466 HP?
|
HOT
|
We put together a IH466 in a 1066 and was wondering what kind of HP we should see. Piston valve reliefs .250, suites 3000rpm cam, cleaned up head port slag and smoothed, Shied 13mm 3000rpm mod 100 450cc, .120 lines, single feed 5x22 inj, 2.75 x 3 hx50 turbo, gonna be running water also. We can push 60-65 lbs of boost. Havent had a chance to hook to a sled yet , but can't pull the tractor down in H4 with the ta back standing on the brakes till they smoke. We can pull about a foot of flame out of the exaust elbow,32 degrees of flywheel timing. Any idea of what HP we should be putting out, and also how were gonna do hooked to a sled in a enhanced farm class at 9 and 11k classes. 3,3.25,3.5 and 4 gears in tractor, 20.8 tires.
Thanks |

There are so many variables to this puzzle, I'll guess 800 to 900. If you have the opportunity, go to the Dyno, it is the best investment you can make and you can tune it in and focus on driving. As for how you will do, all I can say is good luck and enjoy yourself. |

What is holding you back a little is the 2.75 charger. |

Re: 466 HP?

hold on a minute
|
with the rotary pump and them injectors im guessing more like 550-600 hp |

We went with that charger because we didnt think we'd be able to turn a 3x3. Whats wrong with the 5x22 injectors? Would something else work better? Why the big diff in HP estimates?
Thanks |

It's just so hard to tell. I respect everyone's opinion. I think you could spin a 3x3. They do it in Missouri with a 414, 4x28's,and a 15mm big nut rotary pump at about the same cc's. It is a 3000rpm class. What do you have for a fuel supply pump? |

Mechanical driven off of the crank. Regulated to 80psi at the inj pump head, plenty of flow-all fuel supply lines are 1/2 lines.
What kind of HP does it take to run road gear in a 9K class? |

I'm not sure, but if you keep the fuel to it and with that charger, you should be fine |

Your gonna have to hook it yourself a few times to answer some of your questions. 600 hp will put you in road gear sometime,easy starting speed sled, loose hole your good. Sticky biting track goofball sled operator you'll kill before you get 100 ft. Might want to get some water on it or put that fire down a little or your first one might be expensive. Reread see your adding water my bad. Edited 1 time(s). Last edit at 04/25/2012 01:19PM by easton stealth. |

Might need dual feed injectors as well |

Re: 466 HP?

Saw that exact setup on Dyno, wouldn't spin turbo. Put on 2.6 made 550. |

We ran a similar set up with out water on two of our tractors and we ran RAT 20.8 x38 cuts and we ran direct on a clay track no problem
About 24 mph we always thought about 800-850 hp |
|
Re: 466 HP?

I seriously doubt you would have over 600 hp with a 13mm model 100 pump, too bad you couldn't run a p-pump then you could make your 8-900 hp like some of these guys are talkin |
|
Re: 466 HP?
|
been there
|
even with a p pump i dont think you would get to that 800-900 hp range with that 2.75 charger throw a 3x3 garrett gt 42 on there and then you would, i had a 466 ih with a p pump and a hx55 2.75x3 and had 730 hp then put on a gt42 3x3 and went to 900 hp,so my guess is with the rotary pump and small windmill you prolly gunna b 500 or so. |

How does 450cc in a mod 100 compare to say a 450cc A or P pump? I know usually an A or P will put out more than that. The mod 100 does have a fast cam in it also. |
|
Re: 466 HP?
|
I'd like to see the 450CC 13MM model 100 myself. That's getting into 15MM delivery. |
|
Re: 466 HP?
|
It mite deliver 450cc at 2000 rpm but I'm pretty sure its more like 300cc @ 3000 rpm, the fuel delivery is so erratic on the ambacs and the more rpms you run the worse they get. |

Re: 466 HP?

dynoed it
|
466 3000 RPM P Pump 3x3.25 s400 with 2.75 bushing and lots a water made 1100hp on dyno. saw it happen myself. i know some will say it aint true but i know the guy that did it. saw it myself. |

I think it has alot to do with your cylinder head. You can put the biggest turbo on there, but if your head isn't opened up to let it flow, it won't run. Take a smaller turbo with the right head work done make more hp than you think. Some of these guys on here more than likely had different head work done...by different shops..makes those hp numbers fluctuate. This is just what I think. Tell me I'm wrong? IDK |

Re: 466 HP?

broken dyno
|
Let me be the first to say yea wright aint no way. I can see if it was open rpm but 1100 hp at 3000 rpm please. If your trying to get a response you have got it. A 466 at 3000rpm would not even keep that large of charger lite. Come to remember I saw the pot of gold at the end of the rainbow the other day and then I woke up!!!!!!! Are you still dreaming?

How much would it help me to change the mod 100 to open rpm, how much HP increase would I see with our setup? |
|
Re: 466 HP?
|
Like I said earlier, Dyno 550 hp. You need to check your rulebook and see what the rules are and what class your going to run. If you are trying open Rpm with bigger charger your wasting time with mod 100 pump. |

U have a 3000rpm camshaft and ur engine is setup for 3000rpm so putting the heavier governor spring in is not gonna help that much unless everyone else are lettin the rpms rip too, if so u should have when with an open rpm setup. |

i can build you a 13 mm model 100 that will flow 470 and stay alive. have 3 on tractors now. |

as one post above says,,as rpm increases,fuel delivery will decrease on the model 100. you just dont have enough timefor the charge ports to refill the plunger bore fast enough..remember,,,,1 plunger,,,,6 cylinders,most shops draw the cc of fuel at 750 to 1000 rpms on the test bench because of fear for plunger seizure . i have ran them up to 2000 rpm and delivery will derease.even with 100 psi charge pressure,and an extra charge port in the head,, so answer is an a or p pump will show power gains for sure |

Re: 466 HP?

big pump

I've heard you build some good solid pumps. What size turbo do you recommend with your pumps and what are you seeing in gear selection in the 11k classes. Any HP guesses with your setups |

I ran pretty much the exact same setup, for a couple yrs until we bought our p pump i would suggest bumping the timing on up to about 38 degrees, my suits setup made the most power with about 36 to 38 degrees of timing. U should have no problem running road gear as long as u have a good clutch, in a 11000 lb class, if u can run a 3x3 i would suggest a good gt42 charger with the billet 6 blade batmo intake wheel and prolly a 98 or 101 exhaust housing spend the money and let they do the intake cover enhancement and the exhaust wheel balancing ehancement its all worth it, that charger will cost 2500 to 3000 but is worth every penning and will push about 90 to 95 pounds of boost. Just speaking from my own experience, good luck have fun. |

I dynoed my tractor this winter. I believe it's possible to make those numbers. I have a 466 3000 rpm p pump 3x3.5 s400. Turned that big turbo just fine. It can be done. Just takes a lot of work. |

1100HP on a 3000rpm 466 without an intercooler would be very tough, with an IC I would say it would not be hard at all. If you get 1100hp with the above setup I am going to guess you will be the tractor to beat wherever you go based on power. Of course I have seen the same engine dyno back to back on two diffrent major shops dynos and there was 150hp diffrence so a number is just that, all you can really use a dyno for is seeing if what you changed made it better or worse. |

Re: 466 HP?
|
just saying
|
Most super farms, 640 ci, open rpm, 3x3 charger, p-pump, dual - triple feed inj., same if not better head work would not make much more than 1300hp add a cooler and sure it would go up. Truthfully hps don't mean much but torque is the true question and answer. |
