How does that compare to the Helliphant? I see a comment about "If exceeding 900RWHP", but I thought the Helliphant was rated at 1kHP? Then again, I don't know how much is lost between the torque converter, and the rear wheels.
The Hellephant is a totally differant animal.It's a 426 that uses a complete custom machined aluminium block by TEI and is under rated at 1,000 hp,the majority of Hellephants are dynoing over 1100 at the crank.The 6.2 Demon is roughly 376 cubes,so it's a full 50 cubic inches smaller,and uses a factory cast iron BGE block. GM has countered the Hellephant with it's old school carburated 1,000hp 632,that is alot easier to buy,so hopefully Stellentis see's fit to release another run of the Hellephants
Based on what we're seeing from the
Demonology dyno and quarter-mile drag tests, the Hellephant crate engine is closer in output to the 1,200hp mark, a number we're sure will thrill Mopar enthusiasts and not so much the Chevy and Ford guys. We can thank Mopar Performance for some trick design work on the all-aluminum crate Hemi, but some of the credit also goes to a company called
Tool Engineering International (TEI)—a company we haven't mentioned before. The engine block for the Hellcat and Hellcat Redeye crate engines is a cast-iron production piece, but the 426ci Hellephant shares its TEI-sourced aluminum block with the new limited-edition 2021 Drag Pak Challenger we told you about
here.
GM's 1,000 hp 632 isn't production limited like the Hellephant,and is readily available,so hopefully Stellentis gets off their asses and builds more Hellephants to counter GM's 1.000 hp offering.
Unlike some of its other high-performance crate engine offerings, GM isn't placing a cap on ZZ632 production, and, in even better news for speed freaks, the engines will be kept in stock rather than being built to order. We don't have pricing yet for this monster of an engine, but we suspect it will land somewhere north of
the approximately $16,300 that is being charged for the ZZ572.
