Mangoletsi head port injection fitting

[Quattrofrank]

Hi

Finally starting to work on my project again after sitting for 8years
I have the mangoletsi port head manifold and I`m struggeling to see where to fit the water temp and air temp sensor on the manifold. It has a few plugged ports on the underside, but I think its only for air (so air temp sensor could fit), but what about the water temp sensor? I seems the whole company has gone away so cannot find any instructions. Also the throttle body sensor needs fitting, seems to fit pretty good on the last throttle body (closest to the firewall)
Hope someone here has it fitted and can guide me. Im going fuel injection so that why I need theese sensors connected

Have you seen these videos? Perhaps they have the information you are seeking.

you are a hero, this helps a lot.
I dont understand why he want the air temp sensor with the air filter instead of just using the air gallery in the manifold. Would think that is more accurate

An air sensor which is screwed directly into a metal engine manifold will slowly soak up the engine heat from the manifold. It'll read correctly when you are warming up but will give artificially high temperature readings once the engine has warmed up. A later hot restart may also be problematic as the computer will want to apply a leaner mixture with these false (higher) readings.

Mounting it in the airflow but in an insulated position removes this heat-soak issue.

Appended is a graph showing this. On the left is a normal drive from t=160seconds to t=849seconds. There is then a 20 minute break in the middle of the graph and it resumes from t=2400seconds to t=3100seconds.

During the break, you can see on the top graph that coolant temperate drop a bit and the temperature at the bottom of the radiator drop significantly. You can also see on the bottom graph that the air temperature in the airbox and inside the manifold jump significantly. The air temperature at the bonnet mouth remains unchanged.

kind regards

The air temperature sensors for fuel injection are designed to react very quickly to changes in air temperature and are insulated from their mounting so the temperature of the manifold is irrelevant. They measure the temperature of the air entering the cylinder at that moment in time so will enable the ECU to correctly calculate the fuel and timing appropriately.

Mounting in the air gallery of the manifold has to be more accurate but in a non-forced aspiration engine mounting in the air filter will give a reasonable approximation if mounting in the manifold is physically difficult.
