C KS | have a 430hp/470hp Detroit in a 9200 IH the (470 only works on cruise). Any good reason why I shouldn't have it set to 470hp constant? Like to compensate a little for a 10 speed going up hills. |

Fairbury, NE (Southeast) | nope go for it. Won't be as noticeable as you think, but will help some. What are you running for rear ratio? We have a 4.10 and a 3.70 set at 430. The 4.10 set at 470 does a bit better. |

south Texas , York Rife Freemason | It might take a setting above 470 , i would not be worried at 470 .
The later series 60"s are 515 h.p.
I dont have access to the software to set the hard h.p. settings , but the fellow that sets it up will know . |

Wheatley, Arkansas | And IMO the later 60 series at 515 hp and 14 liter are dogs compared to the 12.7's @ 500 hp on both power and fuel economy. All the 14L's I've been around, ours included, sound like a jet engine idling. |

NE Colorado | My 12.7 at 500 is the best truck engine I have run. No, it doesn't have the low end torque of the big Cats but it has plenty and routinely runs a mile per gallon better than the Cats. |

| When you got the computer on just get it set at 500. We run a 9200 with 4.56 gears and 18 speed pulling 140000 lbs in Ontario and it will flatout pull. It will run along with our 600 hp volvos that run 3.90 with 18 speeds. My quess would be that you could run a 12.7 out to 515 with no issues. |

I dont remember when the sn # break was , but most of the 14 L"s are egr , where alot of the 12.7"s are not egr .
Egr did not help the engine -imo .
I think the size was increased to compensate for the EGR .
Thank the govt. |

Cleveland, MS. Own small farm near Booneville, MS | I ran one of those set ups for awhile. IMO there is no difference in the hp from cruise to foot throttle. While Detroit claims a difference I strongly believe it is just a sales gimmick. I tried hard to find a situation where I could feel/see the hp difference. It pulled the same hills with the same load in the same way - foot throttle or cruise made no difference. When you get the computer hooked up just have the tech turn it to the max hp available for your engine and make that hp available all the time. Then, and only then, you will be able to tell a difference. Mileage may even increase due to the engine not having to work as hard and you won't have to downshift as much. Having to downshift on a hill is a real "fuel consumer." |

nwks | just something to think about going to 500 hp will shorten engine life 50,000 miles i have two that are enhanced 425 and two that are 435/500 and yes the power is nice but they may not last quite as long |

nwks | the way i understand it, you have 435 at 1800 and the 470 at 21 or 2200 i think that all diff is when on the cruise the gov is raised and im sure if i dont understand this im sure i will be told on here how it is
but i dont know who runs there trucks this fast
i tell my help that 1300 rpm is where to shift at make the torque pull the load
so if you only get the added hp between 1800 and 2100...who runs 1800+ on the cruise? so with that maybe someone on here can explain this cause what i stated earlier dont make any sence now.

60 series Detroit question
