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?

That sounds a lot like a class in western Pa that has been called Tough Farm.

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.

I tried to watch the race, but found it difficult to follow. Next year they need to have it as a night race, that way the cars will not be going into and out of shadows, it would also make it better for the drivers to see.

The formula for area is
Diameter x Diameter x 3.1416 / 4
5 x 0.013 holes equals 0.00066 in2
4 x 0.015 holes equals 0.00071 in2
So the 4 hole have slightly more flow area

There were different options for the transmissions, your best bet is to take the serial number and go to the AGCO parts site (Google it) and enter as a guest. It will not be easy to decipher but you should be able to figure it out.
