GM 8.3L Duramax Diesel: Gale Banks Does the Math
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.
First diesel to finish Baja 1000
Baja 1000 Dodge Cummins drove to Ensenada, Mexico, and ran the full Baja 1000, stopping to pull a competitor out of a mud bed then finished a very close third and drove home after beating most of the gasoline entries, this is the first diesel to finish the Baja 1000.
The Kroeker-Banks 2003 Dodge 2500 turbocharged 5.9L Cummins diesel, racing in the Stock Full Class at the 2004 Baja 1000, became the first diesel-powered vehicle to finish the grueling race. Outfitted with a Banks Big Hoss® Bundle, Kent Kroeker not only raced his truck, he was able drive his truck to the event from San Diego, carried more than 400 pounds of equipment in the bed, and drove back home after the race from the bottom of Baja. In the truck’s first Baja 1000, the KORE truck finished third in its class and got and incredible 12.5 mpg.

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 […]
