BIG HP numbers today in Kansas City...

Ok I do and have dynoed on a DynoJet. Here is my findings. Dynamic Dyno 634hp (2 years ago) a week after that I went 70x.x (can't remember it was barely over 700) on a dynojet. I didn't change anything as I was testing a modded fuel rail. Not sure what you are getting at by dynoing it on this or that. If you want a really low hp number go on a mustang dyno and then you will have crazy tq.

Also I have ran at the track. We only have an 1/8 mile track about an hour from me and I went 7.70 at 91 mph with a handshaker last year. That is without a boosted launch so I am think I could get high 11's this year if I went to a 1/4 track.

Now lets see if you understand a load type dyno does put a strain on a truck more than a Dynojet as they have what a 5000 pound drum once you get moving cause little resistance. AS for that truck it does run well on the bottle from the video (did good in the sled pull as well). Also you can spike a dynojet by releasing the park break in the middle of the run as well.
 
I guess you are right my dyno run took about 7 sec to go to 4000 rpm. From .07 to .14 and the video you show me of a real dyno truck took about 7 sec as well from 44 to 51 on the motor pass (not sure of rpm).

Im not one to cut down on a person (Jepling nice numbers and clean truck) but the truck you are saying is a 900hp truck has smaller turbo, way smaller sticks, and to stock pumps. So yes I guess mine is a fluke.

I quite!!
 
I believe Sloverado has the proper upgrades to support 900+ HP. 66 over Super Dave. Why are there naysayers, has Sloverado been untruthful in the past?

Real dyno, real 900hp. The length of the dyno run while under boost is a dead give away between the runs. A real 900hp run does not last 9 seconds. I'm not trying to bash you, but realistically speaking it doesn't add up and people on this site know the difference.

Sloverados truck would be OVER 921 on a DynoJet. A week or so previous to the smokin in the smokies event, Dunbar had his dyno up at an event in North Carolina. Tim Barber was there with an 04 ( 555 engine ) and made 924 on Diesel only and 949 with pure water. Dunbar said it was the highest Dodge Cummins on Diesel only on his dyno yet.

Sloverados truck is set up with the same turbos, injector sizing and tuning as Tim Barbers. Except Sloverados truck has a larger top turbo than Tim.

The dyno run for Sloverado is longer because the Dyno Dynamics dyno is a load cell dyno with dual brakes. The DynoJet of Dunbars is an inertia dyno. They are different animals.

On another note: Tim Barber stepped his up last night again. On a DynoJet.

Ryan, drive your truck up to a DynoJet in KC and git-r-done.

I am in no way claiming to i have a 900 hp truck on #2 only(770hp #2 and 903hp :nos:) but that is my goal. There is no spike in the graph it is a nice and smooth curve on all 3 runs. I will be at TS this weekend to see if my tuning has helped any. i would like to see all the high hp truck there on the same dyno so no one can *%##* :blahblah1:about the different dynos and hp readings This gets old seeing it over and over! :bang
 
Simply put, a Dynojet does not have the ability to load a Diesel truck. The data gathering uses the drums inertia as the constant, the variable is speed over time. Spin the drum up to top speed quicker, and the horsepower goes up. The only real method for measuring torque, which is the real part of the horsepower equation (torque x rpm/5252), is to use a calibrated strain gauge on a load cell dyno. The dyno also needs the ability to fully load the engine. The dual Eddy absorber on the Dyno Dynamics, has the ability to provide "real world" numbers. Why the Dynojet has become the measuring stick for Diesel performance, is beyond my rational ability to understand. Without the ability to attain actual boost numbers and fueling on an inertia dyno, power is left on the table. What everyone thinks is real are fairy tale numbers. Those are Dynojet numbers. No I am not condemning a Dynojet or an inertia dyno, it definately has its place. The truck making the highest numbers, versus everone else, truely will be more powerful. The numbers generated, will not be an actual indication of total power. Without proper engine loading an accurate result cannot be attained.
 
Dynojet is the measuring stick because if its a 248c it will have the same # in Florida as it will in Utah, it is hard to screw up on a DJ where a load dyno can be changed acording to operator inputs.

Also if you compare DJ #'s to trap speed hp calcualtors they are usually very close. i will say tq #'s are usually better on a load cell though.
 
Big Blue I have never been untruthful in say 10 years (high school days to get out of trouble). Anyone can call me anything they want but a LIER is not one of them so you can rule that out.
 
I have ran on load dyno's made by Mustang. The input required is the vehicle weight, the hp needed to roll along @ x speed. There is a rpm reader which can be plugged into the drb port of picked up off the damper using refective tape and a optical pick up.
The test will begin its test and end its test based on speed, rpm.
This method of testing simulates the street...loads the truck and lets the engine generate rpm, boost and energy.
Measurement is given based on this.

For the non believers that 921 is hoax I would venture to say its pretty close based on what I made on a load dyno 25 times and what others in the diesel world pull off daily.

If a truck wont light on a Dynojet, it wont drive worth a poop on the street . I have seen trucks with stupid big chargers make the same boost on a DJ that they do on the street when tuned properly. I have also seen numbers on a DJ be backed up with HP calcs from track runs the next day. So to say that you cant see total power on a DJ is silly. You may not see total power on a poorly tuned truck on a Dynojet, but that same truck will drive like poo on the street.

YOU ARE WRONG DON!!!!!! LOL
Tim did 924 at The Spruill Farm in Plymouth NC a week earlier LOL
 
I talked to a few people that were there and they also told me about your #'s. You got the fuel and air to make 900hp IMO
 
congrats on the numbers. dont let these guys rattle ya. put some :nos: on that bad boy and do it again!!!!
 
I am looking for a place to dyno my 2004 Raptor 660r atv I am looking to put down atleast 250hp and 500 ftlbs. Do you have any suggestions?
 
Well I for one beleive it, I know that he has lots more turbo than I do, and I put down 788 on #2. He also is running superior electronics than what I was running my last dyno day. I hit 1013 with a little spray.

Kevin
 
Im not making fun of him I am truely lookin for a dyno that I can reach it on.
 
Will you admit when you are wrong?

I know what the truck makes, these numbers are good. I will pay for time on any dyno in KC to prove it. That Guy? will you be as bold in admitting you are wrong as you were with disputing these numbers?
