How do I plumb a wastegate without a boost controller?

Install the Boost Tee in the wastegate pressure line with the wastegate arrow pointing towards the bottom port on the wastegate. Secure all silicone hose ends with hose clamps. Mount your boost controller bracket onto the vehicle, then attach the boost controller onto the bracket with the supplied screws.

Do you need a boost controller if you have a wastegate?

Wastegate spring pressure is the lowest boost level you can reach. Using a boost controller, you can quickly increase boost pressure over wastegate spring pressure. However, you can’t achieve a maximum boost level under the wastegate’s spring pressure.

What happens if you overboost?

Overboost is when the turbocharger runs at a higher pressure (forces more air into the engine) than would be sustainable on a constant basis. The duration of overboost is usually limited to 10-20 seconds and the result is a power gain of around 10%, on average, for that period of time.

Does wastegate placement matter?

In terms of installing an external wastegate in the best possible position, Marty had this to say: “Wastegate mounting is very important in order to maximize the flow and control capability of the wastegate.

What controls the wastegate on a turbo?

In most cases, a wastegate is a relatively simple valve, controlled by a pressure actuator linked to the boost pressure of the turbo. The wastegate is held shut by a spring inside the actuator, but when the boost pressure exceeds the pre-set maximum, it compresses this spring, progressively opening the wastegate.

Do wastegates make a sound?

External Wastegates are responsible for turbo flutter. That fluttering sound, which typically occurs when the throttle is suddenly closed, is the sound of the turbo trying to push air into the engine but failing, so the compressor blades ‘chop’ through the air. You can read more about this phenomenon here.

Can you run a turbo without a wastegate?

While in theory you could run a turbo system without a wastegate by carefully choosing a turbo that will only reach its maximum turbine speed and desired boost pressure at the engine’s max RPM, it’s really not practical in the real world.

How much turbo boost is too much?

If you have a stock engine, with a compressor that is factory set to produce no more than twenty pounds of boost, you shouldn’t modify the system to make it produce much more than 25 pounds of boost. And increase of 5 pounds over stock is probably the limit you should go by.

What happens if my wastegate is stuck closed?

If it was stuck closed, you would spike most likely hard overboost. Stuck open you would be slow getting into boost(REALLY laggy) and you would run wastegate pressure.

How do I reset my actuators?

PRESS and HOLD the DOWN arrow for 10-15 seconds to re-initialize the system. Once complete, the switch should display “027” (Figure 5). Once both sets of control boxes are reset, remove the programable hand switch and install the switch that came with your system.

Where do I mount my wastegate?

The ideal position for maximum flow to the wastegate is to have its inlet tube mounted at as shallow an angle (more than 90 degrees) as possible from the primary exhaust tubes that feed the turbine.

Where should wastegate be mounted?

The ideal location for the wastegate is as close to the turbine housing as possible, and in a manner that provides a good flow path into the wastegate. If this is not possible, the next best location is at (or just after) the exhaust collector and again, in a manner that provides good flow into the wastegate.

Do you need a tune after installing a boost controller?

A: A pro-tune is required when installing a boost control solenoid.
