Variable Controller Tuning; Controller Operation Example - Snow Performance 20010 Installation Instructions Manual

Maintenance –
Remove nozzle(s) and clean screen filters at
least once per year using carb cleaner.
The Boost Cooler® has been designed to operate with high
concentrations of methanol. Oil or other additives are not required
for system lubrication.
For best performance, cooling, and system life it is recommend that
Snow Performance Boost Juice™ (#40008) be the exclusive fluid

Variable Controller Tuning

•
Rotate the MODE switch
clockwise to select
BOOST mode.
•
Adjust the START boost
level first by turning dial clockwise to ½ to 1/3
boost. This sets the boost pressure required to activate the injection
system.
•
Adjust FULL dial to the maximum boost the vehicle can make.
•
If bucking or bogging is experienced at the onset of injection,
increase the start point. If it is felt in the higher RPMs, increase the
full point. Often a full point below the vehicles max boost can be
used.

Boost Press ure psi
The left arrow on the chart shows the START dial at 4 psi and the FULL
dial at 12 psi. At 4 psig of boost pressure the pump will operate at 10%.
At 12psig of boost pressure, the pump will deliver 100% of injection
pressure. For boost pressure readings between the START and FULL
settings, the controller will linearly adjust the pump pressure as shown on
the graph.
