What bhp do these have and what torque?

Good on fuel?

[buckeyeguy2000]

From the factory, they were rated at 160hp (I think) and 400 ft.lbs of torque. This one has the fuel plate turned up about 1/4 and the timing is slightly advanced, so I'm guessing that it's putting out a little more of both.

and

94-95 auto 160hp

95-95 man 175hp

96-98 auto 180hp

96-98 man 215hp

most would easily get over 20mpg. currently in my setup, I am at about 22-23 average, with a top of 25.5 with a 600lb engine in the bed. im gonna bump my timing up to about 15.5 and how much it helps too

@tpvalley

advancing your timing forward (within reason) makes your EGTs go down, cylinder pressure go up, black smoke at peak torque go up, and fuel mileage go up

[cowboyts6]

from the factory it should really put out 180hp and 400 ft-lbs of torque because that is what mine does say on it on a 92 cummins

My diesel has a dynamic advance adjuster,

fuel pressure advances timing, is this the case on yours or did u just turn the pump?

What effects did advance have apart from more knock?
