What kind of pressure does a 911 Turbo have?
System, cold and warm control pressures in Bar. Some information is conflicting for the early years, see info source and notes. (Euro Models are followed by asterisk). Entry in “Vacuum Connection” column is the control pressure specified with vacuum applied to the WUR. Note: I have added Pressure Specs for the 930 Turbo below this table.
What’s the maximum tire pressure for a Porsche?
Tire Pressure Monitoring detects a pressure loss of at least 4 psi (0.3 bar). Correct tire pressure at the next opportunity. Observe maximum permitted speed. Information on driving with a collapsible spare wheel after selection in spare wheel menu. Observe maximum speed of max. 50 mph or 80 km/h and required pressure of 51 psi or 3.5 bar.
Can a pressure test be done without running the engine?
You can do the leakdown test without running the engine, but pressure leakdown could be more pronounced with more engine heat. This test will include the WUR. Stopping the engine and closing the valve will eleminate the WUR from the leak test, but still include the check valve, accumulator, injectors, and fuel distributor.
What does the thermo valve do on a Porsche 911?
In addition, 911 SC models use a thermo-valve, which enriches the fuel mixture during starting by blocking the warm-up regulator vacuum which de- creases control pressure. After starting, the valve opens by means of an electric heating element.

What should the voltage be on a Porsche 911 alternator?
The next item to check is the voltage at the battery. This should read a little more than 12 volts with the engine off. When the car is running, the voltage should read at in the range of 13.5 to 14.5 volts with the engine at 2000 rpm.
Why is there a 5 blade fan on a Porsche 911?
Make sure that you reconnect all of the wires to their proper terminals when you are done. In 1975, Porsche implemented a five-blade fan instead of the normal 11-blade one on all the 911 motors. The purpose of this fan was to provide less cooling to the engine, forcing it to run hotter.
Why is my Porsche 911 alternator leaking acid?
If your battery appears to be leaking, then your voltage regulator has probably failed. The battery will usually only leak acid if it has been overcharged at a much higher voltage. If the voltage measured at the battery is more than 16 or 17 volts, then the regulator is probably bad.

When does the indicator light go out on a Porsche 911?
Indicator lamp is dim after starting, and gets brighter as engine rpm increases. Indicator lamp is dim after startup, but eventually gets dimmer and goes out when engine RPM increase. Indicator lamp is dim after startup, and gets dimmer as rpm increases, but never goes out.
