I was talking with one of the Porsche Cup Car mechanics and he told me of a new feature in the later year cup cars. They now have a pressure sensor in the crankcase that is tied to the master alarm. Once a baseline is determined they set the warning light to go off once that number is exceeded.
Seems like a great early warning to impending doom. Those who have AIM dash or Race Logic could do the same.

It's a great sensor to have for on-the-fly diagnostics, which is an important factor in a car that sees time at 12+ hour races (Le Mans, Daytona, Sebring, Thunderhill, etc). For a club racer or an HPDE car, it's nothing a post-event compression/leakdown test won't clue you in on.

Porsche people are funny. I am reminded of the aftermarket kit you can buy for the 996 engine which is essentially a sensor that alerts you that your IMS bearing has failed and you need a new engine.

This does bring up the question of unusual alarms. For instance is anyone running a coolant pressure alarm/gauge? It would have saved at least 1 race motor on a team I was crewing with. A screwdriver had nicked a heater core hose, and slowly let out all the coolant. Melted the head and block.

In theory, yes. Assuming you notice the little LED flashing at you, and you immediately stop and call a tow truck, there is a chance that you may only require a $2,000 repair instead of a $20,000 repair.
