MAF Location?

[L67PSI]

Hi guys,

I'm mocking up a mace style cold air intake enclosure and wondering if MAF can be inside box, or better suited closer to throttle?
Car is a VT L67.

Cheers

Close to the throttle is best for least delay, but the delay would be in ms time scale so I doubt it would be noticeable.

What about heat soak?

[vlad01]

They are heated wire and have a temp diode? so that automatically accommodates in temp differences in the air stream.

You dont want air vibrations from the valves causing air to cross the wire twice and be double counted. Observing if this is happening is hard if not impossible but its worth keeping in mind. Thats why factory intakes often have wierd looking bulbs hanging off the side of them. They are tuned to absorb those vibrations. In practice though, this probably wont be a problem.

Didn't someone on this forum have issues with the MAF readings when MAF was right in front of the TB? I just can't seem to remember whom it was.

I remember that many moons ago a guy on the JC forum (greenfoam) was experimenting with a split plenum manifold on a 3800 V6, he did this by cutting the standard manifold almost in half and welding in a alloy plate to separate the plenum into 2. It made a horrendous racket when it was fired up because the alloy plate was quiet thin and the harmonics inside the intake manifold seemed to be flexing the separator plate.
