The 4.56 in the 2005 is looking sweet

[earl lee]

will those be in the standard cab or the crew?

 

[Hemi57]

is the difference in 4.10 and 4.56 much at all?

Yes. Both.

Definitely on my 'To Do' list. I'm waiting for Unitrax to piece out a kit for our trucks.

From a thread I started a while back:

Thank you for your continued interest into UNITRAX. I have finished my
research on how to perform the ratio change in the 04 SRT truck.
However, I am waiting for Dana Corporation to call me back on the
availability of the ring and pinion set. I will email you as soon as I
hear from the product manager.

Thank you,

Called these guys today to get an update. He told me Dana would be shipping the gears by mid-September. Then Unitrax will make up a complete kit and figure out a price for it.

Guess I'll call back in a month or so!

9seconds contacted them initially, then I called them about a month ago. Which means it's just about time to ring their phone and bug them again! I may call next week and see what's up.

Land Speed Record?

Now that DC is going with the 4.56 gears I wonder if the 2005 trucks could still do the speed record that the 2004's have set?
Or did they feel all along that this truck needed the 4.56's, and just used the 4.10's just to get that title.

RPM on the 2004 was just under 5000 rpm @ 154.5. RPM on 2005 will be 550 rpm higher where the Viper engine makes just a few more horsepower. I'd say it will do it, no problem. Maybe slightly faster.

I have read posts about some guys running 5:13 gears, since top speed is not an issue (no place around here to go that fast for that long), will the 5:13 gears add that much more in real street performance?

gears?

I have installed 5.13s,I like the response,seems much quicker,my friend has a stock srt-10ram,so we will have to get it on!!Will let you all know what happens.

Hey Bill,

TIA!

FYI The speed record @ Chelsea was set in 5th gear.When I had lunch with Brendan Gaughan he said the execs didn`t want to go in 6th to "have something left"

Anyone top ended theirs yet to see if it will go over 154.587?

I imagine that if the Lightning surpasses us in 2005 DC will go back to Chelsea and set a new mark.

And their full of crap too! 6th gear is .5 / 1. He would have slowed down in 6th. Viper top speed is in 5th also.

You got that right..................about the crap..............
154.54 MPH in 5th gear calculates to 5054 RPM. This would indicate that top speed is much more restricted by drag vs HP than anything else. 6000 RPM in 5th gear is 180.5 MPH. These trucks are aerodynamic bricks......they have a CD of .43. It takes huge amounts of HP to get high MPH out of these trucks. And they don't have enough to go any faster........................

Well, stock they don't, but it'd be interesting to see what Craig's TT could do on the Top End!

 

[Hemi57]

they simply need to make a road that is straight for 30 or 40 miles, and test the trucks there.

Well speaking of Craig's TT silver truck....when is he getting it back?.....Hennessy has had it since May and I am curious to see how long it takes Craig to demolish the clutch when he gets it back. I think I will start a pool on this, my thoughts on catagories were;

1. Clutch Failure
2. Transmission Failure
3. Rearend Failure
4. Engine Piston Failure
5. 180 MPH
6. The speed of light
7. Complete total
8. He will never get it back
9. Hennessy will keep racing Vipers, winning, and keep it!
10. All of the above

Lets have some feedback/suggestions on the catagories........Lets hear it!!!
