Hennessey Performance has just unveiled the incredibly powerful 2019 Dodge Challenger SRT Hellcat Redeye HPE1000 upgrade.
When Dodge introduced us to the Demon’s replacement, the 2019 Challenger SRT Hellcat Redeye, it seemed almost like a step backward. Sure, it still had the Demon’s 2.7-L supercharger, and the same torque reserve system, transmission brake, and after-run supercharger chiller, but the 6.2-L HEMI V8 no longer demanded the very finest of racing fuel to produce 840 hp. Instead, the engine had been detuned to produce 797 hp and 707 lb-ft of torque.
Leave it to Hennessey to ensure that no giant engine will ever be detuned on their watch. The same 6.2-L HEMI V8 that powers the Redeye has been given the Hennessey treatment to now produce over 1,000 hp thanks to their HPE1000 upgrade.
Getting to 1,000 horses wasn’t too much of a jaunt for Hennessey. First, the old 2.7-L supercharger is tossed for a larger 4.5-L model. Next, Hennessey’s speed engineers provided a new supercharger pulley, throttle body, stainless steel long tube headers, high-flow catalytic converters, a high-flow supercharger bypass valve, upgraded high-flow fuel injectors, a boost-a-pump upgrade, HPE calibration upgrade, and a new high-flow air induction system.
Once everything is said and done, the Redeye now produces 1,035 hp and 948 lb-ft torque at the crank. At the rear wheels, the Redeye puts out 880 hp and 806 lb-ft, which represents a loss of only 15%. That’s actually quite good by Hennessey standards.
And of course, it wouldn’t be Hennessey without a bunch of new badges, a new serialized plaque, new floor mats, and a one-year or 12,000-mile warranty.
Price is $34,950 for the upgrade on top of the price of the Redeye, which is $71,045. We haven’t been provided performance specs from Hennessey to know if that $106,000 price tag is worth it, but with 1,035 horses at your beck and call, it seems like a justified waste of money.
