I took the day off with my engineers here in Switzerland,
the topic with the MAF's to study it.
The air mass is not a problem.
The two pipes before the compressor is in the size and length OK.
Important here is the installation of the supplied by STILLEN apron,
or the air to lead not directly to the air filter.
Turbulent air flow.
We think, the only problem is the temperature measurement.
As soon as my "Z" from the engine conversion comes back, we will be at the Intake- Plenum install a temperature sensor capable of measuring the effective inlet temperature. So I can compare the two measurements and, if necessary, correct the MAF- temperature.
At the moment we do not yet know how?
I will continue to report in the spring.
See you soon and happy holidays from Switzerland
