Edit: I think my shop was planning to use the S54 BMW Tstat on the S65, which is 59 C

i wouldn't bother. it is going to take longer to reach optimal running temp, but it isn't going to curb any kind of heat issues beyond that. it probably doesn't open wider, increase flow, etc., it probably just opens sooner. so after the initial warm-up, its not going to make a difference the rest of the day. i actually want the car to get to optimal temp faster, so i'd personally not go for this lower temp thermostat. my car tends to run cool anyways.

the oil diverter works differently becuase (from what i understand) it increases the volume of flow through the system. its less of a "pinch point."

With the oil diverter my car still reached 285* temps.

I think the diverter contribution is helping cooling off quicker. My car does cool off rather quickly when I short shift or take a cooling lap.

However, full pace at WGI I did manage to get to High temp warning.

Interestingly enough is that at PMP, NYST and LRP I no longer get the temp warning. Only at WGI.

I have the full do88 kit, oil diverter and OEM T-stat

That is very surprising that with the foll do88 kit your car is still over heating. I have run at VIR, Summit, and Road Atlanta in 90+ temps with just the do88 oil cooler and Koyo radiator, never had an issue. I do have my hood vented so that helps a little

I don't think the supercharger is helping temperatures for rhyary

Yes, my car is supercharged and temp management is part of the fun.

[turbo_joe]

Didn't know you were SCed, that explains it. I think our cars are impossible to keep cool with a SC thrown into the mix

[Datka]

I sold my car not too long ago. Supercharged e9x m3 can be fun to drive in a cool weather , but anything over 70f was giving me a lot of overheating issues, loss of power due to the engine heat soak.
And that issue didn't go away after installing do 88 cooling stuff, hood and fender vents.

VIR North Course was a blast, made improvements on all grading areas for D group thankfully. Next time I'm absolutely bringing an ice cooler with cold water and maybe popcicles, I had to tap out on the last two Sunday sessions due to heat fatigue just melting my brain and killing my track performance.

Thankfully one of my friends had a canopy, but warm parking lot water didn't help me regulate body temps as much as I needed.

Probably time to start logging efforts so far in an HPDE post.

I did 5 mile at thunderhill on Monday. High was in the low 100's. We had ez ups and a buddy bought a couple of bucket misters. Which helped immensely. I was sold on them instantly! highly recommend. There's a few brands out there to share with existing batteries for different tools people may already have but these were ryobi ones.

I'm waiting on a Milwaukee M12 one. hahaha

[e36clubracer]

Those misters are pretty awesome!

We did the 24h of lemons race at THill in 2021 during memorial day. Never again, it was 115 degrees in the shade that Sunday. It had to be 130+ in the car. Even with coolshirts it was hardly tolerable for just an hour. That place is a hellhole from basically April to November.

I've come to realize I dont want to do track days at Thunderhill between those months even in my street car haha.

I'll stick to Laguna/Sonoma during summer months.

[SAMM3Y]

Lol, I don't think it's that bad… I could imagine it is during a 24hour race when you're in the car for hours but 20 minute sessions… meh. Typically doesn't hit triple digits till 3-4pm. Hydrate up and no need to take it easy on the out lap. Those tires are plenty warm lol.

Sorry to hear about your 2 missed sessions. Perhaps consider the Cool Shirt technology for hot southern tracks. Road Atlanta in summer can be even hotter than VIR due to no shade.. And that's saying something.

I had thought about picking one of these up, even if I just used it in between sessions it would be a good system temp regulator

Years ago - as an instructor for PCA - I saw students develop brain fog on hot days in the Southeast caused by mild dehydration and electrolyte loss. A good idea is to eat a banana for breakfast (to potassium load) and even take a bottle of Pedialyte (Gatoraid is sugar loaded). Eat some more bananas at lunchtime too - especially at Southern Tracks like Roebling Road, VIR, Carolina Motorsports Park, Sebring, Lowes Motor Speedway etc. where there's a total lack of shade in the paddocks. Drink lots of water... If your'e not going to the Men's room every 90 to 120 minutes then your fluid intake is too low compared to your fluid loss through sweating. This condition (dehydration) can be quite dangerous when combined with HPDE risks. Loss of consciousness (fainting) from heat stroke can also happen suddenly.

[SAMM3Y]

Yeah. Bananas, coconut water, liquid iv, Gatorade, gallons of water and salt pills.

[Cmassey3]

I had an almost good hydration routine of about 6L/day and added in Gatorade on Sunday, but I've gotta pair that with a proper nutrition routine too. I think I had compound fatigue heading into Sunday from not being 100% on the ball with the water/hour ratio on Saturday. These are all great suggestions!

Call me a wimp, but I hate being hot.

People acclimate to it too, if you spend more time in the heat the less it'll bother you. There's those sicko's out there who run marathons and Ironmans in extreme weather 😂 they train for it. I like to "train" for it too but it typically entails 18 holes and beer.

[roastbeef]

This is the only work or "training" I do on a hot day.
