Installing the E-Boost Street Solenoid
- The E-Boost Street 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.
- Mount the E-Boost Street solenoid in an appropriate position in the engine bay with the mounting kit supplied.
- Fit the rubber grommet inside the mounting plate. Slide the sleeve inside the grommet. Use the M3 screws to bolt the solenoid to the mounting bracket – Note use loctite on the threads to secure. Use the M6 screw, washer and Nyloc nut to mount in a suitable location in the engine bay.
- The E-Boost Street head unit is capable of controlling two solenoids. The use of twin solenoids is not necessary but is recommended in twin turbo setups on V configuration engines as this reduces the length of hose required for plumbing which aids in response and control of the wastegates.
- The solenoid must be connected to a pressure only source which must be located before the intercooler, ideally off the compressor cover of the turbocharger. The air temperature before the intercooler is less affected by ambient conditions which will give you more consistent boost control.
SOLENOID HOOK UP METHODS
WARNING! Changing to different connection method can cause a higher than expected increase in boost pressure. Turbosmart recommends adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure achieved by the new setup before increasing your boost again.
Note: If your vehicle is fitted with a factory boost control solenoid, the hoses that run from the pressure source and to the wastegate actuator must be disconnected. Leave the solenoid plugged into the wiring loom so that the ECU is not affected. Failure to disable the factory boost control solenoid and hoses will result in erratic or fluctuating boost pressures which could damage your engine.
INTERNAL WASTEGATE CONNECTION
WARNING! Changing to different connection methods can cause a higher than expected increase in boost pressure. Turbosmart recommends adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure achieved by the new setup before increasing your boost again.
Note: If your vehicle is fitted with a factory boost control solenoid, the hoses that run from the solenoid to the pressure source and to the wastegate actuator must be disconnected from the solenoid. Leave the solenoid plugged into the wiring loom so that the ECU is not affected.
Most factory turbocharged vehicles use an internal waste gate system to control boost pressure. The E-Boost Street controls boost pressure by controlling the pressure signal that the waste gate actuator receives from the turbocharger. Please note that the E-Boost Street cannot be used to obtain a boost pressure lower than the standard waste gate actuator’s pressure setting.
Some factory hoses have a small restrictor fitted inside them, if the factory hoses are reused over boosting or boost spiking may occur.
Secure all connections with hose clamps.
Single solenoid, single turbocharger hook up (Basic single internal wastegate setups)
Port (1): vents pressure from the solenoid. Connect this hose to the intake side of the turbo, between the air cleaner and the inlet of the turbocharger. Otherwise connect a short piece of the silicon hose and face the vent downwards to stop water or debris
entering the solenoid.
Port (2): to the internal wastegate actuator
Port (3): to pressure only source
