Boiling over
At my last 2 track days I noticed that the coolant boiled over and spilled out from the overflow tank after each session. I have a relatively new OEM radiator fresh coolant. Do you think it is OK or it needs some fixes?
Will at 160 degree thermostat help or I need a "$$$$ and better" after marker aluminum radiator?
Thanks,
Gabriel

The overflow system is designed to expand and contrast. If you don't get overheating, you just had too much coolant in the overflow tank.

When is the last time you replaced the radiator cap? I had the same problem last year, replacing my radiator cap cured it. YMMV

If you were as slow as me, you wouldn't be afraid either.

do what everyone suggested. Putting in a lower thermostat doesn't increase the thermal capacity of the cooling system, it just makes your car run on warm-up enrichment when it should run the standard fuel and spark table.
