There is a class in western Pa that is close, it called Tough Farm. 7k and 8k weight classes. 360 In3 max, 3000 RPM, 3LM466 turbo (or similar), rotary pump etc.
There are currently four tractors running regularly with others in the works.

The answer is it depends, you would have to do a dimensional stack up to make sure the rod is properly centered in the piston and that the crank cant move far enough to cause the rod to hit the radius on the crank. You might be able to put the engine together and move the rod back an forth and move the crank the opposite direction and make sure that you have clearance between the rod and the radi

It depends on how the rod is constrained, is it made to use the crankshaft flanks to control the location or is it made to use the inside of the piston to control rod location? Most people expect the rod location to be controlled by the flanks of the crankshaft, but it doesn't have to be.

Is the VE pump original equipment?
Why the VE pump instead of Stanadyne pump?
Thanks

By class rules, maximum displacement is 360 Cu In.

I am going to push for limits based on inlet and exhaust outlet size, not stuck to one turbo.

Our class rules require the use of a "box stock" 3LM466 on our 5.9 Cummins with a rotary pump at 3000RPM. We are having a hard time spinning the turbo to get off the line and at the end of the run we go under the turbo. We also are running high exhaust temperatures. It is my belief that this turbo is not a good match for this class and I do not believe my competitors are actually using this turb

For comparison, our 1850 is at 6200# with the cast tub, straight shaft, no PTO, no hydraulics, 18.4 x 38 tires with steel wheels, straight front axle, aluminum fenders etc.

Thanks for the offer, but I am looking for a HydraPower (2 speed).

I am looking for a good hydrapower for an 1850 (1750, 1800, 1850, 1900 or 1950) if anyone has one for sale.
Thanks

Claim rules have been tried in local motorsports, but it doesn't work there, either the guy refuses to agree to the claim in which case he is baned from further competitions with that group. Another approach is to have something no one else wants, why would an IH guy want an Oliver engine or a fuel pump that work on his engine?

The advantage to the orifice method on fuel is the simplicity of enforcement, no measuring required, pick a pill from the tub and put it inline with the fuel supply, no muss no fuss.

Turbo rules and limits are fine, but those are routinely defeated and end up with expensive hybrid turbos.

The idea was to have a "limiting" function that could be easily monitored, similar to the RPM chips that are used with ignition systems.

Different engines use different pumps and making everyone change their engines to use the same pump would be prohibitive, in my opinion anyways.

On the charge pump or supply pump might be a good approach, it should help reduce the cavitation issue.

That is an approach, unfortunately the only way to know plunger size is to disassemble the pump.

The point about cavitation is a good one, I will have to give that some thought, pressure drop through the orifice might cause air to come out of solution or create a pressure below the vapor pressure of the fuel.

There have been several attempts to introduce entry level diesel classes at a local level with restrictions on injection pump type, turbocharger, tires etc. Inevitably the class rules escalate to allow the use of better pumps, better turbochargers, better tires etc. The one idea I haven't seen is to limit fuel flow with an orifice on the inlet to the injection pump. A properly sized orifice

I do in Antiques, but I always felt I was at a disadvantage to 18.4 x 38s.

Does a 3LM466 turbo require an orifice (restrictor) on the oil supply?

Loudonville, Ohio Street Fair tractor pull is Oct 4 this year. Right now we run what we call Modified Farm Stock at 7700; 10500 and 12000 lbs. We also run a 8 MPH farm stock at 13000 lbs.
That is good news, I hope to bring our Oliver 1950T to Loudonville this year for the 7700 # Modified Farm Stock.

Good point, of course the tank wouldn't be pressurized until the engine was running.

Is it possible or reasonable to pressurize the water tank with turbo boost and then use an electric pump to help push the water? This approach would require a solenoid valve to prevent water injection under low boost conditions.
