Gale Banks breaks down the math behind GM’s new 8.3L Duramax V8 (L6P “Mongoose”), evaluating its 555 HP rating, CGI block, flat torque curve, and how a Derringer tuner on an L5P beats it today.

Discover the dirty secret hidden in factory Duramax oil pans: an elevated drain plug that traps nearly a half-quart of contaminated sludge every oil change, and how the Banks CoolRunner pan cures it with complete drainage, FlowThru cooling fins, and +2 quarts capacity.

Banks introduces the world’s only true 5-inch DPF-back Monster Exhaust for 2024–2026 Duramax 6.6L trucks, using a patented Exhaust Pressure Module to cut backpressure without triggering check engine lights or melting trailers.

The Banks R866SC V8 6.6L Supercharged Diesel is an engineering powerhouse delivering 600-650 horsepower. Featuring a 3.8L Whipple supercharger and custom FEAD, this complete package is built for extreme performance.

Banks Derringer High Output tuner does more than just add power to your 2024–2026 Duramax 6.6L. Level 2 is specifically calibrated for improving fuel economyby adding more boost and optimizing fuel injection. And, Level 2 delivers an impressive 60 hp and 90 lb-ft to the wheels. For even more power, bump up to Levels 3-6 for power increases up to 86 hp and 178 […]

On all 6.7L Cummins, the factory grid-heater bolt is a known risk: if it breaks loose and reaches cylinder #6, engines are replaced—not repaired—an outcome costing north of $30,000. If you do nothing: the stock grid-heater bolt stays in the system—every start is a roll of the dice, and other replacements “fixes” still choke air flow. […]

Hector’s 2015 RAM 3500 threw an intake-heater code, then his remote start system stopped working. He pulled his intake plate after reading about the killer grid heater bolt. To his horror and delight, he saw “the nut had broken off and was just sitting there” — one drive from disaster. Rather than install another factory heater plate, […]

Your 6.7L’s stock intake elbow kills airflow with its sharp bend and restrictive air path. That added restriction makes the turbo work harder and dulls response. A Banks Monster-Ram intake elbow takes a different route—literally. We rerouted the #1 fuel line and replaced the restrictive grid heater which allowed us to open the air path and remove […]

RAM 6.7L engines can suffer catastrophic damage as a result of a bolt inside the factory grid heater, which melts and drops into the intake manifold. In this 8-minute close-up, you’ll see exactly what fails, where to look on your truck, and the upgrade that removes the weak link. If you own a 6.7L, this […]

Banks Power by the Numbers breaks down the real data behind a record-setting 2025—from millions of video views to testing fuel burned and parts shipped worldwide.

A Canadian diesel mechanic visits Banks Power and gets a firsthand lesson from Gale Banks on air density, cold starts, and real engineering behind reliable diesel performance.

“This video is a huge full-circle moment for me,” says an emotional Dave Bell, owner of Dave’s Auto Center in Centerville, Utah and the star of the wildly popular YouTube channel of the same name. “I’ve looked up to Gale Banks since I was 15 years old,” Bell continues. “His engineering and genius has paved the […]
