Thanks Mash, I knew I could count on your feedback given your wast experience in that field and racetracks.There is no way that you can do 2 hot laps without overheat on the Ring. I have all possible cooling except water on radiators. 3 extra large radiators for front and back with high current fans and direct frontal airflow.
My oil temps are fine, battery is fine. It still pulls power back at 6:30 if you go for 7:30 BTG. And that adds 10-15 seconds to the timer. Also you consume 60% at such pace within one lap.
You might be able to do one 8:00 BTG and another 8:20 on a single charge. If power wouldn't drop that much with speed and no power limits, it can do ~ 7:05 BTG, but long straights killing it. It's too big track for it.
Salzburgring is better place for it. 2 hot - 1 cold is sustainable sequence with cooling and brake mods to do slightly more than 20 minutes total per charge and you have chargers on the track.
After studying a lot of YT-vids (including yours with Misha at Apex) and forums-posts, I hoped for 2 fast (not max-hot) Nürburgring laps with the help of the mysterious software tweak announced by Chris aka MasterC17. Of course after applying hardware cooling mods like f/r DU oil cooler & HV battery loop water radiator.
Combined with a mild power limiting from the start via MPP cooling party controller this should be achievable with 2 times low 08:xx BTG without trying to set new records, just enjoying a more constant flow and conserving M3s hardware a bit...
Maybe this does not make sense to you, but the quick but smooth ride was always my approach. From MTB downhills to go-kart tracking or enduro and street bike touring to 4WDing in the mountains. I prefer consistency and flow to a more aggressive/abrupt style, that's me having fun with less risk and wear...
Bye Julius
