2b. Mounting the e-Boost
-
The e-boost is not waterproof and must be mounted inside the
cabin.
-
The e-Boost is designed to be panel mounted with the bracket
supplied. Alternatively the e-Boost can be mounted in a 66mm
(2 5/8 inch) gauge cup, pod or “A pillar” mount.
-
The slim 4mm OD polyurethane hose is only to be used inside the
cabin of the vehicle, it is not rated to withstand engine bay
temperatures. The connecting barb joins the 4mm OD polyurethane
hose to the thicker silicon hose. This silicon hose is rated to
withstand engine bay temperatures and is easier to connect to the
intake manifold.
-
Route the 4mm polyurethane hose through the cabin from the e-
Boost mounting position to the firewall/bulkhead taking care not to
kink the hose.
-
If necessary cut the 4mm polyurethane hose leaving a minimum of
50mm (2 inches) of hose protruding from the back of the e-Boost
cup. Use the supplied “push in” 4mm hose joiner to reconnect the
two ends of the 4mm polyurethane hose ensuring that the hose is
pushed all the way into the base of the joiner.
-
WARNING!
DO NOT LOOSEN THE GLAND ON THE BACK OF THE
e-BOOST UNIT! The 4mm polyurethane hose cannot be replaced
by any other hose type or fitting. Loosening the gland will cause
damage to the unit, rendering it inoperable. If this occurs the unit
must be returned to Turbosmart and repaired at the customer’s expense.
-
Use the connecting barb to join the 4mm OD polyurethane hose to the 3mm ID (e-Boost-40) or
¼
inch ID (e-Boost-60) silicon hose at the
firewall/bulkhead. Ensure the 4mm OD polyurethane hose is pressed all the way onto the connecting barb and that the polyurethane hose
does not enter the engine bay.
-
Route the silicon hose through the engine bay and connect it to a pressure/vacuum signal from the inlet manifold. Use the supplied tee
piece if necessary.
-
Secure all connections with the supplied hose clamps.
2c. Installing the e-Boost solenoid
-
Mount the e-Boost solenoid in an appropriate position in the engine bay with the screws supplied.
-
The e-Boost solenoid is rated to a maximum temperature of 100 degrees Celsius (212 degrees Fahrenheit), ensure that it is mounted a
minimum of 250mm (10 Inches) away from the heat of the turbo or exhaust manifold, otherwise heat shielding maybe required.
2d. Single Internal Wastegate Connection
Most factory turbocharged vehicles use an internal wastegate system to control boost pressure. The e-Boost controls boost pressure by
controlling the pressure signal that the wastegate actuator receives from the turbocharger. Please note that the e-Boost cannot be used to
obtain a boost pressure lower than the standard wastegate actuator’s pressure setting.
If your vehicle is fitted with a factory boost control solenoid it MUST BE REMOVED from the hose that runs between the pressure source and
the wastegate actuator.
WARNING!
Failure to remove the solenoid will cause erratic or fluctuating boost pressure, and
over boosting may occur.
-
Ensure that this solenoid remains connected to the ECU’s wiring harness, If not the “Check Engine” light may be triggered.
-
The factory boost control solenoid is NOT a sensor of any kind, its removal from the wastegate actuator hose will NOT cause any adverse
effects.
-
Some wastegate actuators have two inlet fittings, eg Toyota GT4 (All-Trac) Celica, MR2, JZA80 Supra. Identify the hose that connects
from the boost control solenoid to the wastegate actuator, and block both ends of this hose.
-
Some factory hoses have a small restrictor fitted inside them, if the factory hoses are reused over boosting or boost spiking may occur.
-
Turbosmart recommends using the silicon hose (and reducers if necessary) to connect the e-Boost solenoid.
-
Secure all connections with the supplied hose clamps.
