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) |

Steve - glad to hear you had a fun day. I'm really starting to jones as I've only done a few track events all year so far.
What kind of ducting setup does your cooler have? I am kind of surprised that a cooler that large would not be adequate even in summer Willow conditions, if the airflow and engine tune etc. were all correct. I have a similar sized cooler up front of my car and have never gotten it over 200-ish even in 20+ minute sessions under the most brutal conditions; granted mine is a 2.2S spec vs. a 3.6... Also I'm wondering if there is sufficient flow to and from the cooler? I think most guys recommend AN-16 lines for 3.6 applications that see track use. (IMG:style_emoticons/default/confused24.gif) I wouldn't freak out over 245° oil temps but it would be a good idea to run synthetic oil, and keep an eye on the gauge in case it ever goes beyond 250... |
