Malibu,
I have been building my 2000 K3500 4x4 dually, quad cab, auto tranny, 200,000K to pull around 26K. I purchased the truck 2 months ago at a cheasy type lot. I am pulling a 2006 haulmark 30' gooseneck 3 axle that loaded is grossing around 23K over the continental divide in MT. The first load almost killed it, 230 degrees, 10 MPH and black smoke at the top. After the first near death for the truck experience I have tore into it. Where to start LOL.....
From SS diesel supply new Marine injectors, lift pump, PMD relocator, oil pressure switch, 4 in. stainless exhaust, high volume water pump, 180 degree thermostats, their best fan clutch, boost gauge, cold air.
From auto parts warehouse bosch glow plugs, glow plug relay, boost solenoid, turbo charger (should have went with a better one but didn't
two things i'd know, will run it for a while) new steering box, a arms, tie rod ends, billstien shocks, pads and calipers.
I haven't had another big load over the pass yet but with a light load (small trailer) it didn't even shift down on cruse from 65 mph. Boost peaks at about 12-13, pulling the hill 6-8, flat ground about 3. Temp never went above 190 but it is colder here now to, no black smoke. I am going to build a manual wastegate controller from instructions here and experiment for more power. Before summer I intend a new radiator, oil cooler and lines and water wetter. Mileage has went from (highway empty) 10 to 15 mpg.
Can anyone tell me if I had a larger cross over exhaust pipe made would it help or should I stay stock diameter? and how much tension spring should I use for the wastegate controller?
I am hoping for a couple years until I can afford a newer 3500 for the company.
