Speed Shift

In the newest issue of Diesel Power, ATS built a D-max that makes 970hp. It has a custom crank and aluminum rods.

Does anyone know of anyone machining the crank on a cummins, or lighter pistons and rods??? I have never heard of it on a Common rail. My question is WHY NOT? We are going to need these parts to keep up. Turbos, modules, nitrous, and other bolt on adders can only go so far... We need hard parts that make these diesels a true race engine.

I am talking 1000+HP. It is possible, it just needs to be figured out. I am sure it is out there we just need to find it. Do the 1000+ 12 valves have parts like this.

The parts I am talking about are...

Big Aluminum or steel heads(huge ports, oversized valves,ect)
Stronger lighter crank shafts
Stronger lighter pistons and rods
Oversize bores

They said they took 10lbs off that crank on the D-max! I know these parts need to be strong but they can be built lighter. All we have to choose from are stock lower engine parts.

I am just looking forward to the next step of diesel performance, to see just how far we can go....

Have you not seen the thread in the 2nd gen performance forum??

970hp Duramax dont have nothing on this truck:

The next step is already there...its already been here while

You need to check out www.enterpriseengine.com, www.scheiddiesel.com, www.haisleymachine.com, columbus diesel supply, riverside engine, etc. etc.

The parts are already out there for your info. All the $$$$ you want to spend. The sky is the limit.

Dont belive everything you read.

I've seen that truck in action at the DHRA Houston event. He snapped a u-joint and then the ring and pinion I believe. It was a very impressive truck and had a nice haze at idle and sounded wicked spooling up. I'm inclined to believe that they weren't lying on numbers.

Thats what I am talking about! Some crazy power!

I just want vendors to distribute the kind of parts it takes to make that kind of power. So, when someones askes what "mods" do you have it just wont be "a fuel pump, turbo, module, and some NOS". I want to be able to pull this motor down and build a monster.

In order for this sport to grow we always have to want too much.

Im in Colorado and I've seen that at several events, probably every one its been to in the past year in colorado...i do doubt it.

They didn't build that truck to last 500K miles, they built it to spin crazy RPM and put up huge HP. The big players have been doing stuff like that for years.

Think of it this way... if you own a DMax and see that truck in the magazine.... well not you specifically, but most of the sheep are gonna think, "wow, if ATS's DMax can do that then their products must be pretty good." Everytime someone buys one of their transmissions, turbos, heads, etc. they pay for some of the cost to do that. Heck, I bought their transmission and exhaust, but that was because they marketed better a few years back than the other builders. In fact I didn't even know of any others until shortly after I bought mine!

I'd be willing to bet that if you wanted parts like that and had the $$$ that ATS, Scheids, Haisley, or Enterprise would gladly set you up. Those parts won't ever be on the daily drivers because the cost cannot be justified. Come to an Ohio or Indiana pull and you can see all those neat, expensive parts in action. You may even get to see some of them break!

Like the other's have said its nothing new making that kind of HP. Many builders have been doing it for years.

Its just a magazine bro. They just make it seem like its all new and revolutionary and will do an article on anyone who pays or onyone that can sell more copies of their magazine.

There's no one to blame other then the big guys not stepping up to the plate and get their trucks and companies noticed by the genral public. I dont know what their problem is. If I had a shop that put out many 1,000 hp pullers and dragster you'd bet id be calling all the magazines to do an article on my truck, shop, and products. Maybe they see it as selling out but I just see a missed opertunity.

Since the diesel truck market has just peaked there still are many new people to the sport that believe everything the read in magazines and have no idea that's there a whole nother community of people out there with alot more knowledge and a whole lot more HP.

Haha I still think its funny that a few guys entered into the challange with a Banks PDA.

And I couldnt believe they let the D-max guys "cheat" and get away with it on the MPG test. 25mpg city/highway/mountians/ect COME AWN!!!!

I think the guy with the banks pda was a backup for a hot 7.3 that got into a wreck right before if i remember right, even still i think they could have done better then that for a backup!

I dont expect this stuff to last forever, I just want the parts avalable. I know 12 valves have been doing it, I am talking the common rails. That certain d-max is just making my point to say, "they have it why don't we?"

Im really just saying I wish we had more parts to choose from, one day we will get to the point where we will need them to stay competetive. The newest program isnt going to cut it forever for us, big power is made mechanicly....

runamuk

I'd have to agree with you whole heartedly! Up until now locally I'v only seen 12v's making over 700 rwhp with stock lowerends, no aluminum heads, no hot rod lifters....Y?

Build it and they will come

Well the reason most people don't do it to the common rails is because it's not needed. There really isn't any reason to modify the crank or rods when you currently can't get a CR engine to rev fast enough to justify it. Unless your like Ted Sterner and put a p-pump on a couple.

acook

Yeah i think the first thing we need is some custom tuning for these trucks...
