Heart-Stopping Power: Gale Banks' 1200-HP Tri_Charged Duramax

When it comes to motorheads, the hunger for power seems near universal. According to Wikipedia, hot rodding was birthed in Southern California in the late 1930s. People raced modified cars on dry lake beds northeast of L.A. with rules established by organizations like the Southern California Timing Association (SCTA). Unofficial street racing took place anywhere where you had more than a handful of teens and a stretch of straight, flat road.  

Most of these teens grew up and moved on, pursuing careers, supporting families. Then there were the others for whom the experience of speed and power ignited a passion that became the fuel that powered their careers. One of these  boys with an aptitude for mechanics was Gale Banks, now president of Gale Banks Engineering. Three parts engineer, one part "mad scientist", Banks has spent a half century tinkering with technology, keenly focused on improving the internal combustion engine. His special interest has been diesel engines.

To give you an idea of just how far Gale Banks is willing to go to extend the capabilities of diesel engines, Greg Acosta wrote this story for EngineLabs.com: More Power With Less Boost: Banks 1,200-HP Tri-Charged Duramax.

One of the things that makes this article so significant is that the author is not only writing about a briilliant engine builder at the height of his powers, we're encountering the rare transparency of a man who is sharing everything openly. Banks has been part of a world where secrets are the norm. Competition means finding an edge, not sharing your edge. 

The Duramax engine Banks has been incrementally improving is suitably named "Mad Max". It's something he's been focused on and fine tuning for two-and-a-half years. In this article we don't just read details about the power this setup can achieve. In addition, Banks provides a breakdown of what all the readouts mean, and what the dyno data really means. As Acosta puts it, "In a world where data is hoarded and protected like the gold in Fort Knox, Banks is freely sharing not only his findings, but explaining the findings as well."

For Banks, one of the key metrics is Manifold Air Density (MAD). Since it's a Duramax he's been playing with, could this acronym be the secret to why he calls this engine a Mad Max?

Acosta writes, Using his preferred metric of Manifold Air Density, Banks breaks down the amount of air he needs to reach his 1,200-horsepower goal, and how, exactly, it will be measured on the dyno. “Manifold Air Density is the best indication of the engine’s power potential. You can forget about boost pressure, because it’s part of the MAD calculation. Manifold Air Density is the bottom line,” says Banks.

The engine was originally built for a Monster Truck. If you'veever wondered what those monsters had under the hood, this story will peak your interest on that level, too. The photos draw you in, but the details are what make this a valuable article to be bookmarked by any serious gearhead seeking to learn how to make dyno adjustments for maximum diesel power.

The New GM 2.8-liter 4-Cylinder Diesel Engine Is at the Heart of This Mad Max ISV

Tell me this doesn't look like something out of Mad Max. (GM Defense)

Sometimes art inspires life. That was my first thought when I saw this October story in Car and Driver about GM's new Infantry Squad Vehicle (ISV), which looks like it would have been right at home in the storied Mad Max series. (How fun it must have been for the folks who were assigned to create all these bizarre rat rod-like contraptions for that post-apocalypse thrill-ride.)

Three companies had been given a million dollars each to develop a light-weight off-road troop carrier. Every aspect of the design had functionality as its criteria. It had to be light enough for easy dispatch from a C-130 or C-17 transport plane, as well as for sling lift by UH-60 Black Hawk helicopter. The nine-seat ISV also had to be strong, durable, and off-road nimble. GM Defense got the assignment.

In developing the concept, GM Defense began with a Chevy Colorado ZRT as a foundation. From there it gets exciting as they clamped a new GM 2.8 liter, 4-cylinder diesel power plant in place under the hood. Ezra Dyer reminds readers that the specs are classified, but experienced journalists have no problem sharing their hunches as regards the possibilities. Dyer knows well the Colorado this machine is based on.

Dyer also shares a little GM history as well, noting that the automaker "started building trucks for the military in 1914, sending 90 percent of its trucks to the front in World War I. More recently, in the the 1980s, they built more than 70,000 lightly militarized Blazers and Silverados: the Commercial Utility Cargo Vehicle (CUCV). Plenty of those are now in private hands, their naturally aspirated 6.2-liter diesels still grumbling away. So the ISV continues a long tradition of modifying GM trucks for military duty."

The contract GM Defense signed was worth $214 million for 649 vehicles. Ultimately the army is looking to acquire 2700 of these light-weight beasts. The occasion for this article in October was that the company had just deliver the first of the lot. To get the full story, plus some cool video showing off what the ISV can do, follow the link below. Looks fun.
