The Hammer was dyno-tested while heat-soaked, so these results could theoretically go up if Hand had iced down the blower and let it sit. But he wanted real world results. His technique is to start with a cold car, bring up the engine coolant temp to 180 degrees and then make the pull. All told, the Hammer pounded out 579 rwhp and 572 lb-ft of torque using SAE correction. In Standard correction factor mode, those numbers jump to 600 rwhp with the Sansone mods and 508 rwhp in stock Roush trim.
