper mechanicals as the foundation. The focus is on how the Viper platform can be adapted into a unique one-off style.

“Rungy” is used as a shorthand for Rünge Cars’ own design language—here referring to a bespoke body and interior. It signals that the exterior and cabin are custom work from the builder, not a factory kit.

“Cars and coffee” is a casual car meet-up format where enthusiasts gather—often in the morning—to show their cars, talk to other owners, and attract attention from the local community. In the transcript, it’s used as the reason the speaker brought the car out for public viewing.

The Shelby Cobra is an iconic American roadster built around a lightweight chassis and a powerful V8, famous for its raw, high-performance feel. In this story, Jason’s fandom helps explain why the speaker was motivated to build a car inspired by that classic style.

“Aluminum bodied cars” refers to vehicles that use aluminum panels or an aluminum body structure instead of steel. Aluminum can reduce weight and change how the car feels and handles, which is why enthusiasts often associate it with classic performance builds.

“Frankfurt Flyer 002” appears to be a specific numbered build in the speaker’s project line, tied to the car they were discussing earlier in the episode. The “002” indicates it’s not a generic model name—it’s a particular iteration/build that the host is referencing.

A jig is a precision fixture used to hold parts in the correct position while you build or modify a structure. Here, the builder had to jig the whole chassis so it could be cut apart and widened accurately without losing alignment.

“Slab-sided” describes bodywork with relatively flat, vertical side panels rather than smoothly tucked-in curves. Aerodynamically, slab sides can create predictable airflow behavior and pressure distribution, which the host argues can be efficient depending on the overall shape.

The BMW 328 Mille Miglia is a classic BMW race car associated with the Mille Miglia road-racing event. It’s notable here because it uses an enclosed, streamlined body shape while still having pronounced slab-like body sides, which affects airflow and drag.

High and low pressure spots are regions on a body where airflow creates different static pressure levels, strongly influencing drag and lift. The host describes using yarn to visualize the flow so they could see where pressure changes occur and then correct the shape with the canopy.

A ladder frame is a body-on-frame style chassis made from two long rails connected by crossmembers, resembling a ladder. It’s commonly used in trucks and some classic builds because it’s strong and straightforward to fabricate, and the host is comparing it to tube-frame construction.

A tube frame is a chassis built from welded metal tubes, typically forming a rigid space-frame-like structure. Compared with ladder frames, tube frames are often lighter and can be tuned for stiffness and packaging, which matters when widening a chassis and reworking suspension mounting points.

Bulkheads are structural panels or internal walls used to add rigidity and to separate sections of a vehicle. The host mentions transverse bulkheads (across the car) and longitudinal ones (along the car) that tie into the frame, helping the chassis resist flex.

SCCA stands for Sports Car Club of America, a major U.S. motorsports organization that runs club racing and autocross events. When someone builds a car “for SCCA,” they typically mean it’s set up to meet the safety and rules requirements for those events.

“VW two piece case” refers to an older Volkswagen engine crankcase design made in two halves. The speaker is using it to identify a specific vintage engine architecture used for their land-speed/record setup.

A camshaft “grind” like “Iski 2J” identifies a specific aftermarket cam profile that changes valve timing and lift. That directly affects how the engine breathes at different RPMs, which matters for record attempts and racing.

Ocrasa heads are air-cooled Volkswagen cylinder heads associated with performance and racing history. The speaker emphasizes their rarity and notes they’re used here as “dual port” heads for a specific early VW engine case.

“Dual port” describes an intake design where the cylinder head has two separate intake ports per cylinder (instead of a single port). This typically improves airflow and tuning flexibility, especially for performance builds.

“36 horsepower case” refers to an early Volkswagen engine crankcase/engine family commonly identified by its original factory rating. The speaker is saying the dual-port Ocrasa heads were made to fit that specific case generation.

A flow bench is a test device used to measure how well cylinder heads and intake/exhaust components move air. Builders use it to compare setups and optimize port shapes for better breathing, which can improve power.

Land speed records are speed benchmarks set by vehicles over measured distances on land, typically emphasizing sustained top speed and stability. The speaker connects the engine/airflow work (heads, intakes) to achieving those record results.

A gearbox is the transmission’s gear-changing unit that selects different gear ratios to match engine speed to driving conditions. In performance builds, the gearbox choice affects how the engine’s power is delivered and how the car behaves under acceleration and at speed.

The Porsche 356 is an early Porsche sports car known for its lightweight, air-cooled flat-four engine and classic 1950s–60s design. In this episode, it’s specifically referenced as the engine model the guest built and had other builders create, tying the conversation to period-correct engine building for a 356.

Engine builders are specialists who assemble, machine, and tune internal engine components to achieve a target performance and reliability goal. For classic cars like the Porsche 356, engine-building expertise matters because small changes in parts and clearances can strongly affect output and durability.

A four-cam engine uses two camshafts per cylinder bank (or four total camshafts) to operate the valves, typically allowing more precise valve timing and higher potential performance. In the context of classic racing-era builds, it’s a notable performance architecture compared with simpler cam setups.

“36 horse” refers to an early engine’s approximate horsepower rating (horsepower is the engine’s power output). Swapping to a lower-power “36 horse” engine in a land-speed context highlights how builders may prioritize reliability, gearing, and drivability over peak power.

A pushrod valvetrain uses pushrods to transfer motion from the camshaft to the rocker arms that open the valves. It’s a common, durable layout in many engines, and in this episode it’s used to describe the character of the “36 horse” setup.

Jay Leno’s is a well-known U.S. car-related media venue where collectors and builders often bring interesting vehicles. In this episode, it’s mentioned as a place the guest took Tom before he slowed down, connecting the engine-building story to the broader classic-car community.

The Land Speed Racing Hall of Fame is an honor recognizing people who have made significant contributions to land-speed racing. It’s specifically tied to record-setting attempts on land (not road courses), where engine design and stability at extreme speeds matter a lot.

Counterweighted means adding mass in a specific place to balance an engine’s rotating forces. In this story, the “unused” bank is counterweighted so the engine can still run smoothly enough for land-speed work.

CNC milling is a machining process where a computer controls a rotating cutting tool to remove material with high precision. The speaker mentions a friend who does CNC milling for small exterior components like door handles and badges.

Coachbuilding (often described as “coach built”) is the traditional practice of constructing or customizing a car’s body, frequently in small numbers. It’s associated with hand finishing, bespoke panel shapes, and visible fabrication details like welds and tool marks.

Tool marks are visible impressions left by fabrication tools on metal surfaces. In hand-finished or coachbuilt work, enthusiasts may notice them as evidence of the manual process, even though builders often try to minimize them for a cleaner final finish.

Welds are joints created by fusing metal together, typically during body fabrication. In custom builds, weld visibility can be part of what the speaker calls “hand finished nature,” though many builders later refine surfaces for a smoother appearance.

A tube buck is a physical framework (often made from tubing) used as a shaping form for body panels. In coachbuilding and custom fabrication, it helps the builder create accurate curves and “deep draws” so the metal ends up with the intended shape.

“Deep draws” refers to forming metal into a deeper, more pronounced shape during panel fabrication. The deeper the draw, the more difficult it can be to keep the panel accurate without issues like stretching or distortion.

In sheet-metal forming, “reverses” are changes in direction/curvature within a panel shape that can complicate forming. They often require careful tooling and technique because the metal has to transition smoothly where the geometry “turns back” on itself.

Gull-wing doors are hinged at the roofline and swing upward, creating a distinctive “wing” motion. They’re often associated with sports cars and can improve access while also influencing how the roof and body structure are designed.

In automotive body design, the “greenhouse” is the glass cabin area—windshield, side glass, and rear glass—plus the surrounding roof structure. It strongly affects visibility, occupant space, and the overall silhouette of the car.

“Fresh air vents” here refers to manually controlled ventilation openings that can be opened to bring outside air into the cabin. The host uses them as an example of how they solved heat and stuffiness issues in a coupe.

“Air conditioning” (AC) is used here as a practical solution to cabin heat in a coupe. The speaker gives specific operating conditions—AC blowing at 34°F when it’s 85–87°F outside—to show how effective the system is even under track use.

Wheelbase is the distance between the front and rear axles, and it strongly affects packaging, stability, and how “tight” a car can feel. Here, the builder discusses an ideal wheelbase for Porsche-based builds, stating they’ve landed on ~94 inches for a four-cylinder mid-engine layout.

Track width is the distance between the left and right wheels on the same axle. Wider track width generally improves lateral stability and reduces how easily the car feels like it’s “leaning” in corners.

Weight distribution describes how much of the car’s mass sits on the front vs. rear (and sometimes left vs. right). It’s a key driver of handling balance—how predictable the car feels under braking, acceleration, and cornering.

A service panel is an access door or removable section that lets a technician reach components for inspection, maintenance, or repairs. In complex cars—especially mid-engine designs—service panels are part of the “design for usability” that reduces downtime and frustration.

The master cylinder reservoir is the fluid tank that feeds brake fluid to the master cylinder. When you open the reservoir, you can check fluid level and top up without disassembling major brake components.

A remote reservoir is a brake-fluid (or sometimes clutch-fluid) container mounted away from the master cylinder. It’s used to make servicing easier or to package the system better in tight engine bays.

The BMW 535i is a 5 Series model where under-hood packaging can make even basic repairs more labor-intensive. In this story, a valve cover gasket job turns into a bigger job because of wiring and fuel-injection components that must be moved.

A valve cover gasket seals the valve cover to prevent oil from leaking out. If it fails, oil can seep onto surrounding components, and the repair may require removing nearby parts to access the gasket.

The fuel injection rail is the pressurized fuel distribution line that supplies fuel injectors. On some engines, accessing the valve cover area requires moving components near the rail, which increases labor and complexity.

The Subaru R2 is a small kei-class car from Subaru, notable for its compact packaging and the way it was engineered for city use. The podcast specifically highlights it in a discussion about electronics and mentions it as having a “flat six powered” setup, framing it as a kind of unusual, spaceship-like configuration. That’s why it stands out in a conversation about mechanical and tech choices.

ITBs stands for individual throttle bodies. Instead of one throttle plate feeding the whole engine, each cylinder (or cylinder pair) gets its own throttle, which can improve throttle response and airflow control.

MoTeX management refers to an aftermarket engine management system (ECU/software) used to control fuel injection, ignition timing, and other parameters. It’s often used when building or modifying engines because it allows deeper tuning than factory systems.

ECU means Engine Control Unit, the car’s main computer for engine operation. Modern ECUs can be configured to adjust many internal parameters, including ones that would be difficult or impossible to change on simpler factory setups.

The Polo 911-4 is a custom four-cylinder engine build derived from a Porsche 911 six-cylinder architecture. The idea is to remove the two center cylinders and shorten the engine case so it can run as a compact, robust “four-cylinder 911” style powerplant.

Dean Pilopoulos is the builder mentioned who developed the Polo 911-4 concept. In this episode, he’s credited with taking the Porsche 911 six-cylinder “down to four cylinders” idea and turning it into a repeatable business.

Chuck Beck is mentioned as one of the people who worked on converting a Porsche 911 six-cylinder engine into a four-cylinder by removing the two center cylinders. The episode says he built a couple of examples but didn’t pursue it further, while Dean Pilopoulos continued the work.

“Twin plug” means the engine uses two spark plugs per cylinder instead of one. That can improve combustion consistency and help the engine make more power or rev more freely, especially at high RPM.

To “turbocharge” an engine means using a turbocharger to force more air into the cylinders. More air (with the right fuel) generally allows more power, but it also changes heat, stress, and tuning requirements.

“RPM” (revolutions per minute) is a measure of engine speed, and “crazy RPMs” implies the engine is designed to spin far higher than typical street engines. High-RPM operation increases demands on valve springs, lubrication, and rotating assembly strength.

A “cam chest” is the housing/structure that contains the camshafts and their oiling passages in certain engine designs. It’s a critical part of the valvetrain because it supports cam timing components and helps manage lubrication.

“Cylinder heads” are the castings that sit on top of the engine block and contain the combustion chambers, intake/exhaust ports, and valve mechanisms. For a performance build, head design directly affects airflow and combustion, which is why custom heads are often a major part of high-RPM engines.

“Top end” refers to the upper portion of an engine—typically the cylinder heads and valvetrain components. When builders talk about modifying the top end, they usually mean changing airflow, valve timing, and combustion efficiency to support higher RPM and power.

“Flat fans” is likely a shorthand for a specific cooling-fan or ducting setup used on race cars, but the transcript doesn’t provide enough detail to confirm the exact component. In context, it’s tied to a 935-related setup and is described as being used on 911 race cars.

Swindon Powertrain is referenced as the UK partner supplying the powertrain they’re working with. The host credits the company’s shop output as part of getting the engine package running.

Richard Tuttle is mentioned as the person behind the UK shop work associated with Swindon Powertrain. The host calls his output “amazing” and a personal inspiration.

“Four cam 32 valve” describes the valvetrain layout: four camshafts controlling 32 valves total. More valves and cam control can help the engine breathe better at high RPM, which matches the episode’s focus on peak power at very high revs.

“Peak power at 8600 RPM” means the engine’s maximum power output occurs when the crankshaft is spinning at 8,600 revolutions per minute. High-RPM peak power usually implies an engine designed for revving hard rather than low-end torque.

“Red line” is the engine’s maximum recommended RPM range, beyond which continued operation can risk damage. The episode uses it alongside “over rev limit” to describe how aggressively they’re targeting RPM capability.

“Over rev limit” means spinning the engine beyond its programmed or engineered RPM ceiling. The episode frames this as a target capability (10,000 RPM) beyond the stated red line, which implies careful valvetrain and rotating assembly design.

Bill Rader is credited with rebuilding and re-gearing the transaxle for the flat-eight setup. That kind of work is crucial because gear ratios determine how the engine’s powerband translates into acceleration and drivability.

A “transaxle” combines the transmission and differential into one unit, often used to improve weight distribution and packaging. Here, it’s described as the unit that will go with the flat eight and has been rebuilt and re-geared for the build.

TJ Russell is referenced as the builder who ran the redesigned chassis through FEA testing and provided feedback. The host also ties Russell to Baja 911s, implying experience with high-stress, off-road Porsche builds.

“Baja 911s” refers to Porsche 911s built for off-road racing and rugged use, inspired by the Baja-style desert environment. The term signals a chassis and drivetrain setup that prioritizes durability, cooling, and traction over pure street comfort.

FEA testing (finite element analysis) is a computer simulation method used to predict how parts will flex and stress under load. In this episode, it’s used to evaluate chassis behavior and to validate custom uprights before building confidence in real-world performance.

“CNC milled uprights” refers to suspension upright components machined using CNC (computer numerical control) equipment for precise shapes and tolerances. The episode emphasizes that these uprights were custom-made and then validated with FEA.

“Case halves” are the split sections of an engine’s housing (often the crankcase) that are machined and assembled together. The episode mentions the first casting of the case halves and then machining the crank, highlighting the engine’s build stages.

Drum brakes use brake shoes that press outward against a drum to create friction. The host discusses “period drums” and “356 drums,” implying an older, historically correct brake choice versus later disc brake conversions.

A disc brake uses a rotating disc and friction pads to slow the vehicle, typically offering strong, consistent braking and better heat management than drum brakes. The host contrasts disc brake setups with period drum brakes for early cars.

CSP is referenced as a German company that makes a disc brake kit used on most of the host’s cars. The host highlights the kit’s fitment (including the wide five bolt pattern) and claims it’s reliable and well-finished.

A wide five bolt pattern is a wheel mounting layout with five lug bolts spaced on a larger diameter than some other common patterns. It matters for fitment because wheels and hubs must match the exact bolt pattern.

In restoration context, “reproduction” parts are newly made components intended to match the original design. The host notes you can buy brand-new reproduction Porsche components, but they often restore existing parts instead.

Swing axles are a rear suspension design where each wheel is attached to a pivoting arm that swings up and down. This layout can create distinctive handling traits, and in this segment it’s paired with a pushrod system and coil-over to achieve the “zero roll” behavior.

“Zero roll” describes a suspension geometry goal where the car resists body roll during cornering. The idea is to keep the chassis flatter by using the suspension’s linkage and motion ratios to counteract the roll tendency.
