I was just curious as to why the 5.7 hemi in the ram is rated at 390hp, and the Challenger is rated at 375? Are there some mechanical differences in the two engines, or does Dodge like to underate the 5.7 in the Challenger to show more of a power gap between the 5.7 and 6.4.
It's because they have a oil pressure controlled intake. why you wouldn't put it on the premier sports car is beyond me.

(1) the intake on the Ram is the same active intake on the 392 Challenger
(2) Dodge would rather close the gap in the performance numbers of their TRUCK to compete more with the Silverado and F150 than their cars (Camaro vs Mustang).
Not trying to kid myself, but the R/T has to be under rated. The performance of the R/T tells me it has more than 375 hp. Maybe not much more, but more.
When someone asks me how much hp my R/T has, I don't exaggerate, I tell them 375....but deep down I know it's more.
Hasn't anyone dyno'ed a 5.7 at the crank to discover the truth?

I agree...my suspicion is that the difference in numbers came purely out of marketing politics that decided the Challenger RT could not be "390" while the (then current) SRT8 was just sitting a step above 400.
Was there ever a Hemi Ram SRT8? What was that rated?
It's not that I really needed 370 hp...but having 150+ hp riding shotgun at a moment's bidding w/o a 6000 rpm moonshot is what makes me feel like I'm in the right car for me. The roar of a v8 seals the deal!
The Google keyword is "ethanol-free gas". The truth is coming to light. Check out http://pure-gas.org/

Never was an SRT8 Ram but there was an SRT10 Ram (2004-2006). They made it in a std cab with 6sp manual and quad cab with auto.....had the 8.3L Viper motors rated at 505 HP....I owned a 2006 std cab...badazz truck..
Chrysler has a reputation for under-rating HP...when you do the math (RWHP, ET vs weight, etc) on the 6.1 engines they better match an engine putting out cloeser to 450hp than 425hp.......similiar to this the 6.4 is probably putting out closer to 500 than 470...

Those SRT10 Dodge trucks (I refuse to call them "Rams") are beautiful, especially the regular cab ones.
