Anyone find a better way of cooling the oil by way of removing stock oil cooler and installing a more traditional oil cooler?? And if so did it help??
im currently modded to 700RWHP and I made 3 hard pulls from a dig getting used to launching this bad boy. I was out on a desolate road and by the 3rd run the oil temp was hotter than hell!! Didn't go into limp mode or anything like that but seems to me like the current setup does a better job of the oil heating the water than the water cooling the oil.
Anyone????
There is a new thermostatically controlled adapter that was recently released. Use that in conjunction with a stand alone air/oil cooler and you should be fine. Just need to figure out where to place the core, which isn't easy. Good luck!

The only solution we've found that REALLY works (not just for a few pulls, but at full power for an extended period of time) is to move the intercooler radiators out under the headlights which improves airflow to both the engine radiator and intercooler radiators, and putting oil coolers behind those intercooler radiators. It would be great if there was a way to give the oil coolers fresh air as well, but given the higher fluid temperatures, there's still enough delta-T in the air coming off the back of the intercooler heat exchangers to effectively cool the oil.
Even then, if you want to run full track sessions in 100°+ summer weather, the radiator needs to be much larger. Our Stage II cooling system actually breaks the radiator up into two pieces in a "V" arrangement to get as much airflow as possible.
"Conventional" oil coolers like you're talking about are a step in the right direction, but just aren't enough to provide significant improvement.
Yeah, it's a problem the aftermarket shouldn't have to solve for GM, but we solved it anyway.
Here's the Stage I Cooling System we sell, with links to the development thread and upgrades for engine oil coolers, Stage II radiators, and transmission cooler upgrade for the A8 cars.

Highway runs? 1/2 mile stuff? or Road course work?
Really depends on what you are doing with the car as to what parts might be NEEDED to solve the issue on the car.
Also, manual or automatic?
Is it just the oil that is getting warm? Of course on the dash that and engine water temp are the only ones you are really going to see, the blower temp is going to require HP Tuners or similar to read those temps.

What is hotter than hell? Maybe what you think is hot and what is actually hot are two different things. I ran my stock car in low to mid 90s temps for 20 minutes at a time making quite a few WOT pulls per lap and never saw the oil go higher than mid 270s. That is far from being over temp. Starting at an oil temp of 150 degrees 3 hard pulls wouldn't gotten the oil near that level. Hard to see how 45 seconds of hard pulling with a 700 RWHP engine can get the oil hotter than 20 minutes of doing the same with a stock engine.

Hotter than Hell to me is defined as the temp needle being just below the top white tick, I'll call it 300degrees. And as far as starting with an oil temp of 150degrees I never saw that. I cruised to the location and Oil temp was 200-205degrees (that's normal to me) 220-250degrees max is also ok but anymore than that and I'm concerned.
I have a wheel setup for drag racing in the garage but I also am looking into Open Road racing and for that I'd like to keep full Aero installed. So basically I was out testing my rig to see what it can take and where it would have weaknesses. So with full aero I went out to make full throttle runs on a 2-1/2 to 3 mile desolate stretch of road that is in excellent condition. I wanted to see my max mph with full aero before I ran out of road and have to slow down. I broke 190 and stayed on it a few more seconds and let off, I immediately slowed turned around pointed at opposite direction glanced at gauges and let it rip. I made it up to 170 and totally knew I wasn't gonna be anywhere close to previous run and I also knew that the SC was gonna get hot also. I slowed down to a 50mph cruise looked at gauge and saw the Oil temp gauge at the top white tick so I pulled over when gauge oil cooled down to middle of gauge. I pulled over and opened hood and was smacked by the unmistakable smell of Hot engine oil. I lit a smoke and let her cool off before the drive home.
The system by G-Speed is exactly what this car would need in the application that I am still pondering and not sure if I want to commit to. But I am still on the fence on that because I personally feel that in that particular application Turbo's would be better as you wouldnt have to worry about keeping supercharger cool for extended periods of time.
I know I asked about Oil cooler but after much thought Oil temp wasn't going to be my only problem. I know IAT's were high so goes the rat killing. One at a time! Thanks everyone for your input as always this forum is awesome!!
Suggestion: When you are making your high speed runs, put the dash display in touring mode and select performance. You will see an actual digital readout of the important engine parameters instead of the analog gauges being "at the top of white tick."

Good suggestion thanks! I hadn't thought of that since I never have it in touring and I have everything set up to link to mode so next week I'll try that once I remove all aero and see how stabil the car feels at high speed. Forums are good for info but something's you just have to find out yourself.
Hi Tom does this fit c7z A8? Would you still recommend it for warm weather at Average of 96F for track use?
I am interested in a single best solution with budgetary limitations ..
For 96F ambient track use in A8 Z06 this will not do it. Look for GSpeed solution which uses Dewitt coolers. They have a very detailed thread on this topic. Cooling A8 Z06 at the track is more complex than you think.
Tom,
I have a few questions.
Can this oil cooler be used on a '16 C7Z A8?
Can this oil cooler be used in conjuction with the "improved racing oil cooler thermostat"?
Is your annual 15% OFF sale going on at this time?
(I am wanting to get the oil cooler kit and the gen2 Rad)
Thanks, Andy
