Competition Ever see a 1000hp truck spooling up?

[lmills]

I have to tell you Jetenginedoctor, the more you talk about your load dynos, the more I want to try one. Just if for nothing else, to see what the readings are like

 

[Sled Puller]

Is there a dyno that can hold one of the big hammers? Yes, I'm sure.



Has anyone been on one yet that will, and poste it here? No, they haven't.



We can blow the tires loose on Dyno Jets and Mustangs. :-laf

 

[jetenginedoctor]

Jetenginedoctor,

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

Yeah, the single retarder model 450 like what I've got will test over 1200hp.

Tires started slipping with a 530hp Cummins.

Was this your truck? Did you see this with your own eyes, or did you "hear about it?" Just like anything, if the procedure isn't followed correctly, tires can and will slip. If things like tire pressure (needs to be 50psi) are wrong, the tiedown straps used wrong, or a number of other things are overlooked or ignored, yeah, you could have problems. Show me a Dyno Dynamics machine that won't make traction, and I'll show you an operator that's not doing something correctly. Please either post or PM me the name and location of this dyno. You're not tattling if you do, you're helping me help the person that owns that dyno. It's my job to make sure problems like that don't happen.

Also that same dyno a Duramax actually came off.

Hearsay? Saw this with your own eyes? What happened? Again, a truck "coming off the dyno" is most likely a matter of operator error, not a problem with the machine. If you've got more details, I'd love to hear what they are.

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

I think saftey is something to worry about even when I'm testing a 35hp ATV. Every vehicle has it's own unique characteristics, and not every one is going to require the same testing techniques. If a truck is coming off a dyno, it's because either it's not been properly restrained, or whoever is operating the vehicle is trying to do something dumb like bounce the load cell by powershifting or some such nonsense. Again, please share more about how this Duramax came off the dyno.

Jetengine what are you calling BS on?

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

Both.

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

Thats street twin stuff.

I'd say 800hp is pretty stout, yes. How much does your truck make? Though I hate to be rude, I don't think you've got anything to laugh about. It's clear that you have no direct experience with my dynos. Unless you can substantiate your claims somewhat, your remark means very little. If you think that my machines don't work as I say, let's take the Pepsi challenge and see. Piers Harry didn't by one of our machines because they're cheap (because they're not, ask around,) he bought it because they're repeatable, accurate, and have an excellent traction system. I'm not trying to make a ******* match out of this. . . . . . . but. . . . . . unless you come back with more details about what you supposedly know about my dynos, your credibility on the issue is pretty weak.

 

[Jim Fulmer]

Once again I cracked off a number on the dyno(750#2 and 793 with water) and my truck is still a joke compared to to the big boys back east.



On the traction thing I was at 45 psi on the tires, caltracks preloaded, and 4 tie downs on the back with the wheels on the backside of the rollers and the graph shows no spinning.

jetenginedoctor

I think you need make an appointment to be at a sledpull where Schieds, Haisley, or Mitchell is pulling. 1000hp easily.

 

[MCummings]

I've worked with Brian, and his dyno is unique!



It's not like the 248c DynoJet we have down here.



Our DynoJet has very sensitive ways to tie down high HP vehicles. They have to be on the rear of the rollers, and the axle has to be tied down two different directions with four straps.



On Brians Dyno, the harder the truck tries to come off the dyno, the more traction is applied to the rollers.



A Dynojet pretty much keeps your truck from moving forwards and backwards, while Brians dyno actually holds you down onto the dyno.



As far as not being to actually "hold back" a truck... . I definatly think it's possible,,, but I think we may find that some of the sled pullers have more HP than we think... .

[HoleshotHolset]

Could you explain what you mean by it being hard to keep an 800hp truck on the dyno?

Have you ever seen an 800+hp vehicle of any type on a dyno? Heck, I've seen 600hp trucks loose traction on the dyno... Even with multiple tiedowns and all kinds of other BS (people in the bed... ) - some trucks still can't get the power to the rollers.

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?

The fact that you can take a truck for a ride and make 40psi (for example) and on the dyno only make say 32 or 36psi... on the same day!



Matt

 

[Sled Puller]

A few trucks that crank out 750 hp on Piers dyno, have only managed 575-600 elsewhere. Metric hp? :-laf



Also, exact same set ups as those trucks , back here, only dyno 575-600.



So whats the secret in dyno operating to make big numbers?

 

[Jim Fulmer]

So whats the secret in dyno operating to make big numbers?



It's no secret, I just need to make it out there for an event... ... ... ... maybe I should shoot you guys the number to the C. O. so you can influence him.



I'm more schedule driven that money driven, I'd love to spin the east coast dyno's.

Here are most of the participants from the TDR rally at Buckhorn Lake a couple weeks ago. To the very best of my knowlege, nobody had traction issues.



NOBODY.



There were a number of people who were disappointed with their truck's performance that weekend, but there's one common sentiment among all of the strongest truck's owners that ran. They were all impressed with how we could load the engine at the RPM of our choosing until the boost and EGT came up the way they wanted, and that we could set the rate of acceleration to suit our needs as well. The guys that didn't make any changes (box settings) all remarked about the repeatability as well. None expressed any concerns about flying off the dyno, spinning tires, etc.

 

[MCummings]

Mike's truck was hittin' the NOS, and man, with a flick of the switch was picking up some serious HP, and the truck wasn't even considerably moving on th edyno.



There was no rubber on the rollers, no spikes in teh torque charts, no funny business.



I dyno'd 446RWHP on our 248c here, and 430RWHP on Brians Dyno...



I think the larger chargered trucks make more HP on Brians dyno because of the load capability.



Merrick

 

[jetenginedoctor]

Have you ever seen an 800+hp vehicle of any type on a dyno?

Buddy, I've seen motorcycles that make more power than most of these diesel trucks run on a dyno, putting down all their power through ONE WHEEL. Traction problems? Not on our dynos.

Heck, I've seen 600hp trucks loose traction on the dyno... Even with multiple tiedowns and all kinds of other BS (people in the bed... ) - some trucks still can't get the power to the rollers.

See my earlier remarks about operators doing things the wrong way. Some of them will do anything they can think of trying to make traction, even the BS as you describe it. You don't have to do that junk with our dynos. A lesser dyno, yes. . . . ours, no.

The fact that you can take a truck for a ride and make 40psi (for example) and on the dyno only make say 32 or 36psi... on the same day!



Matt

Why is this such a mystery here? The DynoJet dynos you're probably used to testing on have a drum inertia that is more suitable for testing cars that weigh one half to one third the weight of a lot of these trucks. That said, there isn't enough inertia to oppose the accelerating power of the truck's engine, allowing the engine to rev-out before it can build full boost and horsepower. Unless your truck makes more than 600hp at whatever RPM you want to load the engine prior to starting the test, even my little wimpy single retarder rig can hold your engine back at full power long enough to melt your turbo into an expensive paper-weight. I've still got guys who want to drag their service brakes on my dyno. . . . for what????? Unless their rear brakes can absorb over 600hp (seriously ulikely) they're doing nothing but needlessly wearing out their brakes.



Bottom line, unless your tires are underinflated, greasy, wet, or otherwise unsuitable for being on a dyno for any reason, we can make plenty of traction. Please note that everyone at the TDR rally was testing with street tires, not slicks, not anything crazy. In fact, the most powerful truck was running highway tires. Ask him if he had any wheel slip.

Have a look. Not a lot of drama, but a lot of HP. . . .



Notice the lack of extra people over the rear axle or other such "BS?"

Jet,

You asked how much my trucks make.

Well, the old 99 makes 461rwhp on a jet and 951ft lbs.

It also did 500hp/1000+ft lbs on a Mustang (dual roller type).

The 99 also did 501rwhp and 1080ft lbs on a dyno dynamics (MY DIRECT EXPERIENCE WITH YOUR DYNO!)

My other an 04. 5 did 462hp on a dynojet and 845ft lbs.

A couple days ago my 04. 5 did 426hp and 945ft lbs on a single roller

larger mustang dyno.



My trucks are way under powered.

How much do yours make?



But, I think you are missing alot of the point here.

Were not saying the dyno will not do its job.

We are saying that it is hard to get accurate readings with some of these monster powerful trucks.

I happen to like the dyno dynamics dyno.



BTW... Its obvious that you have no direct experience with a big dog diesel pulling truck... The closest you have been to big dog power is watching Scheids pull the sled on the internet.

Come out and watch sometime in person.



Big deal you own a dyno



Don't hate the big power just because you don't have it or that knowledge does not exist in your mind (yet).

We have been through this West Coast/ East Coast stuff before.

Your just a new kid on the block around here catching up on old posts.



Besides, they're making more like 1500hp now.

You see my friend, Scheids doesn't need to get on here and brag about their power.

They just win truck and tractor pulls years long to prove it.

Got anything? that burns 5 gallons of water and 2 gallons of diesel on one dyno run?

*****SNIP*****



You have had your truck tested on one of my dynos, you have not used it yourself. Operating a dyno is direct experience. Paying somebody else to test your truck is not.



*****SNIP*****

My trucks are way under powered.

Read my sig. My truck is stock, makes stock power, works good - lasts long time. Has nothing at all to do with your unsubstantiated claims that trucks don't make traction or fly off of my dynos.

But, I think you are missing alot of the point here.

Your point seemed to be that there are traction and safety issues on my dynos. Now you're backpedaling and not coming forward with the facts. You're trying to sidetrack the issue by talking about your trucks, my trucks, the Big Bad Wolf and Red Riding Hood's trucks, etc. I think your point is you want the last word, which I'm not going to let you have. Sorry, but if you're going to spread erroneous info about my product, it's my job to set the record straight.

Were not saying the dyno will not do its job.

So then what exactly did you MEAN when you said,



"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?

We are saying that it is hard to get accurate readings with some of these monster powerful trucks.

Unless you're the elected spokesperson for everyone on this site (you're not) you would be better off to not use "WE. " YOU are trying to say it's hard to get accurate readings with blah blah blah, not WE. YOU are suggesting loosely that you know more about my equipment than I do. That's a pretty big swing your taking, be careful not to hit yourself as you miss.

I happen to like the dyno dynamics dyno.

First you say they can't hold a 530hp truck without slipping the tires (yeah, right) and that trucks fly off of them (again, I'm sure) and now you like them? John Kerry, is that you????

BTW... Its obvious that you have no direct experience with a big dog diesel pulling truck...

Hmm, I dunno. I've got direct experience with some people who thought they had a lot more than they did, and went home disappointed when their truck didn't test as high as they thought they should. Big Dog diesel pulling truck??? I figure anyone who's making twice or more the stock rated HP of their truck has a pretty respectable wagon. It's funny how you turn up your nose at the 800hp figure, saying "Oh, that's just street twin stuff. . . " Whatever. Your trucks don't make it, so you've got nothing to say about it. Just because somebody else has a truck that makes those numbers doesn't give you license to wear their success by proxy and turn up your nose. Just because your uncle's friend's cousin's adopted little brother knows somebody with an 800hp street truck doesn't mean you can talk trash about it.

The closest you have been to big dog power is watching Scheids pull the sled on the internet.

Come out and watch sometime in person.

You gotta be kidding me. :-laf



You have no idea what power is. I'm not even going to dignify you with a real response. You're pretty full of yourself, bud.

Big deal you own a dyno

And you talk trash with HP numbers by proxy.

Don't hate the big power just because you don't have it or that knowledge does not exist in your mind (yet).

We have been through this West Coast/ East Coast stuff before.

Your just a new kid on the block around here catching up on old posts.

What the hell are you talking about? Are you sober? Do you know anything at ALL about my background? I don't give a damn about your petty East Coast / West Coast crap. True, I haven't been on this forum long, but it hasn't taken me long to figure out who's full of crap around here. You make claims, now be a man and back them up.

Besides, they're making more like 1500hp now.

So what? You're not. What's your point? I never said that the trucks didn't make 1000+ HP. I said it's BS on the earlier claims that said that a load absorbing chassis dyno couldn't test them. I don't have a dog in the "who makes the most HP" fight, mine's in the "some windbag on the internet who doesn't know squat about dynos is running his suck" fight.

You see my friend, Scheids doesn't need to get on here and brag about their power.

Nor do they need you bragging for them, friend.

They just win truck and tractor pulls years long to prove it.

They must be pretty good to have diesel truck groupies like you.

Got anything? that burns 5 gallons of water and 2 gallons of diesel on one dyno run?

--Justin

What do you have that will? Talking a lot of smack with nothing to back it up. Nice.

 

[lmills]

I guess the one thing I don't understand is how your dyno is loading up the motors so they put out their actual HP, but at the same time you say they sometimes dyno less? How can that be? If you are loading the motor up so it maintains boost and fuel properly, how will it make less HP? I know of someone that dynoed on a load dyno and made more power than on a dynojet dyno. Simply because the dynojet would not allow the turbos to spool properly.

 

[jwilliams3]

Jet,

The incident I was referring to with the Duramax was back in October 03.

It was with a portable dyno dynamics.

As you have pointed out, it was a bad operator that had not secured the truck properly.

The truck made around 480hp or so.



I dynoed on your dyno HA! I guess you thought you were going to get me on that one... NICE TRY!



Whats gonna make you happy?

I have the pickups... . they make a little power. . nothing great.



So now is 1000hp possible?

You said in an ealier post is was "BS".

So now its possible? WHO is the one backpeddling?







You seen a drag bike make some power WOW!!



This smack talking kid has got you all worked up :-laf :-laf :-laf :-{}

And then:

"BTW... Its obvious that you have no direct experience with a big dog diesel pulling truck...

Stick around Bryan, you will be amazed at this little engine. twice the power is old news!



And where are the TQ numbers on that list of trucks that dynoed at your shop?

Where at? Who was the operator/owner? Again, this is not tattling, I need to know.

I don't think I know you. I'm in Texas, when have you used my dyno?

Whats gonna make you happy?

When you back what you've claimed with some fact, or stop your out-gassing. . . .

I have the pickups... . they make a little power. . nothing great.

Nothing to be ashamed of either. When I get a real trans in my truck, I'll be playing catch-up with you. . . .

So now is 1000hp possible?

You said in an ealier post is was "BS".

So now its possible? WHO is the one backpeddling?

No, what I was saying was BS is that a chassis dyno couldn't hold or load a 1000hp truck. Not sure how you could confuse this, but this should end your moment of confusion.

You seen a drag bike make some power WOW!!



This smack talking kid has got you all worked up :-laf :-laf :-laf :-{}

Come test on MY machine, we'll see who's laughing then. . . . . . :-laf

 

[jwilliams3]

I haven't dynoed on your dyno.

But, I did dyno on a dyno dynamics at the Cythiana, Kentucky truck pull back in October 03.

Scott Burton ran 1st place on the dyno with 529hp, I was 2nd with 501 (my other run was 499).

This was a portable dyno dynamics.

It says dyno dynamics on the dyno sheet.

I dont know who owns it, you ought to know.
