Your stroke got just barely ranked above gas the same truck in a gas burner in a loaded tow test and so i find it hard to beleave it maintains speed well loaded. Not to mention my brother has one for his work truck it gets horrible mileage unloaded can't imagine trying to maintain speed loaded with it screaming rpms this comparing it to his stock 06 cummins. Both 250 and 2500 autos 4x4 4door short beds.

 

If you notice, he never mentioned anything about it being loaded at the time. Maybe he's just happy it doesn't actually lose speed on hills when unloaded.

 

Sure, start the discussion but when it gets too involved you're suddenly too tired to respond. Although not too tired to write this long post and fire off another 3 or so responses to others in the same thread.

 

Whenever I get flack from the Duramax crowd, I just send them this link.

Oh man that was hilarious!

Hard to argue with the video proof. I guess in the real world there are other important variables besides HP, weight, and gearing. None of that stuff matters if you're tranny and engine are overheating into limp mode.

That Dodge looked bone stock too. Just imagine how bad the DMax would do on some real grades in Utah with 105* ambient temps.

 

Well if I was part of that duramax crowd your referring to I'd send you a pics of a leaking 53block, a pile of junk vp44's, junk injectors that dodge won't warranty. Do a forum search for "dropped valve seat" and look at the carnage. Personally I'd take a cooling issue over a junk head,piston(s) and most likely cylinder(s) and probably turbo...... when one of those decides to let go. I'm not saying the d-max is a better engine, but I'm not going to throw them under the bus when neither brands are without their faults.

 

Are we talking about 3rd gen or 2nd gen Cummins here???
Far as dropped valve seats I don't think it's very common on stock engines.

thats would I was thinking, everybrand has there share of pro/cons and some of these guys need to realize that, its fine to be loyal to a brand but some guys take a back seat to logic just to state there brand is better

 

Surely not common enough to have it's own website...

CoolMyDuramax.com

lol

 

It doesn't matter which generation, they all have their faults. Just like the duramax. One year of the duramax had cooling issues (as you've seen) another had issues with injector cups and injectors. Funny though out of all the things people on these forums have predited would be the downfall of the d-max when it first came out hasn't been an issue, aluminum heads. On the issue of the cummins valve seats you'd be surprised how many have this problem brewing and they just don't know it. A friends shop was rebuilding an '06 mega (bone stock) that melted #6 due to a bad injector (imagine that) and while it was apart he had the head checked and about 1/2 of all the valve seats were loose and had to be replaced. I bet that my '05 has the same problem but until they die or you remove the head and check them you don't know.

Logic has no place on these forums. It always seems that everyone is competing to be the biggest blind brand loyal cheerleader. There must be an cheerleading awards ceremony and the winner gets a cummins t-shirt. (I know some of you just got all starry eyed)

 

i like the cummins, but it gets so old listening to all the brand bickering. everyone needs to accept the duramax/ally is a great motor and tranny as is the cummins. not everyone needs to love it, but why all the bashing? the only person that should be really concerned is the trucks owner, because they are the ones making the payment or filling it with fuel. duratothemax...you were adding some great info for the OP by giving him some tips on winning. and usually keep your head when all the back and forth goes on. i would be happy to drive either truck. i wouldnt be caught buying a ford though

looks to me like you own a 6.4l......or....no you dont.

My truck loaded holds speed it just takes a little more boost. even stock it held speed plenty well.

Anyone in the denver/ft collins area of Colorado is more than welcome to bring a heavy bumper pull (i have no gn hitch) and we can go up floyd hill or something right off I70. thats a mean pull.

None of you own one yet you bash it. The magazine may have put it down but to be honest i dont really care. a V10 tried to outpull me on my trip to texas this weekend and i just let the cruise do the work. My truck never shifted down but i could hear his truck screaming for mercy.

My truck did about 15-16mpg coming back from texas yesterday. From Denton, TX to South Fork, CO which is going from about 1000ft altitude to 8500ft altitude, rarely going below 75mph. Ill take it.

You dont own one. you are a magazine boy taking whatever the magazines say bad about the Ford or GMC and using it against them but if they say something bad about the dodge you will just say oh well my friends uncles sister has one and it doesnt have trouble.

I had a CTD before this truck. The CTD no doubt has more low end and pulls trailers better but this truck has no problem holding any speed up any grade.

The only thing ive read about anyone having trouble holding speed was someone with a stock F450 pulling 18,000lbs up a 6% grade only being able to do 50mph. Id like to see your stock cummins pull 18,000lbs up a 6% grade doing anything much better than that using stock tuning.

 

Gotta love these cheerleading threads!

Powerband, gearing & weight make or break any vehicle's acceleration, loaded or not.

My 8L V-10 outpulled our '97 12V by a WIDE margin, and didn't get passed on the road 'til the HPCRs showed up.

I like the area under the curve enough on my '05 that my son never had to ask twice for the keys to the '98!

It's all relative... when the CR race truck is finished, I might not even bother keeping Smarty loaded on the '05.

 

Back to the original question, If you get the smarty beta 4.4 tune and a good fast shifting clutch, and you can shift(very fast) then you should get em. It will be a close race right off the line and halfway through. But once you get to reaching higher speeds, you should start pulling on him. Our Cummins' have a wicked top end. The duramaxes will start giving up at higher speeds. Yer gonna have to launch in 4wd though to keep from frying your back tires. I would very quickly repeatedly rev it to between 2500 and 3000 rpms and dump the clutch in second gear in 4wd. That should get you off the line. That duramax is gonna launch hard if he does a boosted 4wd launch.

If you really want to embarass him, then get a better lift pump and stack a tst or an mp8 with it, and you will really blow his doors off. Let us know how it turns out.

 

well what else would you like me to say? Theres nothing left to argue, I posted my side and Justin posted his.

I dont feel I have done anything stupid here to warrant a sarcastic response. Its probably not often a duramax guy comes on a CTD forum and ISNT an outright a(*. I respect the ctd and I have always said I do.
