Pancho Weaver on Nascar Chassis, Building a Trans AM Monster and a Career in Racing
Brand

6XD Gearbox

They’re the sponsor here, and the name suggests they make or support gearbox/transmission parts. It’s worth checking them out because sponsors like this usually have something performance-related to offer.

Topic

Road America

Road America is a well-known road course in the U.S., and it’s used here as the setting for discovering Pancho Weaver. For listeners, it helps to know that this is the kind of venue where serious racing cars and fabrication work show up.

Brand

Parnelli Jones

Parnelli Jones was a famous race driver. The host is using him as an example of the kind of big-name racing culture that was around Weaver’s family.

Brand

Dan Gurney

Dan Gurney is named alongside other legendary drivers, reinforcing that Weaver’s father was connected to top-tier racing figures. This helps listeners place the story in a historical motorsports network rather than a casual local scene.

Brand

Carol Shelby

Carol Shelby was a legendary figure in American racing and performance cars. Mentioning him suggests Weaver’s dad was connected to influential people who shaped how race cars are built.

Concept

TransM class

They’re referring to the Trans Am racing class. It’s a set of rules for what kinds of cars can race and what safety equipment they must have, but it still leaves room for teams to build and improve their cars.

Topic

innovation is welcome in this class

They’re talking about whether racing rules allow teams to experiment. The point is: some series are very strict, but this one is described as more open to new ideas.

Concept

safety standards and rules

Even when racing allows creativity, there are rules meant to keep people safe. Those rules usually cover how the car is built and what safety gear it must have.

Concept

cookie cutter kind of class

They mean a racing series where everyone builds the same kind of car. Here, they’re saying Trans Am isn’t like that—it lets teams try different approaches.

Concept

technology helps drive all that

They’re saying racing gets better as technology improves. Better brakes, engines, tires, and aerodynamics all help the car go faster and handle better.

3 Three Wheeler
Car

3 Three Wheeler

A three-wheeler is a vehicle that has three wheels instead of four. Because it has fewer wheels, it can handle and feel different than a normal car. The podcast is likely setting up a deeper explanation of how it works or why it’s notable.

Concept

Road race, GT1 type class car

“GT1 type” is shorthand for a high-performance grand touring-style race category. In practice, it usually implies a focus on aerodynamic efficiency, cooling capacity, and chassis setup to handle sustained cornering speeds—more like endurance/GT racing than short sprint touring-car racing.

Concept

chassis program

A chassis program is the development effort focused on the race car’s structure and dynamics—things like frame design, suspension geometry, stiffness, and how the car transfers loads. In racing, the chassis is often the foundation that determines how well the engine and aero can actually perform on track.

Concept

generation three weaver

“Generation three” indicates an iterative design evolution—major updates to the race car’s architecture and/or systems compared with earlier versions. Calling it a “Weaver” generation suggests the guest’s own development lineage and a structured approach to improving performance and integration over time.

Concept

cost about $100,000 less than the competitors

He’s talking about building a race car for less money than other teams. In racing, spending less can mean smarter design choices so you still get good performance.

Term

sound of the engine

He’s emphasizing that the car should sound impressive. In racing, exhaust and engine tuning can change the noise you hear.

Term

180 degree header system

A header is part of the exhaust that collects gases from the engine and routes them into the rest of the exhaust. A “180 degree” setup means the pipes are shaped to turn gases in a specific way, which can change both performance and the sound you hear.

Concept

tight constraints (for building a race exhaust)

Race parts aren’t just designed on paper—they have to physically fit in the car. “Tight constraints” means there’s very little room or flexibility, so building the part takes more work.

Term

paint scheme

A paint scheme is the specific color layout and graphics pattern used on a race car. In motorsports, it’s part of branding and fan recognition, and it can become “iconic” when repeated across seasons.

Brand

Menard yellow

Menard yellow is a bright yellow color tied to the Menards brand. Race teams often use sponsor colors so people can recognize them quickly.

Brand

STP

STP is a brand that has sponsored racing for a long time. When you see “STP” on a race car, it usually means that company was a sponsor.

Concept

test day (development and learning)

A test day is when a race team goes out to try the car and learn what works. They drive it hard to find problems and improve the car before real races.

Topic

Virginia test day

They mention a test session in Virginia where the team worked on the car. It’s part of the story of how the car was developed.

Concept

all-round tube construction (round tube chassis)

Instead of building the frame from square tubes, they used round tubes. Round tubes usually handle twisting forces better, which helps the car stay more stable under load.

Term

miter joint

A miter joint is a connection where two pieces are cut at angles (like a corner) so they meet at a specific angle before welding. In square-tube frames, frequent angle changes can require more miter joints, which can add weld complexity and potential weak points.

Term

butt weld

A butt weld is when two metal pieces are joined directly end-to-end. More joints can mean more welding work and more places where strength depends on the weld quality.

Term

CNC bend

CNC bending is a machine-controlled way to bend metal tubes very precisely. It lets you make the frame shape without as many cut-and-weld joints.

Term

torsional stiffness

Torsional stiffness is how resistant a chassis is to twisting forces. Higher torsional stiffness generally improves handling consistency because suspension and alignment geometry stay more stable when the car loads up over bumps and during cornering.

Term

sway bars

A sway bar helps keep the car from leaning too much in corners. The host is saying round shapes help the bar resist twisting forces.

Term

coil over shocks

A coil-over is basically a spring and a shock absorber working together. The spring supports the car, and the shock controls how fast the car moves up and down so it stays planted in turns.

Term

sprung through shock

“Sprung” just means the car’s suspension is doing the work of supporting the car. Instead of the tires taking everything, the springs and shocks share the load, especially when you corner.

Term

recoil

Recoil is the car’s bounce-back after it squats or compresses in a turn. If it bounces back too slowly or too much, you have to wait before you can put power down confidently.

Concept

wrap up (chassis)

“Wrap up” is how much the frame flexes when you load it in a corner. If the chassis flexes less, the car usually feels more controlled and you can get on the gas sooner.

Term

chassis twisting

When you turn hard, the car’s frame can twist like a wrench. If it twists too much, the wheels don’t stay in the best position, and the car feels less stable.

Term

rolling up into the corner

This is the car leaning as you start turning. The amount and speed of that lean changes how the tires grip and how the car feels when you turn in.

Term

G load

G load is just how hard the car is being pushed in a direction—like how strong the forces feel when you corner. More cornering G means the suspension and tires are working harder.

Concept

first set / second set (suspension settling)

The “first set” is the car’s initial bounce/settling when you load it in the turn. The “second set” is what happens after it finishes that movement—when the car is ready to hook up and accelerate.

Concept

round tube versus square tube

This is about the shape of the metal tubes in the car’s frame or cage. Different shapes can make the structure stiffer in different ways, which can help the car stay more stable in corners.

Chevrolet Corvette
Car

Chevrolet Corvette

They’re talking about the Chevrolet Corvette. It’s a sports car that many people buy because it’s built for performance and there are lots of parts and upgrades available.

Chevrolet Camaro
Car

Chevrolet Camaro

They’re also talking about the Chevrolet Camaro. It’s a performance car with a big enthusiast following, so it’s common to hear it mentioned alongside other racing-oriented cars.

dodge challengers
Car

dodge challengers

They’re mentioning the Dodge Challenger. It’s a muscle car people like for its power and style, and there are lots of upgrades available.

Term

mechanical grip

Mechanical grip is how well the tires can “grab” the road because of the car’s suspension and how it loads the tires. It’s the kind of grip you feel when the car sticks through turns even without downforce.

Term

steering rack

The steering rack is the mechanism that turns your steering wheel into the wheels turning left or right. Where it sits in the car matters because it can affect how the car behaves over bumps.

Term

uprights

Uprights are parts near the wheel that help connect the suspension to the wheel. Their position affects how the wheel moves and how the steering feels.

Term

bump steer

Bump steer is when hitting bumps makes the steering wheel turn by itself. Good suspension design keeps that from happening so the car stays predictable.

Concept

knife edge

“Knife edge” is a driving/handling concept describing a car balanced right at the limit of grip. When a car is on the knife edge, small inputs or disturbances can cause it to lose the line, so the driver and chassis must manage stability precisely.

Term

sequential transmissions

A sequential transmission means you shift up or down in order, like a step-by-step gearbox. Race cars like it because it can make shifting quicker and more consistent when you’re driving hard.

Term

FD field

“FD” is Formula Drift, a major drifting competition. Saying the “FD field” uses a certain gearbox is basically saying it’s common among drivers who really beat on their cars.

Term

CAD

CAD is a computer program for designing parts. Instead of guessing, you can test fitment virtually to make sure things clear and don’t hit when the car moves.

Term

center of gravity

Your car’s center of gravity is basically where the weight “balances.” If you lower it, the car tends to feel more stable and less likely to tip around in corners.

Term

ballast

Ballast is extra weight you add on purpose. Racers use it to meet rules or to help the car handle better by putting the weight in the right spot.

Term

14 inches of rear rubber

They’re talking about how wide the tires are. Wider tires usually grip the road better, but the car still has to be set up correctly so it doesn’t spin or slide.

Term

aero

Aero is how the car’s shape interacts with the air. The right aero setup can push the car down onto the tires for better grip and faster cornering.

Term

two inches off the ground

That’s how low the race car sits to the track. Sitting lower can help the car stick better, but if it’s too low it can hit the ground.

Term

900 horsepower

Horsepower is how strong the engine is. More horsepower can help you go faster, but you still need enough tire grip to use it effectively.

Term

600 foot pounds of torque

Torque is the engine’s pulling strength. It helps the car accelerate, but if it’s too much for the tires, the car can lose grip.

Concept

tame the monster

A race car can have so much power and grip that it feels hard to control. The goal is to drive smoothly so the tires keep traction and the car doesn’t get loose or slow you down.

Concept

driver coaching area and a car coaching area

They’re saying this series is like a training ground. Drivers learn how to handle the car better, and teams learn how to set the car up so it performs more consistently.

Concept

proven grounds

They mean this is a proving/testing place. You learn and improve in real race-like conditions before stepping up to bigger competition.

Topic

Daytona

They’re talking about Daytona as the track where they measured how fast the car is. Different tracks change how the car’s power and grip show up.

Term

NASCAR engine

They’re talking about the engine rules for NASCAR. This class allows older NASCAR-style engines, which affects how the car makes power and how teams tune it.

Concept

NASCAR Cup cars

In NASCAR, the “Cup” level is the top, most competitive series. The speaker is saying the engine tech they’re using traces back to that top-level Dodge racing program.

Company

Penske

Penske is a well-known NASCAR team. They also help with race-engine programs, so the engines mentioned here are tied to their Dodge racing history.

Term

R6 Dodge design

R6 is a newer allowed version of the race engine. When rules let you use a newer version, it can change how the car performs and how teams set up the rest of the program.

Term

R5

“R5” refers to a specific iteration of a NASCAR engine design used under the rules at the time. The speaker contrasts it with “R6,” implying a newer/allowed configuration within their Dodge NASCAR program.

Term

Sebring

Sebring refers to the Sebring International Raceway in Florida, a famous endurance/road-racing venue. The speaker uses it as a reference point for a driver’s performance, indicating the driver has succeeded in high-profile road-course competition.

Term

points

“Points” are the season-long scoring totals that determine standings in NASCAR. The speaker is using the driver’s points position (third or possibly fourth) to gauge how competitive the program is.

Term

Atlanta race

“Atlanta race” refers to a NASCAR event at Atlanta Motor Speedway, used here as a benchmark for the driver’s points position. Points standings after specific races are a common way teams measure progress.

Concept

driver development program

A driver development program is like a training pipeline for racing talent. Instead of just putting someone in a car, you coach them and give them chances to improve step by step.

Term

road course

A road course is a type of race track with lots of corners, not just left turns on an oval. It usually demands different driving skills, so coaches focus on that style.

Term

saves his tires

“Saving tires” means managing tire wear so the car remains fast later in the race. The speaker credits Boris’s methodical approach—preserving tire grip early to have performance at the end—leading to frequent podiums.

Topic

Trans-Am

Trans-Am is a road-racing series where cars compete under a specific rule set and class structure. The speaker discusses rebuilding the class and growing participation toward a target “car field” size, highlighting how entry counts affect the health of the series.

Topic

Emsa GT type racing

This is about a different kind of racing where “GT” cars compete. The speaker is saying some drivers are coming from that background into Trans-Am.

Concept

car field count

Field count is just how many cars actually show up to race. More cars usually means more competition and a better event overall.

Concept

race smart

Race smart means you don’t just spend money—you make good decisions. With less budget, you focus on the choices that give the biggest payoff.

Concept

build our stuff. We don't buy it.

They’re saying they make their own racing parts instead of buying ready-made ones. That can save money and also let them tailor the car to how they race.

Topic

Baja 1000

The Baja 1000 is one of the most famous off-road desert races in North America, known for long-distance endurance and rough terrain. Mentioning it (along with other Baja events) frames the speaker’s background as endurance-focused off-road racing rather than circuit-only competition.

Topic

Baja 500

The Baja 500 is another big off-road desert race. Like the Baja 1000, it’s about endurance and handling rough terrain.

Concept

Lake Norman

Lake Norman is a big lake near Charlotte, North Carolina. The guest is describing how living there makes it easy to go boating and enjoy the outdoors.

Concept

shop (attached garage/workshop)

They’re talking about a workshop space on the property. For car people, a shop is where you can work on vehicles, store tools, and do projects.

Concept

Barnum Minions

It sounds like a local group or shop nickname. The point is that in racing communities, there are often dedicated crews that help people build and maintain cars.

Concept

TIG welder

A TIG welder is a tool for welding metal very precisely. It’s popular in racing because it makes strong, clean welds for custom parts.

Topic

Formula 1, Formula 5,000, Indy car, midgets, dirt champ cars, drag racing, funny car, and top fuel

The guest lists a wide range of racing categories (open-wheel, dirt, and drag) to illustrate how broad the Parnelli operation was. For listeners, it highlights how skills and engineering approaches can transfer across very different types of racing.

trophy trucks
Car

trophy trucks

Trophy trucks are race trucks built for desert off-road events. They’re made to survive big bumps and jumps while staying fast.

Concept

co-pilot

In off-road desert racing, a co-pilot (or navigator) helps manage pace, route information, and strategy—especially in events where navigation and timing matter as much as driving skill. The role can be critical for avoiding wrong turns and maintaining consistent performance over long distances.

Concept

single-seater

A single-seater is a race car made for just one driver. Building one yourself is a common way racers learn how cars are built and how to make them work.

Topic

Mickey Thompson Stadium series

The Mickey Thompson Stadium series refers to off-road racing events held in stadium-style venues, bringing desert-style vehicles to a more spectator-friendly format. These series helped popularize off-road racing by making it easier to watch and follow.

Topic

1977 Off-Road World Championship Grand Prix

This is a specific off-road race from 1977. The host is basically saying you can look up the footage to see what racing was like back then.

Term

fabrication process

They’re talking about fabrication—how parts get built and put together. The key idea is there isn’t only one “right” way, as long as it works well and looks decent.

Term

no lift shift

No lift shift means you don’t back off the gas when you shift. The car keeps making power through the gear change, so it accelerates harder.

Company

Enthmodo

Enthmodo is mentioned as the group that does the transmission work behind the “6XD” experience. They’re basically associated with the racing tech that lets you shift without lifting off the gas.

Term

reverse lockout

A reverse lockout is a safety/control feature that stops you from accidentally putting the car into reverse. It helps protect the transmission from being shifted into the wrong gear at the wrong time.

Term

four-speed NASCAR transmission

This is a racing-style 4-speed transmission NASCAR used for a while. It’s chosen because it’s cheaper and fits the race car’s layout, not because it’s meant for everyday driving.

Term

dog ring transmission

A dog-ring transmission is a race gearbox that shifts gears with metal “clutches” that lock into place quickly. It doesn’t use the smooth synchronizers you’d find in most street cars.

Term

Gen 7

“Gen 7” refers to NASCAR’s next-generation vehicle/competition rules package that changed how cars are built and what components are used. When he says the dog-ring four-speed was used before Gen 7, he’s pointing to a rules-driven shift in transmission technology.

Concept

turn it on its side, rotate it 90 degrees

Instead of mounting the transmission the usual way, he rotated it so it fits better in the car. That can help with space and handling, but you have to redesign the oiling and shifting so it still works reliably.

Term

oil system

If you rotate a transmission, the oil doesn’t naturally sit where it used to. The oil system has to be redesigned so the gears and bearings still get enough lubrication.

Term

crank centerline

This is a measurement reference point on the engine. He’s using it to explain how close the bottom of the car is to the ground so the car can be low without scraping.

Term

fifth gear

With only four gears, the engine may not stay in the best RPM range as often. Adding a fifth gear can help the car accelerate and maintain speed more effectively.

Term

sequentials

Sequential transmissions let the driver shift through gears in order (typically one gear at a time) rather than using an H-pattern. In racing, sequentials are valued for fast, consistent shifts under load.
