what needs a vacuum source?

[matt walters]

Hi guys

Just wondering what actually needs a vacuum supply to it that comes stock on the car.

The things i assume need one are the

-brake master cylinder
-steering rack
-fuel regulator

Is there anything else either mechanical or sensors that need a vacuum supply to them?

I no longer have stock inlet or tb this is why i ask.

rep added for help

Thanks Matt

All those you have mentioned plus:

Map sensor
Boost gauge
External wastegate if running one
Dump valve

Yeah i know those mate thank you.

Was more on about any other sensors etc like the ones that are next to the coil pack?

If they aren't needed can the sensors themselves be removed?

The valve on the steering rack is for increasing the engine idle speed when the steering is on a full lock, it's not necessarily required.

If your not using the stock ECU, EVAP system and air conditioning, then all you really need to have piped to the manifold side of the throttle body is the brake servo, fuel pressure regulator, MAP sensor, boost gauge and BOV (if your using one). Boost control i.e. actuator/wastegate should be piped to the compressor housing of the turbo.

Using an emu so is that the same? Got 3 bar map sensor obviously
