Engine & Tranny problems 2

[Gregory OConnor]

Leroy, I dont know that the HP will read less with the fan on. I
think it is more a loss of 40hp with the fan because it is directed
to the effort of running the fan at the expense of the ground drive.

When I added a jake to a truck they refered to the holding power as
HorsePower of hold???? I wonder if your computer has a way to read
the HP backpressure hold with and without the Allison Retarder? I am
curious if You and DonB have the same HP hold. I think Don has an
different Allison and a larger external retarder (like Curts 87)?????

I wait for the computer to turn on the fan in my hydrolic driven PT .
In my Dump truck Cummins N14 the fan is on an air clutch with a belt,
Like the FC's. I turn it on via a 'fan on switch' prior to a hill
(boxsprings Riverside 60/215)when I can back off of the RPM's. I
hate clutching up the fan at high rpms.

Talladega has nothing on the crowd in Fontana. When I rolled in with
my lodge a spectator said " We was gonna bring ours to stay'n but
it'sa doublewide."

The program gave me the data which I really wanted to see, primarily
temperatures. The numbers received completely support my previous
test results over the past 8 months.
> If the engine is putting out 475HP instead of 500HP and I can
change the program I'll sure do that. Otherwise, I'll not be
concerned about 25hp. If I can change the parameters, I would only
expect to see slightly lower Power Analysis numbers distributed the
same across the board in the three fan configurations.

posted from my trip? If the program is reading the DDECII properly
and I believe it is, I find it very interesting that HP is not
decreased by 10%(50hp or 47.5hp as the case may be) when the
hydraulic fan is on.

exist in the profiles, and both HP and torque are calculated based on
the engine profile - It sounds like you are using the 500.
