1996 993 Excessive Oil Heating


Vehicle Information: Year: 96; Body Type: Coupe; Total Mileage: 24000;

I have a stock varioram engine with Cyntex chip in a 77 coupe. I've had a kit put into the oil line thermostat and tried a totally different thermostat which does open at 180 and keeps it there except at the track. This is a dedicated track car now. I have a large B&B cooler in the front RSR bumper with good air flow, a 964/993 cooler under one fender and a Carrera cooler under the other. Still the oil temp creeps up to 250 after about 5 hard laps. It holds over 16 quarts with all those coolers. Also, I have no O2 sensor as the harness I got doesn't have the wires for it. It came direct from Porsche as a cup car harness. As soon as I let off and do one cool down lap the temp drops to 220 and by the time I back in the pits the temp is down to 180. had the gauge checked out. Any ideas?? PLEASE !!
