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) ![]() |

My car had an under rear trunk cooler and fan and it was pretty much useless on the track. Before I move the oil cooler up front I put a GT engine lid on. It helped but not a lot. I would make sure your air/fuel mixture is right and try a GT lid if you want but I wouldn't bother with an under trunk cooler. You didn't say, how high were the temps getting?
Also is the intake for your cooler sealed to the cooler so that no air is escaping to the sides? |
