LS Oil Cooling?

[badazz81z28]

I’m going to install an oil cooler on my LS7. Question being how are you guys doing it? Are you using an OEM connection and hard lines or are you using something like improved racing and hoses? I guess some of the LS engines had done monstrosity on the oil filter area.

I was able to use the stock GM hoses and just make a set of brackets for the cooler to mount in front of the radiator, the hose length worked good. A friends car we used AN lines but had oil pressure problems that ended up being caused by the billet aluminum block adapter, the hard 90 drilled passage caused flow problems, porting it on the inside corner fixed that but only after eating a set of bearings. So IMO... try the GM stuff, cheap and it works, they are good quality crimped ends too.

Are you referring to the improved racing adapter? Are you using a temp regulator?

No, actually it was the Limgenfelter block to AN line adapter that caused the problem, no thermostat. I run the 06-09? Z06 oil cooler and just use a cover on it for spring/fall street driving otherwise I always have cold oil.

Interesting...I guess factory vettes didn’t have cool oil issues?

Does it matter if the cooler is a oil to water? I would think that temp would always be constant? Versus the outside air to oil cooler?

I run an improved racing thermostat with an oil cooler in my radiator. Works great. I think a thermostat would be optimum for an air cooler.

i was going to use a standard cooler (air to oil), but decided to just get the C&R Racing radiator. Just making sure if the type changes the opinion on T-stats.

I run the thermostat with my C&R radiator. Goal is to keep the oil warm enough to boil off any moisture so I run the higher temperature one.

I used the Mocal AN adapter and thermostat when I was using a wet-sump, assume the same would work for a dry-sump. Worked fine, but you have to be careful of header clearance as that is where the pipes are heading down. Had to modify my first set of headers (custom tri-y) when I added this.

I run the improved racing adapter with the integrated stat on my wet sump LS3 and it works well for me. For a dry sump motor you may want to consider using a local AN thermostat though, and plumbing it on the low pressure feed to the oil pump

Im about to hit the button on the Improved Racing version. I didn't know about Mocal...I like how it has a port for my oil pressure sensor which was a concern of mine....I have everything but the adapter. Does anyone have pics?
