Stalling after full track session

Word of advice - after running laps BEFORE you lose a lot of speed (eg: rolling into the pits or safety areas) put your HVAC on HIGH HEAT and put the fans on FULL.

The car draws air across the hot engine to heat it up going into the cabin and it will help cool off your car faster. It will make you uncomfortable but you can sweat it out with the car.

Also, an oil cooler is definitely needed if heavy track use is a possibility.

Wait you're saying this car has not heater core with coolant by pass hoses supplying heated water for the heater?

Get an oil cooler, bruh.

Car was great today, even though ambient temps were hotter (about 87-89 degrees). Car was feeling so good I even let my instructor run an extra session during one of my cool-down periods. No issues. Will continue to run 100 octane as insurance.

Oil cooler and tune are on my list of mods for sure.

The heater core is heated by the same coolant from the engine which is too hot at the time after racing no?

Using the HVAC to draw heat off the hot coolant (heat goes from coolant to the air which goes into cabin) and thus results in cooler (not cold but cooler) coolant back to the reservoir which can then be accessed by the engine to cool itself.

In the end, the key thing is that we are trying to find a venue to dump heat - the heater core is one way (albeit small) to dump that heat into the cabin air.

The car doesn't magically generate heat from nothing.

I have never experienced it after an autox event, but if it was a hot enough day I wouldn't be surprised that it overheated. These cars are iffy when it comes to staying cool it seems.

Especially with that wimpy little radiator...it seems that if you are going to push this car you need a bigger radiator and/or oil cooler...

Oh yea found out my was due to a loosened vacuum hose from a wild run .. don't want to scare people from autocrossing stock
(Sorry to thread jack)
