SUPERCHARGER, it will improve your mpg's too.
And a less restrictive exhaust and air intake will also improve it.

 

Well that's a bit extreme...

 

Ya wana get thrown back into your seat? Then this x 100.
RIPP makes one with truely impressive gains...we're talkin SRT8 type gains.

Everything else pales in comparison and will not net huge results...but they will get you some results.


The rear end gearing is pretty tall as well, what?...3.09s.... So its not gonna geat real quick, real easy or real cheap.

One thing you can do on your own that may improve the acceleration "feel" is to learn to shift it manually.

Good luck.

 

That can be easily fixed with an inTune DCX tuner. The Durango is designed for less spirited driving than is a sports sedan, the former has a "gentle" throttle for the soccer moms etc. The inTune will fix the lagging throttle, change upshift points for more lively driving around town, etc. No intake, exhaust, etc will do as much for the $$$ spent. Get one.

I believe one member put in a different torque converter, if you search you'll find it.

 

I believe the 2013 R/T has a 3.45 final drive. I pulled the info from this Car and Driver site (You can select the model):
http://buyersguide.caranddriver.com/...o/specs/353193

I just checked the build sheet for my 2013 Crew with the 5.7L and it has the 3.45 rear axle ratio.

 

I just got this today, and drove it an hour after it arrived, WOW was it simple Mod, and really gets to the brain of this setup.
Absolutely setup stock for a Soccer mom grocery shopping, not the Bonfire scene in Breaking Bad with Walt and Walt Jr's Hemis.
It's seems like a restriction has been lifted, and it feels and drives like a V8 muscle car should.

Diablo DCX and Edge racing 3200 stall torque converter. Thats all you need unless youre trying to impress the internet. The Superchargers are making good power but give them 10k miles and lets see how durable its been to forcebly add 50% more power rather than extract the power thats available. Also those are using a centrifugal blower aka no high power unless really revving it out.

 

That would be me. Still best bang for the buck yet (aside from the '14 srt-8 interior swap.)
