Finally started doing Blackstone oil analysis on the new motor. This sample was taken after my two day track weekend where I beat the hell out of the car for two days on track. Oil temps hit almost 280 towards the end of each session.
Good to know even the standard non synthetic VR1 can take this and that the motor is healthy. I'm moving to synthetic VR1 for my next event to see if there is any difference.

Definitely a good oil report. And it supports my theory that oil should be changed every track day/weekend. Wear metals are at a level as if the oil went over 3k miles...
The viscosity at 100*C seems a bit low for a 20w50 though. Usually that's 20.

Track day number four with the new build was yesterday. I'm starting to be much more comfortable with the car and it's showing. I broke my personal best by almost 2 seconds and now approx 1.3 secs away from my goal. Super happy with the car, it's freakin' fast as hell, I'm going Hans device shopping this weekend because of it.
I'll do a more detailed write up with data and such in a couple days once I get some time. For now, here is a video of my new personal best 2:01 lap time.

I was able to install my JDM fog deletes before this last track day. I got all excited when I did because the difference visually of how much more of the oil cooler is in direct air now is HUGE.
However, I just overlayed data from yesterday and a session last month with comparable outside ambient temps and the oil temp is *almost exactly the same*. Follows basically the exact same plot... so yea, the deletes don't help.
Much disappoint. I think maybe I need to make a custom duct to force more air into the cooler now. The OEM duct doesn't seem to channel as well as it could for this cooler.

So... guess what happened again? Damn car fritzed out again and lost power. Car was solid all day long and in the 2nd lap of my fourth session, every time I shifted to 4th under WOT the car would fritz out and loose all power, just like before. However this time it was repeatable and not just a one time thing. It was more dangerous this time as well because I almost had a C63 run into the back of me going down the straight since I was hauling *** one second and then the next, nothing.
ONLY happened in 4th gear and after doing that four times while trying WOT in 4th it all cleared up on it's own and I was able to go 100% the rest of the session. So odd that it just clears up on it's own. Now that I know it only does it in 4th, I'm going to start looking at any gear/speed related tables in the ECU.
Here is one of the instances caught on log: https://datazap.me/u/razorlab/thunde...zoom=7510-7949

Time for a fan
Hey I have been watching you build since almost the beginning and have enjoyed and learned lots.
*Warning blasphemy* you need to put a fan on your oil cooler to help with temps. Many people say it will not make a difference but I have put one on my SST cooler and have done a bunch of testing with. I have two temp sensors, one pre and one post cooler. After getting it up to temp 165+ and driving constant hey speed 100km for at least 5 mins, so the temp stabilizes with about 35f cooling difference. I turned on the fan and within 15 seconds the cooling temp difference increases to 50f.
I made my own bracket and put on a none name brand fan.
The conventional thinking is more air hence why you did the delete but the mechanics work based on pressure differencal of the air pressure. A fan will not move air faster than you can drive but allows more air to pass through. It may seem weird but I promise you it works and can you think of a cheaper fix for 50$
Keep up the great work!

Brian, your oil temp does at least seem to stabilize. And the max was 264?. Can you find a group that does 30 minute sessions and see if it continues to climb? Ideally, you'd prefer to under 250, or even 230 with the oil. But for 20 minute sessions, you're not gonna hurt it getting up to 260-270.

The second session, where I did my personal best, and what the video above is from, I saw a max oil temp of 257*. It was around 45-47* ambient outside.
My last session, which was around 2pm, it was approx 55* out and highest oil temp was 263* on the last lap but looking at the data the last three laps the oil temp was around 3-4* of each other. So it stabilized.
I'm going to another event in two weeks and it looks like it's going to be around 80*. And next month I am going to an event and doing the full 5 mile combined courses for the first time. Should be able to get some interesting data from that one. I already know I'm not going to be able to bring enough fuel for the whole day.

Seems like it does follow ambient temp delta though. Might be an issue on an 80-90* day.
