9500 turbo farmstock class
|
Last year a new class came about. This is a 8mph 3,000rpm 9500lb turbo "farmstock" class. However it's for tractors with a production year 1972 and prior. This is a sanctioned points class with a cubic inch limit of 430ci unless that tractor was equipped with a block of greater ci from the factory. You must retain the factory part number block, trans, and rear end. You may add a turbo to a factory N/A tractor and may use any oem head of the same manufacturer as the tractor. Any tractor equipped with a rotary injection must stay a rotary pump tractor but you may do any modifications to that pump. No 3lm turbos. You must use a to4 or s200 series turbo. I was wondering if I was to use a 4320 or 4020 with a .450 pump what kind of horsepower potential is there? What are my options for adding power? What head would one use? Thanks in advance |

Just a turbo clarification, it is a 2.30 inlet and 2.50 outlet max to allow other brands such as Garrett and Holset to be utilized as well. As long as the turbo meets those dimensions it is legal. Glad to see you considering joining us. With a .450 pump, I dont see why 350 wouldn’t be obtainable on the low end. The S257sxe is a really good turbo to match these smaller cube tractors. Best of luck and any questions feel free to shoot me a message or call me. |

Make sure you're using a steel flywheel. Hopefully, the class rules require it. It's not pretty when the stock cast iron ones fly apart. |

Steel flywheels not required. Its 3,000 rpm checked every hook as well as randomly if theres any question. Cast disintigrates at 3500rpm, while we are not opposed to people running them they are not required. Some of the tractors that run with us are still used on the farm and truly farm tractors. Its an 8mph entry level class, not requiring a steel flywheel for that with a 3,000 rpm limit |

As has been explained NUMEROUS times, it isn't the ram's.
It is the heating cycles. Steel flywheels or leave the stuff in the shed. |

And like I said some of these tractors are still truly farm tractors and used as such. Mandating that would eliminate over half the class. And I understand the heating cycles as well…guys aint slipping the clutch to run road gear at 8mph |

They may not be slipping the clutch right now to run road gear at 8mph, but they will be in the future. What kind of insurance do you have? |

The way the class is we fall under the insurance of whatever event we run at. We do not run our own class insurance. Most of the places we run, we are the only class with an enforced rpm limit. Furthermore, it will not get to the point of running road gear in an 8mph class that I can assure you. I will post a copy of all rules here |

The little organization I pull with is the same except theres 5mph farm classes for the off the farm tractors. Problem is though, most try the open 8mph classes with their farm tractors and go back and forth, so the farms are getting hotter, the true opens for the most part has safety equipment but the safety equipment needs to be mandatory and enforced to keep farm tractors out because like you have said, its hard for farmer that actually use their tractors on the farm to pay $2k+ for a sfi clutch. Most likely 8mph is all the insurance will cover without mandatory safety equipment. What you need is a tach box on the sled and plug everyone to it going down the track. |

The material is actually flowing under tension caused by centrifugal force and opening up voids that eventually lead to cracks. Failure is a factor of load (RPM) and cycles. There is no magic number because each foundry pour is different and each loading and cycle time is different. My Grandpa used to say, "Never turn you back on a Bull, a Handyman Jack, or a Cast Iron Flywheel". He lived till he was 102. |
