I spent the weekend at the NASA event at Willow Springs. It was pretty fun, and a very fast track - 125 on front stretch, about 105 or so on the back stretch. Turn 8/9 right at about 90/100 mph. Yowzers. I had never driven on that fast of corners before.
It think it was about 105 degrees out too, and my car started to get too hot in the afternoon sessions. I actually had to stop the 20 minute run sessions early. I was quite surprised by this, as I had previously been concerned that the car is running too cool on the freeways. Hmmm... I'm running a 3.6 with a front mounted Mocal cooler that's 20x6x2 or so. Another 914 there had a 4.0 (from a 3.6) with the factory C2 cooler under the rear trunk AND a front mounted cooler that was 16x6x2 or so. I think my DME programming might still be a little off (too lean) contributing to the heat. I'll have to check it out. Does anyone have any real world experience with the GT engine lids? Do they really make a cooling difference? Anything else to consider besides fuel/timing and engine lid before I start cutting away for a second cooler somewhere? -Steve Attached image(s) |

On a 911 motor, the temp sensor is located at the front of the engine....not quite at the end of it's journey thru the engine. It still has to go thru the spray bar in the cam housings and thus help cool the heads.....the hot stuff. It has already gone thru the engine oil cooler at tthe start of the journey. God knows the temps when it gets sucked up by the scavenge side of the pump.
So....the temp gauge is just an indicator, not a final or the hottest temp of the oil. Personally, I happy as a clam to see a max reading of less that 212 on the gauge....usually, it's less than 185f. That temp will not boil off water/gas, but it will still evaporate it in a hurry. |
