ACHIEVING YOUR TARGET BOOST PRESSURE


There are various factors involved in achieving your target boost pressure including.

-

The size of the spring fitted in your wastegate i.e. the boost pressure achieved by the wastegate spring only.

-

The desired level of boost pressure and the difference between this and your wastegate spring pressure.

-

The size of your turbocharger and wastegate and the resulting exhaust manifold backpressure in your system.


Turbosmart recommends the ideal setup for achieving your target boost pressure is to use the Power-Gate60 in conjunction
with a Turbosmart e-Boost controller.

IMPORTANT NOTES ON SETTING THE WASTEGATE SPRING PRESSURE


A stiffer spring should only be used when necessary. The Power-Gate60 allows for different combinations of spring pressures. All
springs that are adaptable with the Power-Gate60 are shown in the table below. The tuner can use combinations of up to 3 springs to
achieve the following base boost pressures. To aid in the identification of these springs they are supplied colour coded. If this colour
coding is not clear please use the dimensions in the following table to identity the wastegate spring. Please see the following detailed
instructions on setting your Power-Gate60

’s spring pressure. The springs chosen should be rated to the lowest boost level desired.

Changing the springs

WARNING! Fitting a heavier wastegate spring may 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 spring, before increasing your boost pressure again.

1)

Remove the wastegate from the exhaust manifold. Use CAUTION! The wastegate may still be HOT!

2)

Hold the cap down in a press or vice. Using a 5mm Allen Key, remove the M6 Socket head cap screws that secure the upper
wastegate cap. WARNING! The cap is under spring tension, wear safety glasses and remove with care! Slowly back off the
vice or press and remove the cap.
