Gear ratio
If there is one place I may toy around on mine it's the gearing. I'm assuming it will have 3:06 or so based on Viper and Charger configurations. If a a 6speed, some much steeper gears can be had and still be highway friendly. I'm thinking 3:73 on the low side and 4:10's possibly. Be interesting to see what limited slip unit they use as well?? |
RE: Gear ratio
To get the same final drive ratio the A580 transmission has with in the SRT-8 cars. They could easily use a 4.10 rear-axle with the top .5 overdrive that the T-56 Tremec has and still be ahead.

RE: Gear ratio
Lets hope that the rear end ratio option will be available. I'd like a 410 or 411 please.

RE: Gear ratio
Agreed. It is interesting that the Shelby GT 500, w/ 6 speed is a 3:31 final ratio. I suspect the main culprit is EPA. Can't meet the mileage and emissions output limitations turing the gears we're thinking...just a guess.

RE: Gear ratio
Do you think that is why the factory usually doesn't have the rear end ratio as an opton anymore is because of the EPA? To get the millage. You'd think that the factory would have the one gear as standard for all the cars and then have an optional gear or 2 for people who wanted it. You can still order the gearing in trucks. Probably for different pulling/hauling situations.

RE: Gear ratio
I've wondered about that one quite a bit. Probably the EPA won't let them have a lower-speed axle due to the increased fuel consumption. I wish we could get rid of the EPA. They have screwed cars up.

RE: Gear ratio
While I would like a higher rear end ratio....I would really like to see a 6th gear that will put the rpm's at around 2K for highway cruising. Not only for gas consumption (what a laught)
but to minimize wear on the engine. I plan to keep it a long time.....maybe pass it on to the kids. Jeremiah 29:11 |
RE: Gear ratio
The 6spd gearing even w/ 4:10 should place your Chally at comfortable cruising speeds...especially for a HEMI to withstand;) |
RE: Gear ratio
If I can get 2K RPM at highway cruising speeds then 4:10 gear ratio has my vote.
What is real cool are some of the cars do not need shifting into 2nd gear until 60-70 MPH. Mostly because they have a lot of torque and the gear ratio is not too high. As a result, they beat other cars at the start and win because there a fewer gear changes since they win in 2nd gear. |
