Digital Manometer

I like to use the good old mercury sticks to sync the throttle bodies, no batteries required!

 

Build your own, very simple. Fluid I used is 2 stroke oil. Adaptors and T pieces to suit your vacuum lines. Works well and balancing the throttle's made a noticeable difference to the smoothness of my 412.

Somewhere in the past someone posted a laptop oriented assembly to do this.
Being an old motorbike guy this is what I use. It works great on the 308.
I tried to download a video, not that it would have changed anything, but I couldn't figure it out.
This uses mercury which I do understand is getting hard to find. I have a friend that works in a lab who helps with it.

Cheers,

Wow. I just used to use a hose up to my ear and listen to them.

 

This is the 12 cylinder digital manometer made by an Fchatter...

Cool, a tool that costs $1000 with all of the problems of a computer that replaces a simple easy to use tool that never crashes or breaks that cost me $30.

 

can the oil be ingested into the intake if it goes out of balance?

 

Two stroke oil would eventually burn away without leaving any residue.

 

UK company makes these. Uses polished stainless rods in glass tubes. I have used it for Ferrari and Bikes and back to back with a mercury manometer and it is acurate. Great thing is you simply lay them down in your toolbox and store them without loosing any fluids. Impossible to ingest into the engine.

Are these for sale and is there a web site?

 

The top link (101) will take you to his web page which has contact details. Harald is an fchat member, so you could also pm him. User name is hoverland I think. He sells the device.
