Without the flow straightening screens, as fitted to the sensor OEM, the accuracy of the sensor over the required flow range of the sensor calibration is no longer within the calibration/accuracy specified for the sensor performance. There is no way to know how the calibration is effected, except that it is no longer accurate according to the flow calibraton. Turbulant flow conditions, are by nature chaotic, therefore, the sensor output becomes chaotic when the laminar air flow screens are removed.

Thats kinda what I was thinking. I know people have run these for years without probs, just seems to me it might smooth things out a little when it comes time to tune.




Agree. Maybe I can talk buddies at VAC Motorsports into showing me how the flowbench works. Have to read up on powering the maf though. Cant be as easy PC power supply and voltmeter?
Wouldnt be able to use the airbox though. This maf is 85mm straight through so tough to fit.

Bout an hr west of philly

Nice! I love going down there.
Great people and lots of cool shit going on in there. And the Bocce club around the corner makes a mean cutlet and greens sandwich, lol.

I dont think any of that applies on our cars and dont have any of them. Just a straight 85mm housing with a hitachi maf.

I dont really know a whole lot about this or if a bench will even flow the gram/sec that our motors can eat. So not sure close you could get to an actual calibration like this.

I am just curious if there are any nasty (turbulent) spots that the straightener would smooth out. Should be able to see some trends an decide from there.
