Just to be clear I leave the line at approx 4500rpm get traction and travel down the track at approx 5600.

The problem is that it is nowhere near 40,000 lbs when it starts out which is what Sleddy has been spewing over and over again. The wheels are a pivot point so the sled can change the effective load with the same weight that it left the line with, basic stuff.

You just contradicted your ownself in a few sentences!
I don't CARE if the sled weight 5 pounds or 500,000 pounds, the WEIGHT does NOT change from one end of the track to the other.
The resistance does,as you move the weight from the wheels, to the pan.
Damn, I step out to go pull a motor and look what happens here Please know my intention was not to start a sled pulling vs drag racer war here. I have made up mind and I am going with billet rods that have been proven in a modified sled pulling truck. I asked Steve if his rods were in any modified sled pulling rigs and if he would have said yes I might have looked at them but I am not comfortable nor have ever been with being the first to try a product.
With that being said please carry on with the pissing match :bang

So Dale's rig is going to be a two wheel drive, does that mean he will only be putting down 50% of the power when compared to us 4 wheel drive folks :hehe:

So the load starts low and increases steadily as you go down the track which is just what I said to begin with. The problem is that it is nowhere near 40,000 lbs when it starts out which is what Sleddy has been spewing over and over again. The wheels are a pivot point so the sled can change the effective load with the same weight that it left the line with, basic stuff.

Something else is most of us cannot shift so we are taking off in a gear higher than most drag trucks and most drag trucks are less than 8000lbs right and since you are a big dmax fan hows come they don't run in a unlimited single charger class or bigger just wondering
DT your talking about 1400 hp. but Scott is making considerbly more than that (and part of his problem is he is considering adding more power)and I think that needs to be factored in.Some of the top pulling trucks are up to 1900 hp.
The other thing is without getting into a debate on breaking driveline parts----
"""wouldnt it be alot harder on an engine when you start at high RPM and drag the engine down (no matter the gearing if you are dragging the engine down the strain is on it)sometimes till you snuff it?"""
When you drag these engines down (@1900 HP) the strain would have to be huge compared to spinning the chit out of one going through the traps.
Again each have there own issues to overcome but the question still remains will the said rods hold up in Scotts engine?I am fully aware you need some strong a$$ parts in a drag race engine but the original question was what is the best rod in Scotts application?
Now you've got it Scott!!So Dale's rig is going to be a two wheel drive, does that mean he will only be putting down 50% of the power when compared to us 4 wheel drive folks :hehe:

If you look at what Scott posted he starts his run at 4500 and ends around 5600 RPM. As engine speed increases at these speeds torque output decreases which makes it easier on the engine. Now if you were able to drag an engine of his level down to lower RPM it will break itself as the blocks will not hold the stress. This is why everyone is running them filled or going to billet blocks. So if you were able to drag it down to peak torque output you would reach max load for the engine crankshaft. Once the RPM drops below peak torque the crankshaft load is going down again so it's not as simple as snuffing it. The worse point on the engine is operating at peak torque.
When you drag these engines down (@1900 HP) the strain would have to be huge compared to to spinning the chit out of one going through the traps.
The strain is maxed out once you reach peak torque output, above or below that point the load on the crankshaft is less. For the record most diesel race engines are operated above peak torque RPM points just for this reason.

. Your BS claim of 40,000 lbs at the line is just that BS.

http://en.wikipedia.org/wiki/Tractor_pullingToday's sleds use a complex system of gears to move weights up to 65 000 pounds..........
Northwest Pa Pullers, a sled that NWPADINKYMAX has hooked to more than once, weighs in at---ouch---maybe I shouldn't say this- 42,000#+.
