Competition Duramax engine issues

somehow I think if it windowed the block the same replies would be posted.



Its the fact that it made 1000+ Hp, not how reliable it will turn out to be...



Someone already said it. How often does stuff break on a dyno vs. on the strip or hooked to a sled, and its already puking coolant.



I would get some runs on the track with it at 1000+ before I got out my pom-pom's



$0. 02



I agree anybody with some cash and knowledge can lay down a 1000hp on a dyno if they don't care about the longevity of the engine. lets see them pull a watson and run it for a season.
 
Even if it grenades tomorrow, that's still very impressive. If they break at that power level, then maybe they can figure out why, and correct the problems one issue at a time. . The person that posted the numbers, did say it was a little early to compare with the likes of Maddog. They said once it prooved reliable, the could then start to compare to him. . I thought that was nice to say. . The biggest question I have for now is, what was the correction factor used? That can make a huge difference at these power levels. . I hope they were uncorrected. .

It be funny if it's also been "corrected" to be 1000 Flwheel HP :)
 
I want to see the graph :-{} I read that it down shifted and spiked to 1000hp . so whats up why do people start threads and not have to goods posted.



I rolled 1200 on my john deere rider yesterday,but I lost my graph. . :-laf

SWEET!!!! I love it..... that is almost as good as my Dads buddy's 55 chevy in the living room. He said that him & his wife always enjoyed watching movies in his car... . so he brought the car in the house & they put a projection screen in his living room.

I think you know the answer to that one, Rod.



;)



Apparently most of the folks on the DP want that to be a cheerleading-only thread. If you watch the video, it's blowing a lot of steam at the end of the run. The owner stated that the injector cups (which are a LB7-only issue) were "lifting" and letting gases into the coolant channels in the head.



I asked a few questions and it was like I said the emperor had no clothes.



And until someone teaches me how you can diagnose internal motor problems without disassembling it, I say there's no way one can determine if it is injector cups or head gaskets.



I wasn't trying to be chief dark cloud or spread doubt, but many are already yapping about taking her to the "next level"... .



The truck is built like a dragracer, not a puller, so hopefully come spring we'll see how it lasts on the strip.



I agree!!!



Another thing is it was on a Dynojet 224 with a load brake. You CAN NOT compare those numbers to 248C numbers!!!!! ;)



I have personally seen trucks that did 450-500 on 248C's do 700+ on a 224 w/brake with no changes to the truck. The 248C numbers were closer to what the track times indicated! :eek:



Like I said in that thread, if it's truely putting down 1000, it will do high 9's to low 10's at the track. Unfortunately, my gut tells me it won't get out of the 11's ;)
 
I'm pondering posting a thread over there:



"dodge diesel does 1500hp and streetable with stock turbo!!!"



And scan in hand drawn dyno graph, or claim it's was lost when the computer crash.



this is all great that this guy did 1000hp. But yeah, like dockboy said, if his 1/4 mile times don't back it up... .



Will we get the ricer/ford mustang excuse of "I didn't have the boost turned up, or my starter it acting up?"
 
It sounds to me like they were letting the truck shift on the dyno. This is what Mark Broviak said on the Diesel Place "The funny part about it is this truck defuels to 500hp to make the shift. Our LLY is almost putting that to the ground at full tilt. "

Yup, if it was my truck, I would have found a SuperFlow with twin eddy current absorbers to run it on (the ~1500 hp AutoDyn). I've been on the little brother 700 hp version once and it's unbelievable how for a couple seconds that thing is literally absorbing everything the truck can possibly make. Foot buried to the floor and the motor rpm doesn't change. That's a load cell test!



Now if I had one, I'd let it do its normal thing and run it up to the rev limiter, but I'd make it draw the motor back down. Bring the thing to its knees like a pulling sled does. Then take a look at the area under the torque curve.

:-laf Now that would be simply evil :-laf I love it!



It'd be funny as hell but I betcha your post wouldn't last two minutes. Maybe we should take a poll on it and see what happens. :D

I couldn't agree more , I have done bolth but the load seems to be (I think anyways) more beleiveable. there are to many factors in just spinning to win
 
nwpadmax, I read that it defuels down to 500hp in between shifts, being a chevy man your self would you call that streetable or just plan annoying? All I can think of is whiplash going threw the gears and going from 500 to 1000hp what 5 times?
 
Take it for what it is. All that is really known is that the Duramax engines are now getting some hard parts and big numbers are being had. The real proof of the pudding will be this summer at the track and pulls. Now only if the Ford camp can step it up we would have even more fun! Competition only makes things better. :cool:
 
whats up with the signatures over there. they sure as hell like thanking people.

they think there nascar racers after winning a big race or what???
 
i've been quiet and i give credit where credit is due... so congrats on 1000hp on #2 with a Dmax.

but seriously tho, you cant say, its a streetable 1000hp and he drove it home, because im sure (and prove me wrong if in fact i am) that he prolly detunes it to about 700hp when pulling his trailer home.

i am also one of those who wanna know how they figured out where the coolant/pressure cam from without tearing the motor down, as well as where are the graphs. when you make this kind of power and everyone starts bragging and posting, you cant NOT post the proof. I'd really like to see what the graph and torque curve look like. I'm not saying it wasn't done or that its not true, I just wanna see the graph.

we'll see how it holds up when the racing starts in the spring. and also, i wonder when a Dmax with 1500hp on #2 and water will come out to start pulling with Brad Ingram, Van Haisley, and those type trucks.
