I'm not sure if this video has been posted before of a ZR1 at COTA....the driver seems to have a lot of vids of cars he drives but I have no idea who is other than he drives a lot of cool cars on the track.
In his written comments he claims the oil temp went to 271 degrees by the second lap. He states the ambient temps were hot, but I'm a little surprised that the oil temps raised that high in such a short period. I'm only reporting what he wrote, does anybody else have any information on this track run or the driver?
I'm hoping this is a misprint because two laps with this high of an oil temp is a little concerning.
1. Car has 15W-50 oil in it
2. Car is on Hoosier R7s
3. NO GT3 smashes lap times at COTA, they are painfully slow compared to what we’re playing with.
4. I cut the video because I backed out and let my two buddies regap me so I could do a hot lap. They didn’t know it was me in the car and I wasn’t about to stuff them in the brake zones.
5. COTA Speaking, you need a large footprint, lots of power and downforce, the GT3 doesn’t have lots of power and it has a small footprint. Some of my GT3 friends run 295s up front... not sure what that setup will do.
Looks like the oil temp was actually higher than 271, car still pulled hard and didn’t show any weaknesses. That’s just not the right car for a hot lap, very soft in the Esses... It’s a non ZTk car with no Comp seats, try driving that setup at the limit on R7s while holding yourself in. It’s just messy, trust me, I know! I still did a 2:21-2:22 on my warm up lap...the ZR1 is a monster. Operations C7Z is faster in every way, go watch my 2:15.90 video in that car...BTW notice it was raining during my 2:15 laps 🖖
I’ll be back at COTA with a ZTK car and we will see what’s up. Also, Hoosier R7 G loads will increase oil temps quicker than the ZP tire, I know there will be many ZR1s on Hoosiers. COTA and Texas is the true test on a car. Go look on my YouTube, I’ve wheeled almost every car at this point and NOTHING beats the sensations of driving a prepped Corvette...this is why I own 2 Z06s, high five. If there was something better for the money, I would buy it!
The motors new bearings get full oil headroom, 350 degrees.
Limp mode and 260 degree water are worth reporting on, and significant.
Likely ace drivers can still get there. Not furnishing a 24/7 race car is just good business.

Oh stop the BS and speculation and negative comments. Most of use are sick of it.
The facts are if coolant gets to 260 or above you have approached the upper limits.
If Oil temp gets to 320 you have approached the upper limits.
271 for oil temp is not a big deal.
If you don't have facts them keep your opinions to yourself.
I know a little about the driver as one of my Viper friends speaks to him and was with him at COTA a few weeks ago when my friend broke the NASA TT1 record there with a 2:21.604.
Adam is extremely quick. Here he is at COTA running a 2:15 in a C7Z prepared by Gspeed as I recall.

Thanks for clarifying.....I figured he must be someone if he is driving an Aston Martin Vulcan around the track. I would like to know if the oil temps stabilized below 300 degrees of if they kept climbing??......hitting 270 plus degrees in under 5 minutes is something to look at IMO. With all the heat exchangers on the ZR1 and the new grill opening, I'm hoping this is not going to be an issue.
Maybe he can chime in and let us know what the oil temps ended up at. It is good that he is very fast as this will tax the cooling system to the max. Most of the rest of us won't approach those speeds or energy stress so theoretically the temps should be lower.
In south fl you'll reach those temps in daily driving during stop and go rush hour traffic. Outside temp is 95 plus. I remember my 99 ss camaro used to run 220 coolant temp. 2009 Z06 and 14' ctsv always had high oil temps, but that's one reason why you run synthetic. Disburses heat better. I wouldn't worry about it unless the car does!
I paused the video near the end of his session and grabbed this shot of the dash. It looks like it was 27x (278? 276?). In other words, while the oil temps went up quickly they also stabilized in the 270's. We also don't know ambient temp or whether 15W50 was in the car. I wouldn't be worried about this at all.

Good eye on that....I'm not sure how long his actual session was since it got edited when he was behind the Porsche he caught up to. I'm thinking he was out there for more than the 7 minutes or so the video shows.
Anything that can stay under 300 degrees oil temp doing 20 minutes sessions with 750 plus horsepower is impressive, especially in the hands of a fast driver. I'm wondering if the cooling system has some sort of bypass or thermostat to keep the oil hot enough for street use but increases cooling capacity once the temps start to rise??
For what it's worth, he also replied to a comment saying the car passed 500 miles while on the track so for Sean's comment about the oil, I highly doubt it was changed from what the factory puts in it.
Also in my opinion, 270 isn't terrible, but it's also not great. Granted if it stabilizes there, that's good. One thing to keep in mind is that the oil cooler is in the same location as the Z06 so yes, there is a lot more heat exchangers, but the oil cooler is still next to the cat.

i thought in the under car vid the oil cooler was in the same place near cat but had cooling fins vs. a smooth brick. Not certain tho.

What he said!! 271 aint **** for oil temps. Get off the silly koolaid wagons and quite acting like snowflake liberals.
The 2:00 min mark puts the GT3 debate at rest. You can see how far behind ZR1 is initially and how he quickly closes that gap. Almost feels like GT3 is in a different league.

ZR1 oil temp at 271 degrees in two laps??
