I just crunched some numbers, his run took 13 seconds, and he went at least 300 ft. That's about 16 MPH dragging 40,000 lbs in the dirt That is absolutely incredible. God knows they probably had the spikes dragging on him, too...

 

schied truck has twins van haisley is running the same motor Dan schied said there are eight of those motors out there

 

Banchee

When are we going to see that black truck of yours doing that? I know deep down inside you want more power just like I do!

I know your looking at this thursday AM when you should be working to make my job easier

How-bout next time you see me stop and talk, don't worry about QA they can wait. like we wait for all you engineers!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You guys who dont believe it has 1000+HP have never seen it pull apparently. When that thing comes off the line, its just unbelievable. I dont need a dyno sheet to believe this one. Also, you guys that question it have never pulled a sled apparently. Those things are heavy, and you have to get wheel speed, and momentum going to pull one very far, and that is something Schied has for sure. BAD truck!! Youd have to hear/see it in real life to believe it.

Preach on Brother ERIC!

 

There's no reason to think it CAN'T have at least 1000 hp. There are guys like Jim Fulmer making 800 to the ground and only turning ~4000 RPM (I'm just guessing here, I've seen a picture of his tach BURIED, so )

These guys are coming off the line at 5K+ and probably hittin' 6K by the end of the track, so it only takes 1100 ft lb of torque to make 1000 hp.

Also, good luck getting a dyno sheet, I doubt there's ANY way to get their chargers to spool, just ask some of the guys here with big twins. (Again, I'm just guessing on that, but I'm probably close.)

Have at it guys,
Chris

 

This is the main reason that I can believe the 1K HP claim^^. It's not just the power, it's the RPM. Think about how much air it must take to maintain 80-120psi of boost at 6000 RPM!! NOw think about how much FUEL is being burned to make smoke with that much air!

Now, think about how much MORE air that thing can take in because of the insane camshaft.

That truck moves a LOT more air than another truck, even at the same boost and RPM levels.

NOW, factor in the insane boost and insane RPM levels and be astounded.

Good Point's, HOHN. I was kinda worried when I saw you name pop-up, I thought I screwed something up .

To see the amount of air he's moving, just watch how high the smoke goes compared to everyone else's.

I just wonder if he's using one of their 12 cylinder injection pumps? Those thing's are , too.

Chris

 

he not using a 12 cyn pump

 

I would love to know what his piston (super sonic) speed is? I cant believe that at 6000 RPM!!! the piston's dont fly right out of the heads.

 

The stroke is just about a tenth longer than a Reher-Morrison 622" BBC (4.72" vs. 4.625"), so the piston speeds are not too crazy.

Stock Dodge @3000 RPM - 2360 feet per minute
Assuming this truck has stock stroke then @6000 RPM - 4720 feet per minute
Aforementioned 622" BBC - 4625 Feet per minute
350" SBC with stock 3.48" stroke @6000 RPM - 3480 Feet per minute
2.2 liter Honda S2000 @9000 RPM - 4950 feet per minute
2003 BMW Formula 1 engine @19,200 RPM - 7874 feet per minute

Now that is crazy!!

 

Jim Fulmer making 800 to the ground and only turning ~4000 RPM (I'm just guessing here, I've seen a picture of his tach BURIED

I typically make max HP around 3100 and hold just a bit longer to see how it holds out and come off the throttle slowly that gains another few hundered but I always make 3700-3800 by the time it's all over.

Jim

 

WOW, I stand VERY corrected, but that makes the point even better.

Thanks, Jim!

Chris

 

Not to nitpick (though it seems I have a rep for that, lol), but......

These are AVERAGE piston speeds. It appears that you have just taken stroke length and multilied by RPM to find speed. It's not speed that matters, though. It's ACCELERATION.

This is determined not only by stroke length and RPM, but also by ROD length, or more accurately, the rod/stroke ratio. The rod length divided by the stroike length is a ratio that has a huge impact on the engine's operating characteristics. Ratios around 1.4-1.5 are considered "low". Ratios over 1.8 are considered "high".
There's a LOT to be said about rod ratio, and I've posted at length on this topic (featuring links to GREAT tech writeups from my bud "Panic").

The other factor that places piston "speed" in context is mass-- the weight of the piston.

F=MA

So the force acting on the piston (which is what will determine failure and conversely, durability) is a function of PISTON ACCELERATION AND PISTON MASS.

So, a piston with half the mass can accelerate TWICE is fast for the same amount of force. Get it?

That's why all the examples you posted above really are apples to oranges comparisons as you didn't post the rod ratios or piston weights. It's safe to say that the BMW F1 engine is optimized for screaming RPM with a very high rod ratio, and very lightweight pistons.

Oh-- one other comment.

There are a LOT of trucks over 1000 lb-ft in a CTD. It's not news. All you have to do is make 1000lb-ft at an rpm higher than 5252 rpm and VOILA-- you have your 1000 hp.

The high RPM is the key to the big HP numbers.
