Incorrect statement since the tranny and drive shaft are not the same from
the 5.9 to the 4.7 model. The lost for a 4.7 five speed is around 11.54
percent and the auto version is only 19.2 percent drive lost. My truck will
be dynode by JBA for the before and after installation of the prototype
headers.
I had to laugh when I seen Kenne Bell Dyno specs and seen others that
already had there 4.7 done on a Dynojet machine. Big differences!

A stock Dakota R/T will put right around 190 HP to the ground, depending on
if it is a RC or a CC (more distance in a CC for the HP to travel down the
driveshaft)
based on the few dyno sheets I have seen, and shows that have dynoed stock
R/Ts.That means that if you take the stock manufacturer's rating of 250HP,
that you are looking at about a 26% loss of HP in the tranny, driveline,
and associated friction.
If you apply that same percentage to this SC 4.7 (yes it is) then you get a
flywheel SAE Net HP rating of about 346 HP. That figure is right on the
money as far as most claims of increases of 50% or more. But the thing is,
after the SC, just how much more can you do ? After that, all mods will
only realize incremental increases in HP at best.
Not trying to discount the KB, hell, I wish I could afford one on an R/T,
or any vehicle for that matter, and yes, next to the R/T I used to have,
this truck should eat it's lunch, but it's just food for thought.
