Competition Ever see a 1000hp truck spooling up?

Thanks, TDR Staff

Competition Red Dually... wheels up!

It's a good thing that records can be reset as fast as they are broken... the bar keeps moving it's like trying to hit a very fast moving target!

Hmmm,I dont think you'll ever see a full blown pulling truck on a chassis dyno.



I agree with John. It's hard enough keeping an 800hp truck on the dyno... nevermind a 1000+hp truck. Pulling trucks run chargers so big that a chassis dyno probably would not be able to load it down enough to build 'race trim' boost levels.

my turn to pull a JW3 :-laf



What about a big rig dyno? I've heard that their load capabilities far exceed those of a regular pickup truck dyno?



Heard of a truck that made 100 MORE HP on a big rig dyno loaded to only 60% than on a regular pickup dyno. :confused: :-{} :-laf
 
I didnt necesarily mean a pulling truck I just meant maybe we can see anyone make 1000 hp on a dyno since some people dont beleive 1000 hp is possible but know the bar has been moved to 1500.
 
Lets see what I can do.



I'm not shooting for the 1,000HP. That would be nice.



My goals for my 12V are, minimum of 615 on fuel, and 300 more HP on the giggle bottle.



If I can pick up my fuel HP,,, I won't have to run as much bottle.

I saw one a couple weeks ago at Kauffman's Fall Brawl. You are right about not getting a good load for the charger. They had to drag the brakes to get it to build up enough boost. The guy put down a 789/1440 before his back wheels started slippin'. Pretty darn impressive. If you wanna see some pics, check out this thread:

I would have to dissagree. The Smith Detroit Allison shop has a dyno that they use to dyno all thier semi's. I think it can be done with the right type of "load dyno"

I was at a buddies shop when they were breaking in a 2000 HP rail car and his mustang 250 would bring the car to its knees.

Jetengiedoctor was talking about a AWD load dyno for a 4x4 application. So all the drag racers out there and pullers could see how much power they have in 4WD.

O ya... Forgot to add that MADDOG2 (Richard Madsen) was on the same dyno... He had no problem with wheel spin. I can't remember off the top of my head but it was more then 725 HP.

In my opinion most diesels dynos read high because people still erroneously use normally aspirated SAE hp corrections. I believe that 1000 + hp is very possible, but not in drag racing form, I give up a lot of hp to run chargers that will spool in the short amount of time available. The 1000 hp truck in the video would work in a drag setting if you let it set and spool on the line for 15 to 20 seconds. I really don't know if a transbreak will hold that long, and would the converter boil the fluid out by then, I have to change my Trans fluid every 3 or 4 passes now. I believe that contrary to most diesel peoples belief, lean is mean and has the ability to rev gain better then soot black, with just a hint of gray haze. I have not got to that point with mine yet as I believe the pair of chargers that Ken built me from Turbo Auto Diesel are still making more air then the amount of fuel I’m letting it have. I still have around 6 mm of rack travel left before I max out the pump, but I have a lot of work to do still on the set up before I turn up the wick. I don’t believe that I‘ve exhibited a 1000 hp yet. The pass at Dallas did not put a number on the score board, that best represented the amount of hp the truck was truly putting out. I’m guessing a number in the high 800 to low 900 range at about 4000 rpms , anyone here care to take a guess at it, 2934 lbs and 8. 72 @ 154. 44 it lost a intake gasket 3. 3 seconds in to the run loosing 25 lbs of boost
 
Justin,even with the semi dyno or the baddest load dyno. you still couldnt chassis dyno the baddest of the bad pulling trucks. No load dyno will do it.

John,,, you know what you just did right? Somebody is sitting at their PC right now going,, "Hmm, Oh Yah,," And he'll say,, "Hold my beer and watch this"...



It's going to get down now. LOL

I'm going to have to call BS on this thread, guys.

:) I'm not sure where you get this idea, but you're very sadly mistaken. Piers Diesel research has one of our twin-retarder single axle dynos that will HOLD a 1200hp vehicle at any speed you want long enough to seriously smoke-check the engine. It'll test a vehicle up to 2400hp. Not enough for you? Got something meaner. . . . . ?????



Dyno4mance in Calhoun, GA (www.dyno4mance.com) has one of our AWD dynos with twin retarders on the rear axle. This dyno can hold an 1800hp vehicle at any speed you want, and can test up to 3600hp. Still not enough???



St. Joseph Diesel in St. Joseph, MO is talking to us now about building a chassis dyno capable of testing 2500hp pulling tractors. Don't think that it can be done? Don't be so sure, because just as soon as you crow about it on the internet about it being an impossibility, somebody will make it happen and make you look pretty bad. That 'little' Mustang 250 dyno that Justin was talking about can and will put a pretty good hurtin' on most every truck owned by a TDR member. Our big multiple retarder Dyno Dynamics machines will absolutely crush whatever anyone on this forum can put a license plate on. The pulling tractor dyno will have to be custom built for St. Joseph Diesel because of the enormous diameter of pulling tractor tires, along with the high torque and relatively low wheel speed that are inherant with these rigs. But you can be assured that if somebody's got the money to pay for it, we can build a dyno tough enough to test just about anything. ;)

Could you explain what you mean by it being hard to keep an 800hp truck on the dyno? Also, what makes you think that a chassis dyno can't apply enough load to build "race trim" boost levels? Am I missing something here? :confused:
 
Jetenginedoctor,

I have seen and dynoed on a Dyno Dynamics dyno that was supposed to be rated for up around 1000hp IIRC.

Tires started slipping with a 530hp Cummins.

Also that same dyno a Duramax actually came off.



I think safety is one thing to worry about once one of these pulling trucks gets lit.



Jetengine what are you calling BS on?

The 1000hp+ thing or a dyno not being able to hold one or load one?



Jet you really think 800hp is big dog stuff? :-laf :-laf :-laf

Thats street twin stuff.
