Currently Im running H<130> rated michelin tires with a set of pirreli scorpions on the way which IMO after running a top heavy 06 at 140 on stock factory wrangler tires I only noticed a minimal gain in response, and have you ever taken a pickup above 90? or are you speaking from a numbers perspective because any Modern 2wd truck handles fine at high speed Ive even seen F250 with huge nitto mud tires and a 6" lift run people at triple digit speeds with no control problems, and stopping quickly? If your racing through the city like a moron it doesnt matter how big your vehicle is or what kind of brakes and rotors you have your not going to stop quickly which is why you see kids wrapped around power poles in their tuner cars all the time.

Also not to sound argumentitive or get in a debate but the mds does slow down your acceleration with the factory programming wether it says it on paper or not. I driven several dodges from different gens with different engines and with and without mds.

With the 09's ability to engauge and disengauge the MDS its clear on the road that it does slow it down also I dont have the exact measurements of city blocks I was using it as a general reference but those are the results Ive gotten.

As for Car and driver and the rest they have a close resemblence to all other magazines they blow more smoke up your *** for the advertiser thats paying them the most and I have yet to see a test with the settings that I ve indicated so at least to me their testing holds no validity.

As for racing tundras and lightnings

A lightning is a supercharged v8 its at another level, supercharge a Ram and the lightning wouldnt even see the tail lights.

As for a racing tundra's unless they have the totyat supercharger <which again puts it in another brakcet> a tundra is nothing. An 09 out preforms a tundra in ALL handling aspects and Ive beaten 3 - 5.7L tundras rolling and from a stand still, 2-3 with confirmed disabled traction control systems.

As a disclaimer Im not even all that thrilled with it and ill most likely trade it in for a Srt / Rt challenger by the end of the year but I kno what it cant and cannot do.

 

Well I'm glad you can beat the numbers posted by the pros. Maybe you should start working for a magazine or a racing school. A stock Tundra 5.7 is faster than a stock Ram Hemi, even though the Ram has a higher total HP figure. It comes down to power band and transmission. Maybe those tundra owners didn't know what they were doing.

A stock ram won't hit 90 in under 2 city blocks. It will take over 1/4 mile to hit 90.

Driving a 6,000+ lbs truck at 140mph is not really safe anywhere. It's fine in a sports car - like a Corvette, but in a huge truck, it only takes one small mistake to spell disaster for you and potentially everyone else around you. Yes, I've had Dodge Rams over 100, but I wouldn't take one up to 140 - they don't feel solid at 105. My vette felt more solid at 150 then a Ram does at 100.

And lastly, MDS does nothing to slow you down under WOT. You must not understand how it works. It only comes on under very specific circumstances.

 

I've been following this thread and a couple of points need to be made:

1. The MDS only is activated when there is little or no load on the engine, therefore when your foot is mashed to the floor the MDS will not be activated or affect your performance.

2. The torque control management is what makes the truck feel sluggish when you take off, that's why you can't spin your tires or why an almost 400hp truck won't throw you back into the seat when you nail it. This is how Chrysler can offer a "lifetime warranty" on the drivetrain. If you can't abuse it, it should last.

You'll have to wait for an outfit like Hypertech or Edge or whoever to come out with a programmer to cut back or reprogram the computer to allow less TCM intervention or you can have a custom tune done. But remember if you load in an "out of the box" or custom tune and you break something internal in the engine or trans and the dealer scans for codes and sees a non Mopar approved program in the computer, then my friend, you've just flushed your warranty down the drain. This isn't so common with the gassers as it is with the diesels, but you should be aware of this.

3. If you really want a go-fast truck, just add a supercharger. Yeah, it's a hell of lot more expensive, but you'll get more bang for your buck. How much performance will you get from a $500 mandrel bent exhaust, a $300 - $400 open air intake set-up, $500 - $1000 on headers, (and if you live in California, long tube headers are non-CARB compliant), and maybe a $400 - $700 hand held programmer? What have you picked up maybe 0.5 - 0.75 of a second in the quarter mile and maybe 1 second to 60mph? You're already half way to a supercharger, most of those are CARB (California Air Resouces Board) approved, come with their own programming - so now you can walk-the-walk and not just talk-the-talk.

 

I agree with points 1 & 2 and partially so on 3. With a CAI, exhaust and an Edge programmer (spent right under $1,100 total) I shaved about 2.2 seconds off of my 0-60 time on my '07 QC Hemi. (I didn't compare 1/4 mile times). While I think a supercharger is a great idea and fully support anyone going that route, that most definitely voids your warranty and is a large up front cost. I reprogrammed my truck before it went into the dealer, so I was "safe" and still had my warranty, which was important to me.

 

wow guys lots of great useful information.

I do believe that mds does not have nothing to do at a full stump to the floor pedal. I believe it only cuts it cylinders off at a low load as stated.

I have to disagree though on this. The ram is very stable at 105 mph. There is complete control over this truck. I have no problems with it. Does it seem to ride as smooth as a vette hell no. It's a truck for geez sakes! I have ran this truck many times to its 105mph and it is a very smooth truck. It is not safe to do these speeds anywhere except on a track!! I don't care what kind of car or truck it is. My old 5.9liter on 33's controlled "alright" at 100mph. I was very concerned though holding it there. lol It wasn't near as smooth as the 09.

I cut the esp off for the first time today and gave it a punch. Got some tire spin and took off. Didn't really rev it up or anything. Depending how much gas I want to waste tommorow I will try to run another 0-60mph with it off.

How bad does it spin from the start with the 3.92's just from a stump? Is it bad? My 3.21's had a little spin and just went. I am wanting to know how much tire spin the 3.92's cause. Just comparing.

Thanks again for all the info. I wonder how much an intake, programmer, and exhaust will wake this truck up. I am very curious in the programmer in what they are shooting to change and the shift points and everything. Truck should have some real ***** once the aftermarket parts hit stores.

What programmers should we be looking for in your past experince that will be better for the dodge? edge,superchips,diablo,ect....

 

I agree these trucks should handle 100mph no problem. I had a 2500 5.9 cummins that I got to 110 without much problem and there's no comparison to how it drove and how this 09 drives.

What rpms were you hitting at 100mph?

 

I have 3:55's and it doesnt spin to much when you pu it to the floor just grabs and goes but it will smoke if you bring it down hard but a few inches from the floor.


at 100 I get around 5-6,000

 

I never said the truck can't handle 100 or 110 - yeah, it'll get there and it'll do just fine if there's noone around you and no turns up ahead. But, try swerving to avoid a deer that runs out in front of you or someone who decides to merge into your lane ahead of you and it'll be a different story. Or, try taking a few turns at 100 mph. A sports car can still handle those situations with ease - the Ram won't and that's why I made the comments.

 

Swerving around deer and going around curves going 110 is no problem in these trucks. They have electronic stability that can defy the laws of physics

 

WOW no comment, not even going to get started on that one, another statistic is all....hope you test this theory out on your own and cause no harm to others...
