How to Install a Boost Gauge on a Turbo

Written by justin wash | 13/05/2017

A boost gauge will help you understand how your turbo is working at any given moment by providing you with important information about the boost level that it is running at. A boost gauge is an easy to install and easy to maintain piece of equipment that most cars with turbos could benefit from. Keep an eye on your turbo's workings by installing your own boost gauge at home.

Lay out the equipment that came with your boost gauge. You should see a gauge, vacuum line, T clamp and electrical wires.

Locate the vacuum line running off of the turbo. Cut the line and insert the two ends onto the far ends of the T clamp that came with your gauge. Attach the gauge vacuum hose to the last connection on the T clamp.

Following the wiring of your car, run the vacuum hose for the gauge to the cabin. Be sure that the line does not kink or get wrapped around any wires or obstacles.

If your gauge is lighted, run the wires it came with into the centre console and solder them to wires of the same colour that are only powered when the ignition is on. You may test wires with a voltage meter to figure out which ones are right. This will keep the gauge from continuously lighting up and draining your battery.

Attach the vacuum hose from the engine bay to the back of the boost gauge. Attach the gauge to your dashboard with the correct gauge mount for your car, then take it for a test drive to check that your gauge is working properly.
