Which year is the car? If facelift then it could be a rock damage to auxillary heat exchanger, ones for engine coolant ones for IC coolant. If tuned could be a leaking intercooler, they are known to leak after certain boost levels. Or piping.

Lay some pieces of large white posterboard on the garage floor and park over it

It may be boiling out of your cap, landing on the hot V and evaporating. Look for orange residue on the hot V or around the cap. if you do a hard run open the hood and look and see if the cap area is wet.
