I hate inconsistency

  The 930's air cleaner box has a small square hole in it. The MAF sensor I made has an 80mm outer diameter. I'm an old man and I don't need power but I don't like the inconsistency. I cut out the square hole into a big circle.

  Air funnels are needed to smooth out the intake air.　I made an air funnel.　All you need is a sewer pipe , a burner, leather gloves, and a little burn.



  The test drive was fine.　When driving very gentlemanly, I felt some discomfort between 1000 rpm and 1500 rpm.　Porsche will tell me not to drive below 1500 rpm, but to me that needs improvement,It is.
