Gale Banks Engineering MegaMax Blown 7.0L LML Duramax engine being built in Azusa, California. See the full build-up in the January 2012 issue of Diesel Power.

Deep within the prototype and engineering building on the Banks Azusa, California, compound—there’s a new supercharged diesel being built. Behold, this 7.0L (427ci) Duramax features a 2011 LML engine block (the strongest DMAX block ever built), a billet-steel stroker crank, H-beam connecting rods, and forged-aluminum Mahle pistons. Rounding out the long block are a set of production-LML-based-cylinder heads (that have been CNC-ported) and a pair of belt-driven CP3 injection pumps.



But the biggest news about this four-digit-power-producing engine is what you won’t find on it—there's not going to be a single turbocharger. Instead, it’ll feature a 4.0L Lysholm-style supercharger and a multi-port nitrous system controlled by Banks own hardware to supply the airpower.

This MegaMax engine is destined to speed the Banks dragster down the quarter-mile in 2012, and when it does, you’ll be able to hear its zoomie headers from a mile a way. Cause without any turbos to restrict the exhaust flow, this supercharged Duramax will be the loudest common-rail GM diesel you’ve ever heard! We can’t wait to see it run.

Want to know more? Check out our full-coverage of the engine build-up in our January 2012 issue, which goes on sale December 6, 2011.

The 7.0L engine is being built with the strongest Duramax parts on the planet. H-beam connecting rods, forged Mahle pistons, and a billet-steel, internally balanced stroker crank are all being fit into a brand-new LML engine block.
The 7.0L supercharged Duramax is mocked-up in the engine compartment of the Banks Sidewinder Dragster. Note the trick dual belt-drive CP3 pumps.
