Which would win in a race? I have the duramax with the edge attitude and my dad has the new cummins 600 with a comparable 120 horse chip. So what do ya'll think the outcome would be?

http://www.dieselplace.com/forum/smileys/HiHi.gif Now that is a loaded question if I ever heard one! Of course you should let your daddy win (hint, hint) LOL. http://www.dieselplace.com/forum/smileys/Evil Smile.gif Good to see a father/sun tandem out there in diesel land. Both trucks are respectable units and you both will spend lots of time looking at gassers eating diesel fumes in your rearview. Drive safe. JJ

Which version of the DMAX do you have? Are both auto's or handshakers? Even with more power, you have to be pretty good with a handshaker to win a short race.

Similar to my set up, I have an 04 4 door dmax short bed with edge, my brother just got a 04.5 with the banks set up, 4 door, 4x4 short bed.


He smokes me and its pissing me off. He lights them up out of the hole and I can't get close to him. Don't know if its the edge not making enough (mines the 125 unit), or his banks is better.. On the freeway at 60 its even worse, when we both kick it, by the time i spool up, he's gone..http://www.dieselplace.com/forum/smileys/Confused.gif

Yeh that is what i figured would happen what is the deal with Our turbos?? How is it that the fixed turbo on the Cummins spools up so much faster than our VB Turbos??

I do not like Dodges but the Cummins is a very serious engine to be dealt with. It is problay the stoutest diesel you can buy in a stock pickup today and if very overbuilt even for current power levels. GM needs a new ace in the hole to pass that thing long term.

http://www.dieselplace.com/forum/smileys/Confused.gifAm I wrong in thinking the 35 inch mud tires on his daddy's truck is going to make it harder getting the power to the wheels? SDaver, from what I've read on your other posts that ain't no "truck" you are driving, more like a frickin rocket. Other old farts like me: Did you ever imagine you would be in discussions about "diesel" trucks and 1/4 mile runs, 600HP/1200TQ, stomping Vipers, vettes, etc? Yaaaahhhooooooo! http://www.dieselplace.com/forum/smileys/Thumbs Up.gif

Okay duramaxtom I have a suggestion,


When you race from 60 DO NOT floor it as you would a gas engine reaching for "passing gear" The stock Allison/duramax simply will not react. Damn thing may go into a temporary defuel mode and you never know when the truck will take off. Try this: Ease the throttle to the floor just fast enough to NOT go into the passing gear. IT worked for me when I was stock. I saw this idea posted over a year ago.


Also, You need the Attitude 145hp and ability to regulate defuel.


And then a tranny upgrade and etc.

gmaccall: tried your thought last night, at 60, eased into it, he still kicked my ass. we went over the the giant diesel station afterward, and he's 200 heavier! now I'm really po'd. then we went out on hwy99 and did it again and again, i could only keep up with him if he dialed 2 and i was at level 5 on the edge. when he went back to 6, it was like i was going backward..

The boost is controlled by the tune. You really need to drive a truck with the TTS Tow Tune in it. Nearly instant power, both off the line and from a roll. Stack it with your edge, and he will be suckin Bowtie smoke.

Gray Max

I got smoked by cummins when I was running stock this winter. I think he was stock because he didn't run away, but he had me pretty good. I won't let that happen again.http://www.dieselplace.com/forum/smileys/HiHi.gif

Do you have an LB7 and are racing an LLY?

nwpadmax
08-05-2004, 10:21 PM
Wolf, from a dead stop, were you power braking to build boost?

Also, are you running the Alli in normal or Tow/Haul?

I find that my truck seems quicker from a dead stop than rolling into it at speed.

60 is kinda slow anyway....mine runs hard up about 80 http://www.dieselplace.com/forum/smileys/Big Smile.gif

Wolford
08-06-2004, 12:31 AM
We didnt power brake them. I also found out which chip he has and it is the TST power max but he has it set on hp level 3 and torq. level 4 he still has the stock tranny and cant go any higher than that. As for me I was on Edge level 4 with defuel on all on and in the normal tranny setting.

The TST puts pretty decent power to a CR cummins.

EMSi
08-06-2004, 08:59 AM
I don't think you will touch a Cummins 600 with a TST Power Max with an LB7 and just an Edge Box - might have a fighting chance with a Hot Juice but thats what my buddy has on his 305/555 and like I said it is really impressive. Especially if he can get the power to the ground - I know the 6 speed will spin the clutch on the higher settings of that 555 and its rated already for some serious torque. http://www.dieselplace.com/forum/smileys/Cry.gif http://www.dieselplace.com/forum/smileys/Broken Heart.gif

If you want to kill the transmission in short order, get yourself the TST PowerMax and the Predator, stack them as high as the truck will allow. You will need 5th gear lock out, then give er hell. If the Dodge Cummins still out runs you, then don't be upset because at that point he must be in the low to mid 13`s


I had this combo, and run a 0-90 in 12.2 seconds using the G-Tech Pro Comp. I did not have 5th gear lock out and limped the tranny pretty good just past 90, so I did not get the 1/4 mile time. I would bet that if the tranny would hold this, these trucks would run low 13`s at 100-102 mph. And guys like mtomac would get it into the 12`s

duramaxtom,


Did you ever run your truck with a g-tech through the 1/4 mile? I like the Banks 6-gun, but level 5 on the Edge and level 2 on the Banks shouldn't be even.http://www.dieselplace.com/forum/smileys/Disapprove.gif

I like the idea of getting together at steel on night and runnin the piss out of 'em. Yeh but my attitude defuels on level 4 5 because of tranny slip and i have not installed my egt probe yet but will do soon.

I ran a red '04 CC/SB Powerstroke 6.0 with an Edge Attidude on the freeway yesterday. At first we were both stuck next to each other in stop-n-go traffic and I saw he was puffing a little each time traffic moved. I saw his dash-mounted Attitute and said you're smoking up the place, and he said it was like that in Level 5.


Anyway when traffic opened up just North of Escondido we slowed to about 30mph and ran em up to about 85-90. I pulled him about 2 truck lengths, with me on the TTS 120hp setting and him on Level 5.


Afterward I wondered whether he had any tranny work done because he was pulling hard all the way.

I wonder what were to happen if I were to go into a Dodge or Ford site and go to a post asking who would win btween truck a and truck b and I were to say absolutly nothing about the actual topic(witch truck is faster) but instead say "what you guys drive has a long way to go, its at the bottom." http://www.dieselplace.com/forum/smileys/Ermm.gif They would probably say what i said is a bit trollish and trying to get a reaction.


You ussually do your best to dodge any of my direct questions and you refuse to give any examples when you spew forth flat out bad information(I'm not talking about your oppinions, everyone is intitled to them) so i figured asking you to quantify your statment about GM needing a new ace was pointless so I figured I'd be a smartass. Or are you going to tell us GM is getting rid of the duramax becuuse all of its problems?

Wolford

I am from North Alabama close to Huntsville.


I like the idea of going to steel and burning all of the gassers.


But I have another Q. As ya'll already know I have juice w/tude and I want put in the TTS tuner everyone is talking about. Which stage tranny would I have to get to hold the 120 TTS and the 150 Edge?? OR is it even possible to hold both chips at their max output. And also can my stock turbo handle this kinda power.





Right now my alli is stock and i cant take the edge off level 5 (it is to addictive) but i dont usually gun it.

DMax_Doug

Wolford,


Most everyone that does tranny work at all seems to go with the Transgo kit plus a triple-disk converter, and some add new clutches.


I'm one of the few that went for less, getting the Transgo kit and Suncoast billet single disk converter (Stage 1) and I've not slipped or limped it once with the TTS 120 (or Extreme so far). Now that I'm doing some racing, I'm planning some upgrades but if you're looking to not go beyond 120HP and don't race or pull, I can attest that the Transgo kit, a good aftermarket single disk converter, and fresh clutches (if yours are burnt) will do the job nicely.


Doug

I dont think that the TTS 120hp is out yet for the LLY nor the HOT edge. I would prolly go with stage III trans !

hdmax
08-07-2004, 01:12 AM
If you don't race, don't pull, and don't go beyond 120 over on horsepower, then I don't think you should waste you money on any type of transmission upgrade.


But that is just my opinion. and it is your money, so do what you want and or can afford.http://www.dieselplace.com/forum/smileys/Approve.gif

Wolford
08-07-2004, 11:16 PM
What is the Hot edge? My edge w/tude on my LLY is 150 horse on level 5. I will no longer be using level 5 (I limped it pretty good tonight show out for some people). Until i get my tranny upgrade im not going over 3 or 90 hp.


Or at least i think i limped it (would turn 3,000 at 55 and wouldnt shift into 5) but all i did was turn it off and let it sit for min and then started her back up and she ran fine.

Such a child.... I have driven diesel powered truck for overs 15 years on and off (6.2's 6.5's, 6.6's 6.9's, 7.3's & 5.9's) and the Cummins is the only one still around today that was also present back then. If Dodge did had not had the Cummins back then, they might not be in bussiness today because their trucks sucked otherwise. Even today I would not own a Dodge but I can respect the engine in it that they do not make but it "makes" their truck. Mark my words though, GM is replacing the current Dmax in a few years. My sources tell me 07 or 08 at latest and it will be a outsourced engine. The name "Cat" has surfaced a few times. Heck I even driven some of the 350 Diesels based on the 350 Olds engine when they where out and my nieghbor had one that he swore by for 140,000 miles (a lot back then) until the motor toasted in the mid 80's.Edited by: snoman

The duramax is actually a joint venture between GM and the largest diesel engine manufacture in the world - Isuzu, and some US made electronics that are the same as what is on the oh so mighty common rail dodge.

hey next time your out raceing the cummins lock it out of o/d. run at 60 then take off then unlock over drive. to lock out the o/d just hold down the tow haul mode for 5 sec and a light will come on in the dash. same thing to take it out.


butlocking o/d out should give u the advantage now because your rpm's are up and the turbo in boosted.

Do you have your low boost set to level 5 on your edge? I am curious because you said it takes a bit for the turbo to spool up as if low boost was set low on your attitude.

in a few years thier might be a new d-max from isuzu maybe a 6.? or a 7.? but i dont think gm and izusu would make a 6 or 7 year long deal. it really wouldnt make any sence. use a company for 7 years and start looking for a new one. whats wrong with all of the current d-max's? are they not strong anough? their right their with the rest of the comp.


i think your source might be talking about the kodiak line or something. like the 6500-8500 serries. they might get ride of the 7.8 d-max. that might make more sence.

My low boost is set on level five, I really didnt see an improvement over the stock setting on this feature.


Also does yours blow out much smoke if it is in P and u hit it one good time cause mine doesnt and that makes me think that the low boost fueling isnt functioning properly.
