TROUBLESHOOTING
The following points should be checked if you find that your engine is over-boosting, under-boosting or the boost pressure is fluctuating
erratically. Please note the following checks will cure 99% of problems experienced when fitting a Turbosmart E-Boost Street.
-
Check that the E-Boost Street solenoid is installed correctly.
- Ensure the factory boost control solenoid is not connected in the hose between the pressure source and the waste gate actuator
- Ensure the length of the waste gate actuator rod has not been modified, refer to the manufactures specifications
- Check to see if the E-Boost Street solenoid is not blocked or contaminated with dirt, oil build up or debris
- Check the joining hoses for splits, cracks or loose connections and ensure they are not blocked, kinked or restricted, particularly if
the existing hose was reused
- Pressure test the waste gate actuator for leakage, the diaphragm or housing may be cracked or split
- Ensure the smooth and free operation of the waste gate arm in the turbo exhaust housing.
- Check that the hose between the E-Boost Street and the inlet manifold is not obstructed, broken or kinked.
- Check that the OBS is set higher than the boost pressure you are aiming for.
- Check the Blow-off Valve for leakage, some are used as over-boost valves
- Gate pressure maybe set too close to your desired boost pressure
- Ensure correct sensitivity setting.
- Check to see you can achieve constant steady boost with only the wastegate actuator connected directly to the pressure only
source on the turbocharger.
