ADJUSTING BOOST PRESSURE
1.
Start by setting the “RISE RATE” adjuster completely clockwise to the maximum setting, and
that the “BOOST” adjuster is turned completely ANTI
-CLOCKWISE to the minimum setting.
2.
Start the engine and observe the turbocharger's actuator rod and linkage setup. Slowly turn
the RISE RATE adjuster anti-clockwise until the actuator arm just starts moving off its limit
stopper, then turn it back ¼ of a turn. This should be a good starting point whilst you set up
the peak boost pressure.
3.
With the “BOOST” adjuster s
till in the minimum position, take the car for a drive and
perform a boost run whilst monitoring the boost pressure to ensure everything is set up
correctly and to note the minimum boost pressure the system will achieve.
4.
Increase the “BOOST” setting one f
ull turn clockwise and perform another run to check the
boost. It may take a couple of turns before you notice the peak boost increasing, but
essentially you are incrementally making and testing adjustments until you arrive at your
desired target boost. Please take care to drive the same way each time you test an
adjustment, as different speeds, RPM, and loads can change the peak boost pressure.
5.
Once you have achieved your target boost pressure, you can adjust the “RISE RATE” setting
.This is something of
a balancing act, as changing the “RISE RATE” setting can affect the peak
boost pressure. Increasing the “RISE RATE” setting will delay the opening of the VNT vanes
and will bring boost on harder and earlier, but may also result in over boost or spiking if you
go too far. As with setting the peak boost, make incremental changes and test the result.
You may need to reduce the “BOOST” setting if “RISE RATE” is increased significantly.
6.
If you are not comfortable with making these changes to your boost pressures which can
cause engine or turbocharger failure. We strongly recommended you seek out professional
help from a tuner or workshop to install this product.
