Big willow track days and temp issues

[BuntaTypeR]

Yesterday, I went to the track where the temperature started at 90°F and reached 102°F by lunchtime. My Type R FL5 recorded oil temperatures between 250°F and 282°F. I use Amsoil Signature oil, a PRL intercooler, a PWR track radiator, Acuity hoses, and an oil cooler.

Does anyone know the highest safe water and oil temperatures for our car?

I've emailed Amsoil to inquire about the maximum temperature their oil can handle. I've read that 250°F is the max, but I saw a Gridzilla video where the oil temperature reached 302°F. When my oil temperature hit 250°F, I got off the track. During the third session, it reached 282°F, so I stopped. I'm worried about damaging my engine. It's frustrating that I can only run 3 to 4 laps per session.

everything i'm seeing is lining up with exactly what you're experiencing - air flow and the radiator are most important. the hood must be fully vented, stock sucks, and having 2 radiators is more important than oil coolers, though they help too. i plan to add a second radiator and then have a custom shroud made which seals the radiators off from the rest of the engine. THR-W team was running a set up like that at thunder hill, plus they even removed their radiator fans as part of the formula.

I ordered a hood with more scoops.
Is any company selling a second radiator ? How do you do this?

the hood is going to help a lot. haven't seen the radiator solution done aside from a couple race teams. it is certainly fascinating to see all of the R&D in the community but i'm taking my time with all this to see how it plays out until we have some better solutions. in your position, i think it's worth finding a shop who can use the stock radiator and your aftermarket one together and build you a shroud. THR-W told me they also removed the a/c condensor because it blocks air flow. it just depends on how far you want to go to solve the problem. but it does seem doable. i'm curious to see what someone says about safe oil and coolant temps, that i do not know. thanks for sharing your experience

How are able to contact thr-w?
Id love to ask them about the max oil and water temp.

i think amsoil signature (or any other modern synthetic) withstands way more than 250F safely. additionally, i’ve seen people with actual oil temp sensors that state the calculated value usually is higher than the real value.

i would be more concerned and monitoring ECT values rather than oil temps (which are not true readings) staying below 230F. at those temps the ECU is pulling power anyways.

were you running with the heater on at full blast? it def helps

another perhaps more risky solution is the turbo coolant line delete.

Heater was on full blast on all sessions. Nah, it didnt lower the temp lol

Many people much more smarter than me will surely weigh in but... a common theme I notice with every thread that I've personally seen regarding overheating on track- all of them had an aftermarket intercooler.

These folks ain't lying when they say. Miata is always the answer lmfao

i was passing modded miata's that track day. i rather take an ek, crx or eg with a k20 swap.

Ya however all the cars you just listed are going more than 20 min session though lol

Yeah I use Amsoil in my GT350 and it regularly sees temps of 250F-275F from just street driving. Synthetic oils start to break down in the 400F/450F range so you don't have to worry about that. As long as your arent seeing oil temps in the mid to high 300F range then your oil is fine

No cooling mods on my FL5. I saw between 275-285 oil temps in the middle of my session at H2R in Texas. Mid-90's with a slight breeze.

If you're concerned about the engine, you can always get an oil analysis performed at a lab. It'll give you pretty solid info on metal wear, additives, & contaminants.

Dang, I’ll be at Buttonwillow next week and I think temps are going to be 110+. I’m curious how the car will perform with just an intercooler. I see someone I know in that run group you were in (Leo with the Tesla).
