Yes, the cooling system. As I feared from the start. Based on my experience with my 1964 T-bird, cooling is almost always the problem with old cars. And it’s often the problem with race cars and high-horsepower cars too. Heat dissipation is a constant battle in any motorized vehicle.
After feet and feet of snow a winter or two ago, it’s quite welcome that summer brings driving weather. At the autocross a while back, though, it was really, really hot–not that I’m complaining or anything. But it was other-end-of-the-spectrum hot. At the autocross, I was lucky enough to bring one recent-vintage car (Porsche 997 Targa 4) and two older cars (1973 914 and 1986 944). Keeping the machinery cool became more of a focal point than when I’m just running the newer car. Even the newer car can hit 250°F+ for coolant temp when running at a race track like Palmer or Thompson on a hot day. Idling waiting for runs at the autocross drives up the temps no matter what, so you get a lot of heat that doesn’t have the benefit of fast airflow like you get when running laps on a race track. So how can we keep things a bit cooler? Continue reading Porsche 944: Keeping cool on a hot day→
