[s-cars] MAF to intake side of turbo

[Paul Gailus]

One advantage with having the MAF ahead of the turbo is
that if a boost hose blows then the ECU can sense that
something's wrong and keep the turbo from overspinning.
The Motronic compares the measured airflow vs. the speed-density
and shuts things down if this corresponds to an impossibly high
volumetric efficiency.

Honetly from what I have seen, we all do run speed density over..4000rpm
at full load with most of our slightly modified cars.

I talked to Mihnea at length about this, cuz I thought no, but he has
done it, and the real concern is....first custom software, as well you
now have a blow off valve, not a bypass valve so you have to tune it
properly to allow this condition.  Honestly at that point, I don't know
why you would even want to use a maf.

Hey guys, I've been reading about a few guys in the UK moving the maf to
the

intake side and having no issues. Anyone done this yet here? I am
thinking 

of moving mine to the intake pipe just before the intake manifold right
before 

where the ISV goes in. This will let me free up the turbo cold side and
go to

a  4" intake. Thanks for any input.
