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
I’ve always noticed how race car tires have a very different attitude than street car tires. They are often wider and sit under beautiful fender flares. But they also seem to have a bit more tilt in them where the bottom of the tire sticks out further than the top. I’ve lately discovered this to be called “negative camber”. Camber is the tilt of the wheel around an imaginary axis line that would run either between the two front wheel centers or the rear wheel centers. When the top of the wheel moves in toward the center line of the car and the bottoms move outward, that is “negative camber”. The opposite is positive camber.
The last two days involved getting most of the bits that came with our purchase of the car. The prior owner is a very nice and clearly quite diligent person who carefully acquired the many items needed to convert a 914-4 to a 914-6. Having just watched Van Svenson’s 40+ page tutorial on how to rebuild a 914 motor in gory detail, I’m starting to understand the “signal” that I have much to learn and that real motor work is not for the faint of heart or budget. At least it was a good primer for me to think long and hard about what to do with two 1.7L motors and a 2.7L 911 motor…
Here are the bits that are now stored away. Everything except the 911 motor is present and accounted for.
Nearly forgot two headlights (confirmed to work) and a pile of articles, books, and 914-specific documents. The second one on top caught my eye immediately – how to fix the shift feel of the 914 so it is crisp! Looks like I have some work to do.
