how much horsepower is a dodge hellcat
âAutoTechnicianâ took the details of the Challenger Hellcat and added the 392âs published power and top speed (475 hp, 182 mph top speed) to chart the Hellcatâs top end. The chart, for illustration only, is at right; it shows 198 mph at 600 horsepower, and 214 mph at 700 horsepower. He assumed a 5,800 rpm redline, based on Dodgeâs photo of the SRTâs gauges; however, Hellcat makes peak power at 6,000, so the redline is probably a bit higher.
