WEAK R/T PERFORMANCE CURE ???
 

After owning my 2009 R/T for two weeks, it amazes me that this car is not faster. The culprit has got to be the 3.08 rear end gearing.

Has anyone looked into changing the rear end ? In order to wake up this car, I would swap the rear end and get the 3.92 gears of the 6 speed model.

Anybody try this yet???

Wait til after 1000 miles. Should wake up some as some have said perhaps the computer is holding back some hp for break in.

Let everything seat as the car needs time to "break in" before judging what you have.....you may be surprised......then if not.......get the check book out....

I hope you don't drive on the freeway much. As a 3.92 gear with a auto trans will be turning some high rmp's at freeway speeds.

there has been reports of the rt doing 5.3 0-60 with a non broken in engine so imagine when broken in. Make sure you drive aggresively so the computer picks that up.

It is the gearing!

My 67 charger had the granny 2.94 gears.

I changed it to the 3.55 and it did wake it up.

I would not go that high yet. Try the 3.55's first is my recommendation.

too bad getting gears cost 6k right now....[:@]

RE: WEAK R/T PERFORMANCE CURE ???
 

mine seems a bit sluggish too, but I've heard it will wake up after the break in.
I'm only at 200miles now.
BTW........how many miles are we supposed to take it easy with this car before we open it up?
I haven't gotten that far in the manual yet......8)

dealer says 300
manual says 500

(srt)

Mine was what I thought was very week until about 600 miles and it keeps getting better. I'm at 1200 now since I got the car the first week of July and it's a beast.

RE: WEAK R/T PERFORMANCE CURE ???
 

500 miles is what the owners manual states. Some WOT throttle allowed but limited.

ANDRE... RUBBERBNDMAN... and MOPAR2YA all say DRIVE IT LIKE YOU STOLE IT... right out of the box. Hasn"t hurt the SRT"s the slightest little bit from anything I have heard. [sm=gears.gif]
Dealers and manufacturers have a warranty to worry about so definately want to have you play nice.

I've broke loose at 200-miles. And she was a beast. At 300-miles we've shot the 1st Zoomers video seen on YouTube. And at 500-we've done some burn-outs and installed the Zoomers X-pipe. She sounds like a 70's muscle car now. I think Andre and the fellas are right, drive-it like you stole-it; it's a Hemi by the way. [8D]

My Challenger is about to hit 600-miles tomorrow. Maybe a trip to Nevada is in order to break her in further. [sm=gears.gif]

I've got 3.92 gears on my Ram... and can cruise at 80mph's under 2300RPM's... So im not sure where your getting that from... My truck is much better on gas on the highway... I bet I could put it in cruise control at 90mph and still be under 3,000rpm's...
Hey kevin I've got your 3.92 auto gears... for about 3k... Make a deal?

RE: WEAK R/T PERFORMANCE CURE ???
 

hmmmm very tempting offer.... let me get the car first haha,
