what is doing everyone doing for oil cooler? currently not running one

 

I was wondering the same thing. Turbos add a ton of heat to the oil.

 

What is temp pushing to? also need to take ambient temp in consideration.

 

The first duramax block was redesigned due to low oil temps. Lube galleries in block and heads where decreased .065 smaller. If you gm super diesel builders look up some of this data you can add miles to the brute and save $ on mods.

 

Look at my build i run a huge cooler out back on my 02

My 2010 i use factory cooler

Thicker oil is a must as will help with temps

 

Anyone have a comparison
Oil temp with a turbo and with out.

 

I use a large Derale cooler up front and most importantly for a street car, a thermostat from Improved Racing to make sure the oil gets up to 180 degrees. The tstat block adapter is a bit pricey but imo if a factory truck has an oil cooler then a turbo truck absolutely needs one. If you've ever driven a C5 Z06 with even a stock motor (they did not come with an oil cooler) and beaten on it you'll see the oil temps rise to the mid 200s real real quick.

 

just ordered a derale 15800 with fan so i can mount undeneath truck

 

Yea, I added one to mine when I first got my turbo stuff going because it was so hot. It maxed out the gauge after a few minutes of just cruising around the block. I use an autometer digital gauge right at the filter area, -8an lines to a 5x11x1.5ish b&m plate cooler in front of the radiator in the corner. 160 degree engine thermostat.

With turbo:
W/o cooler, city - 250+
w/o cooler, hwy - ???
w/ cooler, city - 185
w/ cooler, hwy - 215

Without turbo (stock 195 tstat):
W/o cooler, city - ???
w/o cooler, hwy - ???
w/ cooler, city - 185
w/ cooler, hwy - 185
