Lowering oil temps...
I recently went to an lsx block and I just can't keep the oil temps down.. I kept the stock Z51 oil cooler on my car and I think it does nothing.. I believe the air cavitates around it and makes matters worse considering the temps go up on the highway and lower in the city..
The car runs around in the city @ 230.. hwy at 240-245.. after one pull 255-260.. Is there a larger oil cooler bolt on kit for the C6 that is available, or does anybody have advise on what cooler to buy and where to run it..

Some guys go with the Z06 external oil cooler as did I but I'm adding an e-force and a larger heat exchanger so I'm not sure if Ill have room for the Z cooler. I think I payed $400 NIB. for it. There may be cheaper aftermarket options out there tho.

You can use the LS7 oil cooler. Itll bolt in, if your shroud isnt cut up from the blower. Its about 3x the size.
I also say, what headers, and whats coolant temp because you can run the Z07/Zr1 water-oil cooler, but it wont fit with every header, and you need a GOOD radiator, because it sheds oil temp through coolant temp.
Your next option would be a custom setup in the fog light area.

I'm in the middle of an LSX build as well. I don't want any of those issues so I chunked my stock Z06 Dry Sump stuff and bought an ARE Dry Sump Setup and a bigger oil cooler mounted in the stock location and a Afco heat exchanger as well. Call Taylor at Dallas Performance and he will get you lined out

I am not a believer in the dewits considering many local people see the exact same coolant temps that I do with a stock radiator..
Louis, I run the sw 1 7/8 Z06 headers.. So the Z06 cooler should be an option.. I think I will stuff one in there and see if it helps... and I think I am going to bypass the oil cooler in the radiator, to me it seems more like a heat exchanger more than a cooler.. We'll see where this gets me..

About the radiator,I tried both and there were no difference. Now for the OP, I eliminated the oil from running through the radiator and added an independent oil cooler with a termostat switch which controll the fan made on the oil cooler, its about 12" x 8" and 1" thick, it work fine, I also did the same for my transmission with the oil cooler located at the rear under the left rear compartment. My front is located at the left front above my fog light and a small cutout behind my grille on the left side.

Good thread.
The big issue here is that all of the forced induction guys need a LOT of cool air, coming into the front radiator inlet.
With blowers and turbos, the front mount intercooler adds a lot of complexity. There is only so much air still flowing through that opening.
By moving the oil cooler to the fog light area, itll free up cool air to cool the Radiator, AC and intercooler. The oil will take new air, from another spot, not adding any load to the cooling that the front inlet already has.

The ZR1 cooler is inadequate unless you have a big radiator, and keep coolant temps below 200. At 260 water temps, oil temp is 280+
The camaro cooler is smaller, and the coolant block is rotated 90* from the ZR1. I would not use the Camaro cooler unless it was your only option.
With EITHER of those coolers, you will need to tap back into the radiator, or coolant return hose from the top of the radiator. It pulls coolant from the side of the block, and returns it to the left radiator tank.
Trini, what he is saying, is that the BTUs must come from somewhere- Its heat energy, it doesnt disappear, but is simply removed from the oil, and its returned to the water, thus adding temp to the water/coolant system.
we run the stock cooler on the ZR1 hill climb car, and with out the big radiator ( not a dewitts, or even our current supercool style, but a race inspired 2 row with custom fin/inch like we use in the ALMS car, it was not enough oil cooler.

on the Same start to stop run. my car hit 215-220* oil temp VS jays 260*. I still have stock radiator with stock Z51 cooling stuff, but jay has an LSX vs my ls3... is the LSX generating that much more heat that oil is 40* higher after literealy the exact same drive/pull?
im looking at LSX blocks and im just trying to pre-emptively figure out what will need to be done to keep it cooler

Ive not ever seen an issue, due to LSx blocks and temperature. I think sam did a good job on your shroud and the cooling/front mount portion. Thats a big portion of it. Relying on the fan to do the work, and you will have issues.
Also, if the engine is brand new, seeing those temps, I would be curious to know what oil was in it and what pressure was, as well as main and rod bearing clearance. If the clearances are wrong, oil is inadequate, or tuneup is off ( unlikely) that could cause the issue too.
Id cut the oil filter apart on the high temp setup and send an oil sample off.
Also, what are the power differences?
Medics car ran hot too, but that wasnt due to the blower. The shroud was effectively ineffective, which is just the nature of the kit. It takes some due diligence to build the proper shroud.
