Video: Behold Nelson Racing Engines’ 1600HP 572ci Twin Turbo Hemi

Oh. My. Gosh. Here’s possibly the sickest Gen II Hemi (426) we’ve ever seen. Let’s just take into account who Nelson Racing Engines is first. NRE is owned and operated by genius fabricator and engine master Tom Nelson, who has not only earned his stripes building insane horsepower-spitting engines for all makes and brands, but has taken a particular shine to boosting the living daylights out of said engines. So much so, that one of NRE’s specialties is their Mirror Image Turbo kits, offering dual turbos mounted in direct and identical opposition from one side to another. It’s enough to make your OCD side leap for joy.

But back to the topic at hand: NRE started with an aluminum Gen II Hemi block and punched and stroked their way to a whopping 572 cubic inches before installing NRE’s own billet throttle body and snout (which incorporates dual blow off valves) attached to one of Nelson’s own fabricated intake manifolds (with internalized linkage) plumbed with 16 fuel injectors, injectors that are fed by parallel Aeromotive fuel regulators, a Billet Specialties front drive system, stainless forward-facing turbo headers, a Ron Davis intercooler, and features a distributorless ignition system.

So what does this all add up to? Try a fully streetable 1,600 peak horsepower at 6,100rpm. With 14 lbs. of boost, the big elephant is twisting out over 1,260 ft. lbs. of torque at 3,400rpm. But hey, not all of us need all 1,600 ponies, so what if we drop the boost in half? Easy. The NRE Hemi snarls out a “mellow” 850 horsepower for some “country cruising,” as Tom says in the video below.
