GFB Atomic Boost Controller (part 3001) - Manual

GFB Atomic Boost Controller Installation
ALWAYS use an accurate boost gauge when making boost adjustments!
Measure the boost BEFORE installing this product, so you have a reference point.
These instructions are for single-turbo installations only. If your car has a twin simultaneous turbo setup (such as that found
in the 1JZ-GTE engine for example), you simply need to follow these instructions and use a tee to split the hose coming out
of the Atomic to each wastegate. If you have a sequential twin turbo, it would be best to consult a knowledgeable turbo
expert before installing this product.
Note that every turbo car will have a different engine layout, so it is
impossible to make these instructions specific for every model. However,
the principle of boost control is the same for almost every turbo car,
therefore all that is required is to identify the parts shown in this guide by
tracing the boost control hoses in your engine bay.
Most turbo cars will have some form of factory boost control in the form
of a solenoid valve in the system (as shown opposite – note that some cars
will have different hose connections, but the principle is the same), the
exceptions being most turbo diesel engines and cars manufactured before
about 1988. These cars will simply have an uninterrupted hose between
the wastegate actuator and the boost source.
1.
Locate the wastegate actuator, the boost control solenoid (if
fitted), and the boost source. Note that the boost source is most commonly
found on the turbo compressor cover as shown, although some cars (such as the 200SX) will have it elsewhere on the
intercooler piping.
2.
Remove the hoses from the wastegate actuator and boost source, and connect the Atomic as shown below. If the
hoses are not a tight fit on the wastegate or boost source, secure them with cable ties.
Ensure the arrow on the Atomic body points towards the wastegate actuator as shown.
•
Do NOT use a manifold vacuum hose as a boost pick-up point.
The boost source must come from BEFORE the throttle body.
•
Do NOT connect any other devices such as boost gauges, blow-
off valves, or fuel pressure regulators to ANY of the boost
control hoses.
•
Do not connect the Atomic to any factory hose that contains a
restrictor. The easy way to test for a restrictor is to blow through
the hose. If it seems overly difficult to blow through, replace it with
a new hose.
3. Leave the factory boost control solenoid in place and ensure it is
still has the electrical connector attached so that no errors are detected by
the ECU. There will still be one hose connected to the solenoid that leads
to the turbo intake (marked solenoid outlet in the top photo), remove this hose from the solenoid and plug it so that dirt
cannot be drawn into the turbo. It is also a good idea to plug all of the nipples on the solenoid to prevent dirt from entering.
The ECU will still drive the solenoid, but it is no longer in control of the boost.
