manifold pressure

how to connect on manifold pressure sensor on jab 3300, to have an indication on a dynon

Manifold reading.

 

Make a spacer to fit under the carb and have a small pipe sweated/threaded into it. The bore can be quite small. This would be to avoid changing the manifold if you don't want to use it later in the aircraft. Sorry, I read that as DYNO.

 

SO,.. Carefully weld a suitable union on the manifold to accept the fitting Dynon supply Just make sure that it is not in the way of anything. You would have to remove the manifold from the motor to do this proprely.Nev

At the bottom of the Bing carb, right below the butterfly, there is already a connection for manifold pressure. It's blocked with a small screw, just take it out and push a 5 mm ID tube on. Look in the tuning service bulletin JSB 018-2, on page 5 there is a cut drawing, showing the MAP sensor port as #51.

thought there might be.

most carbs do have such a provision but I was not sure in respect of the Bing CV. Nev

I was told the manifold pressure here varies alot and an orifice may be required to dampen this down so a good reading can be had

The take off point on Bing's is not quite manifold pressure but so close to near enough that it doesn't matter. Manual Manifold Pressure gauges seem to read O K without a damper. Electronic sender units may need a rod (brass?) with a 1/64" hole in the tubing. If you have a fuel flow guage as well you can get meaningfull performance figures.
