I have heard this and it still does'nt change the fact that the 5.7 HEMI is putting down numbers that have it at 390-400 hp at the crank. So I would think that the intake on the Ram is putting it at more than 400 HP. Anyone want to put their Ram on a dyno. Not saying that the Ram's 5.7 is not putting more hp down than the sedan 5.7. Just saying that the R/T 5.7 is putting out around 400 hp. The 1/4 mile times some good drivers are running show this to be the fact. And base line dyno runs show this to be true. I can't blame Dodge for under rating the 5.7 because some folks would look at only the hp #s and forget that the SRT-8 package is more than an engine. Brembos, lighter and wider wheels, better handling suspension and optioned to the teeth. Lets see what the 6.4 does to shed light on the 5.7 in 2011 hp rateings.
