What is normal turbo boost pressure?
6 to 8 pounds per square inch
The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (psi). Since normal atmospheric pressure is 14.7 psi at sea level, you can see that you are getting about 50 percent more air into the engine.
What causes high turbo boost pressure?
The Temperature of Ingoing Air A major factor that also contributes to the power output is the temperature of the air entering the engine. For instance, if one of the cars has a smaller, less efficient turbocharger, it will tend to work harder and spin even faster in a bid to attain the 20 psi of boost.
How do you check turbo boost pressure?
Simply remove the turbo inlet, attach the boost leak tester, hook the tester up to an air compressor, and allow the system to pressurize. From there, you can listen for leaks, or spray windshield washer fluid on your couplers/vacuum lines and look for bubbles that would indicate leaks.
What happens if you run too much boost?
Increasing boost (within reason) will force more air into the engine, so more fuel can be added to increase the power. So in general, if you add more boost and have an engine tuned to suit will give you more power. Too much boost can cause turbo or engine failure.
What happens with too much boost?
Can a turbo get too much air?
You can’t get too much air flow. Air flow is based on the displacement of the engine. In this case, it will take 5. 9 liters per two revolutions.
How do you check if the turbo is working?
There are a number of signs you can look out for to tell if your turbocharger has blown:
- POWER LOSS.
- WHINING ENGINE.
- EXHAUST SMOKE.
- CHECK ENGINE LIGHT.
- OIL/LUBRICATION.
- DAMAGED SEALS.
- FOREIGN OBJECTS/DEPOSITS.
- WEAR & TEAR.

What to look for in a turbo boost system?
The two most important parameters to look at are the desired boost pressure and the actual boost pressure during a test drive. The first thing to see is if the boost reaches the desired level. If the boost is low, it is a sign there might be a leak in the system.
Why is my wastegate not relieving turbo pressure?
Oscillating turbo boost pressure. When the wastegate is not relieving pressure on a consistent basis, it will commonly cause the boost pressure inside the turbo to oscillate rapidly.
Can a low boost Turbo cause low power?
Since boost is created by the heat of expansion, anything that can cause low power will create low boost (ex. injectors, EGR, exhaust leaks, fuel pressure and quality, etc.). Before replacing a turbo for low boost all other systems must be tested. Verify that MAP, BARO, EP PIDs are within 1.5 PSI with Key On Engine Off (KOEO).
