The guy in our club who got the new 09 SRT 6 speed with 3.91 drove to Virgina beach soon after buying it . And said he averaged 20 to 21 mpg on the road. In my mind that isn't bad . But he did admit the mpg dropped when pedal to the metal . I get a average 20 to 21 with my 6 speed R/T with normal to lead foot driving . And best of 26.78 cruising around 60 on rural roads . And 24.5 doing 80 + on intersate. Can't wait to see that big Hemi run at the track.

The window sticker on my R/T say's 3.92 also. Steve the guy with new SRT said 3.91 . I've seen it both way's in advertising . I don't understand that . Can there be two different ratio's . I don't think so good anymore. Too many birthday's. And in the 09 brochure I have they say 3.91 for the track pack for the R/T. What is the story on this. Can someone review how the ratio is figured. How many teeth on the ring gear to pinion. Or what. And did the 08 SRT come with pos or didn't with the automatic. And only the 09 SRT with 6 speed does get the pos .

Yeah I got my info off the sticker also. Says 3:92. The old 8 3/4 rear end had 3:91. Thats whats under my 70. But someone might have more info on this, either way thats a stout gear.
