Competition duramax puts down 1000 hp

[JRamirez]

The BullyDog dyno rated me within 20 Hp of the Dynomite Diesel Dyno. The DDP is a Dyno Jet. We will be at the Dynomite Diesel Dyno day in May. I know Damien put up very similar numbers at Edge Days last summer.

Oo. Oo. GO GO REB GO Oo. Oo. But the Cummins back on top with the D :-laf :-laf yno Wars

Why drive all the way to a gasser trash/gas station/shop garage dyno??

Duh, Bill, to be the first 1000 hp duramax, thats why.



At any rate, its a respectable number, dyno queen or not. I cannot imagine driving anything like that on the street even at 500 hp. My 250 hp truck is a handful on anything but dry pavement.....

I know from what I have read the last vid is with the last motor not the 1000hp but what is up with 2 12. 6or so runs then the last 13. 51 wow that is alittle inconsisent to me I have see dmax drag and never seen one that inconsistent.



Now to the 1000 hp dyno vid what is up there the turbo's barley get whistlen and the vid stops if that is all of it that is not no 1000hp dyno run.



And the reason CR dodge aren't up there is plain and simple programing. You have some one design efi live for the CR's and dodge will take over all over again.

It was the first time to the track and it was run on a single cp3 when it went 12. 6. For the 13. 51 run I was driving and had been up for about 42 hours straight by that time. To say I sucked at the lights would have been a understatement. I was dozing off in the staging lanes.



If you knew much about dynoing you'd know that the more hp you make typically the shorter the run. From the time you go full throttle to the time peak hp is made is only a couple of seconds.



As much as I am a Dodge guy I dont know for sure if the Dodge will keep up simply due to cu. in. The Cummins is only 89% of the displacement of the Duramax. Overall durability will most likely always stay with the Cummins especially for long term at high hp but for short term race or pulling motors the Dmax will be a contender. Another bonus for the Dmax is the amount of aftermarket parts or more correctly the rate at which they are being made. There seems to be way more effort being poured into it then the Cummins. Dont get me wrong, I'd still like to see the Cummins be the top dog but you can not overlook the potential benefits of the Dmax.

very true, dyno runs are very short and cubic inches make power. it may take a while but people will get the aftermarket side of things rolling for the CR's soon enough. good job on the d-max guys.

just lots and lots of tuning and trying different things i guess. i know he was one of the first if not the first guy to have a CR motor with that much power. i know hey dynoed last year with 893 with No2 but he should be close if not past 1000hp this year and it should be on #2 only but dont quote me on that. he is also trying some VERY VER innovative things on a TURBO diesel engine. i am a good buddy of his and told him i woudnt say much about his truck but you guys should now him, Richard Brown, or better known as REB. he only lives 5 miles from my house and has helped me with my truck ENDLESS times. i just cant wait to see it on the dyno at the end of march.

im quite sure reb will dyno many times before march... ... ... some one will leak out the info soon enough.

No question, hard parts are seeing a lot of attention in the Dmax world.



My opinion is that once the performance pistons are ready, we'll have everything we need to shove the crank out the bottom of the block. Everything else seems to be fairly well addressed. The fuel and air are readily available, and the tuning ability is extensive.



So for me, I just wonder what the limits of the main bearings and block are.



With good tuning and the rpm available, should be able to put up some good numbers.

 

[Idaho CTD]

I think the bearings are going to be the first hurdle. It's one that can be easily fixed though. With 4 bolt mains keeping the crank in shouldn't be a problem especial with upgraded fasteners. Splitting blocks might be a concern though. You can make block stiffeners as well though.

Your ET doesnt start until you go through the beams so your statement doesnt make sence unless you did not build boost up at the start?

Thats because there were more exploding duramaxes at around 700HP so something had to be done for all the people trying to make decent HP with them. At that HP level the majority of cummins motors dont need to go that far into the motor with custom aftermarket made internals.



Im not claiming that its wham bam 700+ HP out of either motor, there are alot of things needing to be done to support tham at that level but we all know the internal strength of the cummins is superior which all boils down to less things needing to be addressed internally to be a survivor at that HP level. Im not saying the Dmax is a poor motor design at all! Its a very impressive engine and there are ALOT of them making their mark in the diesel performance world.

i am sure of it to, but he dynos at a local dyno and is really trying to keep it hush hush. have i seen what he is workin on and on his truck? YES and i would love to tell trust me just becuase i think its innovative and going to be freakin awsome but i also told him i woundnt say a word . . either way, 1000hp truck is flippin awseome i dont care what brand it is.

 

[RobertP]

HP wise, the LBZ motor is much stronger than the others, i know of several people that are using these blocks and some are even converting electronics from one model to the other. this should be a great year for the dodge and the d-max. once " EFI LIVE" type of programs are complete for the dodge, it will all boil down to how strong the motor is, and while i like the d-max i still think the dodge will come out on top. due mostly to the stronger block and head, even though dodge has less CI and 2 less cylinders.

now quarter mile wise, the d-max has a big advantage being lighter and having a factory 5 and 6 speed auto. so it may be a while before the new dodge 6 speed auto is able to be built up, and hang with the allison

I only built about 5psi instead of 18-20 like I should have. Typically with no boost you'll run 1. 5-2 seconds slower then leaving with the optimum amount of boost. In this case leaving with 5psi I was a second or so slower then when Keith ran the truck.

I agree with that. Dmaxes need better rods from get-go and it looks like the billet rods are very very stout.



One thing that I think was poorly understood and not widely known was the cam gear pin drive. I have a gut feeling that more than a few Dmaxes let loose because of it and it looked like other parts and/or was misdiagnosed. Now the new cams pretty much have that resolved as far as we can tell.



I guess I look at it more that the Dmax isn't necessarily "weak," it just not built as tank-like as the Cummins. It's amazingly overbuilt for a doggone pickup. I'd love to own one but I'm not a big fan of debt out the wazoo.



Maybe someday they'll all have a choice of Cat/Detroit/Navistar/Benz/MAN and we'll all look back and laugh at the "dinky" motors we used to run!

A different driver would make sense on the 13. 51 run.



But on the dyno what I was saying is the turbo's if you listen on the vid never get spolling all the way to be pushing 1000hp twins or not. that why I ask if that was all the vid because as soon as the turbo's started to whistle the vid ends.

I have noticed now that it is a probablem with the video it stops running at 3/4 though. so that is what made me think is wasn't to great of a run but I did notice that the truck shift once the dyno run starts.

It is the typical ladder or whatever you call it, COMPETITION, "I'm the best, then their the best, I'm the best, then their the best, etc. "



That's what makes the power wars so fun to watch.
