Any tips on fabricating a radiator & intercooler duct setup for this? As you can see a lot of air can escape on the sides. But there are support pieces and crash bars and harnesses everywhere that would make putting anything there quite difficult.

Alright voodoo cooling experts….(ahem @5.2 liters of democracy and @honeybadger) I think the time has come for additional preventative measures. Hood vents did me good for a long while but yesterday at Buttonwillow I hit 270 degrees indicated oil temp. Granted, it was 85, sunny, a calculated (not true) reading, and we were pushing it hard but 260+ is definitely uncomfortable territory.
Shane, what do I need to plumb a 960? I’ll duct it like yours (guess I need the cad for Send cut send too) but I am keeping the AC condenser for now. Kevin, am I being dumb not touching the water/rad system? That is totally OEM.

Not those guys, but what was CHT?
I wasn’t paying super close attention to CHT - the oil temp reading had me glued to it - but I don’t think I noticed CHTs were higher than 235.
Plus you count as someone with enough knowledge. Sal too
Ahhh. this is some GREAT data. thank you for sharing. I suspected putting coolers in front of the rad would affect efficiency and I think your data shows a lot of credibility to that. If im reading your charts right, you're under 10 degree difference between inlet and outlet. that's gotta' be pretty inefficient. I'm curious to see what I am measuring after adding more sensors. I'm planning on doing the same - measuring at inlet and outlet.
Would be super cool to try testing the oil cooler behind the rad too
I'm actually not too uncomfortable with 260+ oil temps with a high quality oil. I've run Amsoil Dominator in my car for years - before the latest build, I regularly saw 260-280 temps and my oil analysis never showed issues in 3-5 hours of run time. More than that and it started to break down.I analyzed every oil change, so I am fairly confident in the results.
That said, being in the 215-240 range with oil temps is ideal based on my testing. Wont stress anything by over cooling the oil and not hot enough to cause issues.
Re: water cooling. I think before I give any advice with confidence, I'd want to know what cylinder head temps you're seeing and what your real water temps are. Ideally below 200 degrees water temps, CHTs below 230, etc. Water temp needs to be measured separately of course since the OEM CHT sensor isn't exposed to water.
All in all, I'd be more concerned about water than oil at your temps. if you start seeing 280+ peaks during a session, then I'd get worried.
@Voodoo Stoned my man! I was just thinking of you the other day. Hopefully I didn't will any temperature-based anxiety into existence!
I feel similarly to Kevin regarding the temperature. I'd be curious how much worse those temps would be though if it were 100 degree day at BW but I'd still bet it wouldn't hit 280. With that being said, I'm going to do a write up on everything I used for my ducting which of course will still include free access to the files. What I did just find out is SendCutSend changed their tolerances so now I have to revise said files otherwise there are bend errors. Once I resolve those I'll probably start a new post since I've had several request in the last few days. More to follow!

Short log when learning, cold oil from startup giving 20deg drop across the radiator. So yes as the heat load in front increases the efficiency dives.
You rock!
IMO, the water temp is a bigger deal than the oil. Water temp moves around quite a bit around the track, but the mass of the head gives a fairly clean signal and, ultimately, the CHT is what the ECU uses for knock prevention. I'd try to get that down to 200-210*. In doing so, you'll pull heat out of the oil, too. Reducing water temp will significantly influence oil temp, but reducing oil temp will have a smaller effect on water. Oil just can't transfer heat as fast as water.
It was pretty warm on Sunday. I was east of LA, not north, but it got a little miserable mid-day. If you can cool it in those conditions, you can cool it in about any.
If you're on track and have no other way of cooling, then at the end of the straight, lift and coast for 1 brake marker. Zero throttle and just coast. You'll find you can brake a little later. It takes temp out of everything, engine, tires & brakes. It's often a 1/2 tick faster if you're not on stickers.

I would like the relocate the coolant expansion tank to help the airflow from the back of the radiator to the hood vents. Can’t find any decent online though
Have you spoken with @AJ Hartman about this. He has a kit for the S550. It might work or need a small tweak to fit yours.

I have, he said the brackets won’t fit the s197. Didnt mention anything about the coolant plumbing/routing.Have you spoken with @AJ Hartman about this. He has a kit for the S550. It might work or need a small tweak to fit yours.S550 Mustang Coolant Reservoir Relocation Kit

I don’t know if the s197 and the s550 use a similar coolant setup.
I’ve found a decent battery relocation kit which frees up the space needed
Some good data on fan shrouds:
This is interesting, has anybody tried removing the top and bottom panels on an oil cooler duct?
Two quick questions.
(1) What is this radiator with a smaller surface area but more depth that keeps your car's CHT so ridiculously low on track in max heat? Does it drop right in, or did it require some fabrication?
(2) Do you run an oil cooler at all?
Sorry but would you also be willing to dm me the cad aswell if you wouldnt mind.
Make that three - me too please
