1972 Porsche 911T

  1972 and 1973 model 911's continued as the T, E, and S models. The engine displacement increased to 2.4 liters. This was accomplished by increasing the stroke to 70.4 millimeters. In the U.S. the regular unleaded gas necessitated the engine compression ratios to be lowered so the engines would run properly. The S model horsepower was 190, the E model 165, and the U.S. T model now came with mechanical fuel injection and 140 horsepower.

Early in 1973, the U.S. bound 911T cars were fitted with Bosch K-Jetronic CIS Continuous Injection System fuel injection. In CIS systems, fuel is continually atomized into the intake manifold just upstream of the intake valve. Fuel flow is directly controlled by an airflow sensor through a mechanical connection to a plunger which regulates fuel flow. Here's a link to a thorough explanation of a CIS system.

In 1972, the new type 915 transmission had a conventional shift pattern and optional 5 speed. The transmission was upgraded to handle the increased torque of the larger displacement engines. It was stronger and had better transmission oil circulation than its predecessor, the type 901.

To help handling, the dry sump oil tank was moved from behind the rear wheel to in front of the rear wheel. Dry sump oil tank fill access doors showed up on the right rear fender, just behind the passenger door, on the 1972 cars. This access door is a unique feature of the 1972 models, which many collectors consider a nice bonus. Also, 1972 was the last year for "chrome" air intakes and reflector/indicator/taillight trim. In 1973 the trim items changed to black plastic and the dry sump oil tank moved back to behind the right wheel.

To check the oil level in a Porsche 911, first, get the engine up to normal operating temperature. Next, make sure the car is level and leave the engine running. Finally, go to the oil dipstick (conveniently located as shown above, only on a 1972) inside the engine compartment and check the oil level. The dipstick can be trusted over the oil quantity gauge.

Another change for 1972 is the "flag style" or rectangular driver side mirror that replaced the Durant round style side mirror

What looks like another restored 1973 911T Targa, is actually an unrestored, original condition car. This example is a real beauty and certainly something to behold. It's hard to believe that this car is over 34 years old and in original condition. This 'one owner' car has won a few awards lately and certainly deserves them.

  Thanks to the good ol' U.S. safety standards, the 1973 911 U.S. model has the big rubber bumper gards to keep everyone safe. So pretty, huh? At least the beauty of the rest of the car makes up for those add-on protrusions. All makes of cars suffered styling woes during this period.
