MAF after the compressor or before the compressor

[nismo1003]

My friend put his after the compressor on his turbo maxima, and he said some MAF doens't like pressure , wondering if I should put it after or before the compressor?

[voddka]

The MAF should be between the intake and the compressor side of the turbo. Where the hell would he put it on the turbine side?

Before...it's just a lot easier to get right. the Element should be 16-18 inches from the turbine blades is the advice I was given.

that’s what I was wondering

[Mikel]

A lot of people with GN's have moved the MAF to the pressure side and noted more accurate fueling, and better throttle response.

Of course, different car, different engine management, etc.

[Mikel]

The turbine side would be in the exhaust.

no, after the compressor, before the ic/ or after the ic before the tb.

Its called a blow through system i believe. It has been discussed in the SR forums so you can search for it. But from what I understand, you need a piggy back fuel computer like an SAFC or something, the stock ecu won't work right.

Blow through MAF's have been discussed here and on Freshalloy. It does work. There is no big benefit to doing so. Only, if you run a BOV in front of the MAF somewhere(not too close as to disrupt the reading) you can run an open BOV with no stalling issues. Stillen's S/C kit for the Maxima usues a blow-through set up. It appears even the Greddy Turbo kit for the 350Z is doing the same thing. And no compensation should be necessary though any ECU or piggy back so long as the air going through it is smooth and even. The same caution should be used in providing smooth flow through the MAF in a draw-through or blow-through set-up.

Some members of the 240sx community have tried and successfully used a Blow-through set-up with no adjustments.

That's great news!

Any concern that the MAF sensors could be damaged by the pressure?

Not from me...(I have a blow-through MAF car that has been running fine for 21 months and 30K miles). It isn't like we are running lots of pressure through there.
