Yeah it is my forth time in a row doing the event (twice with my R33 GT-R, twice with the Supra).Looked like a great weekend aside from limp mode.
Is that a z4 parked next to you in last photo?
That looks awesome, no wonder you went to so much trouble to get there
Such amazing cars and must be quite the experience to be part of that .
I'm jealous of the beautiful surroundings and the obviously fun weekend in general... but those temps make me really jealous right now!Last year done the same track with my supra when it was 100% standard and I never ran into problems. Even the track was at that time 25 degrees celcius and sunny. This weekend was only 19 degrees and cloudy.
No did not find yet what caused the limp mode.

I'm not surprised you didn't have problems when it was 100% stock at those temps... I'm not hitting limp mode in my commute in 43C air - figure the roads are likely above 50C! Although far less stressful for the engine than a track day obviously, since it's high speed all the way (until the radar detector goes off at least).
I am also not hitting limp mode on the normal roads when doing a pull. As you mentioned... it is less stressful for the engine and on the road... it has the time to cool down during pulls.
My mate (who drives the white supra on the pictures) has his Supra stage1 tuned till 480HP and was not running into limp mode.
We both go to the same tuner... but he also did not push his supra as hard as I did on the track.
What I noticed during track:
Seeing those numbers... I see we are hitting coolant problems.
- oil temperature at the filter: 106-108 degrees celcius (but raises till 112-115 degrees celcius)
- engine oil temperature: 94-95 degrees celcius
- engine temperature: 87-90 degrees celcius (but raises till 96-100 degrees celcius)
- Intake temperatures before throttle: 87-97 degrees celcius (but raises till 147 degrees celcius)
- intake air temperature: 35-40 degrees celcius
- average coolant temperature: 87-89 degrees celcius (but can reach 95-100 degrees celcius)
- gearbox temperatures: 76-78 degrees celcius
- radiator outlet temperature: 55-60 degrees celcius (but raises till 68-78 degrees celcius)
Unless other people say this is quite normal to keep it up for 20 minutes track sessions and cooling down till next session 40 minutes later
Yes I do. And yes after around 3/4th of the session... the air conditioner can't keep up anymore and it gets warm in the car.Geert,
Are you running the air conditioner whilst tracking, otherwise my hunch is going for better track oil to keep engine temps down.
I have started to notice a correlation.Yes I do. And yes after around 3/4th of the session... the air conditioner can't keep up anymore and it gets warm in the car.
Sticking currently here to the 'gazoo racing 0W20 SN C5' oil:
- Main reason: we are not sure yet what happened to the engine + 0.0 feedback from Toyota
- 99% of the time it is a daily, so driving the recommended oil
We are looking into decreasing the temperatures, but that will be somewhere for during the winter
