SPRING REPLACEMENT
The Race Port has a variety of springs to suit different vacuum levels. Different tuning levels produce different levels of idle vacuum.
The Race Port is fitted with a standard spring which will remain closed until the engine produces more than 18 in/Hg. Turbosmart has a
range of springs to suit different vacuum levels to ensure high levels of response from the Race Port.
1) Remove the Race Port off the intercooler piping
2) Remove any pressure nipples in the top cap. Hold the cap down in a press or vice. Unscrew the locking collar. Slowly, back
off the vice or press and remove the cap.
3) Select and install the required spring or combination of inner and outer springs into the piston assembly.
4) Ensure that the diaphragm is inside the diaphragm groove.
5) Slowly push the top cap down on the lower diaphragm housing in a vice or press. As the cap reaches the diaphragm, line up
the notches in the cap (Figure 1) with the cut outs (Figure 2) in the lower diaphragm housing. Carefully push the cap down till
the cap is home on the lower diaphragm housing. Reinstall the locking collar and tighten with the provided locking tool. Make
sure that the cap is clamped down while tightening the collar.

TROUBLE SHOOTING
The following points should be checked if you find that your engine is dipping below normal idle, stalling or if the Race Port is functioning
poorly. Please note, the following checks will cure 99% of problems experienced with a Race Port.

Check the vacuum hose for splits, cracks, loose connection, kinking or any obstruction – old or fatigued hose may collapse under
vacuum causing an obstruction
 With the engine running remove the vacuum / pressure hose from the nipple in the cap of the Race Port, there should a loud
hissing sound. The engine should idle poorly, double check by covering the end of the hose with your finger. If this does not occur,
the hose could be blocked or crimped. Check the hose and replace if necessary.
 Ensure that the vacuum / pressure source is not shared and that the vacuum source is directly from the inlet manifold
 Check the seal between the adapter and the Race Port – ensure that there is no gap between the Race Port base and the weld
flange
 Check the join between the adapter and the intercooler pipe for leaking
 Ensure that the right spring is installed in the Race Port for your engine’s vacuum level
