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.
