The one thing I have not seen being considered is the fans at the pull, everyone is talking about this from a competitors standpoint.
The fans want to see a local tractor compete, they want to see how a local guy stacks up against the out of towners. The promoter knows this and likely decided to make an allowance so that the local guy could compete. Having the local guy pull exhibition is not

There are some good looking 20.8 x 38 tires in the for sale ads, that have quite a few stress cracks or perhaps dry rot.
Is there a repair for these defects? Perhaps an epoxy or caulking that will stay in the defects?

I pull with some IH's with DT360s in similar weight classes but limited to 3000 RPM, but they are using 656 and 706 frames, they run as high a 25 MPH, which works out to 24:1 final ratio. I am not sure that helps you very much, but it is a data point.
Do you think a 400 rear end and transmission will hold up?

Very well written.
Who trained you?
Who trains new flagmen?
I believe you are correct that most venues grab whoever is willing to be flagman.

I bought one through Ebay, it is a stainless weldment and seems to work OK, if did come from China and delivery was weeks.

In our local club, the flagman is part of the show and has a fan club in his own right. I do wish he would keep more distance between him and the pulling vehicle.
There are other local clubs that use a red/green light tower controlled by the sled operator, this has the advantage of not having a flagman on the track and also allow the sled operator to stop the pull if something is wrong. Howeve

I do not have a suggestion on how to determine what classes need additional rule restraints or how it should be determined, I was asking the question because I do not know how to make this decision. My background is engine design and failure analysis and I do not see a clear path to making this determination other than historical results.

Another side of this safety discussion should be to what classes do the proposed requirements apply?
One suggestion was anything over 2000 BHP, how would this be decided?

I am not a novice to pulling, but it has all been on the local level. As an onlooker, unless there is an easy visual difference between the classes, such as Modifieds versus Super Farm, I cannot tell one tractor class from another.
I do not like a class where are all of the competitors are within inches of each other due to an aggressive sled setting that drops the "anchor" at the end of the

I know what OEM means, the companies you mention are great companies developing new equipment, which is great. The fallacy is assuming that eliminating OEM components will eliminate parts launching into the crowd. The sport will keep demanding more power and the new stuff will eventually fail.
At least I have the guts to post my name and where I live, people making inflammatory statements and

You keep saying to eliminate OEM components,
How are you defining OEM component? Any company that makes a component is the OEM for their component. So if I build an engine from scratch, I am the OEM, so it would not be legal??
How do you guarantee that a non-OEM component is good enough or necessarily better than an OEM component? The only way to know is to perform component analysis and

I agree with the inline comment.
I do not understand why a V engine would not require a tether of some kind, can't a similar failure occur with a V engine?

I watched the videos, the part that is missing is fatigue strength, which takes expensive equipment and lots of time to evaluate. Without fatigue strength it is difficult to make an evaluation of fasteners and their ability to do the job we need. High tensile material does not necessarily result in high fatigue strength, it depends how the fastener is manufactured and the heat treatment of the ma

There was an antique puller that pulled at Tunica that had a van with a cable lift to open and close the ramp. I do not know the specifics, but the cable let go and the ramp fell on him, putting him the hospital. The year I was at Tunica they were doing a fund raiser for his medical bills.
The reason I mention this is as a caution, if you are going to use a cable lift, make sure everyone stays

It depends on your goals, if you are OK with 230 F intake air, then using engine coolant will work and many engines are done this way. Take coolant from the discharge of the water pump, or use a dedicated pump and take coolant from the outlet of the radiator (usually the bottom).

I talked to a young man running an IH666 and a 3LM466 turbo this weekend. He said the 3LM466 turbo was too big for the 312 and he added a restrictor plate between the exhaust manifold and the turbocharger, he said he got the idea from a posting on PullOff. I am curious on the theory behind adding a restriction between the exhaust manifold and the turbocharger. I can see that it would raise the ex

Also last we checked into it. There wasnt any diesel emission standard above 700 hp.
I worked for GE building diesel locomotive engines, these engines range from 1250 to 6000 hp and have been regulated for emissions since the 1990's.

Usually an orifice is used to reduce oil pressure to the turbocharger, I am not sure what size is right for your application, it will take some trial and error to determine the right size.
