idle once warm.. is between lly and lbz.. exhaust note.. couldnt tell you
sounds like a lbz/lly at idle little more turbo whistle
LBZ: just split a piston at 250fwhp

Definitely get and oil temp gauge in it! Mine is running 180-220 degrees averaging just over 190degrees and I am 6K lbs 2wd, could only imagine what your actually seeing for oil temps. Your sound is probably not far off stock because of all the stock parts you are running. It takes big plumbing, turbo, cam, etc. to really change the tone of the motor.
Adam, from what I have found.
Sustained higher RPM but low egt is harder on the oil than lower rpm(2200 and below) and higher EGT. I see you have gears and cruise at 2400rpm+. I wouldnt be surprised if you see 250*+ oil temps with a moderate load on the truck. I saw 274* in my LB7 towing 10,000 up a 6* grade for 8 miles at 55mph in 4th gear.
Oil temp gauges really opened my eyes in these trucks with temps. I value a oil temp gauge more than EGT. We only realize our trucks get hot when the engine fan comes on, well, what are the oil temps to drive the coolant temps up? You dont know untill you put a gauge in the truck, and I can promise you, your oil temps will always be higher than coolant temps while towing.

X2, exactly right! I will be upgrading my oil cooling because I love higher rpms and oil temp climbs quick when you jump the rpms up for longer periods of time.
on this trip form ohio to wisconsin with a heavy load with by sail area plsu 20mph head winds.. im sure its high.. actually could watch the oil pressure drop when climbing a grade.. avg OP was 45psi are 2200-2300 with this load. caught it down to 38-40 on a grade same rpms full throttle.. backed off and OP came back up.. giving the charaterisitic that it beign heat related..
i rarely see ECT temps above 200*... fan will come completely on at 200* (hyd 2886 clutch.(more repsonsive then the stock lb7 i had). also keep in mind i dont have a bumper siting in front of the radiators like the regular trucks do.. means more airflow)
im thinking putting one of these on for my setup with a thermostatic bypass i dont think i need the 601

I know with my oil cooler, with oil temps at 165*-180*, at 1800rpm im at 62psi. GM spec is 42psi @ 1800, so im well above that.
useing the dash guage?
i got mine tapped into #3 main the ecm sensor is #4 main..
i have an autometer since i havent gotten a 6.5 oil pressure switch to route to my dash guage... yet
I see 42 PSI at 1650 RPM, but my motor was built really lose (insert mom joke here). What oil are you running?
Superdiesel spec'ed out a really nice setup in his thread, I have been running his setup and have had 0 issues towing with triple oil cooled turbos

15w40 delo conventional.. its probably looser then stock.. new bearings but didnt turn the crank.. journals where all in spec..
i can swap my ect to oil easily if the t-tape doesnt keep then sensor from grounding
im head to columbus ohio tomorrow with a generator (~5500lb)

i will run this for 10k then proably swap to syn..
how much does it cost per 10qts?
i run 10,000 miles every 5-6 weeks,
35.00 for delo 1300 from walmart plus a 10.00 B1441 oil filter
45.00 for an oil change.
that cost me ~4.5cpm
only thing i would be really sold on is if i could extend my service interval by min double..
i did that with my fuel filters... spent 100.00 in setup and it will last 60-75,000 miles and cost 37.00 in filters( 2 micron fuel and a f/w sep) per change vs the oem every 10-15k
cost to service life is something i have to take into effect..
with the oil cooler i want the cooler down streem of the filter... hot oil filters quicker better and smoother then cold oil. i dont think i can get that on a sandwich plate adapter..

Good to hear your back up and running Adam.
While on the topic of oil temps, what extra cooler kits are out there for extreme winter conditions? I want to go with something that won't make my oil too cold when it is -30 out-especially cold starts that might take longer for the oil to warm up.

Thanks.
I would like to see the SD set-up. Wouldn't buy an O-ring from that Killerbee clown.
I went to SD's website and it looks like it's just one big site full of ad's and nothing that shows his products. Gonna have to do a search on here I guess and see what I can find.
this is what sledhead used modified by supper diesel

(Opening starts at 160 degrees, fully open at 180 degrees)
my consern is goign too big and oil never gets warm enough and im lifting the pressure relief valve all the time in cold weather or dumping hot/cold oil in a cyclic fashion..which IMO is worse then just hot oil
