Another MAF location question…
A few hypothetical questions on MAF location.
On normal NA application MAF is before throttle body and works as draw through. Response is good with some aftermarket air filter / air bridge combos moving MAF closer to throttle body.
Then on supercharged / turbocharged applications most common layout is blow-through.
My question is has anyone tried MAF after throttle body? This is for remote throttle application. With 90mm TB and 85mm MAF correct tapering or velocity stack effect can be maintained.
Concerns are:
* Response, but then MAFs respond slowly to start with.
* Laminar or non turbulent flow.
* Additional volume after TB
Is there something that would preclude this, or has no one simply not tried it.
Thanks

Layout is TB > MAF > Supercharger > intake.
Oh, like the new hairdo.

This would most likely cause the MAF to throw an out of range code. It would be a major pain keeping the elements clean.
