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) |

Thanks for all the good tips. My to do list is growing quite long and I think I'll be able to solve this problem. I just stopped by Deiters here locally and they had some other good ideas.
For one, they said my thermostat is probably too small and I should confirm it is -12 all the way through or get the Troutman thermostat. Anyone have Troutman contact info? Couldn't find them on the web. Plus, they mentioned that I needed to make sure that the oil was flowing through the cooler going in on the bottom. I'm honestly not sure which way this is going now, but they said this can make a big difference (otherwise air gets trapped in the cooler, not oil). My current to do list: - confirm car isn't running too lean (dyno this weekend) - confirm oil cooler and thermostat are being filled from the bottom - finish building front valence, seal inlet air to cooler too - confirm/replace thermostat size - add "flap" to create low pressure on oil cooler exhaust air. My plan here is to cut further cut the trunk a little more on the sides, but not the front, then just fold it down at 45 degrees. - add underside engine flaps (good reminder, I've been meaning to put these back on!) - use 20/50 oil, not 10/30 oil later if that hasn't worked: - add fans behind cooler - try less restrictive mesh - add second cooler somewhere - go to -16 |
