Not A Typo: Quad Turbo. LS. V12.

Quad Turbo LS V12

In our short time here at MC&T, we’ve seen some pretty wild engines. There’s the Hellephant crate engine. There’s the naturally aspirated LS V12 from Australia. There’s this 1,500 hp twin-turbo monster from Nelson Racing Engines. There’s even an LS-based V16 engine that we are absolutely in love with. Then there’s this. A quad turbo LS V12 engine from Australian engine management systems developer Haltech. The results are depicted in the video below. Needless to say, it’s worth your short attention span. If you want to fast forward through the details, the noise starts at around the 6:40 mark.

You may have caught that Haltech is actually utilizing the LSV12 engine mentioned before, albeit with a quartet of turbochargers. Like a Bugatti Veyron. Or a a Chiron, if you prefer. Total displacement of this boost buckled beast is 9.7 liters.

Before Haltech fitted the LS V12 with four Garrett GT3582R turbochargers, the naturally breathing engine was producing just over 700 horsepower. Haltech claims the Garrett turbos are perfect for the project because they are a “sweet spot of compressor efficiency for this particular model.” Each turbo also handles three cylinders, or just 2.5L of engine displacement, which makes their compact packaging no issue at all when it comes to force-feeding extra air into the combustion chambers. Keeping things from blowing up are four Turbosmart Gen-V CompGate 40mm waste gates, one for each turbo. Haltech says that gate pressure is just 7 psi, for now. Two Gen-V Race Port 50mm Blow Off Valves are also mounted to the inlets of the intercooler.

There’s plenty more that went into the quad turbo LS V12 build, but the brain that’s making it all work in harmony is Haltech’s Nexus R5 ECU. The control module is so powerful, it can control most vehicle functions, and the company has gone on to brand it as a “Vehicle Control Unit,” or VCU for short. Built in features include dual wideband controllers, wireless communications, and data logging capabilities.

Haltech hasn’t yet fitted this monster quad turbo LS V12 engine to the dynamometer just yet, so we’re hoping to report back with final output number soon. Until then, let your imagination run wild as to what build you’d liked to strap this monster into.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.
