If you have a turbo in your car, and you want to see the charging pressure, then we have several variants of turbo charge pressure watches. All are of high quality, at reasonable prices. They are easy to mount on the dashboard. We have manometers that can measure up to 3 bars, for people running very high charge pressure.
Turbomanometer mounting
Mounting the turbo manometer is very easy. It just needs to be mounted in the cabin with a 12v ignition plus and a frame. Then pull the vacuum hose out into the engine compartment where you mount it on a socket in the manifold. If you do not have a spout free you can buy this vacuum T-piece and put in between another hose.
