INTAKE MANIFOLD AND TUNING ARE THE 2 KEY DIFFERENCES IN RAM AND DURANGO...And no Ram intake wont fit!

STEVE

However....the 6.1 intake will.:thumbsup::thumbsup::thumbsup:

How does the 6.1 intake affect the TQ curve. One would think that if it only had a positive influence they would have used it.

It pulls harder on top end...and reason they dont use it on 5.7 is because of this i imagine.They who have swapped 'em claim 10-12 HP gain with stock throttle body and more (up to 10 more)with larger TB that can be fitted with the 6.1's intake. Although I have been unable to find any comparing dyno #'s. Plus its a WAY KOOLER LOOKING INTAKE THAN OUR PLASTIC JUNK ONE.

^^^but also the 6.1 intake is more likely to get heat soaked being aluminum.
Regardless, the intake of choice would be the 6.4L one with its dual stage runners which give you the low end tq and top end pull.

Although it won't fit the 5.7..:-?:-?. My son drives a Nasty 6.1 SRT Magnum and has never had heat soak problem. Unlike our 03' Cobra which definitely does get heat soaked since its Blown. I doubt a normally aspirated 6.1 would Ever experience heat soak loss.
