The brakes are not locked, the tractor frame rotates around the rear axle. Take a scale model tractor and notice that the axle is directly above the point where the tire contacts the table. Now lift the front end 45 or even 90 degrees and note that the axle is still directly above the tire contact point because it is the center of rotation. There is a torque at the axle where it is rotating th

Assuming the angled hitch is constructed right, I would be on the side of hitch angle makes a difference in one force of pulling which would be the chain and sled with tractor "at rest". So lets say you have a plain straight hitch, put brakes on-on the tractor with sled hooked up, now sled backs up (lets just assume it has the power to do this and leave that out of this), As i

One way,
There is effiency of using the fuel and air you have. Valve timing, piston bowl geometry, compression ratio... More RPM's also means more CFM.
I know nothing about their setup, but if it's 2 stages I doubt the boost is anywhere near 400, that would be a very high pressure ratio.

Rebel Red,
I think you are hitting on the fact that our society has changed a lot over the last 30 plus years.
30 years ago the best athletes in school played 3 sports (and sometimes a 4th in the summer). Now, you have 'optional activities' year round in all sports, this zaps all of the athletes time and for those to young to drive, their parents too, getting them to everything.

I personally don't like the any sheetmetal rule, but I wonder why everyone gets all excited about it in tractors, but there is never mention of truck classes that have been that way for a long time, including the diesel truck class where fans are very brand/engine loyal. Some of the diesel truck guys even advertise it in their trucks name.
IMHO, if any pulling class is like F1 it would b

The angle of the frame does not affect the calculations and although the factory hitch points are not the same on all vehicles, the vertical distance is always tire radius minus hitch height, and the minimum horizontal distance is always in the rule book, so presuming that everyone is at the max hitch height, minimum distance back, and are running the same tires, they will be the same.

There is one more thing to consider that I didn't look at yesterday, that is horizontal force at the hitch point. This is the force that makes the sled move & for it to be equal the front axle weight must be the same as Doug stated. So, I think the question is, can the Deere do anything with the extra 200 lbs of rear tire force if they are given the extra 200 lbs? IMHO, all other things b

I have attached my spreadsheet of calculations if anyone wants to review it or use it for their own application. This is a simplified calculation in that it ignores the slight horizontal movement of the CG (center of gravity) as the front comes up. To make that calculation we would need to remove the weight of the parts that don’t move as the vehicle pivots around the rear axle (wheels, tires,

My opinion is generally no. A lower CG (center of gravity) will help with stability, but when it comes to balancing the forces it doesn't matter where each weight is located, just the horizontal location of the overall CG which is directly related to the weight on the front axle.
There are several forces affecting the tractor; the CG of the tractor, the chain force on the hitch which tra

If the competitors are running all of their weight on the nose and can't run full hitch height, yes. Otherwise, no.

All valid points, but also the wider the track width the more stable it will be and less likely to 'walk the dog'.

I'm confused on the turbo rules. The alky is straightforward, but the 470 gets a bigger charger than inter cooled 410 and the little twins have to run smooth bore?
What exactly is a "forward facing MAF'?
1-1/8" deck plate? Who needs one that thick?
What is meant by "Valves must seat in the bottom of the OEM head on all 6-cylinder engines."?

I've been considering 4-1/8 bore x 4.4 or 4.5 stroke. But a 359 might be a better option since it would not require destroking. If you don't mind me asking, were you able to get flow you are happy with on your 359 without moving valves and which head did you use?

Have you done a compression check? If timing is that far off I would think it it would show up there.
Are you just wanting to check the timing marks or use a degree wheel?

First, in most LLSS classes compound turbos are only allowed on 315 CID and less diesels. The reason for that is a 315 generally can't spool the 3x4 turbo buy itself so they are allowed a smaller turbo to make the 3x4 work.
In general compound turbos are used to generate high boost pressures. If you put 70 psi of boost into an automotive V-8 I don't think the block would hold it.

IIRC that one was kind of like Bad Medicine mentioned above. It used an OEM rear end housing, but it was from a powershift tranny they were allowed to remove which left the ending and rear connected by only the frame.

If I understand correctly you want to put the fire ring outside of the sleeve top flange? As JD Diesel said you need something to back up the fire ring, it will stretch out until it hits something solid and I don't think a copper gasket will stop it. A SS gasket will provided there is enough material left between the bores. How much bigger is the flange than the sleeve OD? I think you re
