Blue Grass (Eastern IA) | Going to take the old open station 4430 to a farm pull Sat. I will pull in the 11,500# class. Which screw do I turn to get some more ponies? How much can I safely turn it up? It has an inline bosch pump running about 130 hp now.
Thanks |

N/E Iowa | Half a turn on the screw will surprise you. |

Wallis, TX | In my experience in a more or less stock pull a few ponies won't matter all that much. Tire pressure, hitch height and weight balance are far more important than a couple of extra hp. Now if you're talking turning it past 200 and running 6 or 8 mph then different story. |

Central Minnesota | very back of the pump, next to your oil filter, you'll have a small plate... 4 bolts on it... Takes a 10mm wrench... Take those bolts out.. Inside there you will see a long "screw" with a jam nut on it... loosen that nut, and turn your screw IN.... 1 turn sure won't hurt... Depends on the pump, but i'm sure 1 turn on that pump, which probably has 11mm plungers is probably only about 30-45cc's of fuel... But not exactly sure... You could very easily go more. But careful... Your injectors will be the limiting factor on how much fuel you can safely go before you wreck your pump... Just remember that IN is more OUT is less when it comes to fuel... |

| old rule of thumd is 1 turn=20hp but that is not correct. 1 turn can give 10hp or 60hp in my experince once you ngo over 200hp you will lose the turbo when they came from factore minimal was 120? but they could go up to the 200 before factory would reset |

Northeast Louisiana | We have a 4430 still going, once in shop back in early 90's. I had John Deere to put it on dyno, it pulled smooth 200, they turned it down some, Still running now. The thing is, the pump has never been turned up. Still had factory seal on it when on dyno and had tractor since brand new. Engine has been overhauled once and has around 15,000 plus hours on it now. Go figure.
Plus... will it pull like a 4960 or 8330? Heck no. But it will walk with its own weight.

Lewisburg, PA | Little fire and smoke out the turbo will not kill it for a couple pulls

western Pa | Whatever you do leave 3 threads showing out of jam nut. If your real ambitious get a long screwdriver and back rpm screw on pump back to get a few more rpm's. Don't get carried away there. Don't worry about over fueling it the rack in pump and the aneroid will stop that. |

Blue Grass (Eastern IA) | Going to pull at Walcott, IA
Thanks for the tips. I figure I need around 200 hp to run with the 1066's that will be there. |

Wisconsin | Are you positive about that? Worked for some fella's that thought useing the 4440 in the local pull would be okay and fun. Dealer was dynoing it and blew up turbo at around 300hp. Then later in the pull with new turbo pulling in B-2 boss slapped it back to 1 where tranny went bang took home second place where it broke. Seam's common on those Deere's to flip drawbar for higher pull point only to snap the bar or worse pull out the anchor point underneath. The partner's I work for now also set up their IH 966 once in the earlier day's it did okay also taking second but when the boss with the bad back drove and his Bil. got to move all the weight's on and off or around one tractorpull event was enough. |

N/E Iowa | We had a stock 140hp 1980 4440, that with 1 turn in gave it 202 on the dyno. I was told it was useless due to there is no intercooler on the 4440? |

| Panotiller that is just plain awesome to see the old girl running hard. |

NE Iowa | When's the Viroqua pull, and how heavy of weight classes do they run up to? How would a 4440 and 4455 both with around 275 horse compete with everything else that's there? Just curious if it'd be worth a trip across the river |

NE Iowa | If you'd put a pyro gauge on it I see nothing wrong with a 200 horse 4440. I'm pretty sure you'd be alright if you keep an eye on exhaust temp and coolant temp. |

south central nebraska | In my experience, the intercooler really didn't make much difference. Seen one put on a 4555, because of a low horsepower complaint, didn't make any difference in hp and still had to turn up the smokescrew. Also know of 4630's and 4840's with them taken off because of they needed replaced and the customer did not want to spend that kind of money to replace. |

sw MN | Running @ 300 hp it should have blown up. Common sense says 2 x stock hp will blow something up. 200 hp would be ok |
|
| |
|
| fuel screw, timming, did i say reset the timming, 3100 RPM's should be close to 300 hp, pull in D 1&2 if it is a quad range.. |
|
| |
|
| one turn won't even make you competitive around here. I'd go 3 or 4. BTDT on a 4440
