Do air cooled 911s overheat?
Air-cooled 911s perform great in colder weather. Logically, you’ll be driving a 911 more in the summer months, when overheating is more common. Liquid-cooling systems mean you can drive hard in the heat with a far smaller risk of running into a problem.
How do air cooled Porsches not overheat?
Air-cooled engines need air to keep the engine its coolest. Porsche engines use a cooling fan to help keep everything flowing. If you own a 911 then with most models, the fan is easy to spot and check. We recommend turning on the car for a moment and watch to make sure the fan comes on.
Can you overheat an air cooled engine?
Air-cooled engines are more likely to overheat. They can also be more expensive to build and the large fans used to cool the engine can take away a lot of power.
Why engines are air-cooled?
Not only does it reduce weight (no water tank, no extra lines and fittings) but also the cost of ownership. By opting for an air cooled engine, we get rid of problems like freezing or evaporating coolant , broken water pumps and water radiators and replace it by something light and readily available when flying : AIR.
What would cause an air cooled engine to overheat?
There are two main reasons why an air cooled motorcycle engine overheats. The first main reason is probably due to the engine working way too hard and the rev is too high. During a high rev, the RPM’s are increased so the friction that’s happening inside the engine also increases.
How much does an air cooled 911 cost?
The motor needed an entire top end job. On an air-cooled 911 engine, this involves rebuilding about two-thirds of the engine. Most SC’s have broken head studs so I thought it was a possibility, but I had my fingers crossed. A typical top end job is around $7-10k.

When did Porsche start to increase the stroke of the 911?
Stuttgart first added displacement to its air-cooled flat six for the 1970 model year, when the 1965–69 2.0-liter grew to 2.2 liters on a bore increase. In the quest to build ever faster 911s, however, Porsche began to increase stroke, as well, creating 2.4-, 2.7-, 3.0-, 3.2-, 3.6-, and 3.8-liter engines between 1972 and 1998.
What kind of crank does a 911 use?
Many of the great 911 race cars won on 66-mm cranks, among them the 911R with its high-strung 220-hp 2.0 and the 911 S-Ts with their 2.3s and 2.5s. What short-stroke flat sixes give up in power, they make up for in the way they spin.
When did the air cooled Porsche 911 come out?
Porsche updated the 911 over the years, adding more power and introducing trims like the Turbo and Carrera that have become everyday parts of Porsche terminology. In 1989, Porsche redesigned the air-cooled 911, creating the 964-gen 911, which was the first to offer all-wheel drive, power steering, and ABS, Autotrader reports.
