7030 for super field

I pull that class with the Missouri Mule D21 and you will need some wheaties (700-800 hp) to compete. head work will be a must and 466 cubes would be best. I am not there yet. an 11mm pump minimum, 12 better. need to run 22-25 mph to be competitive. I am running around 22-23 mph and placing 5-7 th place usually. Doyle

Better get rid of the power director to it won't like 800 HP.   My power director in a 7060 won't hold any more than 4th high at 10,000 pounds. I successfully ran 5th once on a slick track after a rain.   I tried 5th a couple times after that and warped the clutch disks.

I doubt you will get anywhere close to 22MPH or 700 HP with a 10mm pump. Just not enough fuel to make enough power to do that. If they limited the turbo inlet to something a lot smaller than 2.8 or a GT42 there would be less need for oversized A pumps.

I read the rules for the 9500 pro field last night. They are identical to the 9000 hot farm other than you can use a P series pump and you can use 20.8 X 38 or 24.5 tires in the pro field class. Not much more money for a P pump than a good A pump. If the plunger size rule isn't enforced you will see that kind of competition in the hot farm class anyway.

The clutch will be an issue unless your play by the 10mm rules. If you stay legal, you should be fine if you use a 7580 clutch. If you go faster I would guess you will need to figure out how to manufacture a hub and engage both sides of the clutch at once.

I know a guy who runs limited pro with nwmtpa, but I would like to run with iamo since they are more in my area. The Shelby, Mo pull is only a few miles from me. There are a couple hot farm tractors running in the pro field P pump class too I have seen. Wish iamo had a 12mph class for me to start out in.

Wonder what this dude is using for a clutch? No shift on the go.

The upshift on the go shift is beneficial on pace tractor classes. The downshift usually equals the end of the run or close to it. When the HP gets high enough an on the go shift is no longer possible. Even the high output IH T/A will only handle so much. After that its pick a gear and run it.

I would assume he is using a shorter radiator and running the air intake pipe over the top. I think a straight shot into the inlet of the turbo is a good thing. Huge HP gain - no, but you will gain some.

Notice the exhaust manifold.

Looks like a steel manifold similar to what I was talking about building? Looks like it's glowing hot.

I see a lot of pulling tractors with 8 lug aluminum wheels on the front. What are they using for hubs/spindles? Ide like to use 8 lug on 6.5" aluminum wheels such as on a chevy/old ford/old dodge pickup. I never have paid attention to them on tractors ive seen.
