Dan Binks - 3 Cylinder Monster

A three-cylinder engine uses three combustion chambers instead of the more common four or six. In this episode, the host is setting up a specific build: a three-cylinder midget engine designed to make power efficiently for racing.

“Billet” refers to machining parts from a solid block of metal rather than casting or using a cheaper formed blank. In performance engines, billet components are often used to improve strength and consistency for high-stress builds.

The Chili Bowl is a well-known short-track racing event where lightweight, fast engine packages are especially valuable. The episode uses it as the benchmark for why the engine is built without a conventional cooling system.

Oil cooling uses engine oil as the primary heat-transfer medium instead of relying on a conventional liquid coolant radiator. This build is described as having no radiator and no water pump, with the oil doing the cooling work for the race environment.

A conventional cooling system uses a radiator, water pump, hoses, and coolant to control engine temperature. Removing those components reduces weight and complexity, but it requires an alternate strategy—here, oil cooling and a race-specific setup.

In racing, “alcohol” fuel typically refers to alcohol-based blends (often methanol or similar) that can offer strong performance characteristics. The episode ties alcohol use to the engine’s cooling and fuel system strategy for the Chili Bowl.

“Fuel stacking” is a racing/engine tuning issue where fuel continues to accumulate in the intake/exhaust system or combustion process, often leading to poor combustion and drivability problems. The speaker claims this engine avoids fuel-stacking problems with its setup.

Mechanical fuel injection is a fuel-delivery system that meters fuel using mechanical components (rather than an electronic control unit). It’s often used in racing because it can respond quickly and can be tuned for specific engine setups.

An intake valve is the valve that opens to let the air/fuel mixture enter the combustion chamber. Bigger or higher-flow intake valves can improve breathing, which matters a lot when you’re targeting very high RPM.

An exhaust valve is the valve that opens to let burned gases leave the combustion chamber. Exhaust flow is critical for high-RPM engines because it affects how well the engine can clear gases and take in fresh charge.

Bore is the cylinder’s diameter. In engine specs, bore strongly affects how much air/fuel the cylinder can hold and how the engine breathes at high RPM.

Stroke is the distance the piston travels inside the cylinder. Together with bore, stroke helps determine engine displacement and the engine’s character—especially how it performs at different RPM ranges.

A rev limiter is an engine control feature that prevents the engine from spinning faster than a set RPM. In this build, the speaker says there’s no rev limiter at the Chili Bowl, which is why they can push to around 9,800 RPM outdoors (and only 8,700 RPM in another context).

“Cubic inches per hole” is a way of expressing displacement per cylinder. When the speaker says it’s 55 cubic inches per hole, they’re emphasizing the huge cylinder size for a three-cylinder engine—meaning each cylinder is doing a lot of work.

The speaker links large displacement per cylinder to the need for lots of airflow and high-RPM operation. In practice, that means the engine needs valve area/port flow and timing that can move enough air fast enough at extreme revs.

In engineering, a “clean sheet of paper” approach means starting a design from scratch instead of modifying an existing engine. In this context, it’s about designing a new engine package and manufacturing plan rather than iterating on the previous builds that “had problems.”

The segment contrasts older production constraints with modern manufacturing methods that make tight schedules feasible. The discussion ties this to CNC machining and the ability to source/produce precision engine components quickly.

CNC (computer numerical control) is machining done with computer-controlled tools that cut parts to precise dimensions. The host connects CNC to modern manufacturing capability—like getting crankshafts, rods, pistons, and rings made on a tight schedule.

A crankshaft converts the pistons’ up-and-down motion into rotational motion for the drivetrain. It’s a critical precision part, and the episode highlights lead times for sourcing or machining it.

Pistons are the engine components that move inside the cylinders and transfer combustion pressure to the crankshaft. The segment also mentions “Molly pistons,” implying a specific piston material/coating choice for durability and friction control.

A dry-sump lubrication system uses a pump to pull oil from the engine and store it in a separate reservoir. Dry sump setups help prevent oil starvation during hard cornering and high-RPM operation, and they can support more consistent oil pressure.

“OE” means original equipment—the parts the manufacturer designed and installed on the car when it was built. In performance builds, builders compare their custom parts to OE components to show improvements in strength, durability, or consistency.

RPM (revolutions per minute) is how fast the engine’s crankshaft spins. When someone says an engine needs to do 10,000 RPM, they’re talking about surviving very high rotational speeds where valve control, lubrication, and internal clearances become critical.

Valve springs are rated by the force they provide, often expressed in pounds per square inch (PSI) or related force specs depending on context. Higher spring force helps keep the valves from floating at high RPM, maintaining proper timing and preventing valve-to-piston contact.

Compression releases are devices that temporarily reduce effective compression during engine cranking. They let a high-compression engine spin over more easily so it can start, then they disengage once the engine is running.

A push start (also called bump starting) starts a vehicle by rolling it and engaging the drivetrain so the engine turns over mechanically. It’s sometimes used when an engine is hard to crank—like a high-compression build—so the vehicle’s motion helps get the engine spinning.

The speaker is referencing Harley-Davidson parts being repurposed for this engine build. It highlights how builders sometimes borrow proven components from other platforms when they solve a specific problem—here, starting a high-compression setup.

“Unlimited” in this context refers to a racing format where the rules allow a very broad range of engine and build approaches, so teams can push unusual designs. It’s used to describe the spirit of the event rather than a specific engine spec.

Piston rings seal the gap between the piston and cylinder wall to control compression and manage oil. In racing builds, ring choice and availability can be a major constraint because they directly affect sealing, friction, and engine durability.

“027” is a ring specification (commonly referring to ring thickness or a dimensional code used by the manufacturer) that determines how the ring fits and seals in the engine. Using a specific ring spec matters because it affects sealing performance and how much margin you have if parts are scarce.

The speaker is describing a multi-engine setup where multiple engines (three) are built to collectively create a very large total cylinder count (33). This kind of packaging is typically done for specialized racing experiments where the goal is to test or extract power from an unusual configuration.

“LS main bearings” refers to the main bearings used in GM’s LS V8 engine family. Main bearings support the crankshaft in the engine block, and using LS-spec bearings is a common way builders standardize parts when adapting components.

“Small block Chevy rod bearings” are the connecting-rod bearings used in Chevrolet’s small-block V8 engines. Rod bearings sit on the connecting rods and support the crankshaft at each cylinder, so choosing a known bearing design matters when an engine is built to handle high load.

A dyno (dynamometer) is a test stand that measures engine output—typically horsepower and torque—under controlled conditions. Builders use it to verify the engine runs correctly and to diagnose issues before putting the car into real-world driving.

“Coils” are the ignition coils that transform battery voltage into the high voltage needed to fire the spark plugs. If coil grounding is incorrect, the coil may not energize properly, causing misfires or poor running until the wiring/grounding is fixed.

In this context, “ignition” refers to the system that fires the spark plugs at the right time to ignite the air-fuel mixture. The transcript links ignition issues to coil grounding and electrical resistance, which can directly affect combustion stability.

The transcript describes how electrical resistance in the engine block can interfere with grounding. When current returns through a resistive path, components on opposite sides of the block can see different voltages, which can disrupt ignition electronics and cause the engine to run poorly.

Grounding problems happen when an electrical system doesn’t have a proper low-resistance path to chassis/engine ground. In ignition systems, poor grounding can cause incorrect coil/ignition behavior, leading to misfires or unstable running—especially when the wiring is routed or grounded through the engine block.

“Grounding through the block” means using the engine block itself as part of the electrical ground path. Because the block material and interfaces have resistance, this can create voltage differences between components (like coils and the ignition electronics), which can make the engine run badly until the grounding strategy is corrected.

A wiring harness is the bundled set of wires and connectors that routes power and signals through the vehicle. In performance builds, the harness design and grounding scheme can be critical—changing how grounds are handled can eliminate ignition/ECU problems.

Here, “AI” is being used as a troubleshooting and tuning assistant: the host inputs symptoms or questions and the system returns suggestions. In practice, it can help narrow down possibilities, but it still needs verification because it’s not a substitute for proper diagnostics.

In an engine, ignition timing is when the spark happens relative to piston position. Changing timing can make the engine respond better (like being less “sluggish” off the corner) but too much can cause knock and damage.

The cylinder head is the top part of an engine that houses key components like the combustion chamber surfaces and the valves. When the speaker mentions “cylinder head problems” and needing cast cylinder heads, they’re pointing to manufacturing/strength issues that can affect durability under high load.

Pike’s Peak is a famous hill climb in Colorado that reaches high elevation, where the air is thinner. That makes turbo boost and engine airflow management especially important for maintaining power as altitude increases.

Boost is the extra air pressure a turbocharger (or supercharger) adds above normal atmospheric pressure. Higher boost generally means more potential power, but it also increases stress on the engine and requires careful tuning and cooling.

A flat-six is an engine layout where six cylinders sit horizontally in two banks of three on opposite sides of the crankshaft. The speaker’s point is that their three-cylinder-per-side concept resembles a flat-six’s packaging, which can influence balance, cooling, and how power is distributed.

“Power per cubic inch” is a specific-output metric that relates engine power to displacement (how much volume the engine displaces). Higher power per cubic inch usually means the engine is extracting more performance from each unit of size, often requiring aggressive airflow, boost, and tuning.

Going from a multi-cylinder engine to a three-cylinder changes the engine’s balance, packaging, and how much hardware you have to service. Fewer cylinders can reduce weight and complexity, and it can make certain maintenance tasks faster—especially in racing or prototype builds.

The speaker is describing a replaceable cylinder-sleeve design where the sleeves can be removed and replaced without replacing the whole engine block. This is often used in performance or racing engines to make repairs faster and cheaper after wear or damage.

Rockers and pushrods are part of a pushrod valve-train system that transfers motion from the camshaft to the engine’s valves. Adjusting them ensures correct valve timing and lift, which affects performance and can prevent valve-train wear.

A “single turbo V6” means a V6 engine (six cylinders arranged in a V shape) using one turbocharger to force more air into the engine. With enough supporting mods and tuning, a single-turbo V6 can produce very high power—here, the host says it makes over a thousand horsepower.

Weight balance is how much of a car’s mass sits toward the front vs. the rear (and left vs. right). The host connects it to engine choice—imagining a “200 pound three cylinder turbo” making huge power—because changing engine weight and placement can strongly affect handling and traction.

Calling the cars “pipe bombs” is enthusiast shorthand for engines that were extremely loud and/or aggressive, often with minimal emissions equipment and a lot of exhaust flow. The host contrasts that with modern evolution of parts and electronics that make the same kind of power more controllable and durable.

No lift shift is a driving technique where the driver keeps the throttle open during an upshift instead of lifting off the gas. On race cars, it’s often supported by engine management so the car can maintain boost and reduce the power interruption that would otherwise slow acceleration.

Traction control is an electronic system that detects wheel slip and intervenes—typically by reducing engine torque—to regain grip. In a high-power race car, it helps prevent the drive wheels from spinning, especially during hard acceleration or low-grip conditions.

Knock sensors detect “knock,” an abnormal combustion event that can damage an engine. When knock is detected, the ECU can adjust ignition timing and other parameters to protect the engine—here, the host says it “won’t let it detonate” and can take timing out if it gets hot.

Detonation is uncontrolled, explosive combustion that occurs when the air-fuel mixture ignites too aggressively or at the wrong time. It’s dangerous because it can rapidly increase cylinder pressure and lead to engine damage, so performance ECUs use sensors and timing adjustments to prevent it.

This segment discusses why Cadillac’s involvement in sports car racing surprised some people. It frames the brand’s racing participation as a departure from the “big boats” stereotype.

General Motors (GM) is the automaker behind brands like Cadillac, and the host frames it as having a long racing and engineering footprint. Here, GM is discussed as a platform for funding and staffing the effort to compete in top-level motorsport.

The segment claims that Cadillac/GM is making its own Formula One engine. That matters because Formula One engines are highly specialized, with strict technical rules and intense development timelines.

IMSA refers to the International Motor Sports Association, which runs major North American sports-car racing series. The host’s mention of “fast Imsa cars” connects GM/Cadillac’s development efforts to endurance-style racing demands, not just street performance.

The speaker is talking about the Miami Formula One event and why it stands out. They mention the venue setup and how the stadium location affects the race experience.

Titanium nitride (TiN) is a hard ceramic coating used on engine parts to resist wear and reduce friction. In this context, it’s being discussed as a durable surface treatment that performs well even when small amounts of dirt get through.

The speaker is referring to a coating thickness of 0.7 millimeters, which matters because thinner coatings can be better suited to tight packaging on small engine components. Here it’s tied to “thin ring packs,” implying the coating thickness is chosen to fit the available space without compromising durability.

A ring pack is the set of piston rings on an engine piston. Its thickness and design affect sealing and how much room there is for coatings or other treatments, which is why the speaker connects coating thickness to “thin ring packs.”

The speaker notes the coating is also used in Corvette pistons, tying the technology to a performance-focused Chevrolet model line. That matters because Corvette engines are often tuned for higher stress, so the coating’s wear resistance is part of the pitch.

A dome piston has a raised “dome” on top of the piston crown, which changes the combustion chamber shape. That can influence compression characteristics and how the air-fuel mixture burns, which is why piston crown shape is often chosen carefully for specific engine setups.

Compression ratio is the ratio between the volume in the cylinder when the piston is at the bottom versus at the top. Higher compression generally improves efficiency and power, but it also increases the risk of knock/detonation if the fuel and calibration aren’t right.

An oil ring is the piston ring specifically designed to scrape excess oil off the cylinder wall and return it to the crankcase. Thinner oil rings can reduce friction, but they must still maintain effective oil control under high loads and temperatures.

Detonation is uncontrolled, near-instant combustion that can occur when the end-gas in the cylinder auto-ignites under high pressure/temperature. It’s harmful because it creates extreme pressure spikes that can overheat components and damage the engine.

The Subaru 360 is a small, early compact car from Subaru that’s often remembered for its lightweight design and simple, economical approach. In the podcast context, it’s mentioned as a “360” that was used in a pavement car and involved in a sudden spin-out, which points to how these cars can behave under real driving conditions. It’s discussed because it’s a recognizable piece of Subaru’s history and a classic example of compact-car engineering.

A “cast head” refers to an engine cylinder head made by casting molten metal into a mold. Cylinder heads are critical because they shape the combustion chambers and house the valvetrain, so casting choices affect strength, cooling passages, and how easily the head can be modified for racing rules.

“COMP Eliminator Race” refers to a specific drag-racing class format where cars compete under rules that constrain engine and vehicle modifications. The mention implies the engine/head work is being done to stay within those class legality requirements while maximizing speed.

A drag car is built and tuned specifically for straight-line acceleration over a short race distance. These cars often emphasize weight reduction and traction to convert engine power into rapid launches and consistent passes.

HRA here refers to a drag-racing sanctioning/competition organization that sets class rules. When the host says the cylinder head would be legal for an HRA, they mean it would comply with that organization’s technical regulations.

A lightweight dragster is a drag-racing car designed to minimize mass so it accelerates faster for a given amount of power. In drag racing, lower weight improves acceleration and helps the car launch and stay controllable under hard traction demands.

Horsepower is a measure of engine power output, reflecting how much work the engine can do over time. In drag racing discussions, horsepower is often paired with vehicle weight to estimate how quickly a car can accelerate.

Vehicle weight is a key factor in acceleration because it determines how much mass the engine has to move. In drag racing, extremely low weight can make even moderate power feel very fast.

A 3-cylinder engine uses three combustion chambers instead of the more common four or six. With fewer cylinders, it can be smaller and lighter, which helps packaging, but it also changes how smooth the power delivery feels and how the engine is balanced.

The episode framing (“3-cylinder monster”) points to the idea that a small-displacement engine can still feel extremely powerful. With the right setup—often including turbocharging—three-cylinder engines can produce strong torque and sound lively under load.

A rally car is built for off-road, mixed-surface stages and is tuned for rapid throttle response and traction management. That “mountain of power” comment implies the same small-engine/turbo idea can work in demanding rally conditions.

Stationary engines are engines that don’t move with the vehicle; they run in fixed locations for power generation or industrial use. “Stationary engine parts” refers to components made for those applications rather than automotive engines.
