Is there a pressure drop between Turbo and throttle valve?
Is there a pressure drop between Turbo and throttle valve?
Hello, The car symptoms are reduced power, and it idles rough. The 17705 Pressure drop between turbo and Throttle Valve (check D.V.) has been a constant error, while the misfires and lean code errors have come and gone.
What causes the injector to increase effective pressure?
Fuel Pressure Explained. Effective pressure is what injector flow rate is ultimately based off of. When an engine is idling, there is a vacuum in the intake manifold. This vacuum pulls fuel out of the injectors, and increases the effective pressure across the injector to a pressure higher than the rail pressure itself.
How does a return style fuel injector system work?
Return style systems hold a big advantage in that with a vacuum/boost referenced fuel pressure regulator, the system can maintain a CONSTANT effective fuel pressure, which can extend the range of fuel injectors and help them function at lower fuel demands as well.
Why does fuel pressure rise when idling at 20 inHg?
When idling at 20 inHg, this means effective pressure will rise to 68psi because the vacuum in the manifold is adding 10psi to the rails 58psi. This requires injectors to pulse shorter so as to not overfuel the engine and cause a rich condition.
Why do I need a turbo boost sensor?
The Turbo Boost Sensor measures turbo manifold pressure to the ECM, and is used to calculate air density and the required fuel delivery for optimum combustion. If it fails, the system may not add fuel under boost and can result in loss of power and possible engine damage.

Can a stock aspirated engine be turbocharged?
We know at least a dozen people who have turbocharged the stock naturally aspirated engine and all of them have eventually blown them up because of a minor tuning issue or part failure. As cheap as the turbo engines are, it’s silly to do it any other way.
