Hemi Dyno Test
Straight from Chrysler Corporation! We'd love to publicly thank the person who sent this, but must keep his name confidential...not that we know his real name! Note the maximum horsepower on this dyno run - 433.5 hp (that's 463 corrected horsepower!), 405 lb-ft of torque at 6,000 rpm. Max torque was a whopping 472 lb-ft at 4,000 rpm with 336lbs of load (also max load; corrected). So when did it reach 425 horsepower, its rated level? If you use the corrected figures, it had passed 425 horses at 5,200 rpm!
It should be noted that this is not necessarily a test from a production engine. Our source wrote: "the dyno tests were conducted in cells 12 and 13 of Building 135 in the old Highland Park complex." The test sheets were found nearby, apparently discarded.
