Competition Been beat by a Duramax yet....

[StakeMan]

Now I no why you kick my butt at the track.

CCannon,



Those are some amazing numbers!



How is the Duramax holding up under that sort of power? I am surprised there is that much "untapped potential" in the engine given the Japanese engineering penchant for designing at the margin (i. e. , making things no stronger than they have to be for the intended purpose, to keep cost & weight under control).



When I was looking for a used CTD, I was leery of getting a truck that had been BOMBed and hot-rodded to death but figured the Cummins was tough enough that I wouldn't have to worry too much. Would a fellow looking at a used Duramax have more / less to worry about in that regard compared to a CTD? Just wondering... .

To answer your questions about durability and reliability I cant tell you. I have pushed this truck as far as I can os far. I thank there is more to tap. The common rail is full of potential, we have found it. The truck has been built for pulling loads and gets plenty of race work out along the way. The aluminum heads have been a controversy, I feel the heads help a lot with heat dissipation. One thing we are having lots of success with is the EGT's. At the end of a quarter mile run at full fuel the EGT is right at 1500. My dodge is at 1500 at half track. Time will tell us alot more about the reliability of the little Chevy engine.

Clint,



Nice numbers, however I need a little clearification. StakeMan started this thread talking about injectors and propane only. No boxes. So my question is, is that 512hp on #2 only with just these injectors? or is that with the boxes, injectors and all the rest of the goodies, but still #2 only?

 

[Diesel Freak]

Clint, what is the correction factor on that dyno? My top speed on the 1/4 is 91 MPH... with a six speed manual.

 

[Mike Ellis]

Thanks Clint,



Darned impressive no matter how you slice it, not bad for a "pile of melted beer cans"... ... !

the '03 Dodge ISBe is warming up......

Shrimpy touched on this. Only after 2 months of R&D The Diesel Dynamics '03 Dodge is @ 444/839 #2 only... of course.

The 512 hp was on #2 and injectors along with a race version of the Power EDGE juice. One advantage the juice gives is no de-fueling between shifts. One HUGE advantage I have is the transmissions ability to not slip, this was a major problem before we came up with the fix. When the transmission would slip the computer de-fuels causing low power. The injectors are a key secret to the power.

I talked to Jay, he owns the dyno. He told me the numbers were not corrected, but then he said you could add about 20% to them for correction for altitude. I thank the whole corrected numbers thing is for short people. All I can say about the dyno is it seams to be repetable. When we ran the same vehicles at may madness the numbers were almost identical on this dyno. (not the Duramax). When I ran the Duramax at Atlanta speed way the best quarter mile time was 13. 4, the best time in Denver was 13. 5. We have not seen a lot of difference from 5000 to 500 feet. The average between all of the trucks was about 2 tenths. As far as the mph it is usually about 98 to 99. I have the speed limiter removed for racing.

 

[Diesel Freak]

what is the weight of the truck with driver?

 

[Diesel Freak]

My truck weighs 7150 with a full tank and me in the drivers seat.



using ET (15. 955) I get 348 RWHP

using trap speed (90. 91) I get 419 RWHP



averaging the two 383. 5 HP



the truck dyno'd at 370 HP

Couldn't help it, but is the same dyno Don dyno'd his Dodge on just before May Madness? Wasn't their a huge controversy last year?

Yes it was the same Truck along with Craig’s 98 12-V and John's 24-V. The numbers were within 10 HP of the mustang. Don's problem stemed with the design of the inertia dyno. The load dyno gives torque info the inertia does not, that is what Don was up in arms about. Get the BD Duramax going yet.

Simply Awesome Clint

I was so impressed with ALL of the ATS trucks here in Atlanta. Clint really seems to have a handle on the Allison transmission and getting the power out of the Dmax. I saw his 13. 4 pass and if he could have kept the front tires pointing straight it might have been a 13. 0.



Clint, you will need to make a few passes with all of the drugs to see what you can get that ET down to.



We have put the juice box on many of the Dmax powered GM's at the shop and they are impressive. I dyno'd a 2003 last week with only the juice at 315hp on my dynojet. Just before I dyno'd a 2002 Dodge 2500 with EZ and 275's and she went 285hp. Right now in my eyes, bang for the buck goes DMax.



Congrats on the numbers Clint.

 

[Cooker]

David,



I'm not trying to discredit your numbers, but I would have imagined the Dodge to crank out a few more ponies than that. Every truck is different I guess.



I wonder what a box will do to the 03 Cummins????

 

[Huff N Puff]

Just something about the Cummins

Just something about all the iron in the Cummins,that is comforting. Just something about 6cyl that makes all that power. The Duramax with all that aluminum and steel just dont sound too durable to me. Time will tell,I'm betting on the Cummins.

Don's problem stemed with the design of the inertia dyno. The load dyno gives torque info the inertia does not, that is what Don was up in arms about. Get the BD Duramax going yet.

I think we could debate this comment on till the cows come home, but since we have a mustang and are possibly looking at getting a dynojet, you could assume that we have researched the pros and cons of each. And the inertia dyno does give torque info.



The problem last May was that Don's truck was supposedly putting down huge numbers according to this Mustang dyno, only to be disappointed when he got to Diesel Dynamics. While everybody else that dyno'd was pleased with the accuracy of the results, Don was the only one disappointed. Anyway I'm getting off topic, the dynojet according our tests has been more accurate for measuring torque and HP above 500 HP.



As far as our Duramax, 3 months ago we got it going a 14. 0 at 96 mph, this truck dyno'd 410 to the wheels. It seems you picked up 2 mph for 160 HP.

 

[StakeMan]

2 mph and . 5 second change.

 

[Mark_Kendrick]

I'm pretty sure the truck has seen a few changes since Atlanta.



BTW I asked Clint about the #s and... . they are uncorrected::--) :--)
