And if I never make another one I'll be happy. If offered for sale, pound-for-pound, this would be the most expensive item I make by far! Over 5 hours of machine work in this lil gem. Way more than gold or platinum so don't even ask.

One thing this does do is smooth and streamilne the inlet air even more than the o-rings and allows me to make mm fractional sizes which arent available with o-rings. Cool thing about this is it ramps output voltages measured on an oscilloscope very very linearly with no dithering whatever. I mean PERFECTLY smooth voltage ouputs... almost digital quality outputs. In fact indiscernable from a mock digital ramp on the scopes 4" diameter circle screen even under 8x magnification (max).

And while it's a nice toy and I'm glad I made one it's a pain to work with... far too tiny for my liking. It can't be installed/removed with the sensor as it won't fit thru the sensor hole in the MAF body even if bored out... too long. So it's just pushed in for this pic. The next pic will show it installed in the MAF housing which required me to make a special "alignment tool" so it was perfectly aligned with the sensor bore when installed. All fretfully small &amp; painstakingly fiddly stuff.

And it's perfectly sized to my cars elevation, injectors and ARC-2 needs. It is VERY custom-made for me specifically for maximum performance and acceleration. But everyone on the o-ring list will get an o-ring that is within .2mm of this VS's inside diameter. But WHAT a difference .2mm makes (thats only a net I.D. difference of .0078"). O-rings will certainly get ya close... VERY close, even better than the car came with when new. But that wasn't good enough for me. But if this one got lost tomorrow there's no way I'd make another! And making this in 5 different sizes in .1mm bore sizes for testing only added to the frustration. There were several times I wanted to SCREAM!

 

It looks like a piece a watchmaker could make.

cannot take good pics of this thing. No flash and it reflects the black around the sensor wires and with flash it whites out completely due to gloss.

And yes I polished it to slow the air down as it was a smidge too fast with a brush-finish. Easier than re-fixturing it and changing the inside diameter. On this small a piece just polishing or brush-finishing yeilds HUGE HUGE differences in air velocity across the sensor stem, ie; brush finish incresases velocity while polishing slows velocity.

 

I know why it's there, but did you make it or did you find something that fit so well?

 

then "parted" it from the end of the rod and epoxied it to the sensor tip.

 

Im jelous of your skill

 

enlighten me please.

 

This allows the sensor tube in the MAF housing to be round/radiused on both it's horizontal and vertical axis.... no sharp edges whatsoever. Essentially an airfoil, designed to provide a reduced/diminished reaction to surrounding air while remaining stationary relative to the motion of that air rushing over or around it.

 

Impressive

 

Can you make it in neon??
