Evening out turbulence in a 3" pipe
Hi folks,
I have a small problem. In my car I'm building new pipes for the pressurized air. On a straight pipe there is a MAF sensor (Mass Air Flow). It consists of a hot wire and a temperature sensor. After the pipes were redone and the MAF sensor was moved to the pressure side and after the intercooler I experience problems with an uneven signal from the MAF sensor. This is certainly caused by turbulence in the air passing through it as these sensors are very sensitive to that.
This is causing the engine to have problems injecting the correct amount of fuel in low load scenarios causing the engine to run uneven and almost stall in some cases.
So basically I need a way to straighten out the air as easily as possible. Honeycombs usually perform this job well, but I can't imagine gluing a honeycomb to the intake of the MAF sensor can become any good. There is already a steel grid in the intake for correcting minor turbulences.
My idea is welding two plates in the tube before the MAF sensor somewhere. I'm also open for other suggestions. I've made a drawing to illustrate the problem:

Are you physics folks able to guess what the best solution is? I have really no experience or know any theory about turbulence, so I need some help on this :).
Thanks in advance,
Christian
