About this episode

Jay from Banks Power walks through how the brand blends marketing with deep engineering—and why it’s obsessed with verified data instead of hype. He shares his path from radio and truck-building to Banks, then zooms out on diesel performance culture: the shift from “delete and chase power” to emissions-compliant, longevity-focused upgrades. Key example: the 6.7L Cummins grid heater failure and Banks’ Monster Ram solution, including optional extra heating elements. The discussion also tackles dyno credibility, OEM-level testing, and why Banks often costs slightly more for measurable results.

Technical Too Afraid to Ask
Company

Banks Power

"Sure. Today, I'm marketing director at Banks Power. I oversee all things marketing, from video content to ad placement, help out with new product development."

Banks Power is a company that makes aftermarket upgrades for diesel trucks. They build performance parts and also work on new products based on what people want.

Term

12 volt

"Prior to that, I ran a car stereo installation company out of my parents garage. So it's been cars and trucks my whole life and or 12 volt, you know, in the audio systems."

Most cars use a 12-volt electrical system. That’s the power level that runs things like the audio system and other accessories.

Company

CBS radio

"So I went to the, the attorney at CBS radio and convinced them to do it."

They’re talking about CBS Radio as the company that had to approve the promotion. Big media brands usually have rules about using their name and logos.

Concept

liability insurance

"And she said the same thing, we'll trust you, but you need to carry $4 million of liability insurance on your own."

Liability insurance helps pay if you accidentally hurt someone or damage their property and you’re found responsible. Big events usually require more coverage because there’s more risk.

Concept

SEMA truck

"I got to know him over the next few years of building this SEMA what turned into a SEMA truck."

SEMA (Specialty Equipment Market Association) is a major U.S. trade show where builders bring highly modified vehicles to showcase aftermarket parts and engineering. Calling it a “SEMA truck” implies the build evolved into a show-worthy, performance/tech-focused project.

Term

turbo diesel

"...there was a banks turbo charged diesel pickup available through dealerships one year prior to the Cummins turbo diesel available in a pickup truck..."

A turbo diesel is a diesel engine equipped with a turbocharger to increase airflow and power. The transcript frames Banks’ system as an early example of turbo-diesel pickups being sold through dealerships before later mainstream offerings.

Term

turbos

"Now look, here we are today, everything has a turbo on but back then it was all about supercharging."

A turbo is a device that uses the engine’s exhaust to spin a fan that pushes extra air into the engine. More air usually means more power.

Term

CNC

"...there's the tube bending shop across the street, CNC, there's the whole thing..."

CNC is a computer-controlled machine that cuts parts very precisely. It helps make components that fit correctly and consistently.

Car

1966 Chevy C20

"...I'm looking at the shop floor and I'm looking at lockjaw, by the way. Lockjaw is our 1966 Chevy C20 on airbags with a supercharged Duramax in it."

A 1966 Chevy C20 is an older Chevrolet pickup truck. The point here is that people take classic trucks and modernize them with newer diesel performance upgrades.

Concept

OEM

"...I can compare it to OEM, compare it to another company's product that might be in that same segment."

OEM means the parts that came from the factory. The speaker is saying you can compare aftermarket products against what the car originally used.

Term

cold air intake

"...I caught one today about a cold air intake system. And that's a whole, you could do a whole show on cold air intakes..."

A cold air intake is a modification that changes how the engine gets air. People debate whether it truly adds big power or just changes sound/feel.

Term

dyno run

"...they may not have what they think is the data to sell their products. So whether they make it up, or they embellish, or they put a dyno run from last September with one from this January on..."

A dyno run is when a car or engine is tested on a machine that measures power. If the test isn’t done the same way each time, the numbers can be misleading.

Term

ambient temperature

"...it should be on the same day or the next day at the same ambient temperature with the same conditions..."

Ambient temperature affects engine performance and dyno readings because air density changes. That’s why dyno tests should be done at the same temperature (or corrected) to compare results accurately.

Concept

real-world towing reliability

"That's what he's looking for. And that's who we, that's who we service. We also, we also will make high horsepower parts occasionally for bragging rights or for to set a record or whatever we've done that Gail has done that, but that's not the market we serve."

The episode frames diesel performance as serving practical needs like towing long distances reliably. That shifts the goal from dyno/YouTube spectacle toward drivability, thermal management, and component life under sustained load.

Term

blow up engines

"I don't like the audience that they've built, you know, for like, it's fun to blow up engines. I'm more of a Gail Banks student that you shouldn't blow up the engine."

“Blow up” means the engine fails badly—sometimes instantly. It usually happens when the truck is pushed harder than the engine can safely handle.

Term

grid heater

"It's called a grid heater because the coil heater looks like a grid when you look at it... And it is sandwiched between the intake elbow, post turbo, post intercooler."

A grid heater is a heating element in the intake system that warms the air when it’s cold outside. On these engines, it helps prevent hard cold starts by preheating the air before it goes into the cylinders. The episode is also about how this heater can be part of a bigger failure problem.

Term

preheat the air on cold winter days

"...and its job is to preheat the air on cold winter days so you don't shock the engine and you get"

In winter, the air entering the engine is very cold. Preheating that air helps the engine burn fuel more reliably and reduces the stress of cold starts. That’s why the grid heater is there.

Term

glow plugs

"because you have glow plugs. If you have a 25 or 26 Ram, you also have glow plugs."

Glow plugs are electrically heated elements used to warm a diesel engine’s combustion chambers for easier starting, especially in cold weather. They help ignite the fuel more reliably until the engine reaches operating temperature.

Concept

50 state compliant

"after we had launched the Monster Ram Gen 2, which is the 50 state compliant monster that you're referring to."

“50 state compliant” means the modification or emissions-related product is legal to use across all U.S. states under emissions regulations. For diesel performance parts, this usually implies the system is designed to meet federal and state requirements.

Term

engine ate the bolt

"I want to get one of your Monster Rams because it removes, it replaces the grid heater and my engine ate the bolt and blah, blah, blah."

This phrase means a bolt or part broke off and got into the engine. When that happens, it can cause serious damage very quickly.

Company

Protect Diesel

"So I called this guy Brad and he owns Protect Diesel in Kamloops, Canada. I said, how common is this?"

Protect Diesel is a shop that works on diesel trucks. The host is citing them to show the problem is happening in the real world, not just online.

Term

EGT

"response, to remove airflow restrictions, slow down your turbo shaft speed, EGT, like all the [2204.5s] things that the benefits that it has performance wise, the side, the big side bonus is that"

EGT means how hot the exhaust gases get. If EGT is too high for too long, it can cause damage, so lowering it is usually a good thing.

Term

heat cycles

"And when over many, many heat cycles with cold, hot, cold, hot, cold, hot, [2242.6s] cold, and with a 30 Hertz vibration at idle, which is a pretty, you know, you know what a"

Heat cycles are when the engine repeatedly heats up and cools down. That expansion and contraction can loosen parts and make failures more likely.

Concept

cold starts

"...for those people who still need cold start capabilities, we include now up to four heating elements..."

A cold start is when you try to start the car in freezing weather. Diesels can be harder to start then, so heaters warm the air to make ignition easier.

Part

dual heat capable Monster Ram

"...we now offer the dual heat capable monster ram. So you can thread two of the 750 watt coil heaters..."

“Dual heat capable” means the intake can use two heaters instead of one. That gives the engine more help starting when it’s very cold.

Term

3000 total watts

"...we have an inline billet heating device with two more. So you can have 3000 total watts of, of heating for your extreme cold starts."

“3000 total watts” refers to the combined electrical heating output available from multiple heating elements in the intake system. The speaker frames this as support for “extreme cold starts,” where more heat can improve ignition reliability. It’s essentially a capacity claim: more wattage equals more heat energy delivered to the intake air.

Concept

preventative maintenance

"Well, I think a lot of the, a lot of the topic requests or conversations I have are focused around preventative maintenance. And I also talk with engine builders and know what an engine costs."

Preventative maintenance means taking care of the vehicle before something breaks. Instead of waiting for a failure, you do the right service and fixes early to avoid big repair bills later.

Term

differential covers

"when I saw that the same thing goes for like the differential covers and the engine oil pans and just all those could be entire podcasts by themselves..."

A differential cover is the protective housing over the gears that help the wheels turn. Better covers can help prevent leaks and damage, which matters for long-term reliability.

Term

engine oil pans

"...the differential covers and the engine oil pans and just all those could be entire podcasts by themselves..."

The oil pan holds the engine oil. If it leaks or gets damaged, the engine can lose lubrication, so it’s a key part for reliability.

Concept

F1 racing

"I think where Gale comes from with his endurance racing history is more akin to like F1 racing and trying to shave off a hundredth of a second. And that and to shave off a hundredth of a second requires absolute precision engineering and maybe a ton of money to do that."

Formula 1 (F1) is known for extreme precision engineering and small performance gains that can decide races. The speaker compares diesel performance engineering to that level of precision—where tiny improvements and tight tolerances matter.

Concept

turbocharge

"...he was the Volvo hired Gale Banks in the 70s to turbocharge their first what would become their first turbo sedan."

Turbocharging uses exhaust energy to spin a turbine that forces more air into the engine. That allows more fuel to be burned efficiently, increasing power—while also requiring careful engineering to manage heat and stress for long-term reliability.

Concept

OE level engineering

"And so he's been doing OE level. And even before that, you know, with with marine applications or whatnot, but he's he he taught at General Motors."

“OE level engineering” means designing aftermarket solutions to match original equipment standards for fit, durability, and performance consistency. In this discussion, it’s presented as the key difference between hype-driven upgrades and systems built for long service life.

Company

General Motors

"...but he's he he taught at General Motors. He's like there. So he's got a very long history of OE level engineering."

General Motors (GM) is a major automaker with large-scale powertrain engineering resources. The speaker mentions Banks teaching at GM to reinforce that his background is rooted in mainstream OEM engineering practices.

Term

emissions

"And I think in the future... It’s the only way to pass emissions. And once this administration is gone... the engines are going to get bigger. It's the only way to produce less emissions and still make the power you got you have to go bigger."

Emissions are the dirty stuff an engine puts into the air. Laws limit it, so truck makers have to redesign or tune the engine to meet the rules.

Term

engine dyno room

"...I can stop by the engine dyno room and check it out I can jump on the phone and talk with a shop somewhere..."

An “engine dyno room” is where engines are tested on a dynamometer, which measures output like horsepower and torque under controlled conditions. Dyno testing is crucial for validating tuning changes, diagnosing issues, and comparing results across different configurations.

Part

supercharger

"There's a freaking Whipple three liter supercharger on the track is amazing in it. And it's ungodly loud."

A supercharger is a device that forces more air into the engine. More air usually means more power.
