The April 2008 Motor Trend tested a 2008 Charger R/T with the Road and Track Performance Package. It did a 5.5 sec. 0-60 mph run. The R/T Challenger should do a little bit better if the hp of the 5.7 is increased from 330 to 350-380 hp.
Well the Charger R/T depending on which package you got whether it is the standard R/T (produces about 340 hp) or Road and Track Performance Package R/T and Daytona R/T (350 hp) with the same amount of tq at 390 ft-lbs. The Ram's increase was from 345hp & 375ft-lbs to 380hp & 404ft-lbs. At this point we really don't know for sure what it will produce precisely but estimate around 375-385hp & at least 404ft-lbs of tq. The problem is that the numbers are far too inconsistent to say for sure what the acceleration time is on the 5.7L that it is hard to say on top of the fact that we don't know how much hp & ft-lbs of tq it will produce.
